Why Carrier’s Comfort 15 Heat Pump is a Smart Investment

Blog, Heat Pump Services, , , ,

With winter on the horizon, many homeowners are dreading the high utility bills they’ll face for indoor heating. Some believe these costs are a necessary evil, but improvements in heat pump technology have proven otherwise. Indeed, heat pumps increase central heating systems’ durability, decrease their environmental impact, and boost their efficiency to slash energy bills. The Comfort 15 Heat Pump from Carrier, in particular, leverages impressive efficiency at an affordable rate. Consider the benefits of a new heat pump installation when your outdated unit costs you a fortune.

For over 45 years, R. A. Dobson has provided Ashburn, VA, homeowners with effective HVAC, water heater, and plumbing solutions. Highly trained technicians perform our installation and maintenance services, and we honor all manufacturer warranties. For headache-free and satisfactory heating solutions, call (703) 481-3700 today. 

Below, we discuss why the Comfort 15 Heat Pump is for you:

Carrier 15 Heat Pump Features

  • Efficiency: On the SEER2 (Seasonal Energy Efficiency Radio) rating, heat pumps are scored on their ability to heat and cool, with higher SEER2 scores representing greater efficiency. The Comfort 15 boasts a SEER2 score of 15.2. In comparison, units that are 10+ years old are likely to have a SEER of around 10.
  • Durability: Dents, scratches, and outdoor wear-and-tear are no match for the galvanized steel cabinet, heavy-duty wire coil guard, and baked-on powder paint of the Comfort 15 Heat Pump. Manufacturers can also fit comfort series models with WeatherShield™ technology for long-lasting corrosion resistance.
  • Hybrid Heat System: Like other Carrier heat pumps, the Comfort 15 design is hybrid heat system compatible, which can help you save on utility bills during the winter. By combining this electric heat pump with a Carrier gas furnace and compatible thermostat, the Carrier Hybrid system automatically switches between electric and gas heating to optimize the system’s efficiency. For example, when the temperature drops below 40 degrees, the heat pump turns off and the gas-fired furnace kicks in. This innovative dual-fuel system ensures maximum year-round comfort.
  • Eco-Friendly: Carrier was the first manufacturer to offer systems with Puron refrigerant, a contemporary solution to environmental concerns. Older heat pump models use the refrigerant R22, a substance that contributes to harmful ozone depletion. Replacing an older, less efficient heat pump with a Carrier product thus reduces energy use and your environmental impact.
  • Low Sound: Comfort shouldn’t come at the expense of your hearing. In addition to optimal temperature control, the Carrier 15 has a quiet operation that goes as low as 69 decibels (for reference, normal conversation is between 60-70 decibels). Protect your ears by opting for a heat pump designed with your comfort in mind.

Innovation at an Affordable Price

Heat Pump Installation Ashburn VA

Air conditioners, furnaces, and heat pumps typically last between 15 and 20 years. After years of wear and tear, they lose their temperature control efficiency, which increases energy bills and expensive maintenance. So, rather than wasting money on repairs for an inefficient and antiquated heat pump, enjoy the Comfort 15’s long-term energy savings. Heat pump installation costs incurred by this upgrade are offset by reduced energy consumption and a higher durability standard.

4 Ways to Extend Your HVAC’s Lifespan

Air Conditioner Installation, Air Conditioner Repair, Blog, , , ,

Maintaining a comfortable and healthy living environment in Ashburn, VA, homes demands a functional HVAC system. While our region’s winters are relatively mild, the summers come with significant heat and humidity—home HVAC regulates those levels while also filtering out pollutants and allergens from indoor air. Yet these operations take a toll, and replacement systems can be expensive. Therefore, routine maintenance—including professional thermostat repair—protects their functioning and ensures homeowners receive the full lifespan their HVAC system’s manufacturer promised.

R. A. Dobson’s HVAC and plumbing experts are eager to help homeowners in Northern Virginia improve and maintain their indoor comfort. A Carrier Factory Authorized Dealer, R. A. Dobson is a 2nd-generation, family-run service provider with decades of experience. All our services come with a 1-year warranty, and we honor all manufacturer warranties. Call (703) 481-3700 to schedule a service appointment and get the latest energy-efficient HVAC technology!

Below, we explore four ways you can extend your HVAC system’s lifespan:

  1. Regular Maintenance

The foundation of HVAC longevity is maintenance. Routine maintenance can identify potential issues before they become significant problems and ensure the system runs efficiently. Appropriate care includes cleaning system components, replacing air filters, and checking refrigerant levels. We recommend at least one annual professional servicing before the heating or cooling season starts.

While regular maintenance entails upfront costs, its benefits include long-term savings. In addition to a preventative measure, upkeep makes HVAC systems more energy-efficient, which can result in lower utility bills. R. A. Dobson offers service scheduling so you can set up appointments well before heavy-usage seasons!

  1. Thermostat Repair and Upgrades
Thermostat Repair Ashburn VA

Upgrading your thermostat is among the easiest ways to extend your HVAC system’s lifespan. Traditional, non-programmable thermostats are limited in functionality and can cause wear and tear on your HVAC system. Yet smart thermostats can improve system efficiency, cost savings, and home comfort thanks to a range of features traditional thermostats lack, including programmable settings, remote access, and even the ability to learn your temperature preferences.

Although smart thermostats have a higher upfront cost than traditional ones, the former pays for itself through cost savings. Still, professional installation is vital for both analog and smart thermostats. Hiring a licensed contractor ensures you receive a functional system, while improper installation can lead to malfunctions or expensive thermostat repair costs. You can contact R. A. Dobson for reliable smart thermostat repair and installation.

  1. Airflow Optimization

Proper airflow is crucial for the efficient operation of your HVAC system. Poor airflow reduces system performance, boosts energy consumption, and increases utility bills. Optimizing airflow entails a few simple steps:

  • Remove blockages around your air registers. Furniture, curtains, and other typical household items can block these outlets, making it harder for your HVAC system to distribute air throughout your home. Clear your vents of any obstructions to ensure proper airflow.
  • Change your air filters regularly. Dirty air filters can restrict airflow and add strain to your HVAC system, yet changing them out improves the airflow and extends the lifespan of your HVAC system.
  1. Try Alternative Methods of Heating and Cooling

Despite HVAC’s fundamental role in modern home comfort, it is not the only way to control indoor temperatures. Everyday home accessories—windows, fans, blinds, and curtains—can cool interior environments so that HVAC systems need not work alone in temperature maintenance. 

If you want to invest resources into home comfort, speak to R. A. Dobson technicians about how heat pumps and humidifiers can help. Both are available through Carrier, and professionals can install them to work in tandem with HVAC systems.

The Best Carrier Air Conditioners for Your Home

Air Conditioner Installation, Blog, , , , ,

Carrier has manufactured indoor cooling units since their founder, Willis Carrier, invented the first modern air conditioning system in 1902. The company is now a leader in home comfort products, ranging from air conditioners to furnaces. If you want to invest in a new air conditioner before summer begins, look no further than the Carrier Comfort 15, Carrier Comfort 16, the Infinity 18VS, and the Infinity 19VS. Moreover, R.A. Dobson’s reliable air conditioning installation team can install your new unit at a low price so you can stay comfortable year-round.

A 2nd-generation family business with decades of experience, R.A. Dobson provides air conditioning installation—among other home services—for Ashburn, VA, homeowners. Our handiwork endures, and our service exceeds expectations every time. To contact an air conditioning installation professional, call (703) 481-3700 or visit our website today.

Below, we detail some of the best Carrier air conditioners available:

The Carrier Comfort 15

Anyone looking for simple, efficient, and affordable cooling need look no further than the Carrier Comfort 15 air conditioner. Given a seasonal energy efficiency ratio (SEER) rating of 14 and an affordable price, it checks every box. It has a single-stage scroll compressor—a specially designed compressor that works in a circular motion rather than an up-and-down piston action—and comes with WeatherArmor protection.

When you upgrade from a less energy-efficient system to one such as the Carrier Comfort 15, your energy bill will shrink. This model balances budget limits and a desire for long-term energy savings. Moreover, its quiet operation is gentle on the ears—as low as 72 decibels!

The Carrier Comfort 16

Equipped with up to 16.5 SEER efficiency, the Carrier Comfort 16 has an eco-friendly refrigerant and high- and low-pressure switches for optimal cooling. Like the Carrier Comfort 15, it uses a single-stage compressor to give you the most bang for your buck. It’s a heavy-gauge, galvanized steel construction with a baked-on powder coat paint. 

Carrier units utilize Puron refrigerant, an environmentally sound option that doesn’t deplete the ozone layer and comes at a low lifetime service cost. The Carrier Comfort Series air conditioners also have a 10-year exchanger limited warranty.

The Infinity 18VS

Heat pumps, similar to air conditioners, are installed outside to heat or cool your home depending upon the season. The Infinity 18VS heat pump offers variable-speed compression, and its low speeds create quiet operation. Its long runtime allows hot and cold indoor air to mix and create a comfortable temperature. It has a SEER rating of 19 and requires no excess electricity—what’s not to love?

The Infinity 19VS

Air Conditioning Installation Ashburn VA

With its small cabinet and 19 SEER rating, the Infinity 19VS Carrier unit offers a high-efficiency, variable speed performance. The variable speed inverter capacity control delivers up to 5 stages of operation for exceptional load matching, dehumidification, and zoning performance. It works with many indoor units and controls, fitting seamlessly into any household.

Its Infinity Control allows you to program your system’s settings and remind you when to conduct maintenance. Chat with a professional air conditioning installation team if you have questions about air conditioning repairs, replacements, and more.

Take Control of Your Home’s Temperature with a Smart Thermostat

Blog, Thermostats, , , ,

Home automation has transformed the stuff of science fiction into many homeowners’ realities. This “smart” technology allows residents to control integrated devices and systems in their homes through a phone, tablet, or other internet-connected devices. Among the likes of remote lighting control, keyless entry, and automated security systems, one of the most popular home automation features is the smart thermostat. Learn more about it and seek professional support for any smart thermostat repair or installation.

Below, we describe smart thermostats’ functioning, features, and benefits:

How Smart Thermostats Work

While smart thermostats are the most cutting-edge type on the market today, manufacturers also offer non-programmable and programmable thermostats. The former allows users to shut their HVAC system on or off and adjust its temperature manually; the latter grants the ability to create distinct temperature settings for different times and places in their homes.

Smart thermostats build on the capabilities of the other thermostat types by incorporating a computer into their design. Once connected to Wi-Fi, the smart thermostat can be adjusted remotely, generate notifications, and even integrate with other smart home devices.

Popular Features

  • Programmable temperature settings: Again, users can pre-set smart thermostats to run at specific temperatures during certain times. For instance, during winter, you can have the heat turn on at the same time you wake up each morning. You can also set the interior temperature low during the workday and raise it automatically when you return home.
  • Machine-learning capabilities: These systems can also learn your heating and cooling habits, then anticipate your needs. This capability can save you the necessity of programming your device for every shift in the season. Plus, it optimizes energy use and saves money on your monthly electricity bill.
  • Safety features: Linking your thermostat to smart smoke alarms allows the latter to shut off the HVAC system when it triggers. HVAC systems can worsen the severity of house fires by blowing air around, so this setting helps protect your home.
  • Voice controls: Depending on the type of thermostat you purchase, your system may respond to voice commands through Apple’s Siri, Amazon’s Alexa, or another chatbot. This functionality saves you the trouble of even opening your phone—just call out instead!
  • Energy tracking: Compared to all their other functionality, smart thermostats’ energy-tracking capability seems negligible. Yet this feature can help you determine your periods of highest energy use, which can be the focus of your energy-saving strategies.

What Smart Thermostats Can Help Homes Achieve

Thermostat Repair Ashburn VA

Given the sheer range of features, a smart thermostat can provide your home with numerous benefits. Programmable temperature settings offer clear energy- and money-saving incentives, but this technology can also lengthen your HVAC system’s lifespan. HVAC units last around 15-20 years, though the decreased usage that smart thermostats facilitate can ensure homeowners receive that timeline and then some.

Furthermore, voice controls make your home automation devices more accessible. Senior loved ones, for instance, might struggle with complicated temperature controls yet have no problem commanding a smart device to adjust a setting. Last but not least, energy tracking capabilities give homeowners increased insight into their carbon footprint and a place to start reducing it.

Humidifier Repair Ashburn VA

Signs Your Home’s Air Is Too Dry

Blog, Humidifier Installation, HVAC Inspection, , , , ,

Households that rely on a heating system during the winter tend to struggle with the effects of dry air. Not only is it uncomfortable to breathe, but it also dehydrates residents’ skin, produces static electricity, and even damages wood furniture and floors. If you’ve noticed these signs in your home, it may be time to invest in a humidifier to add moisture back into the air and improve the overall air quality. Call a humidifier repair technician to install, maintain, or repair your system.

R.A. Dobson offers such services to Ashburn, VA, homeowners. With over 45 years of experience, R.A. Dobson has the knowledge and skills to diagnose and repair your humidifier and other interior climate systems. Our team of skilled technicians seeks to deliver outstanding customer service on every job. For a free estimate on your humidifier repair, visit our website or call (703) 481-3700.

Below, we discuss some common signs of dry air in a home:

Dehydrated Skin, Throat, and Lips

Dry air can leech moisture from human skin and mucous membranes, leaving your skin feeling itchy and your throat scratchy. Affected skin appears most often on the face, hands, and lips (which take on a parched and chapped appearance). Moreover, dried mucous membranes in the nose and sinuses become inflamed, which results in a stuffy nose and sinus congestion.

Respiratory Problems

Humidifier Repair Ashburn VA

Dry air can irritate the respiratory system and make breathing difficult, especially for anyone with asthma or allergies. Inflamed mucous membranes lead to coughing, sneezing, and difficulty breathing. Even worse, dry air promotes the spread of viruses and can simultaneously weaken the body’s immune system, making you more susceptible to colds and the flu.

Static Electricity

Dry air can also create more static electricity in a room, which jolts anyone under your roof when they touch metal objects or walk across a carpet. When a room’s air lacks electron-dissipating water molecules, the surfaces therein have a greater chance of producing static electricity. This effect is irritating and can create problems with computer keyboards, touchscreens, and other electronics.

Issues with Home Systems and Structures

Finally, your heating system can be affected by dry air. The less moisture in a climate, the more a heating system must run to maintain a comfortable temperature. This process, of course, creates high energy costs every month. 

Moreover, dry air can dehydrate wood. Although it usually absorbs moisture from the air, wood becomes parched if the air lacks humidity and loses its structural integrity. It becomes brittle and cracks, which appears as damage to wooden furniture and hardwood floors.

Professional Humidifier Repair Service in Ashburn, VA

To optimize your home’s air quality and alleviate allergy or respiratory symptoms, use a humidifier to add moisture to the indoor climate. Humidifiers make the air in your home comfortable and healthy but must be used correctly, cleaned frequently, and maintained regularly to ensure they function safely.

5 Tips for Extending Your HVAC’s Lifespan

Blog, HVAC Inspection, , , ,

As we approach another scorching summer, take a minute to schedule an HVAC maintenance and inspection service from R.A. Dobson. Doing so can extend your system’s lifespan and keep it functioning throughout the year’s hottest months. A few further practices—such as installing a high-quality filter, giving your unit clearance space, and keeping your home’s registers open—will ensure you get the best performance from your HVAC system.

R.A. Dobson is a 2nd-generation, family-run organization and a stalwart service provider for folks in Ashburn, VA. Our technicians are enthusiastic about their work because they know it supports everyday homeowners and families. Moreover, all our employees carry licenses and insurance to guarantee we deliver on our promises. Call (703) 481-3700 or visit our website to schedule a service appointment today!

Here, we outline some tips on how to protect your HVAC’s functioning:

1. Install a High-Performance Filter and Check it Monthly

Should it start operating less effectively than it once did, or do so at a higher cost, your HVAC may require repair or replacement. That said, a simple filter replacement may be the solution. Consult a professional and ask about a high-performance air filter.

The market’s new and improved filters outperform those made decades ago. Recent models have allergen reduction capabilities, enhanced materials, and high-efficiency ratings. Both you and your HVAC system can benefit from installing one.

No matter what quality filter you have, check it every month. If its surface appears dirty or stained, it requires replacement. Additionally, homeowners with pets that shed often may need to change their filter monthly. If you are unsure whether to replace your system’s filter, contact R.A. Dobson for a professional HVAC inspection.

2. Provide Ample Clearance and Clear Debris

HVAC maintenance Middleburg, VA

While you need not know every aspect and component of your HVAC system, you should recognize whether it has indoor and outdoor elements (as opposed to a window unit). Central HVAC system parts include air ducts, an indoor evaporator unit, and an outdoor condenser unit. These constituents require simple care.

To start, evaporators and condensers require ample open space. Thus, leave no objects or belongings leaning on these units. Likewise, avoid planting trees or shrubs around the condenser. In general, two feet of clearance is sufficient.

Furthermore, remove any detritus that land on these units. Condensers, in particular, tend to collect leaves, sticks, and other debris from their surrounding environment. Some quick cleaning will keep them clear and functioning.

3. Keep an Eye on Refrigerant Lines’ Insulation

Refrigerant lines are another crucial element of central HVAC systems’ functioning. They carry refrigerant fluid into evaporators, where the liquid pulls heat from interior air. That said, these lines should be insulated and intact to preserve their cooling capabilities. Missing insulation—or a broken line—will hamper your HVAC system’s efficacy.

If you notice a problem with your lines, contact R.A. Dobson for maintenance services. We can correct the problem and ensure your system continues to run without a hitch.

4. Make Sure Your Condenser Unit Remains Level

Although it may sound a bit silly considering the bulkiness of condensers, ensure your unit remains balanced. While evaporators sit inside a stable environment with little risk of tilting, condensers may lean due to outdoor conditions.

A technician can help you check that your unit sits on level ground (without any breaching tree roots) and may offer pads to solidify its stance.

5. Keep Your Home’s Registers Open as Much as Possible

Central HVAC systems have registers at the end of air ducts to give a building’s occupants control over the air that enters a room. Closing one register prevents cool air from penetrating a given space. However, closing the majority of a home’s registers can strain the system. Rather than doing so, consider adjusting your interior temperature.

5 Ways to Make Your HVAC System More Efficient

Blog, HVAC Inspection, , , , , ,

Heating and cooling bills are among the largest expenses in most homes, so everyone wants to minimize these costs. But how can you increase your HVAC system’s efficiency? Some proven methods include adjusting your thermostat to the season, closing curtains and blinds, and keeping vents unobstructed. Most importantly, hire a professional for a thorough HVAC inspection annually to ensure your system continues functioning at high capacity.

R.A. Dobson is a heating, air conditioning, and plumbing company that operates in Ashburn, VA. As a 2nd-generation family business, we understand the ins and outs of owning and managing a home. This knowledge helps us provide the outstanding support, guidance, and customer service that our satisfied customers report. For more information on how we can help you, contact us at (703) 481-3700.

Below, we outline 5 ways to make your HVAC system more efficient:

Adjust Your Thermostat to the Season

As the outdoor climate warms and cools throughout the year, make a note to adjust your thermostat accordingly. During the summer, reset the indoor temperature to between 5-8 degrees higher than your “normal” level. In the winter, reset the temperature in the opposite direction.

You might find a programmable thermostat helpful in this effort. You can use its capabilities to automatically adjust the temperature for different seasons, times of day (like when you’re away from home), and even rooms in your home.

2. Maintain Accurate Thermostat Readings

Consider installing separate thermostats on different levels of your home so that each can provide as accurate a reading as possible. Doing so not only increases your HVAC system’s efficiency but also allows you to administer different temperatures at different levels of your home. Programmable thermostats can automatically accomplish this zoning effect for optimal energy efficiency.

Also, refrain from placing heat-producing appliances close to your thermostat. Doing so could compel your HVAC system to cool your home further than you wish. During the winter, a proximate heat-producing appliance to your thermostat would make your HVAC system use less energy but also make your thermostat inaccurate.

3. Close Your Curtains & Blinds

During the summer, close your curtains and blinds to prevent sunlight from heating your home’s interior. This effect occurs in the same way that the sun heats a car. By closing your curtains and blinds on hot summer days, you block the sun’s rays. Doing so can help you save on air conditioning costs.

Additionally, closing your curtains and blinds during the winter prevents cold air from seeping inside through the windows. Only open your curtains in the winter when sunlight is coming through and angle your blinds up towards the ceiling.

4. Use Heat-Producing Appliances Sparingly & Keep Vents Unblocked

Heat-producing appliances, like the oven and dryer, generate warm air. So, using them during the hottest time of the day forces your HVAC system to work harder to cool your house. Try to plan out how you use heat-producing appliances accordingly.

Also, keep your air vents unobstructed so that your HVAC system can do its job. This requires moving various items, like furniture and toys, away from all indoor supply vents. Doing so will promote steady airflow and prevent your system from overworking.

5. Hire a Professional HVAC Company

Finally, employ a service company to provide maintenance as well as parts repair and replacement for your HVAC system. A capable HVAC professional can handle all your system’s complex needs, including cleaning your outdoor condenser unit, vacuuming indoor vents, clearing your drain line, and insulating exposed ductwork.

When to Repair and When to Replace Your HVAC System

Air Cleaner Installation, Air Conditioner Repair, Blog, , , , ,

A reliable HVAC system is essential to comfortable indoor living. Moreover, regular maintenance helps keep that system in optimal condition. But what should you do when your system ceases to work? To determine whether your HVAC system requires a simple repair or full-scale replacement, consider its age and operating status as well as unusual changes in its behavior. A trustworthy HVAC company in your area can determine what your system needs.

R.A. Dobson offers HVAC repair and replacement services in Ashburn, VA. A second-generation family company operating since 1975, we offer a 1-year service warranty and honor all manufacturer warranties. Our trained and certified technicians provide outstanding service and aim for customer satisfaction. Contact us today at (703) 481-3700!

Below, we consider several questions, the answers to which indicate whether you need an HVAC repair or replacement:

  1. How Old Is Your HVAC System?

Air conditioners, furnaces, and heat pumps all have a lifespan of about 15-20 years. Yet their exact lifespan depends on each system’s environment, brand, model, maintenance, and use. 

You should consider units at less than half the age of their life expectancy worth repairing once. However, further breakdowns indicate a need for replacement. You should also replace units that require repairs amounting to more than half the cost of replacement. 

Additionally, outdated models can pose problems even if they still operate properly. For instance, furnace models from before 2015 have a lower efficiency compliance level than models from after, which can result in higher energy bills. Also, air conditioners that use Freon should be replaced, as the US no longer allows the production of Freon.

  1. Is It Operating Effectively?

Inconsistent temperatures throughout your home may signal that you should replace your HVAC system. As your system ages, it loses its ability to create an even temperature throughout your home.

Some issues—such as low fluid levels, cracked ducts, and clogged filters—can often be repaired with ease. Likewise, issues with your thermostat can be corrected readily. Whatever the problem, have your system inspected to determine the source of the problem.

  1. Has Your Energy Bill Increased?

Your energy bill should remain consistent aside from slight variations between seasons. If you notice your energy bill steadily increasing, you may have a broken or outdated system. If repairs or a replacement system fails to solve the problem, you may need to have your home inspected for air leaks.

  1. Have You Noticed Unusual Signs?

Older units often make unusual noises that should be inspected. Screeching and grinding, for instance, indicate that your system may need replacement.

Other unusual signs, including increased dust and humidity as well as strange odors, come from problems that can be repaired. Do not overlook these issues, however, as they may spring from a gas leak, burning wire, or something else serious. Better to take precautions than to deal with a broken-down HVAC system.

The Effects of Humid/Poor Indoor Air

Air Cleaner Installation, Blog, , , , , , , , ,

Some effects of highly humid and poor air quality are dizziness, fatigue, irritated lungs, nose, and throat; coughing, wheezing, and other cold and flu-like symptoms. Of course, there are more serious effects and illnesses that can occur over time if your poor air quality isn’t addressed in time. A good start would be to work with a quality air cleaning service to clear out your ventilation system in order to improve the quality of the air flowing through them.

Below, we discuss the effects humid and poor quality indoor air has on inhabitants and how we can help eliminate them: 

How Humid Air Can Affect Your Health

Humidity has several direct and indirect effects on indoor air quality, as well as on a person’s individual health over a long period of time. Firstly, a long period of humidity, combined with high temperatures, can cause the body to overheat, which could lead to heat exhaustion or heat stroke. This is because high humidity hinders the sweat from your body from properly evaporating so that your body temperature can cool down.

Additionally, humid environments support the growth of mold, mildew, and fungi, which can cause serious respiratory problems if left unaddressed for too long. High humidity keeps germs, bacteria, and other contaminants in the air longer than in dry air environments, making it easier for them to spread indoors. Excessive humidity can damage your family’s health, so make sure you hire an indoor air improvement expert to resolve it as soon as possible.  

How Poor Quality Indoor Air Can Affect Your Health

Poor-quality indoor air is produced from a wide variety of sources—both from within your home and outside of it. Some are natural pollutants, while others are the byproducts of chemicals and functioning appliances. Some influences on indoor air quality include: 

  • Cleaning supplies
  • Paint
  • Insect-repellent or insecticide products 
  • Cigarette smoke 
  • Carbon monoxide from heating elements (i.e. water heater or furnace)
  • Pet dander 
  • Radon

On the other hand, there are also a few outdoor influences on indoor air quality, such as: 

  • Remnant smoke from a burning fireplace 
  • Pollen 
  • Mold/Fungi spores 

All of these different sources, one way or another, enter your ventilation system and move through your home, gradually affecting you and your loved ones’ health over time. Some of these health effects can be minor, including:

  • Irritated throat, nose, and eyes
  • Headaches 
  • Fatigue 
  • Dizziness or light-headedness 

However, these effects can end up developing more serious conditions, such as: 

  • Asthma 
  • Heart disease 
  • Respiratory disease 
  • Cancer

All of these issues mentioned above have been found to have strong connections to spending extensive amounts of time in buildings and indoor spaces with poor indoor air quality. Thus, while its effects are subtle and gradual, maintaining healthy indoor air quality in your home is vital to the safety and wellness of you and your family.

HVAC Awareness: Parts & Their Lifespans

Blog, HVAC Inspection, , , , , , ,

Homeowners who have a malfunctioning HVAC system should research it and determine whether a professional HVAC repair or replacement offers better value. While the lifespan of any given part depends on its system’s type, daily usage, and maintenance, the industry has some general guidelines. For instance, compressors typically last between 10-15 years, furnaces 16-20 years, and window units 8-10 years (most models last 2-5 more years if maintained).

Below, we outline HVAC system types, parts, and their expected lifespans:

Air Conditioner Components

All home HVAC systems operate by exchanging interior and exterior air. The air conditioning function, in particular, is designed to pull warm air from inside and release it outside. It does so using the following parts: 

  • Evaporator – housed within the interior-facing portion of the unit, the evaporator cools indoor air using a copper tubing coil and aluminum fins.
  • Condenser – also made of a copper tubing coil, the exterior-facing condenser releases the unit’s collected heat outside.
     
  • Compressor – a pump that moves refrigerant fluid between the evaporator and condenser as well as their copper tubing.
  • Refrigerant fluid – a liquid pumped into the evaporator, where it pulls heat from the interior air by evaporating, to the condenser, where it releases heat and reverts back to a liquid.

Heating Components

In addition to their cooling capacities, many HVAC systems include heating functionality. Heating applies the air transfer principle, outlined above, in reverse: warm air is pulled from outside and released inside. However, when outdoor air becomes colder than the indoors, the HVAC system warms incoming air using one of two devices: 

  • Furnace – using natural gas, oil, or electricity, furnaces heat the air from outside then release it into ductwork that distributes it throughout a structure.
  • Boiler – instead of heating air, boilers heat water into steam that then warms the interior.

Heat pumps and geothermal heating systems are also used in homes, but they are far less common than furnaces and boilers.

The Lifespan of HVAC Systems & Parts

So, how long do all these systems (and their components) last? As mentioned above, the lifespan of each depends on its system’s daily usage and design. However, the following guidelines can give you a sense of their endurance: 

  • Central HVAC – the “traditional” form of heating and cooling, central HVAC systems combine heating, ventilation, and air conditioning (HVAC) functionalities. Each element of these systems has a different lifespan: furnaces tend to last 16-20 years while central air conditioners last 12-15. On the other hand, boilers last 10-15 years.
  • Air conditioning window units – estimates for window unit lifespans vary widely. Some sources place it at an average of 10 years while others 8 years. However, all agree that you can extend your unit’s life with regular maintenance.
  • Air conditioner parts – on top of unit lifespans, individual parts in air conditioners can fail. Compressors, for instance, last between 10-15 years. However, this means that you can replace a part without replacing the whole unit.
