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 Consider the benefits of a new heat pump installation when your outdated unit costs you a fortune.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.

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.

Below, we outline the benefits of humidifiers and the Aprilaire 800 system:

Humidifier System Types and Benefits

Although several home remedies can increase a building’s indoor humidity, mechanical humidifiers are designed to perform this specific task. Several different technologies can achieve this goal, but the most common kinds of humidifier systems are steam, impeller, ultrasonic, and wick.

Although each system comes with pros and cons, the benefits of humidifiers include:

  • Preventing respiratory illnesses like influenza
  • Easing coughs
  • Reducing snoring
  • Moistening building occupants’ skin and hair
  • Invigorating materials (and plants!) within a building

The Aprilaire 800 Residential Steam Humidifier

Humidifier Repair Ashburn VA

As its name suggests, the Aprilaire system operates using steam. It needs only simple upkeep: replace the machine’s canister—which contains electrodes that heat the water—with a new one at the end of peak usage season. That said, system repairs require a professional due to the Aprilaire’s delicate technology.

This humidifier can cover up to 5,200 square feet in an average interior. It works best in dry climates as well as those that undergo mild winters. The water it uses need not be purified; indeed, water impurities help transfer electrical charges.

Aprilaire 800 comes with digital, easy-to-use controls. Its dual sensor automatic setting tracks both outdoor temperature and indoor relative humidity to determine the optimal level for an individual structure. Finally, it aims to set an indoor humidity level between 40% – 60%, which curtails bacterial and fungal formation as well as allergy and asthma symptoms.

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.

If you are in need of a better heating, cooling, or plumbing system, talk to us at RA Dobson. 

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. 

What RA Dobson Can Do to Help

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).

For all your HVAC questions, repairs, and installations, reach out to RA Dobson. We are the Ashburn, VA, region’s provider of heating, cooling, and plumbing services.

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.

A Guide To Your HVAC System

Blog, HVAC Inspection, , , , ,

“HVAC” stands for heating, ventilation, and air conditioning, and an HVAC system is what heats and cools your home. During cold seasons, you rely on the furnace portion of your HVAC system. And during warmer months, you rely on the AC. But to keep both systems running, invest in a professional HVAC inspection service that checks all their basic parts.

Below, we explore the 8 basic parts of a typical HVAC system:

1. Thermostat

You can think of the thermostat as the “brain” of your HVAC system. It contains a thermometer that gauges the system’s running temperature against your home’s interior temperature. To match the two, the system turns on the furnace or air conditioner so that your home reaches the desired temperature.

2. Furnace and Blower Motor

Next is the furnace, a relatively large unit distinct from the AC that demands its own space in the basement, attic, or closet. A fuel source – such as natural gas, oil, or electricity – heats the air that comes into it. Then, an attached blower motor distributes the air through ducts to the rest of the house. The motor also pulls in cool air from the house to start the process over again.

3. Heat Exchanger

A heat exchanger is a device that transfers heat from one medium to another. If your furnace uses oil or gas, burners accomplish the heating. If it runs on electricity, electric coils heat the air. As the heat exchanger warms up the air, heat transfers to the metal walls. The air heats up quickly and then is distributed throughout the home. 

4. Evaporator Coil

An evaporator coil is the internal portion of a split-system air conditioner. It absorbs heat from the air in your house so that only cool air remains.

5. Condensing Unit

The condensing unit is a big metal unit that sits outside your house and expels the heat from the interior to the exterior.

6. Refrigerant Lines

Refrigerant lines make air conditioning possible. Made of copper and aluminum, and run between the condensing unit and evaporator coil. They are responsible for carrying the refrigerant between the condensing unit and the evaporator coil.

7. Ductwork

Ductwork includes all the metal passages that deliver and move the air. They should be sealed and insulated to prevent major temperature shifts. 

8. Return and Supply Registers

These are covers that fit over the ductwork ends. They allow air out of and into the HVAC system. They are typically located on the ceiling, walls, and floors depending on the ductwork layout.
