A new furnace is a big decision, and the right install makes all the difference in how warm, quiet, and efficient your Sterling home stays for years to come. R.A. Dobson has been replacing furnaces across Northern Virginia since 1975, and we take the time to size your system correctly and install it to the manufacturer specifications — so it runs the way it should from day one.
As a Carrier Factory Authorized Dealer, we help you choose equipment that fits your home and your budget, then back it with our own one-year service warranty on top of the manufacturer coverage.
A furnace installed correctly does more than heat — it lowers your bills, runs quietly, and lasts longer. Here is what our process covers:
• A load calculation to size the furnace to your home, not a rule of thumb
• Honest guidance on efficiency and the right AFUE rating for your needs
• A range of Carrier equipment, from reliable standard models to high-efficiency systems
• Safe removal and disposal of your old furnace
• Proper gas, venting, and electrical connections
• A full startup test to confirm safe, even heating
• Financing available through Wells Fargo to spread out the cost
Understanding AFUE. AFUE, or Annual Fuel Utilization Efficiency, tells you how much of your fuel becomes heat. An older furnace might run at 70 percent, while a modern high-efficiency unit can reach 96 percent or more — meaning less waste and a lower monthly bill through those long Northern Virginia winters. We will show you the trade-off between upfront cost and long-term savings so you can choose with confidence.
A few common questions. How long does an install take? Most furnace replacements are done in a single day. Do you offer financing? Yes — flexible financing is available through Wells Fargo. What if my furnace still runs but is on its last legs? Compare notes on our furnace repair page, and we will give you a straight answer on repair versus replacement.
