"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"I am very happy with Dwyer and I highly recommend them. I am confident that I will be provided needed service. Having the semiannual maintenance plan keeps everything running right. They have been my company of choice for more than 8 years."

"Superb service by Relax Air!! I contacted Kamal for a second opinion after a different HVAC company quoted me a very large number for repair of capacitor and fan motor. My home in Ashburn is rented out and my tenants needed AC quickly. Kamal was extremely knowledgeable, polite, caring and professional. He came out the same day to repair the unit. His honesty is greatly appreciated. He discovered that there was nothing wrong with my fan motor (!!) and only my capacitor needed replacing. He cleaned and straightened the unit and saved me a very large sum of money. Great job Kamal, I would highly recommend your services to anyone. Thank you again."

"I had been told by a repairman from a company I had a service contract with that my furnace badly needed a cleaning and was quoted a price of $600 for the job as well as an additional $400 to remove a nonworking humidifier. These quotes seemed exorbitant and so I got some estimates, all much lower, and chose Dominion on the basis of reviews. Terrone said my furnace did not need a cleaning, passing up an opportunity to charge me for something I thought I needed, and repaired my humidifier for less than the cost the other company had quoted for merely removing it. He showed me what he was doing, explained how my heating system worked, and charged me a fair price for the job. I would certainly call Dominion again for any HVAC needs."

"They did a good job and eventually found a loose wire that fixed everything... But if the original prices quoted had been paid out I would have been pretty sad with their pricing. However, I only had to to pay out the agreed upon service fee and the well trained technician did an excellent job! The only reason this is not five stars is because they're quoted prices for refrigerant and other possible repairs were very high."

FAQs for central a/c service or repair projects in Alexandria, VA

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
