"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!!!"

"They delivered what they promised! Mark Walker, sale manager for The Home Depot and McCrea, worked very hard to get our 2 new Carrier units, even though equipment in short supply. The McCrea installation team got our new units up and running beautifully. We are grateful to the dedication, and hard working of every body involved to get the job done right."

"ARS installed my A/C and furnace system about five years ago and they have been doing the maintenance and any repairs since then. The technicians are knowledgeable and professional. They do not try to sell unnecessary repairs or equipment."

"Had a great experience with Kamal. He is helpful, knowledgable and very dependable. We had a crisis with our old hvac system and were freezing. Kamal was the only one who came within 2 hours on a holiday while others were available only the next day or later. Most were closed that day. I got a great deal on the new SEER16 hvac and have been happy with it. My electric bill has cut down to almost half. Also he offers 2 years of his company’s warranty in addition to the manufacturers 10 year warranty. Highly recommend Kamal and will be using him for future."

"Going to take two visits, but that is because they wanted to see if when the unit thawed the fan was still working and save me over $1000. Turns out the fan is shot. So, calling them back, but I know they will be able to fix it. They have done work for me on this unit before. They cannot service all units, as I have a business and they weren't able to fix that one. But, they said that when they got there and looked at it before they spent a lot of time or money on parts, so at least they are honest."

"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."

"Very satisfied with responsiveness, punctuality and professionalism! Danny was able to squeeze us into Blue Star's full schedule at a time that worked for us and called before the visit for clarification about the problem, and after the visit about how things went. John called before arrival to let us know about exact timing, and was very thorough in investigating the problem and then explaining the situation. After consultation, he was able to repair our system. John also discussed what to look out for in case there are problems in the future. We have had our AC unit serviced regularly by other companies, but we will never use those other companies again. Blue Star is superior in every way! Cannot recommend highly enough. Thank you, Danny and John!!"

"Initially I was skeptical not knowing what to expect from SwiftPro because I had never used them before. They sure did surprise me with their professionalism and expertise in installing a new TRANE HVAC system in my home. Not only was the work excellent, but it was also done in a timely manner and to my full satisfaction. As an extra bonus, the new filtering system they put in actually helped in reducing my pollen allergies noticeably. Thank you Tyler, Moises, and Oscar for doing a top-notch job. If I ever need HVAC service again, i know who to call!!"

FAQs for central a/c service or repair projects in Ashburn, 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.
