"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 needed a diagnostic test on my AC compressor in preparation for selling my home. Amar noted a slight leak on the capacitor that--while not critical--was an easy repair since he already had the unit open and the part in his truck. He took care of it quickly and efficiently and was very helpful in advising future owner maintenance. It is a shame I won't be able to use his services once I relocate!"

"Although the AC unit was working, it was leaking water. I had another company come in and tell me that the main drain pan was cracked and that it would cost $2880 to repair or I could buy a new unit costing over $8500 dollars. I called Relax Air for a second opinion. Kamal and his crew came out the next day and confirmed that the drain pan was cracked and leaking. His repair cost? $400. I also had him do two other HVAC related jobs while he was there (replacing AC disconnect box and installing a water float switch]. They had everything done in and hour and a half. Total cost: $675. Kamal is fast, efficient and most of all honest. I would recommend him to anyone."

"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."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"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."

"Technicians were on time and very courteous.  They thoroughly inspected and cleaned my 15 yr old air conditioner and changed my air filter as advertised.  Although they indicated that the system was nearing the end of its life due to high readings for volts, and strain on the motor, etc., they did not pressure me to unnecessarily replace parts at this time.  They did provide me with a few options for repairing or replacing the system in the future should it fail, all without the high pressure attempt to sell me more than I need at the moment (something I hate). I would definitely recommend both the company and technicians to others."

"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."

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.
