"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."

"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."

"Although they provide a time frame for service, frequently they are late or have to re-schedule. When ARS installed my furnace, they provided a humidifier as well. However, the humidifier is not included in the maintenance contract, and any work or filter change on the humidifier is extra. The cost is almost as much as the maintenance contract. They used to answer the phone asking how they could provide exceptional service. No longer do they ask that. Makes sense, because they do not provide exceptional service. Also, the technician seems to want to convince you to buy additional equipment, which may or may not be needed."

"I recently had the pleasure of experiencing the exceptional service provided by Air Quality HVAC LLC, specifically their technician Jay Vardhan. In the midst of a chilly evening with temperatures plummeting into the 30s, my nearly 20-year-old Lennox HVAC system decided to stop heating. Having dealt with major HVAC service companies in the past, where the experience often felt like a battle of wits against deceptive practices, I approached this situation with a sense of trepidation. Upon the recommendation of a neighbor, I decided to reach out to Amar from Air Quality HVAC LLC. To my relief, Jay Vardhan was dispatched to my home within an hour, accompanied by a reasonable service fee. From the moment Jay stepped into my home, it was evident that he was not your average technician. Jay's professionalism, technical competence, and, above all, his honesty, set him apart from the rest. Unlike previous encounters with other companies, Jay took the time to methodically run checks on my HVAC system, explaining each step of the process with clarity and patience. His knowledge was not only evident but also accompanied by a genuine desire to educate and inform rather than exploit. What truly stood out was Jay's honesty and transparency. He provided insights into potential issues and presented a range of options without any hint of upselling or deceit. It was like having a conversation with a trusted friend or family member who genuinely had your best interests at heart. The issue with my HVAC system turned out to be a tripped limit switch, and Jay, with his commendable patience, navigated the challenging design of the Lennox system to reset it and restore functionality. The level of dedication and commitment displayed by Jay was truly commendable. I would like to express my sincere gratitude to Jay Vardhan and Amar from Air Quality HVAC LLC for providing a service that goes beyond the norm. In an industry where honesty and integrity have become rare commodities, encountering professionals like Jay is a refreshing and reassuring experience. The work was done efficiently, and my trust in HVAC technicians has been restored. I wholeheartedly recommend Air Quality HVAC LLC for their exceptional service and commitment to honesty in an industry where it is often lacking."

"T was great! We called him and within the hour he was at our house already. Provided us some options on how we can repair AC unit. Explained the problem and offer us multiple solutions. Not very pushy, very professional. Would highly recommend to other customer needing same type of service."

"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."

"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."

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