"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."

"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."

"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."

"September 2019, my water heater broke and TC HVAC Services replaced it with a new water heater. And they also fixed my AC and fridge. Recently, in October 2019, TC HVAC Services installed a new humidifier in my home. Mr. Thea Chea, the specialist was professional, honest, and he answered all of my questions. The repairs and installation were completed in a timely manner. And costs were reasonable and fair. I would definitely use TC HVAC Services again and I have recommended TC HVAC Services to my family and friends. Thank you, Mr. Chea and TC HVAC Services LLC."

"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."

"Timely, professional, and personable technician. Provided options for repairs and coordinated an assessment for replacement of system. I’m a customer that was moved with the sale of A-One to John C Flood and I am happy with the transition. The work was on my HVAC system, but that was not listed in the drop down."

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.
