"The best customer service I ve experienced. Immediate telephone response (during a 3-day weekend) and Albert arrived within an hour, diagnosed the problem quickly, made the repair and thanked me for my business. Cost is fair and service is outstanding. Definitely my new HVAC guy, period. Highly recommend you call Magna Tech (Albert) for any HVAC issues."

"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."

"Very well. Technician, John, was patient and thorough as he cleaned and took readings of the systems. He took the time to walk me through the maintenance and care that I need to take care of the Heating and water heater systems of my newly acquired condo in Fairfax County Virginia."

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