"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."

"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 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."

"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."

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"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 Dulles, 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.
