Best Heating & Air Conditioning / HVAC In Chantilly

“Complete gentleman tech showed up on time with a call ahead. Efficient and patiently answered questions.“

“Payam was prompt and professional. He was very knowledgeable and took the time to explain the issue with a sensor that needed to be replaced. He had the part on hand and was able to make the fix in about an hour. The same day service was much appreciated. Highly recommend.“

“Phillip was very honest and competent. He has a great personality, and arrived at the expected time.“

“Sean Hoffman did it again. Air One Tech is lucky to have him on board. Sean was able to troubleshoot the issue with the Aprilaire humidistat that makes clicking noise when it is running. He traced the issue back to the wiring from the humidistat that attempts to get sufficient power from the furnace control switch. If it is not for Sean, I might be asked by another technician to replace the humidistat and or the humidifier solenoid valve. There is a lesson learned here. When the HVAC system was installed in the Summer, there are undetected issues with all the wiring connected to various components that made up the HVAC system (thermostat, AC unit, central humidifier, furnace, and coil unit). Problems raise to the surface when cold weather starts. Even with a QA inspection followed up right after the installation of a new system, the technician couldn’t visually spot any potential misconnected wires until it actually happens. So with that, thank you Sean for doing a great job diagnosing the problem.“

“Mann-In did a great job when we replaced our heat pump a few years ago! I'm posting now because they just saved my parents from replacing their system when they were told by another company their heat pump couldn't be fixed. Mann-In did an evaluation and saved my parents $13k for a replacement they didn't need. Thank goodness there are still some honest companies like Mann-In!! Thank you!“

“If you want competence and knowledge, call Alpha Aire. 24 degrees outside with no heat. Scott had it working in record time. He came highly recommended ~ I highly recommend him to you. I am ashamed to say I rarely take the time to write reviews. This man deserves 5+ stars!!!“

“They got the job done. It took them 3 trips, but it was a warranty repair so I was ok with that. The techs were professional and knowledgeable. One star taken away because when I talked to the scheduler, about the issue with my attic furnace, I told him that it appeared the ignitor was bad and I gave him the furnace make and model number and requested he pass the info to the tech coming to repair the furnace so he has the correct ignitor. He assured me they have plenty of ignitors. Well, you can guess what happened... yup, he did not have the correct ignitor. That required 2 more nights without heat in the upstairs. Another tech came, replaced the ignitor and discovered that the circuit board was also bad, which required another day to get the new board and they installed it the next day. Rick was great and got the job done. I would call them again to work on my equipment.“

“The service provided by Emanuel Trejo, KP Pham and the front office staff was extremely professional and helpful throughout the entire process.“

“Our HVAC system was serviced on the rescheduled date and time. They service tech was professional and gave use suggestions on ensuring we change the filters more often. Hopefully the office when sending jobs to technicians will stop putting last minute jobs on the schedule. Remember that people have to take a half day off of work when they have a scheduled appointment with you, so if you cancel on them for an Emergency job your customer has lost 1/2 days pay.“

“I cannot recommend Hava Tech highly enough. They do awesome work, staff is all very professional, punctual, and their work is very well done, efficient, and buttoned up. Incredible value, money well spent! So glad we use them for our warehouse mechanical / HVAC definitely the right team for the job.“
