AAirtech was the original installer of my entire HVAC system in my newly renovated home. After installation, I had hired AAirtech to an annual maintenance contract to do spring/fall start-up/maintenance on my HVAC unit. This spring, they contacted me to arrange a time, and as my schedule is busy they were unable to find a time before 8am or after 6pm on any day of the week to perform the annual startup. While waiting for them to find a time, my AC died. Of course, during a heat wave. I contacted AAirtech and they were remarkably unhelpful considering I had a current maintenance contract. I asked for an on-call visit to fix the AC and they said it would be 3-4 days until they could come. I suggested that this was unacceptable as they had not bothered to perform the annual maintenance I was contracted to receive nearly a month previously (which likely led to the HVAC failure). I spoke with a number of people and eventually was told by the 'business owner' that they didn't want my business and they would be refunding my maintenance contract fee.
Do not expect decent customer service from this company. Do not expect that they will honor their contracts. If you request they do honor the contract, they will cancel the contract if it is inconvienient for them. They don't mind if you pay them if they don't have to do any work, but the moment you require urgent service, they will make themselves scarce.
Avoid. This. Company.
