"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"In preparation for replacing my HVAC system, I went through a few different estimates. The reason I chose Air-Tech was not because of price, but because I was impressed by the details provided to me. Rod was great. We went into the attic, reviewed all the components inside and out. And we discussed the scope of the work. Once I agreed, he gave me a start date\time. The crew showed up on time and worked hard for two days. Not only was I comfortable with Rod, but the crew was great. My new system is in place and I couldn’t be happier that I chose Air-Tech. If you’re in the market for a new HVAC system, do yourself a favor and call them. You won’t be disappointed."

"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."
