McAllister has done work for us multiple times, and we always receive excellent service. We have an old gas boiler heating system and had a pipe burst. Needless to say, we were anxious about it. Jeff came out, diagnosed, and fixed the problem on very short notice. Professional service at a reasonable price. What a huge…

McAllister just recently installed all new heating and cooling systems in our home and rental property. From the first interaction with the sales rep to the men that did the installation, everyone was professional, kind, and very easy to work with. We have had many updates and things done to our home recently, and I never…

We called about our heat going out, and they sent a tech out within a half hour. Unfortunately for us, we needed a whole new furnace. They were able to have a team out the next day to install the system! The techs were all very polite and efficient! They offer many payment options, which was…

McAllister was great to work with. Great communication, affordable financing, and they did a great job installing. I'm happy with the AC mini-split that was installed and am glad I chose them for the work. Thanks again!

They have replaced both our water heaters, installed a new AC unit, and some smaller plumbing issues. They are very friendly to work with, always manage to schedule us promptly, and do excellent…

Simply the best! We have used McAllister since we moved six years ago, and they have always been professional, responsive, and accommodating. Quality costs, but you get what you pay for. And it's worth it to us when, at 8pm on a Friday night, a professional will come out and do their best to get our…

I was away from my home from 8:00 am until 10:00 pm. When I got home, I heard water running. The pipe under my sink burst and flooded my bathroom, hallway, and basement. I called McAllister as I know they have an emergency number. A very nice gentleman was at my home within the hour. He…

My hot water heater exhaust chimney was blocked. The gas company showed me the carbon monoxide reading and shut it down. The guys from McAllister showed up promptly, figured out the problem without much fuss, fixed that hot water heater, AND another hot water heater that had been shut down long ago, probably for the same…
