High recommend AJ Heating & Air Conditioning! I called last summer with an emergency outage and they fit me in same day, did a fix to get me through season with suggestion for replacing before next season. Just finished the install on the replacement and did not disappoint! They are all so knowledgeable and friendly. Clean up after themselves and can really tell customer service is a priority. My replacement required moving a hot water heater and rerouting from attic to laundry room and they did it all quick and efficiently.

My furnace randomly went out the day after Xmas and AJ had a tech(Brian) out within hours and had us fixed up in no time. Brian was a great tech, super nice and very knowledgeable and had it running with ease. I cannot recommend this business more. Fast, trustworthy and reliable.

My a/c went out Saturday (one of the warmest days of the year so far). Alex showed up and promptly figured out that my thermostat wasn't working. He had pretty much the exact model on his truck and got it swapped out quickly and got me back in service. Thanks AJ Heating and Air-Conditioning for such awesome service!

I can’t say enough great things about AJ Heating and Cooling! Alex is wonderful to work with as well as Brian. Very knowledgeable and professional and this goes for everyone of his team members. You can tell they take pride in their work and really enjoy helping people. I hired them for a full New HVAC installation and all new ductwork. They did such an impressive job and I highly recommend AJ Heating and Cooling for any HVAC needs.

We've been using AJ Heating and Air Conditioning to service and maintain our two Carrier Heat Pumps. Brian, AJ's service tech, is very thorough and friendly. He explains everything he's doing and answers all our questions. We're signed up on their maintenance program to service our units twice a year. We appreciate Alex and all the folks at AJ Heating and Cooling for their excellent and friendly service.
