    Excellent service. David was very informative. He spent plenty of time doing my 6 month cleaning and maintenance. He checked things that never was looked at by other companies. Great job thanks David. Customer service from the call center was excellent also.

    Alltemp Air (Jason) provided impressive service repairing a Rinnai tankless hot water heater after our contracted provider failed to fix the intermittent issue on initial call and follow-up visit was delayed. Jason was able to analyze and isolate the issue, made temporary repairs so we had hot water consistently until parts arrived and installed within 2 days of initial call. We were so impressed with services from Alltemp Air that we are planning to transfer all of our HVAC and water heater support agreements.

    I can't say enough good things about AllTemp! I had heating issues and have used two different companies prior neither of which I would return to. I did some research and found AllTemp, I called on a Friday afternoon and Paris so was helpful and understanding - took my problem on board and gave me a sense of "what a great company" off the bat. My gut feel was not wrong, Jason turned up to try and resolve my issues, my heart kind of told me up front I think I need a new furnace, Paris was good enough to arrange for Jason to come out too around the same time to quote for a new unit just incase. Jason certainly gave it his best shot, but my appliance was not going to respond, it was done! Dylan helped me with options for a new furnace, with absolutely no pressure to make a decision. I made my choice and couldn't believe they could get me on the schedule for the next day! Sure enough Ken & Ray turned up right on time and worked all day, did the install, cleaned up and were even singing while they worked - their work might have been better than their singing but it was lovely to hear. I can't thank the whole team for what they did. Family owned, I love, attention to detail, I love, everyone I spoke to felt like one big family ... you guys are truly amazing, I recommend you in a heartbeat and I'm very particular about who I recommend!!!
