Allied Heating & Air Conditioning is truly an exceptional company. My satisfaction level with their service and my new heater is at an all-time high. Their expertise in the field is evident in their work. I had an old, troublesome heater that needed replacement, and the ductwork was giving me a lot of issues. The team, however, took their time to understand every aspect of the problem and optimized my system effectively. Brendan was able to explain everything to me in a way that was easy to understand, and his depth of knowledge surpassed any that I've encountered with other heater repair services. Notably, when I inquired about pricier models, I was advised that they wouldn't be suitable for my residence in Denver. This level of honesty is refreshing. I can't recommend them highly enough.

Allied Heating & Air Conditioning did a fantastic job helping me with an issue I had under my A/C condenser. They sent someone out to fix the support structures under warranty. I’ve always been happy with their sales process, HVAC installation, regular maintenance, and how they handle warranty repairs. After a recent storm, my air conditioner was still running but the iComfort thermostat screen went dark. I called for help on a Saturday, and they quickly called me back and scheduled a service visit for Monday. By then, my A/C had completely stopped working. Matthew was the technician who came out. He diagnosed the problem, and although he didn’t have the replacement part on hand, he found one, picked it up, and came back to install a new thermostat. He got my HVAC system cooling again and even helped me set up the iComfort app on my phone. Matthew was very professional, knowledgeable, and did great repair work. I was a bit nervous about getting the system fixed, but he made sure everything was taken care of. I’ve been a satisfied customer for many years and really appreciate their support. I highly recommend them for any heating and air conditioning needs. If you ask for Matthew on your next service call, you’ll be glad you did.

Late Friday, our AC suddenly stopped working. We called Allied Heating & Air Conditioning right away. About an hour later, Ross showed up to check out the problem. Early Saturday, he gave us different options, explained everything clearly, and went over pricing. By Monday morning, Brendan arrived at 9am, and just five hours later, our new HVAC system was running and blowing nice, cold air! Brendan patiently answered all my questions while working. The only reason it took more than 24 hours was because our AC broke late on a Friday. We’re so grateful for the fast response, great service, fair pricing, and positive attitude. Can’t beat this team! Now our house in Denver is cool and comfortable again.
