Terry Taggart

Jon did a wonderful job repairing our evaporative cooler. He diagnosed the problem, over nighted the part, and repaired our unit in record time. We greatly appreciated his honest assessment and reliable repair. We would definitely us Jon and Allied Heating and Air again.

If you need repair, new equipment, or just have questions, Allied is the go-to HVAC company in the Denver Metro. They are simply one of the good companies around who actually provides quality service. They are technically knowledgeable, helpful, and good at what they do.

If you are unsure or wavering, rest assured, they will help you out. I will definitely use them again!

Allied came highly recommended from another company that couldn’t get to my house to fix my dead furnace on the coldest day of the year. Their call center folks were very pleasant and had a technician to my house within the hour. The tech was very knowledgeable and had my furnace up and running within 2 hrs. I will use them again.

In the fall, we had got a bid to move our air conditioner from our deck over to the side of our house, and it was almost $7000! There was no way we could afford to do that, so we resigned ourselves to talking over our loud air conditioner in the summer months. However, Allied came out to bid the project, and came in more than $5,000 less!

The guys were out yesterday, and I couldn’t be more pleased. They were to my house at the beginning of the time window (not waiting around for them to show up). The technicians were very knowledgeable, and checked in with me if they ran into any issues (there were a couple) before continuing. My air conditioner is running better than it ever has as they cleaned all the gunk out that had collected over the years, and now I can sit on my back deck and have a normal sound level conversation! I will use them again, and recommend anyone to do the same.

Awesome customer service and Ed was a great furnace technician. Answered all my questions and put me at ease. I would use Allied again and refer to friends.

Very quick response, even on a weekend. Their work was very professional and honest. They covered my issue under warranty, even though the warranty had expired.

I contacted Allied today because my furnace stopped working last night. I called the office at 8:00am and the front desk person was extremely friendly and told me that they were pretty busy but would try to get me in. She called back 10 minutes later and said that she moved some “non-emergency” calls around so she could get a tech to my house asap. The tech showed up 20 minutes later and fixed my problem. I would highly recommend this company for not only their speedy response but for actually caring about my family and doing everything they could to make sure we had heat!

I’ve used Allied for a number of my HVAC needs, from the yearly furnace tune up to a full scale blower motor replacement. The receptionist staff is always very friendly and doesn’t transfer you to three techs to answer your question.

The service guys have all been on time (or early, which is awesome) and are considerate about wiping their feet, not touching the walls and in their post-work cleaning. Never had so much as a scrap left on the floor.

Their prices are a bit high, but I’d rather pay for good work and good service.
