    "We have been using this excellent company for over 20 years and would highly recommend them. Our recent installation of a new Rheem furnace and AC reinforced our confidence in this excellent company. Though there were a few hiccups in the installation, I received the most courteous and concerned assistance one could hope for when purchasing and installing expensive and important equipment. Thank you for our new system! With a shout out to all those who went above and beyond: Troy, Jensen, Trystan, Keenan, Daran, Craig, A'lan, Brandon, Sol, Agnes, and everyone else that showed up. You were a great comfort and helped make this installment a success!"

They were professional, courteous, and took the time to explain to me just what they were doing, and to answer my questions. On a scale of one to ten they were both elevens. I'd give them six stars if I could. You can trust One Hour to do it right."

    "I had a great experience with Goodfellas. We purchased our home last year and the heating system had an issue recently. The company that installed the system came out and diagnosed all the issues as covered under warranty, so we would only have to pay for labor. The job would take around 2 hours and we were quoted nearly $1,000! After calling around, Goodfellas offered a fair price right from the beginning and was able to schedule the work within a couple of days. The technician was also helpful in explaining how our system works as it's non-standard for Colorado. All in all, Goodfellas was fantastic and I would recommend them highly."

    "I signed up 3 years ago to the Swan Club, which includes yearly inspections of our furnace, ac, and plumbing. Mark recently inspected our air conditioning system. After purchasing an HVAC system from Swan, we joined the Swan Club, which includes yearly inspections. Yesterday our service technician was Mark. He was extremely thorough and professional, and and walked us through the whole system with pictures and comments. He could not have been more helpful. Thanks Mark"

    "We received 5 quotes because an furnace and AC were really big ticket items for us, but the owner of this company took the time to explain every step and all the details of the work. Other contractors did not take the time to have a detailed discussion and even implied that we were not expert enough to understand the details. They were very quick to tell us what they thought we needed. There were 3 bids that were substantially lower so we were very nervous and second guessed our decision. They restored our faith in contractors as they went the extra mile to make sure that everything was the best quality and really thought about what they were doing and what the best solution(s) might be. They took our lifestyle into consideration and did not treat us as if we would not understand the process or care about the details. On this rare occasion we felt that we got the best for us and every penny was worth. We look forward to have this company service the HVAC that they installed for us. In additoin they took care of a few odd repairs that were needed at a very reasonable rate. We only wish we could find other trades for landscaping, remodeling, etc. like Vertical was for HVAC."

    "I've used Applewood Plumbing, Heating and Electric in the past and have never been disappointed. Preston came to perform a routine maintenance check on my furnace and noticed a problem with my water heater (potential carbon monoxide leak). He explained the issue and contacted one of their plumbers, sent pictures and, with my approval, arranged for immediate service. He then completed the inspection of my furnace and explained the inspection & the results and answered all of my questions. He was knowledgeable, courteous, and was able to explain things in a way a non-HVAC guy could understand."

    Apple Aire Logo
    Wheat Ridge, CO·

    "I spent a great deal of time with the owner on my property trying to find the most ideal cooling system for a split level, flat roof home with forced air heat. Location of the unit and capacity was particularly challenging for a mid-century home. When we were done we had the perfect cooling unit. During our conversation he saved us from certain disaster by noticing that our heat exchanger in the furnace was cracked (I had not done an inspection in quite some time). So, we purchased a new furnace and water heater at the same time. They do annual inspection on the air conditioner and furnace, and even remind us when it is time. The only problem we have had is the furnace manufacturer going out of business. Apple Aire still honors the warranty and works hard to make sure we have parts. And they come in the dead of night in the bitter winter if you need them. There is no one I would recommend more highly and no one I would rather do business with than Apple Aire."
