“I had a scheduled appointment with Dean of One Hour Heating and AC. He arrived on time and went to work. He discovered the outdoor AC unit had not been wired to my house for electricity. I was fortunate that Dean was allowed to do some installation jobs such as wiring up a unit into the home's electricity. I have a very old house (120 years old) but the AC had been modernized to breakers from fuses. Unfortunately the needed breaker was not a common one. Dean went looking for it in town and found one. He got everything working and gave me a quick tutorial on my touch screen thermostat to top it all off. He was excellent and informative and easy to work with. Definitely a 10 out of 10!”

“Jasmine was very thorough, polite, and professional with the maintenance checks of our furnace. She provided options to restore our furnace closer to its' original efficiency. She conducted a detailed evaluation of our home to determine furnace and our 10 year old air conditioning replacement options. After she completely explained all of the purchasing options she provided a quote with discounts. She answered all of my questions and gave me plenty of time to make a decision. I decided to purchase a new furnace and air conditioning system. Jasmine arranged to have these installed within 2 days!!! This is why I am a long time customer of One Hour Heating & Air Conditioning.”

“The crew thar was sent to my home was polite, professional & efficient. They arrived early & completed the work in a timely manner. We are very satisfied & would definitely recommend One hour to others! Shout out to Ivan for his honesty & professionalism. He completed all the maintenance on our furnace & he did all the work necessary & cleaned everything that was required. in the past, other techs had not done the work they were supposed to yet, ensured us they did. I'm pleased that the company is hiring workers like him & getting rid of the ones who are dishonest!”

“I want to give a big thank you to Brody Sheridan. He was awesome. He had to come out multiple times because we had multiple issues on an old heater- and he was absolutely fantastic. His attitude, high level of Customer Service, and willingness to go the extra mile was the best experience I’ve had since moving to Colorado. I want to say that in will definitely be using you guys again and requesting Brody for any issues we may have. He as absolutely the best and you now have a customer for life because of him.”

“I contacted Benjamin Franklin Plumbing last night and they sent Cristi out this morning to determine why I had water dripping under my kitchen sink. Cristi assessed the situation and found the problem right away. He immediately gave me the fix and cost. I asked him to look at a couple other things and he again gave me the fix and cost. I asked him to complete some of my issues and will plan another visit for the remainder. He also gave me my once a year plumbing inspection that I receive as part of my membership. Cristi has been at my home before and he is very knowledgeable and he gets right to the point but is very friendly. He is kind, quiet and confident. Thanks, Cristi!”
