"Not very happy with them. They installed a new Lennox last year and sent up their "best" installers. They showed up late, left a huge mess both inside and outside of my house, but worst of all, they didn't bother to check the gas supply line. I didn't notice that there was a gas leak until the next day (a Saturday) and by then, my entire basement was full of gas fumes. I turned off the supply line and then called them and left an emergency message about the leak, but they didn't show up until the following Monday. When the new technician showed up on Monday, he was shocked at the shoddy workmanship that the techs and had to completely replace the supply line. He assured me that the two techs that did the installation were "chewed out" by their manager. One year later, I had a duct cleaning company come out and noticed that the exhaust pipe was screwed into plenum access, so now I have two holes in my plenum. Unfortunately, there are no other furnace contractors that will service Lennox furnaces up in the mountains, so I have to use their overpriced service to have my annual servicing. I'd think twice about using these guys for any new install."

"6-24-25 I originally gave Trey, a technician from One Source Home Service in Colorado Springs. CO, a 5 but now that has gone to a 0 and here is why. Trey did provide a maintenance service on the AC on 6-16-25 and also a service to clean the blower on the furnace on 6-20-25. But after he left Friday, I went to turn on the AC since it was 101 hot in Pueblo, the AC motor did not come on so my AC was not working. I called and texted Trey. Please note that Saturday it was going to be 103 in Pueblo. Trey said he will get someone over here. No one showed up on Friday, nor Saturday, nor Monday. Today is Tuesday 6-24-25. I still have not heard from Trey nor anyone else from One Source. I called One Source to speak to a manager or chief technician but no call back. We are in our 70's. This is no way to run a company. It does not appear that One Source has the customers interest in mind. The One Source web site states that “We agree to accept responsibility for your complete satisfaction with the materials we use and workmanship we provide.” Well we are not completely satisfied because Trey and One Source, in a sense, deserted us. Not Cool. I will attempt again to inform One Source about Trey’s actions and to ask to speak to his supervisor or manager of the company. My reviews of Trey’s work, his workmanship, and One Source will be posted on social media as well as Google Reviews, Angi, and others. As the saying goes, “Karma, I have a list of people you might have missed.” Be Careful with this company."
