"John looked over the problem and said he could fix it! Great news to us. He was courteous and efficient and got the job done! And—He left everything clean. Planning to have him do another job for us."

"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."

"Definitely not reliable! Hired them to replace a lift pump in my house and less than a month after install it caught on fire and flooded our basement because a loose pipe was left in the pit and caused the motor to burn out. Second plumber came out and replaced pump but did not seal it. Now every time water runs through the pump the basement fills with sewage smell. Was told by third plumber nothing they could do. Management told me if the pump is working there is nothing they can do."

"I loved working with Pace and Sons for my HVAC needs. My furnace was leaking and actually required a bunch of replacement parts. Alec was super helpful and really knew his stuff. I really appreciated working with an hoenst pro who did good work and I'll definitely call them for my winter service."

"Nick from Colorado First Plumbing and Sewer did an amazing job on a stoppage in my kitchen sink! He was very professional and personable. He even gave me tips to keep the sink running smoothly. I mentioned an issue with a toilet running so he took a look and fixed in no time! I would HIGHLY recommend them for your plumbing needs!"

"I had almost the exact same experience as Derek. Charles came recommended by a radon company that was installing our radon system, and we hired him to address an issue with our hot water heater. The water heater problem turned out to be a simple blockage and vent issue, but we also hired Charles for a few other small projects around the house. Unfortunately, one of the simplest items he installed was done incorrectly. He even demonstrated a ?test? in front of us?clearly knowing it wasn?t properly installed?and since he did it right there, we didn?t think to double-check until after he left and we had already paid. Since then, Charles has bailed on us about four times after promising to come back and fix it. Before leaving, he also mentioned there was a one-year warranty on all his work, which now appears to be complete nonsense. At this point, he has stopped responding entirely, and we?ll have to hire another plumber to fix his mistakes. Do not recommend using Charles "
