Gas Fireplace Replacement in Longmont, CO 80504

“The Tech arrived on time. I would give a 5 star rating if he was able to 100% diagnose the problem. He guessed the same thing that I did, but said he wasn't completely sure. He completed the work that I asked for and did so efficiently and quickly.”

Gas Fireplace Maintenance in Erie, CO 80026

“I mentioned during my initial call that it was not a rush and yet you were able to provide service the same day as my call. That was great. The service technician arrived on time. Was courteous, thorough and kept me informed.
The part was ordered and installed again within the window ( 1hr) of time that you indicated it would be. Very satisfied.
I did not do any price comparisons.. so I am not sure about the price I paid as compared to industry average.
I am a very satisfied customer.”
