Water Heater Repair in Lafayette, CO 80023
“Controlling Systems installed a tankless water heater in our home a year ago. We have loved this unit but we started having a few issues. Bailey came over to diagnose the problem. He was able to identify that it was due to a manufacturer’s defect. He worked with the manufacturer and was able to get the part overnighted. He returned to our home the next day and fixed the issue. Bailey was friendly, respectful, professional and skilled in his craft. He also made sure to protect our floors as he came in and out of the house and cleaned up any mess made during the repair. I would highly recommend Controlling Systems for all your HVAC needs!”
I would highly recommend this company.
Two installers were sent the day of installation. They were both courteous and professional! They arrived on time and immediately dismantled the old system and prepared the space for the new system! They were very efficient and worked well together as a team. Following the completion of their work, they ran the furnace and explained the functions of the thermostat in great detail!
I want to thank both Gemini and Roman for their attention to detail, answering our endless questions, and removing all remnants of their work! I would highly recommend this company and these two employees!

“An HVAC company that does what they promise, in reasonable time, for market-reasonable cost? With pleasant humans throughout the process?? Unheard of. Until I hired Controlling Systems to replace my 14-year buggy radiant home heating and on-demand hot water system. Seven of the contractors who looked at my mess earned a spot on the spreadsheet comparing contenders. Some said stupid salesy-desperate things like, “ours is the only high-efficiency unit on the market,” and, “only ours is the top model.” Ich. Bailey’s deep knowledge and clear, straightforward communication earned my trust, and then he followed through! Over the years I’ve paid a LOT of HVAC guys to not fix the prior system, or clearly recommend actual replacement options, featuring the outcomes I could expect, especially concerning heating the cold spots in the house. What a breath of fresh (warm!) air: with Gus’ smiling assistance, Bailey expertly installed a new unit, which runs economically, quietly, and I can trust, reliably for many years to come. 10 stars!”
