What Denver homeowners say about Lou's Heating & Cooling.

"If I could I would give at least 10 stars. I have a Breezair system that is starting to show its age. I had read reviews from others about nightmares with the electronics going out on them. I was prepared to face an enormous bill based on what I'd seen. Lou and his partner came out, did a thorough cleaning of the unit and had it up and running in no time. I asked what the issue was with the unit and was informed it was just a loose connection. What a refreshing relief to find someone so honest. Stuck to the original quoted price. Very friendly also. I can imagine if I had called one of the larger "service provider" companies, I would have been informed I need a new unit. Would recommend this company for any of your HVAC needs. Thanks again for your honesty."

"Lou was among the most pleasant and professional tradesman and individual I have ever hired. He did exactly what he said he would do and when he said he would do it, even going above and beyond expectations, which is a high bar. I give Lou my highest recommendation."

"Not only was Lou prompt and meticulous, but he also educated me on how the AC system works and the best way going forward to get the most out of my system. A+"
