We've heard what people say about other HVAC companies. We built Lou's to be the opposite.
"I can imagine if I had called one of the larger 'service provider' companies, I would have been informed I need a new unit. Thanks again for your honesty."
We diagnose what's actually wrong and fix it. If a $150 repair keeps your system running five more years, that's what we'll recommend. Period.
"He showed up first thing knowing that we were in for another 95 degree day."
We answer calls 24/7 and get to you quickly. When we arrive, we don't just fix it and leave. We explain what was wrong and how to prevent it in the future.
"Stuck to the original quoted price. Very friendly also."
We quote you a flat rate before we start any work. What we quote is what you pay. Free estimates, military discount available, no overtime charges sprung on you after the fact.

"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+"
"Lou was excellent! He patiently explained what was happening with our AC System and suggested the best path to get our AC up and running. He showed up first thing knowing that we were in for another 95 degree day. Very reasonable rate! I am glad to say we have found the right HVAC contractor for our home!"
"Honest, arrived on time and explained my issue with my AC unit in detail and his fees were very reasonable. I will always refer him to others."
"Lou did an efficient job of starting up my swamp cooler for the season. The water pump needed replacing and it was done quickly. The price was quite reasonable for the work done."
Meet Lou
Lou Hernandez has been working on HVAC systems in Denver since 2014. He started Lou's Heating & Cooling because he kept seeing homeowners get pushed into replacements they didn't need by companies that profit from upselling.
His approach is simple: figure out what's actually wrong, explain it clearly, fix it for a fair price. No mystery charges, no unnecessary repairs, no jargon.
