Trane Furnace
I have a several years old system that has been underperforming since installation. Based on positive reviews I had seen on social media, I asked MyGuyHeatingandAir (Leonard Wilson) to review it. Leonard exceded my expectations, was able to understand technical details of my system without having seen it just from my description and also even though the unit is not made by the manufacturer that he says he prefers. He nonetheless knew the electronics and flow/pressures off the top of his head, for this less-preferred system!

He quickly determined the scope of the problem, the range of possible fixes and costs, and was able to achieve success with the lower cost (and time) solution. He is personable and eager to demonstrate technical issues in a simple way, to clarify what the repairs entail.

When I have Driveway Drinks with my neighborhood friends ... comparing notes on HVAC issues, MyGuyHeatingAndAir.com gets my highest recommendation.


Lafayette, CO

Leonard is exceptional! He was referred to us by friends, and delivered in every way. He arrived on time, fully diagnosed our HVAC issues, and comprehensively outlined our repair options. He was completely honest, and never once tried to upsell us on any products; in fact, he did just the opposite. He is extremely professional. I highly recommend him!

I’m so impressed and thankful for Leonard! He’s honest, and his pricing is the BEST out there. He was able to figure out what is wrong with our furnace and fixed it! He made sure our system was nice and clean before he left. Very impressed, I would highly recommend him!
