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!
