I understand that this is a very busy season but not a call or email for just an appointment is not good. I do not understand why some companies even offer the option to fill in for a request on their web site. I filled out three other requests and with a day they provided me with an appointment. It's a shame because I liked the puppy sitting with the owner! Update on 07/1 I called again and this time I spoke with Christian who set up an appointment for 7/03 between 1-3pm.

Kyle is tremendous. Great AC, Great person, Great knowledge. We took 3 bids on a 25yr old Rheem…read moremachine. Two offered replacement. Kyle also offered a replacement but upon closer inspection said he could fix it. For an economical price. He had a new engine in his truck! First, he discovered the AC fuse had burned out in our box. He fixed that and then the AC unit. We were also building a new retaining wall the unit sat on. Two weeks later on 24 notice he came late Friday and moved the unit so the wall could be done in that corner. A week later, wall done, he came on Saturday morning and moved the unit back in place on the new wall. Bravo, Kyle! on 4th of July the old unit had a kink and needed some new wires to adjust the pressure. He put in new wires in Sunday morning 4th of July! This is caring service. This is a professional. He has EXTENSIVE AC knowledge. Kyle is also a personable trustworthy man. He tells good stories too. I highly recommend his services. The old 25yr old machine in is now in year 26 and works better than ever over the last 6 weeks. We are very happy. Thank you Kyle.

5 Stars - Honest, Quick, and Professional!…read more I had a great experience with this local HVAC company and highly recommend them. Our AC stopped working during the start of a heatwave, and Kyle was able to get out to us quickly. He was absolutely fantastic--friendly, professional, and incredibly knowledgeable. What really stood out was the honesty. Kyle diagnosed the issue fast, explained everything clearly, and made the repair without trying to upsell us on anything we didn't need. That kind of transparency and integrity is rare these days, and it's exactly why I'll be calling them again for any future HVAC needs. Thanks again to Kyle for the excellent service from start to finish!

Not only did they fix everything quickly and professionally, but they also put protections in place to make sure it doesn't happen again. They've also kept our 25-year-old central AC unit running like a champ, which is no small feat. Reliable, knowledgeable, and always responsive--this is the only call I make for any heating or AC questions. Highly recommend!

Gave the owner every opportunity to make it right but instead he just sent over priced offers to replace the system. Don't get me started on the inappropriate behavior of the tech at my house.

Provides a worthless written warranty that he (Steve) does not stand-by. They make plumbing mistakes and then cover up by saying that the matter was intentional and then wants more money to fix it.

Never did. but he automatically wanted to charge me $250 saying it was an oil issue. When I said how can you charge when you haven't even looked at it, it could be something that's covered under warranty. His response call someone else. I called someone else they came within two hours to find out it was the wrong nozzle and he never tested to calibrate the unit. In my opinion he just wants the initial lump sum but won't stand by his work. Beware
