If I could give John more than 5 stars, I would. One of my central ac units bombed out on one of…read morethe hottest days. He squeezed me in the same day. He said he was coming at 5, then was running late but communicated he would still be there as soon as he could. This man came at 930 at night--when most people would've already been home in bed, and said I'm going to keep my word and I told you I would come so if it's still okay and not too late I'm 10 mins away.... He showed up; Diagnosed everything, gave us a temp fix overnight, sent me a quote (since we needed a new system), then called me the next morning to tell me he found the equipment for slightly less and got me an even lower price! And is replacing the unit the next day. Wow... aside from being super professional, he was honest and very knowledgeable. I had two other quotes done out of due diligence (which I do for every big job or contract work), and he also gave us the best pricing. So I would highly, highly recommend John and his company. And I'm so glad we found him. We will definitely be using him for any HvAC needs going forward.

Needed a whole new hybrid unit, inside and outside. John was exceptional. The old unit left in the…read morecondo was horrible and there were so many things wrong that we didn't realize until it finally stopped working. John, James and Kyle went above and beyond the original scope of the work to do a proper install. Needless to say we now have an amazing unit done correctly. He and his crew are meticulous, neat (cleanup looks like no one was working there) and his recommendations were spot on. A real pleasure to have found him. Hopefully I won't need his services in the future but if I do he'll be my first call. Thanks again.

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!

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.
