"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

"This company was without question one of the best we have worked with. Polite, honest about the work to be done and the time frame to get it done. Our Navien boiler/heat combo went on the fritz during a major cold snap and the holidays, a double whammy. They came out that very day. Jared was our technician, he was awesome. Kelley's was able to get the needed part to fix the issue the next day. He came back not only fixed the problem, but waited for 30 minutes before departure checking the system and making certain everything was running as designed. Since the combo system went down during such extreme cold days, extra pressure built up that didn't present itself until the next day. We texted Jared, he not only responded to the text, he called us immediately, on a Sunday and walked us through what turned out to be a simple fix. Things have been running smoothly ever since. Jared was awesome. This is our families team FOREVER!"
