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.

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!

This is by far the BIGGEST RIP-OFF in the Hamptons. Under the guise of professionalism, the…read moremanager, Steve Cummings, demonstrates a flagrant disregard for honesty and integrity, making him nothing short of a scammer. Engaging with this company is akin to willingly subjecting oneself to notoriously getting "Hamped" (overpaying because you live here). Steve brazenly alters contract terms midstream, leading to exorbitant unexpected charges. Call is company if you wish to drastically overpay for plumbing or HVAC services. Their lack of internal communication between the HVAC and plumbing divisions is appalling. Their work ethic is marred by a series of blunders, which they subsequently exploit by overcharging to rectify their own mistakes. Initial promises are deceitfully simplistic, only to be arbitrarily amended once the fifty percent deposit is paid before the work begins. Look at your proposal and agreement closely because they intentionally leave out details they previously claim will be included in the price. There is no benefit to being loyal to this company and no price break for being a long time customer. I would rather drown in my house than call this company to fix a leak. FYI - this company is the same owner as Order-A-Plumber BE WARNED! STEER CLEAR!
