He checked why my gas tankless system was not putting out hot water. He was so friendly, so informative, just a really nice guy, found the problem right away and fixed it right away, and he gave my all sorts of tips on what to do about other problems I have been having with my old Patchogue house. I will only call them for now on and will recommend them to everyone for heating/HVAC. They were also reasonably priced. Thank you so much Taylor, and Donlon Bros., you guys were very good.

Highly recommend!

When I asked for ballpark, they said sounds like your 15 your-old system is too old to fix (coolant is no longer being used, so hard to re-charge system, etc. etc.), so could be $12-15k to replace. That's when I cold-called Action Air, just based on favorable Yelp rating and long time (9+) years in business. The woman I spoke to said they'd be there LATER THAT SAME DAY (Fri) and would keep me posted when he was in the nabe. I got a text at 4 pm saying tech on his way. David showed up within minutes. He was courteous, knowledgeable, efficient ... and honest. Made a quick circuit of our equipment (compressor, air handler, thermostat), and promptly determined it was just a thermostat issue. He went out to his truck and replaced the thermostat, explaining how it worked and giving us the user's manual from the box it came in. While there, he checked our air filters and the compressor, took a couple readings at the compressor and told us everything looked great, and that we should just hose out the grill around the outdoor compressor fan, noting that it was located close to a dryer vent so needed extra attention. Bottom line: This is just what. you want and need in a repair company, particularly when you're talking about equipment you may know very little about so could be at the mercy of dishonest vendors. Can't recommend Action (and David) highly enough. Saved me possibly thousands of $$$.

Big City came out and provided a clear diagnostic and estimate for each of the affected units. I was nervous about this being able to be fixed because of all the issues we'd been having but they were so kind and reassuring the whole way, which really made me feel like a solve was possible. And sure enough they did it! And my unit (and others in the building) are back up and running. They were so diligent and helpful getting everything restored, and were also such nice, wonderful, pleasant people. Thank you so much for all your kindness and help!!!
