I first contacted this company back in September for an oil tank issue, & the experience was so…read moregood that I've called them multiple times since. We had an urgent situation & I reached out on a Sunday after checking their website & pricing. Steven & Jill are fantastic. He clearly explained what was wrong with our oil tank, walked me through how he would fix it & communicated throughout the entire process. I never felt pressured, just informed & confident in the decisions being made. He got our hot water back quickly, then installed a new oil tank, handled the wiring & cleaned up thoroughly before leaving. They're professional, friendly & easy to work with. Since that first visit, I've contacted them twice for other issues & each time they've been honest, responsive & reliable. Their pricing is fair & absolutely worth it for the quality of work & peace of mind. I wouldn't hesitate to call them again & highly recommend them.

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.

Terrible Company. I hired M&M to replace a corroded pipe to my boiler. As a result of their…read moreincompetent work my house was left without heat. The Owner Max has refused to come fix the issue. After paying $500 to him, He wants to charge us again to fix the issue that his company left us. We had heat in our home before the repair. After workers from M&M Precision Plumbing came to our home we have no heat. The repair cost us $500 and the owner Max wants to charge us more money to come fix the issue that his company caused. We have had other Plumbing companies inspect our issue to determine the cause was a Direct result of M&M not bleeding my valves properly leaving my pipes air locked. Max (the owner) was supposed to come fix this issue over a weekend, but has ignored phone calls and never showed up to our house. This is a terrible company with terrible customer service. Save your money and look for a more reliable company that you won't need to take to Small Claims Court!

I did a major basement renovation last summer and my contractor used this company to upgrade my…read moreentire service. I went from one zone of central air and converted it to 2 zones with ac and heat. To say it has been a disaster has been an understatement. When they put the new system in I told them of a particular room that didn't stay as cool as the rest of the house. They said they would make sure to take care of it. Well the new system actually works worse than my 20 year old single zone system. A few highlights On one hot day the thermostat upstairs is set at 68. My sons room is well over 73 degrees The hot room that was a problem is 74-75 degrees on hot days even though my thermostat is set at 68. The basement renovation they decided to put only one vent all the way on the back by the Bilco door. In the winter the basement is 61 degrees while the thermostat is set at 70 on the first floor. They had to come out here 4 times before they realized they wired the system incorrectly when they installed it I don't expect exact temperature match with the thermostats in every room. But when I drop 40k plus a new system it should be pretty damn close. They often send guys out and say they will come back or talk to the owner about the problem. They never do. Stay far away

The technicians were knowledgeable and worked efficiently to get the job done in a timely fashion. They made sure everything was clean and in perfect working order before they left. The quality of their work truly shows, and they went above and beyond to make sure I was a satisfied customer. If your looking for a reliable, honest, and skilled HVAC company than I highly recommend them. I will definitely be using them again for any future heating or cooling needs. Thank you for a job well done!! Susan Weber.

This truly is a professional organization…read more The installation was seamless, perfectly done and they had no problem when I needed some adjustments made. They were always most willing to answer my questions and never made me feel that I was imposing, or a bother. They removed my old air conditioners, installed the heat exchange system and left my house in perfect condition. It's as if they were never there, except that I now had a wonderful new system. I can't praise Cool Pro enough and I can say without a doubt, that they are one of the best companies that I have ever dealt with. This truly is one of the most professional and the best organization and they were most reasonable!
