“The team at Elite heating and cooling did an excellent job installing my aunts AC System. No hidden fees and the estimate was spot on. Highly recommend. We are very happy!!“

“I was able to get an appointment next day which was great. Phil was professional and experienced and was able to answer all of my questions with honest answers. He conducted a very thorough review, even more than I expected.“

“Still Great Service and always a Friendly Delivery! I make it a point to go out and say Hello when they arrive since I'm sure most of their deliveries have little interaction and I appreciate their service. Just remember who's out there in the Bitter Cold helping countless families stay warm all Winter. Thank You!“

“Bobby O's came highly recommended and now I know why. Had a hot water heater installed today and everything went smoothly from beginning to end. Crew was on time, worked quickly and efficiently. Wouldn't use anyone else for my HVAC needs. Highly recommend.“

“Absolutely fantastic experience with Airmax! They came to service the HVAC system at my boutique studio and I couldn’t be happier with the result. From start to finish, they were prompt, professional, and incredibly knowledgeable. The technician explained everything clearly, answered all my questions, and made sure the system was running efficiently before leaving. It’s clear that Airmax takes pride in their work and genuinely cares about their customers. The studio feels comfortable and climate-controlled again—huge relief for both me and my clients. Highly recommend Airmax for any HVAC needs, especially for small business spaces like mine!“

“Brian and his team did a great job on a recent HVAC challenge I had from a big HVAC firm that failed to notify me that something was done incorrectly by a builder.

He took the time to explain to me exactly what needed to be done, why and then got it done. On time and under budget. I'd highly recommend this firm.“

“My oil tank started leaking and needed a replacement in a short time frame. Thanks to John (Jr), he went above and beyond with relocating the new tank upon my request, along with clean up and tuning my boiler to his recommendation to make it more efficient. A huge thank you! I will not hesitate to call for future needs.“

“The boiler stopped working, would turn on then turn off in a few hours.. No hot water!
I called Jet Air, and they scheduled me in quickly.. The technician Nick, arrived promptly, he was professional, courteous and he knew his boilers. He diagnosed it immediately, needed a new valve, he replaced it and we had hot water again! The price was reasonable and fair. I would definitely recommend this company to friends and family.. Very knowledgeable and professional!
Thank you again Jet Air!“

“I have dealt with contractors and service people for over 40 years, and as a retired aerospace engineer I will state that Absolute HVAC is ABSOLUTELY the most straight forward, knowledgeable, ethical, efficient, and conscientious of all the others of any kind without a doubt, especially those dealing with HVAC systems. I got to know them very easily; Absolute is owned by Dominick after owning and running a successful 40-tech HVAC contracting business in “the city”. Being knowledgeable and too young to retire, he brought his business to Long Island.
Everyone from Absolute was great to work with. My compressor froze during the heatwave in July so I called Absolute and since all the techs were out, Dominick himself came right away. Together we quickly verified the root cause of the failure. After calling all the Long Island HVAC equipment suppliers, Dominick located the necessary replacement 2-Stage condenser unit in PA with the correct specs for my air handler, got it here in a day and had his guys install it efficiently in what I considered record time. The work performed by lead tech Faze, and Moses was impeccable. I asked them “How is Dominick to work for? Does he take care of you guys?” Their response was simultaneous and immediate; they both said: “Great! Oh yeah, yes, he does!” This response by the tech staff, says a lot of positive. I highly recommend Absolute for all of your HVAC needs.
Note: I did not know Dominick prior to this HVAC job, and I have not received any compensation for this post. I merely said that besides giving a nice tip to the techs, I would find a place to leave a review.“

“Wonderful company to deal with they call before they're going to come they're on time they do deal diligence while they're here and they're fairly priced.“

“Wonderful crew, curteous, clean and extremely polite. John and his crew are on top of their game.“

“Mr. Felix and his assistant came to our house yesterday to fix some water circulation problem in our heating system. The job was done very well - clean, precise, and professional. We appreciate not only his good job, but also his communication to us. He explained how the new parts fix the problem so that we have a full confidence and a peace of mind. Thank you.“

“Excellent communication, service and timeliness. I have a high efficiency Bosch propane burner and it’s hard to find a qualified plumber to maintain. That’s exactly what I got with McIntosh. Thank you!“

“Angel and Raphael were wonderful. Hard working and vey knowledgeable. I will definitely use this company again“

“Like and Cody did a great job. They were professional and efficient and explained the work to be done.“

“MR HVAC:
This company is amazing. Works with us and especially Adam Parsons from Vendor Relations has been a huge help with our company and making sure that if there is something that we are doing wrong or there not happy about he lets us know.“

“Brian and his team arrived to my home with 5 installation trucks and crew. His team was professional, clean and knowledgeable of the products they were installing. Once completed, Brian sat down with my wife and I and gave us a detailed class on the operation of the 5 new mini splits.
I would highly recommend Twin Air.“

“David is a great tech . He is very knowledgeable and took his time and made sure bleeding of furnace and thermostat was done properly.No more cold nights!?“

“Can’t say enough good things about the guys at Advance. My Ductless system went dead on a Friday afternoon after 12 years during the recent heatwave. They came and had me up and running with my new unit that Monday.Calls to other companies told me at least a week or more. Very Professional Thanks again“

“I couldn’t be happier with my experience with Long Island Burner King. From start to finish, they made my oil-to-gas conversion incredibly smooth and stress-free.

The pricing was very fair and competitive, especially given the quality of the work and the equipment they selected. What really stood out was the speed—they got the job done faster than I expected without cutting any corners. The crew was professional, knowledgeable, and respectful of my home throughout the entire process.

Their service and follow-through were truly exceptional (Jennifer is amazing). They kept me informed every step of the way, handled all the details, and made sure everything was working perfectly before wrapping up. Even after the job was done, they were responsive and available for any questions.

If you’re considering an oil-to-gas conversion, I highly recommend Long Island Burner King. Absolutely amazing experience.“

“Joe, Christian and his team were amazing! Added insulation and storage platforms to my attic, job was finished very quickly and performed professionally. Would recommend to everyone! Thanks again!“

“Varsity came through for our family back in October when our oil burner was leaking and after spending $500 with another company, it still wasn't fixed. Conner J. Came by, diagnosed the problem, set up a time to fix it, came when he said to do the work successfully, and then we had him back to do the annual tune up too because we were so happy with the service that we now wouldn't trust anyone else. Thank you!“

“Scott did a great job, and US Air was accommodating with my schedule, very pleasant experience.“

“Needed to have my cesspool pumped. Called Ray The Plumber and they were very helpful and explained the whole process. Was told when to expect the technician and Ryan arrived on time. He was very thorough in assessing the problem, gave me a quote and completed the service while taking care of the lawn. I’m very pleased with Ray The Plumber and would definitely use them again.“

“Steve called to let me know is he would arriving shortly. He was polite, explained the maintenance process and answered my questions. I would highly recommend“

“Al helped bail me out of a bad install from a different company 18 years ago and I have never forgotten. So when it came time for an update of my current system Cool Air really was the only Company I called......The price was fair and the job was done in a day. As other reviewers mentioned the job was done neatly and the installers including supervisor Stephan were friendly and knowledgeable. I had a small issue with a motorized split damper (which was my original unit) and my thermostat and Al sent a tech guy out who reprogrammed all my thermostats in a matter of minutes and no issues after that. Needless to say we are very happy and would highly recommend them“
