“Central Air Systems Inc installed our new central air and heat pump this week. They were excellent! The whole crew were so nice and knowledgeable, Kyle, Ryan, and Chris did an amazing job. My house was left spotless! During the install they made sure we were happy with the location of the vents and afterwards showed us how the thermostat works. I’d give them 10 stars if I could. Extremely happy with the whole company! The price was also competitive and they handled the rebate process as well. I highly recommend them.“

“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.“

“Had a very good experience with Above All Electric. Knowledgeable, friendly and courteous. Would highly recommend.“

“I've had this HVAC system for several years, and it's still as reliable and efficient as the day it was installed.“

“On Monday 4/28/25 a Cunningham crew cleaned my home's air ductwork, floor vents, air returns, dryer duct, etc. The crew head even inspected my heating system chimney and decided it did not need to be cleaned. They were a delight to work with. The crew arrived on time, immediately protected my rugs and walls, and got right to work. The whole process took 4 hours for my modest sized home, during which time the crew head kept me informed about their progress. They moved, and replaced, furniture as needed. My only responsibility was only to keep our cat safely secured. Thank you Cunningham!“

“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.“

“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.“

“Great website, very easy to use, gets me the best oil prices and referred a great company to fix my boiler for less than what the contract companies wanted just to come give me an estimate.“

“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.“

“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!“

“I needed a plumber asap and Assured understood that which was great. The office is run by Dawn and she was so helpful. It wasn't a major job but Quinn the plumber/owner was great. Pleasant, respectful and very knowledgeable. I highly recommend this business. I also appreciated the understanding of the urgency to get my bathroom sink fixed. I called on Sunday and my sink was fixed on Monday.“

“Outstanding service and very professional! Thank you so very much for looking into the issue with my heat pump! I highly recommend and appreciate them! Thank you so much!“
