AR Air has been proudly serving our community since 1999, providing top-quality heating, cooling, and appliance services. We specialize in AC, heating, and water heater solutions, and we’re a Fujitsu Elite contractor for ductless systems. Our expertise also includes rooftop package units, PTAC units, humidifiers, and WiFi thermostats, along with repairs and maintenance on all refrigeration systems.

"Ralph looked over everything thoroughly and gave us an estimate. He came to do the repairs in less than a week. Ralph explained everything concisely and was happy to answer any questions. He is very knowledgeable, reliable, and careful. We have older units that were difficult to take apart and put back together; however, Ralph knew exactly what to do and handled the problem easily. He was very professional, careful of his surroundings, and cleaned up afterwards. He even helped us move some of the furniture back, which was unexpected and kind. Both my wife and I were impressed by his superior service. To top it off, Ralph is a great person! We are delighted with the wonderful job that he did. Highly recommend!"

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 54 years of exceeding customer expectations. All Weather provides sales, installation, service and maintenance of residential and commercial heating, air conditioning & water filtration systems.

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"
