We have outstanding ratings and provide superior customer service. Feel free to check us out and give us a call for more information.

"I have had gone through many large construction projects over the past 15 years at my residence. Hands down, this was the most professional, honest and insightful company I have ever dealt with. From the beginning they offered advice that saved me thousands of dollars and followed through on every single aspect of the installation. When the inevitable snags hit due of the large scope of the project they provided the perfect remedies. I would hire again in an instant. If anyone wants to talk details I would be more than happy to oblige."

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 56 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!"
