"Joe was responsive to my request to have his technician Dean cut out a leaking shutoff gate valve on the plumbing to my outdoor hose bib and replace it with a new ball valve. Dean did a thorough and professional job. I subsequently contacted Joe for a second unrelated job to clear out a blockage in my basement lift ejector pump which Dean was able to take care of and leave the area perfectly clean and dry"

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!"
