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!"

Open Loop Geothermal Heating, Cooling, Hot Water Systems use drilled GeoExchange supply and return ground water. energy wells. Closed Loop Geothermal systems use drilled Geoexchange energy wells with fluid filled U bend underground piping to transfer this free Solar Powered Geothermal Energy. Standing Column GeoExchange energy wells are a hybrid of open and closed loop using a single well in rock formations to transfer this free energy. So as the saying goes let's " Drill Baby, Drill " for the right reason.
