Serving Long Island with Pride

Reliance Heating and Cooling is proud to consider itself one of the most reliable heating and air conditioning service providers on Long Island. We supply and install quality, name brand parts backed with a warranty that is as strong as our name. We offer a full one-year part and labor warranty on every service call we provide.
