We are a full-service Fuel Oil, Propane and HVAC contractor serving the Carlisle Area since 1982. We provide heating, air-conditioning, and plumbing installation for new construction or existing buildings and homes. Installation estimates are always free.

The Company was started by Michael Morrison as a sole proprietorship. In 1992 the company incorporated and renamed the service division CPI Mechanical Contractors with Michael Morrison as the President. In August of 2002, we relocated to 1524 Commerce Avenue, Carlisle, just off of the Plainfield exit of I81. The new facility allowed us to expand our office and warehouse areas to better serve our customers needs.
