Three companies. Many specialties. One focus.

In 1970, Irish and Mary O’Connor founded the company on two principles, comfort and service. Today their dream has grown to become the O’Connor Group – with expertise in every phase of indoor comfort systems.

But our philosophy is still the same: Serve our customers, make them comfortable, do the job right.

We’re proud to offer our customers heating and cooling products from Siemens, McQuay and York® – as well as other fine manufacturers. These professional affiliations include valuable training for our employees and our customers regarding the latest products and technology.
