A/C Installation

Purchasing a new air conditioner is one of the best investments a homeowner can make, and our installation technicians do everything possible to safeguard that investment. Every installation visit begins with a full load calculation to determine the exact capacity needed to keep the whole home cool, and we recommend a system calibrated to meet that need. Our factory-trained technicians work diligently to install every system up to Carrier's standards and take care to thoroughly test the machines before leaving the home.

A/C Service

Our A/C service team works tirelessly to keep our customers' air conditioners up and running at maximum efficiency, and we offer annual A/C service agreements to give every home's cooling system the yearly attention needed to keep working reliably. Whether maintenance is as simple as changing an air filter or as complex as calibrating the entire control system, our technicians are ready to get the job done, saving money on utility bills and preventing costly A/C repairs down the road.

A/C Repair

When equipment does fail, our A/C repair team is ready to step in and fix all makes and models. We send our teams out stocked with all of the equipment they need, and we have access to even more through the Carrier network. In addition, we offer 7-7-7 services to keep our friends and neighbors cool all week long. Whether you need a new system, routine maintenance or an urgent repair, contact McWilliams & Son Heating and Air Conditioning to schedule an A/C service visit today.
