Heat Pump + Electric Air Handler Maintenance or Repairs We Offer in O’Fallon, IL

A heat pump and electric air handler is a smart way to keep your home cool in the summer and warm in the winter. Modern heat pumps are an efficient way to keep your home warm, but they still need regular maintenance once a year.

The difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10% to 25%, according to the U.S Department of Energy.

With our maintenance plan, you are taking a very important step in prolonging your system’s life. Our technician will examine your heat pump according to the manufacturer’s instructions as well as inspect the filter, blower, and indoor coil for dirt. We will also verify air flow, refrigerant charge,  as well as blower speed. We look at the overall controls making sure heating is disabled when the thermostat is set to cooling and vice versa.

Our flat rate of $189.00 is a small investment and pays for itself with the money you save in future repairs.

This worthwhile plan is perfect for the homeowner that values comfort and peace of mind.
