We're talking about your home heating and cooling systems, of course.

RepairsAnnual Tune-up & Inspection.


The best way to protect your investment in your current home comfort systems is with routine maintenance. At Mathis, we perform annual tune-ups and inspections. Think of them as insurance policies to help your systems last longer and cost less to run. Plus, we help you save money on your energy bills.

Our multi-point tune-ups and inspections consist of these and other equally important steps:

  • # Clean your filters, and replace them if necessary;
  • Check for carbon monoxide or gas leaks;
  • Inspect the safety controls;
  • Lubricate and inspect all motors;
  • Inspect the seals and insulation of your air ducts… heat loss from leaky, un-insulated ducts reduces the efficiency of your heating system by as much as 30%;
  • Check and adjust thermostat for accurate system control;
  • Visually inspect your heat exchanger for cracks;
  • Examine and calibrate refrigerant controls (AC).
  • Verify proper amperage and voltage for your compressor and condenser motors (AC).
