Maintenance Agreements

Q: Why do I need a maintenance agreement?
A: By maintaining your HVAC equipment, you are also saving energy and reducing your utility costs.

You can extend the life expectancy of your system with regular cleaning and filter changing. This maintenance will also increase the efficiency of both your heating and cooling equipment.

Koch Heating And Cooling’s maintenance agreement program provides for the detection and correction of minor issues before they become major problems. Taking good care of your equipment could mean additional years of reliable service and operation.

If your equipment malfunctions, you automatically get 10% off of any parts or labor needed for repairs. Our maintenance agreement customers get priority response. We will respond to your needs when they arise. We guarantee service within 24 hours of your request.
