Maintenance Plans

Why Are Maintenance Plans Important?

Did you know that your air conditioning unit runs about 1,600 hours per year, and your heating system runs about 1,400 hours per year?

You rely on your heating and cooling system every day. Similar to a car, your heating and cooling system requires routine maintenance to operate efficiently, safely and reliably for the expected life of the unit.

Maintenance on your heating and cooling system is something that we don’t often think about, yet it has one of the most dramatic effects on our utility bills. Manufacturers of heating and cooling equipment recognize that bi-annual maintenance of your HVAC system is necessary for continued efficiency, safety and to extend the life of your equipment.

Keep your HVAC system tuned up bi-annually to extend the life of your unit. We offer a bi-annual Maintenance  Plan to keep your Oklahoma heating and cooling system in peak condition all year long.
