What is HVAC efficiency?

If the cost to heat and cool your home in Stillwater is biting into your budget, HVAC efficiency is something you should be concerned about. It means using the least amount of energy to produce the heating and cooling you need to make your home comfortable. Whether your system is several years old or brand-new, here is what you need to know about HVAC efficiency and what affects it.

Air Filters

You can immediately improve HVAC efficiency by changing your system’s air filters if they are dirty. A filter that is clogged with dust, pet hair, and other debris puts added stress on your system because it compromises your airflow. This affects its efficiency and causes it to use more energy to heat and cool your home. During times of high use, you should check your air filters each month and change them as needed.


The efficiency of your HVAC system depends on the performance of all its components. A lot of focus is placed on furnaces and air conditioners. However, the ductwork in your home can hurt your system’s efficiency. It is important to have your ducts cleaned and inspected for leaks, including cracks and loose joints that impact HVAC efficiency.

Preventive Maintenance

Having your HVAC system professionally serviced twice a year helps maintain its efficiency. During a preventive maintenance service, our NATE-certified technicians make needed adjustments and repairs that keep your HVAC equipment running smoothly. When your system is running smoothly, it is more energy-efficient than systems that are not serviced according to manufacturers’ specifications.


Furnaces, air conditioners, and heat pumps that are manufactured today are much more efficient than those put on the market just a decade ago. Today’s furnaces are required to have a minimum AFUE of 78%, and air conditioners must have a minimum SEER of 14 in Oklahoma.
