Heating and cooling costs go up when HVAC filters get clogged with dust, dirt and lint. When the HVAC filter is dirty the blower and motor have to work harder to keep your house comfortable. This is a common problem that is easily avoided.
During the months when your HVAC unit is running consistently, make a point of changing the filter once a month. If the same system is used for air conditioning, consider changing the filter throughout warmer months as well. The simple process of changing the filter can save money on heating and cooling costs and prolong the HVAC unit’s life, saving you much more on system replacement costs
