In the colder months, you may expect your heater to circulate warm air though your home. But what if that air is cooler than you expect or doesn’t flow as much as you think it should? Sometimes, this is a problem associated with dirty filters.
As your filter collects particles, it becomes a barrier to air. The pores are large enough to allow air to pass through, but the particles reduce that ability. Due to this reduced air flow, your system needs to push harder to heat your home.
The easiest way to prevent this from happening is to set the reminder to change your filters every 3 months, you can enjoy great airflow and warm air. An added benefit of changing your filters, is you will extend the lifespan of your HVAC unit.
