Often you hear the recommendation that you should change your air filters regularly, but why? And how often? There are many answers to both questions, and they can differ based on the size and style of your home’s heating and cooling. You can reduce many possible HVAC problems by understanding why and when to replace the air filters in your home.
When your air filters get too dirty, they can seriously affect the efficiency of your HVAC system, which in turn increases your energy costs. Your system will need to work longer and harder to heat or cool your home because the air flow is stifled by an old air filter, and that extra work can shorten the lifespan of your HVAC unit.
One room might feel warmer than another, and that is because of that limited airflow — inconsistencies throughout your house that result in uncomfortable spaces. You may be tempted to increase the setting on the thermostat because of the differing temperatures.
The fan on the furnace will put in some overtime hours, and it will wear out. A system failure can be a costly fix, and that may come at a later time after your energy bills have already seen a big spike.
Dirty air filters also lead to dirty air ducts, and that will lead to dirty air. The air quality in your home will diminish because the old air filter can no longer stop bad particles from getting through, and those with health issues and allergies could face some troubled times.
Air filters are relatively inexpensive compared to a full fix on your HVAC system, so they need to be regularly replaced. “Regular” for most homeowners is once or twice a year, but you should consider changing them every other month.
Not all air filters are the same, but you should be able to find the right shape and size for your home’s HVAC system. To learn more about bettering the air quality of your home, and why replacing air filters is important, call Sharon’s Heating and Air Conditioning today at (734) 425-1415.
