To keep your HVAC system running as efficiently as possible, you should typically replace your air filter based on the manufacturer’s recommendations. However, there are certain instances where your filter may last longer than expected or need to be changed more frequently. Here are four signs your filter needs to be replaced.
- The filter looks dirty.
Perform a visual inspection of your air filter. Does it look dirty or damaged? Holes and wrinkles can allow contaminates to enter your HVAC system, affecting the airflow in your home. If the filter has dirt and dust on it, that’s another clear sign that it needs to be replaced. Clogged filters will restrict airflow and force your HVAC system to do more work than it has to.
- A family member with allergies is experiencing worsening symptoms.
Does anyone in your household suffer from asthma or allergies? When symptoms worsen, your air filter may be to blame. Old, damaged and dirty air filters can allow dust and debris to circulate throughout your home. A new filter, on the other hand, not only traps dust, but it can also help stop dander, pollen and bacteria from entering your system.
- Your home is dustier than usual.
Dust-covered furniture, walls and vents are all telltale signs of a bad filter. Clogged filters can’t do their job of removing pollutants from your indoor air, contributing to poor indoor air quality. Besides adding to your home’s dust accumulation, a dirty filter can damage your HVAC system, so it’s important to replace the filter on a regular basis.
- It takes a long time to heat or cool your house.
To reiterate, a dirty air filter can limit the amount of heated or conditioned air circulating in your HVAC system. As a result, your heating and cooling system may cycle longer than it usually does. As components work harder to pump out heated or cooled air, your HVAC system experiences reduced energy efficiency.
In addition to replacing an air filter, there are other preventive maintenance procedures that should be performed to keep your air conditioner or furnace working in peak condition. Contact Custom Aire today to learn about our maintenance agreements.
