4 Signs It’s Time to Change Your Air Filter

Regularly changing your HVAC system’s air filters will keep your home clean and your family healthy. Take a look at these four signs that it might be time to contact Weather Engineers to have your air filters replaced.

1. Problems With Allergies or Asthma

A clogged filter will increase the air pressure within your ducts. When the air pressure becomes too high, it could force air and outdoor allergens around the filters instead of through them. Over time, you might begin to experience issues such as a sore throat, red eyes, and a runny nose.

2. High Amount of Dust in Your Home

All homeowners should be wary about an unusual amount of dust in their home. A clogged air filter is one of the most common causes of extra dust, but you might also be dealing with insulation problems such as damaged weatherstripping or cracks in the ducts.

3. Uneven Temperatures

Uneven temperatures throughout your home is another clear sign that something is wrong with the HVAC system. A well-maintained HVAC system should be able to keep every room in the house at a consistent temperature. Even if your filters are not ready to be changed, you should still have your system inspected by a technician if you have noticed this problem.

4. High Energy Bills

An air filter that has become clogged with dust will force your heating and cooling systems to work much harder. This generally results in higher energy bills during the hottest and coldest months of the year. Changing your filters is a great way to keep your HVAC system running at maximum efficiency.
