Common Air Filter Service Questions

Includes cleaning, removal of contaminated materials, and air filtration.

Regular HVAC filter changes, deep cleaning, and air quality monitoring help maintain a healthy environment.

If you do not regularly change your HVAC filter, it will become clogged with dust, dirt, and other contaminants. This blockage forces the system to work harder to circulate air, leading to higher energy bills, poor temperature regulation, and increased wear on parts, which can cause more frequent breakdowns and shorten the system's overall lifespan. Additionally, a dirty filter that no longer traps contaminants can lead to poor indoor air quality, potential health problems, and even complete system failure.

Air filters with a MERV rating of 11 or higher need to be changed every three to six months. If your filters are incredibly strained because of environmental factors, such as living in a smoggy, pollen-rich area with a large household, you may need to change your filters every two months regardless of the MERV rating.

Washing your carbon filter can damage the fibers and make it less effective. While removing the dust from the filter gently is possible, we don’t recommend you wash and reuse the filters once they have reached the end of their lifespan.
