A. We recommend having your heating & cooling system serviced twice in the year to keep it working at maximum efficiency, to find and fix small problems before they become major issues, and to avoid needing service during extreme weather conditions when everyone needs help and the wait for service can be longer than normal.

A. Yes, as your filter gets too dirty its ability to capture and hold particles decreases and more dust and dirt can come through the filter. It’s important to use a good quality filter, typically in the 8-12 MERV range. Below MERV 8 it does not capture enough particles and above MERV 12 it is too restrictive to air flow.
