Did you know regular maintenance of your HVAC System is beneficial to the life and operation of your equipment!
A few other tips for year round is to make sure your heating/cooling vents and return air grilles are clear of furniture so that the air can flow smoothly around. Its a good idea to remove the grilles and vacuum them front and back to remove dirt, dust and dander. Also while the grilles are off vacuum down into the heating duct or return air to remove any cob webs (you may be surprised!) and dirt caught in them.
