If your heating & cooling system has flexible ducts and if they are over 10-15 years old, they most likely need to be replaced. Older flexible ducts often have very poor insulation which decreases your home’s efficiency.

The best way to ensure that your air quality is clean in your home is to have regular maintenance and assessment. Customer’s Preference, LLC can set you up on a plan to make sure the air you’re breathing is always clean.
