Conditioned air moves through the ducts and carries loose particles like pet mold, mildew, dander dust, bacteria, and pollen. These things aren’t removed if your air filter has become blocked, the system’s components have become dirty, or particles are left to linger within the air ducts.
If you are experiencing bad indoor air, you will also be more likely to be surrounded by dust which could affect anyone with asthma, allergies, or other respiratory issues. Regular and professional HVAC repair in Phoenix by LJ Refrigeration Co., Inc. can benefit your air quality greatly.
