There are a few signs that you should have your ducts cleaned. If you notice dust & dander built up on your air return registers (the little rectangular grills on your ceiling or walls throughout your home); if we find any signs of mildew or mold in your HVAC system; or if you find rodents living in your duct work or attic. Reach out to us. We will get our certified Temper Techs on the job. Here at Temper Mechanical, we use a duct-cleaning checklist to ensure we clean and sanitize our customer’s ducts as effectively as possible. This includes using an endoscope to inspect every inch of your duct work, a roto-brush to gather the dust and debris to bring outside, and a sanitizing system to completely clean your ducts.
