Knoxville Duct Cleaning to Increase the Efficiency of your HVAC System

A Heating, Ventilation and Air Conditioning system, abbreviated as an HVAC, needs regular maintenance to ensure it remains energy efficient, clean and has a lasting lifespan. SERVPRO production manager Cody Taylor shows you how to spot the signs of dust buildup in your HVAC by checking both the return and supply side of your system.

To understand when your HVAC requires cleaning, you need to inspect the return side first. The return side of your HVAC system is usually the biggest grated register in the home. This access point is where ambient air is drawn into the ventilation ducts and circulated within the home after conditioning at the air handler. This doorway uses both grating and filters to capture the dust and debris from entering the network but, over time, these filters become less effective, clogged, and need replacing.

Removing the large ventilation panel and filter allows you to check for grime, mold, or debris on the interior walls of the ventilation shaft. If there is lots of debris on the interior walls, it indicates that your filters are no longer effective in maintaining a clean airflow into your HVAC system. Any debris that does pass through the filters is now being circulated throughout your system and home, negatively affecting indoor air quality (IAQ.)

The second element to inspect is the supply side of your HVAC system, which is done by examining the vented registers in the ceilings or flooring with a plenum system, in each room. Supply panels are where air from your HVAC is circulated into rooms around your home. If visible signs of grime, soil, or staining is visible at the exterior or the supply duct shows foreign matter, it is time for a professional cleaning.

If you notice either of these signs on the return or supply side of your HVAC system or an unpleasant odor, contact SERVPRO of Rocky Hill / Sequoyah Hills / South Knoxville at (865) 862-8907.
