For the best results from professional air duct cleaning, it’s important that technicians thoroughly access and vacuum out dust and contaminants from all parts of your duct system. This blog post covers the key areas that need to be cleaned for maximum effectiveness.
Supply and return ducts must be vacuumed.
These are the main ducts that distribute conditioned air throughout your home via registers and vents. Dirt builds up over time inside supply ducts carrying air into the house, and return ducts carrying air back to the HVAC unit.
Air plenums should be targeted.
In addition, plenums are the large, open spaces where many ducts merge together. They tend to collect a lot of dust that then gets circulated throughout the system. Thoroughly vacuuming plenums removes trapped contaminants.
Furthermore, register and grille covers must be removed and cleaned. These metal covers over air ducts and vents restrict access to the actual ductwork behind them. Covers need to be taken off so the openings they conceal can be properly vacuumed out.
Moreover, the HVAC unit itself typically needs maintenance. The indoor coil, fan, cabinet, and blower compartment should all be inspected, vacuumed and cleaned as part of a thorough duct cleaning job. A dirty HVAC unit cannot properly condition air.
Also, air handlers that distribute air through the ductwork frequently require attention. The casing, fan, coils and drip pan inside air handlers build up contaminants over time and need vacuuming and cleaning to ensure air reaches registers free of dust.
In summary, to be confident your air duct cleaning service thoroughly addressed all portions of your ductwork that needed attention:
- Supply and return ducts running through living areas were vacuumed.
- All plenums where multiple ducts join together were targeted.
- Register and grille covers were removed to expose duct openings for vacuuming.
- Technicians inspected and cleaned any exterior ductwork accessible in attics,crawlspaces, etc.
- They cleaned the indoor coil, fan, cabinet and blower compartment of your HVAC unit.
- The air handler casing, fan, coils and drip pan were also vacuumed and cleaned.
The more comprehensive a professional duct cleaning job, with all areas of the duct system properly targeted, the cleaner your indoor air will be and the longer clean air will be able to circulate throughout your home.
