When is the best time to clean your air ducts?
Proactive builders offer our service before the construction dust they leave (sheetrock from floor sanding etc.) coats return ducts, air handler coils, fan blades and motor restricting airflow reducing performance and air handler and compressor longevity. This construction dust will also start to grow mold on air-handler components and supply ducting when the air conditioning systems run. One good indicator of this without opening up the air handler or supply ducting is to look inside a heat pump system that has supplemental heat strips installed at the top of the fan. All summer long bypassing dust will accumulate and grow mold on these strips that are similar to the heat strips on the bottom of your toaster. When these strips turn on the first cold day- that’s the burning smell you get when these heat strips glow red. The rest of this by-passing dust will grow mold on the inside of the supply ducting especially if its interior lined or a porous fiberglass duct board.
I have been told duct cleaning can damage ducts so my only option is replacement? This is true and I have said for years we offer a better method than air duct cleaning companies that damage porous ductwork and plastic flex able ducts with rotary brushes and then apply a Biocide ( EPA does not recommend to be used on porous ducts) that only kills a small portion of mold by drying it out. It then becomes an airborne contaminant and only will grow back as moisture returns, and then the “mold is gold“ heating and air conditioning contractors want to replace the duct work.
How do you clean ductwork differently? Our employees have been with us for an average of 7 years. We lay sheets under every return and supply duct. Return and supply grills are removed. Using suction at the return, we clean the return ducts with low velocity nozzles that remove the dust without damaging brushes. The air handler components are cleaned by air washing the back of the coil forward to remove impacted dirt that brushing alone can’t. The coil pan is wiped and sanitized and the drain lines are vacuumed. Fan blades and motor components are air-washed. EPA Registered mold inhibitor coating applied to air handler liner. Supply ducts are cleaned, coated and permanently sealed. With good filtration and maintenance duct cleaning should not be repetitive.
