Air Duct Cleaning
Wanted to give some facts about air duct cleaning in this issue. Spring has arrived and it feels like summertime already! 80 degree weather in March will make you turn you AC unit on in a flash! So here are a few facts about how to maintain your system and get the best out of it while saving money!
Air Duct cleaning basics:
  • Air-duct cleaning generally includes cleaning all parts of a heating and cooling system, including ducts, registers, grills, diffusers, heat exchangers, coils and drip pans. Services also typically include motor and housing cleaning. Providers use physical cleaning methods such as scrubbing or brushing and chemical methods such as biocides and sealants to clean air duct systems.
  • Air-duct cleaning can provide health and financial benefits to homeowners. Dust and other debris build-up in the heating and cooling system of a home encourages mold and bacteria growth if moisture enters the system. This causes health problems and allergic reactions in some people. Dirty systems also run less efficiently; clean systems usually break down less often and last longer. Cleaner, more efficient systems require less energy to operate and thus lower energy costs for the homeowner, according to the National Air Duct Cleaners Association.
When Does Duct Cleaning Make Sense?
There are several situations when duct cleaning could make sense (although there is little research data to support this).
  • If you have a problem with water in your ducts, this may result in mold growth in the duct. In this situation, solve the water problem first, clean and disinfect the ducts where mold growth has occurred, and have the rest of the ducting system cleaned as well. In some cases, it may be necessary or more cost effective to simply replace the affected duct areas.
  • If you are moving into a newly constructed house, and have doubts about the diligence of the construction crew, duct cleaning can be useful. Drywall dust, fiberglass pieces, and sawdust have no place in ducts. Duct cleaning will also catch the odd occurrence where lunch bags or soft drink cans have fallen or been swept into ducting. For similar reasons, duct cleaning may be advisable for older houses following major renovations.
  • If you are having trouble with furnace airflow, a duct cleaning could reveal significant blockages. Have the ducts cleaned before you embark on more expensive duct replacement or rerouting to solve an airflow problem. Cleaning of furnace and air conditioning components (e.g. furnace fan blower, air conditioning coil, humidifier, furnace heat exchanger, etc.) has been shown to make some difference in duct air flow.
  • If you look in the return air registers and see an accumulation of debris in the duct below, you may want to have it removed. CMHC research showed that return air ducts, which are relatively big and have slow moving air, are generally far dirtier than the supply ducts.You should be able to accomplish much of the return air duct cleaning with a household vacuum cleaner after removing the register grill. For example, households with hairy pets or young children may find it necessary to inspect their return air ducts more frequently. Do not expect any difference in airflow or house air quality after this cleaning.
