How to Clean Ducts in Your Gas Furnace?

Unfortunately, most forced-air heating systems, whether gas, electric, or oil, lack appropriate filters. As a result, most homes' ducts contain an accumulation of dust and grime that has accumulated over time. Paper clips, money, toys, potato chips, and other inhabitant artefacts tend to amass in ducts. Construction debris such as sawdust, nails, plaster, and other materials fall into the ducts and are frequently left behind, even in new homes. Both the return and supply ducts will contain these elements.


Carpets, beds, mattress pads, and clothing are all common places for dust mites to reside. Because these insects require a steady supply of food to survive, they won't last long in most duct systems. For most of us, dust mites are an unavoidable part of life, and totally eliminating them from our homes is tough.


Following a thorough visual check, you may want to try cleaning your home's ducts. Using a flashlight and a mirror, remove the grills from the return and supply ducts and inspect them (to look around the bends). It's frequently impossible to get to the ductwork near the furnace without dismantling a few duct connections.A household vacuum or shop-vac will usually suffice for typical dust and debris in those locations that you can reach. The presence of moulds and fungi, as well as excessively dirty or oily ducts that you can't access, suggest professional cleaning.


Professional duct cleaning services have traditionally used a truck-mounted industrial vacuum and bag filters. From the truck, a big air duct is channelled inside the house and connected to the ductwork near the furnace. The strong air flow induced by the industrial vacuum then "sucks" the ducts clean.


Depending on the type of debris, high-velocity air blasts may not be sufficient to clean the entire ducting. A thin film of oil or dust is frequently present, which can only be entirely removed by mechanically washing the ducts. Brushes, rotating whips, and other devices placed into the ducts are used by some duct cleaning services. These cleaning tools aid in dislodging material from duct surfaces so that it may be cleaned out.


Following duct cleaning, some businesses employ foggers or sprayers to treat the interior of the ducts with various chemical solutions to kill moulds, fungi, bacteria, and other biological growth. The only substance of this type currently approved by the Environmental Protection Agency for duct treatment is Oxine.


Unless you utilize a decent filtration system, your ducts will begin to collect dust and debris again after they have been cleaned. For the very small particles that cause lung issues, most "hardware store" filters are useless. Pleated filters with an efficiency range of 30% to 60% are recommended for general use.
