Duct cleaning is one of the maintenance issues that many home owners tend to put off. It is, however, just one of those things that are completely necessary to do in order to maintain your home. Clean ducts not only improve the quality of your indoor air but also ensure that the air is flowing properly through the house.
Some vermins also like to nest in the ducts since they provide a warm environment that seems safe. Sometimes ducts can be infested with rodents and insects, which can be quite a cause for concern.
Overall, it's a good idea to get your ducts cleaned out once every 3- 5 years. On the other hand, if you have been remodeling and renovating your home, it's best to get them cleaned to remove dust particles and debris that could have made their way down into your heating and cooling system. It's also recommended that you clean your ducts when you move into a new home if you aren't sure of the time they were last maintained.
A thorough cleanup of the HVAC should take about 3 hours to complete. The procedure should include the drain pan, the blower or the fan compartment, the blower or the fan blades and the cooling coils.
Before hiring any professionals, make sure that they belong to a Canadian trade association like the National Air Duct Cleaners Association. As well, be wary of any company that is advising the application of biocides or disinfectants. These types of cleaning products haven't been registered or approved by the Pest Control Products Act of Canada.
Duct cleaning should be considered as a necessary part of home maintenance. It only needs to be done every few years and is an easy way to keep the indoor air quality of your home at its best.
