What parts of an air system should be cleaned?
There are three major parts to every air system. The supply and return grills, the interior surfaces of the supply and return air ductwork, and the furnace or air conditioner air handler. All three components must be cleaned when doing an air duct cleaning. If only one or two of the components are cleaned and any part of the system is not done, then contaminants from the third component will rapidly contaminate those that were cleaned.
Alot of duct cleaning companies in the Toronto area quote prices to clean the ductwork and air vents only, and then either skip the very important step of cleaning the HVAC equipment or air handlers, or they ask for exhorbitant additional charges to clean these components if you wanted to have those parts of the system done also.
I have learned this from discussions with a number of air duct cleaners over the years. The price that got them in there was what they consider to be an ”introductory” price. Now that they’re in there, they’re going to nail you with extra charges if they can, and if you don’t want to pay extra then you’ll get what you pay for.
At City Duct, every job that we do, whether it is a home in the Toronto area or a business, it always includes the cleaning of the HVAC equipment.
When cleaning the air duct system(s) in a home, we clean the furnace fan, the inside air conditioning coil, the furnace plenums and the air filter. On a commercial job we would always clean the air handler or rooftop equipment, and that always includes the fans, coils (both evaporator and condensor coils), the plenums, air filters… and everything in the air stream.
The cleaning of all air handling components is crucial to any air duct cleaning job. We can also replace worn insulation inside your HVAC units as needed, and often provide scheduled filter changes and maintenance.
We have some very detailed specification sheets that we have been using since we started back in 1987, and they are very similar to the NADCA spec sheets that are in existance today.
The photos above show a rooftop HVAC system that serves an air duct system that we recently cleaned in Markham, Ont. There are two shots of a rooftop exhaust fan that serves a dryer duct system that we recently cleaned in Mississauga. The second of those shots shows what a difference we have made afer having only blown off the lint with our high-pressure compressed air. That fan looked pretty amazing after we washed it too.
