The following article applies to Air Duct Cleaning companies located in the province of Ontario, Canada but may also apply in your area, We suggest you check with your local authorities.
The cleaning that an Air Duct Cleaner can do on your furnace consists of cleaning any accessible components of the furnace that the air moves across, However, these same components must be cleaned while in place and under no circumstances are they to be removed or altered in any way.
Duct Cleaning companies are equipped with many unique proprietary tools that afford them the ability to clean the furnace's conveyance components while they remain in place.
I always make it a point to tell our customers that what we do on their furnace is no substitute for what a licensed Heating and Air conditioning Technician (HVAC Technician) will do on their furnace when it comes to doing an inspection and cleaning.
The law is very clear as to exactly what a Duct Cleaner is aloud to do on the furnace.
Duct cleaners are absolutely prohibited from doing anything in the combustion zone of your furnace, the combustion zone is the area that houses the Burners, Pilot light, Gas valves, Electrical components etc.
Any Duct cleaning technician that is messing around in that area of the furnace without proper certification is in serious violation of the law and will not be covered by their insurance company should anything go wrong.
We all too often hear from customers that tell us that SO & SO Duct Cleaning Company says that they will inspect the furnace as part of their Duct Cleaning.
If a Duct Cleaning company ever makes such a claim to you. . . I suggest that you stay far away from them, in fact they should be reported to the proper authorities.
The only exception would be if the Duct Cleaning company has a licensed Heating Ventilation and Air conditioning (HVAC) technician on staff who is doing the actual inspection or if they are bringing in a separate company that is HVAC Certified, in which case you would be wise to ask for proof of their qualifications.
