Frequently Asked Questions

We have a base price of $295.00 which includes 5 air vents. Each additional supply/return vent is $9.00 per vent and each cold air return vent is $9.00 per vent, so the final price depends on the total number of air vents in your home. There is a minimum charge of 10 vents. We clean all of the heating and cold air return air vents. The base price includes the cleaning of all of supply/return duct work and all components in the air stream (including furnace fan, air conditioning coil, furnace plenums, air filter, etc.). Our price includes all vacuum hook-ups to supply/return duct work required to do the complete job. If your home has two or more furnaces, there may be an additional charge of $125-$170 per furnace which depends on the location of the furnace. Otherwise, there are absolutely no hidden charges. The only thing extra is HST.

There is usually 1 vent per 100 square feet in your home. Please note that your final price will depend on the actual number of vents that our technician(s) counts while doing your home.

Our prices are a great value. When you consider the quality of work, you’ll agree we are hands-down the #1 choice for air duct cleaning in the GTA.

We use truck-mounted vacuum equipment and compressed air. Our technician runs a large vacuum hose from our truck to your furnace. Once the duct system is under suction, we clean each air vent with 250 psi of compressed air, starting on the top floor and working our way back down to the basement. This blows all the dirt from the air vents into the main ductwork. From there, we use air-snakes and air-whips to clean the main ductwork. The vacuum draws all of the dirt out to our truck. The procedure is repeated to clean the return air ductwork. All air-handling components are cleaned using compressed air.

Make sure the service provider has clear access to all duct openings and heating and air conditioning equipment.

We recommend this be done every 2 – 4 years in most cases. We have many customers who have us back annually, and some every two years like clockwork. If any member of your home suffers from asthma or allergies to dust then we recommend that you have your ducts cleaned more frequently. If you’ve recently completed renovations or are moving into a new home, then air duct cleaning is a must.

In most cases, no. We normally use this in cases where the customer has a definite odour coming from the ductwork. Also in cases where the homeowner has converted their heating system from oil to gas and had soot in the ductwork. What we use is actually a deodorant / sealant which becomes the new surface inside the ductwork. If even one tiny dust particle is left in the system after we’ve cleaned it, this will seal it in permanently. We’ve been using this product since day one with excellent results. There is a small extra charge for this if you require it.

We do not service the furnace itself, however we work with reputable companies who can.

Our list of services is extensive. If it has anything to do with your heating system, we probably do it. We do furnace cleanings / inspections, service work, gas piping, venting and air balancing. We install new gas furnaces, central air conditioning, air cleaners, humidifiers, complete duct systems or new heating vents.

We also do masonry cleaning and grafitti removal, heavy vacuuming and insulation removal.

Our service area is huge. We go as far west as Niagara Falls, to eastern parts of Ontario such as Cobourg, New Castle and as far north as Huntsville if the call arises.

When choosing an air duct cleaner, avoid making your decision solely on the basis of price. The quality of the job should be your highest priority, because quality will determine your savings in energy costs, comfort, and durability. Find out exactly what’s included in the job and what is not. The first thing that many of our prospective customers ask is the price. Some of our competitors do have a much lower “base price” or “hook-up” charge. But if they apply that price 3 or 4 times or more because they had to “hook-up” to your duct system that many times, then tell you that you should have them clean the furnace fan for only $ 49.00 while they’re there, etc., etc., then that “cheaper” price ends up costing you much more. It makes little sense to clean the air duct system without cleaning the furnace fan. Why would a reputable company leave it up to the customer to decide if they want to spend the extra money for that or not?

We also do service and cleaning on gas furnaces. Over the years, we have been to several homes to clean the furnace just after a duct cleaner left. Sure they came and made some noise for twenty minutes, but they didn’t clean the furnace fan, or the fan compartment, and obviously didn’t even take the door off the furnace. If they weren’t going to clean the air filter, they could have at least told the customer to replace it. When asked why they didn’t do any of these things, their excuse is “Well, we’re duct cleaners not furnace technicians”.

At City Duct Cleaning Inc., we clean everything in the airstream, and it’s always included in the job.

Our base price applies only once.
