We recommend that you have your heating system cleaned every two (2) years. 

However, there might be specific factors in your home that may make more frequent cleaning necessary. Some of the most common ones are furry pets, new area construction, renovations, smoking in the home, or allergies or respiratory problems.

Frequent furnace and duct cleaning especially beneficial in homes with children or adults over the age of 65.

The cleaning system that we use is our own Multi-Zone TM cleaning method.  We maximize vacuum pressure and cleaning effectiveness by isolating the cold air side of the heating system from the hot air side during the cleaning process. In order to access these two parts of the system separately, we cut two 8” bypass holes – one above the heat exchange on the furnace for the hot air side and the other on the cold air plenum for the cold air side.

Next we connect the vacuum hose from our powerful custom designed truck mounted cleaning unit to each of the bypasses in turn, allowing us to use maximum suction at each vent and zone of the ductwork.  Using an exclusive, in-house developed tool called a Roto-Whip TM, we then clean each individual vent, the Roto-Whip TM provides full contact cleaning on the inside of the ductwork to loosen dust and debris, but unlike conventional contact methods such as brushing, it can’t damage or disturb dampers in the HVAC system which are essential to even airflow throughout the home.

We complete the ductwork cleaning by using the PredatorTM multi-headed whip to move dust and debris from he main plenums (section of the ductwork near the furnace) to our vacuum hose.

The same tool is then used on the heat exchange of the furnace to ensure a thorough cleaning down to the corners.  Last of all the blower is removed, air-washed and wiped down after which the parts are re-assembled before the system is tested.

Most cleanings will take approximately 45 minutes to 90 minutes.

Our technicians are trained in-house as per our cleaning expectations: however they are not gas fitters.  That is not a qualification that is needed to perform furnace cleaning and if you are in need of service, our service department would be able to help you.

Truck mounted units generate a better level of airflow; our units are powered by a large fan, which creates over 10,000 cubic feet per minute of airflow.  Our hoses are between 8 to 10 inches in diameter, in comparison to a normal vacuum hose, which is between 1.2 and 2 inches in diameter.  Our higher level of airflow allows us superior suction throughout your duct work to provide a more thorough cleaning.  Portable units cannot provide the same level of airflow that our truck mounted units do.   Tech’s carry about 120 feet in total of length.

In our research, we have found the whip system to provide “the best of both worlds” when it comes to cleaning.  With it we are able to get the full contact cleaning associated with brush cleaning, while offering the flexibility of pneumatic or high pressure air cleaning methods to get around elbows and past dampers that are in your ducts.

Our testing has shown us that brush systems can often close dampers, stop at elbows, and in older homes where the duct work may be more fragile, it can even cause it come apart.

We recommend that the furnace and ducts are cleaned together as it is a forced air circulating system.  That means that the air is moved not only through your vents and duct work, but through your furnace as well.

Cleaning one without the other would not be proper and would result in an incomplete and unsatisfactory job.  If only one is cleaned and not the other, once completed and the furnace is turned on again it will just recirculate the dust from the soiled area into the clean area.

Yes, we can do that as long as the furnace has been in for no longer than one week if not running and for less than a week if running.  This is called a furnace bypass.  The cost would be the same as it requires the same amount of work to bypass the furnace as it does to clean it.

We carry 125 feet in each truck.  That is the maximum amount of hose that we can use because after that you can reduce the amount of suction that you are able to clean with.


The reason that we charge for additional vents is because in general, more vents means a larger home and more time to clean.  If there are only 10 vents in a home it will usually take us between 35 – 55 minutes.  Since we use our Roto-Whip to clean each vent in your home, more vents will take longer to clean.

Additionally, the more vents the more duct work that we have to clean downstairs at the furnace.  When there are only 10 vents in a home the main duct work that must be cleaned is very short, but when there are more the duct work is much longer and takes more time to clean.

We must clean all of the vents attached to your system.  If we did not clean all the vents, dust and debris from the uncleaned vents would continue to circulate through your home and your heating system, finding its way back to your newly cleaned furnace and quickly diminishing the benefits of having the system cleaned at all.

The duct work for an individual is all connected so doing a partial cleaning of the system would not be fair to you as a customer.  We also fully guarantee our work, which is something that we could not do if we only cleaned part of the system.

You will need to count all your vents in your home including all the hot air vents and cold air return vents located on the walls.  Our technicians will go through the house and count the total number you have.


We use high pressure air to blow out each vacuum port and send anything which may be in the vacuum system down to the canister.  From there we clean out the canister, motor and filter.

We feed our high pressure airline through your dryer vent from outside of your home all the way to the back of the dryer.  A tool attached to the airline blows backwards forcing the line and dust back through the dryer vent and outside.

No, our high pressure tools can damage delicate components inside the dryer.


It all goes into the dust collector in the truck.  It is compacted like cement into the truck so we can carry quite large quantities.

Unfortunately you will not be able to see all of the dust that we remove from your heating system.  But if you ask the technician he can show you a large portion of it once it has been pushed to the furnace before it is removed from the house with the vacuum.

We have a set procedure which is designed to access 100% of your heating system.  We guarantee all of our work and will always come back for a follow up if you are not satisfied.

Yes, the results vary home to home depending on how dusty the home and neighborhood are, but it can significantly reduce dust levels.

While it is impossible to guarantee it, we have excellent results alleviating allergy suffering.  If you are bothered by dust, we find there is a notable reduction in the need to dust after having the furnace and ducts cleaned.

No, we take every precaution possible to send the dust into our truck not your home.  Sometimes when there is dust around a vent that can be stirred up while cleaning the vent but no additional dust will be sent throughout your home.


Our technicians will perform a thorough multi-point system check and recommend any service that needs to be performed.    Should you need to have service work completed we can book you an appointment with our service department.

There are anywhere from 10 to 25 points covered in our multi-point system check.  This depends on the type, style, features and age of the heating system.  It is a thorough inspection of the entire system.  Based on what the technician finds they will recommend any servicing that may need to be performed.

HRV stands for Heat Recovery Ventilator and its purpose is to maintain high indoor air quality without excess additional energy costs.  It does this by having two (2) separate air handling systems – one collects and exhausts stale indoor air; the other draws in outdoor air and distributes it through the home.  HRV are usually connected into the forced air heating system (this is the type of heating we use in Alberta) and we certainly do clean them.  They will have vents in several places in the home, sometimes only in washrooms and kitchens, other times they are in every room in the home.  They are typically located high on the wall and look similar to a cold air return grille.

When cleaning the HRV we must clean the unit itself, this is done by removing the heat exchange core and cleaning it as well as the fans connected to it.  We also must clean the vents throughout the home and we charge $9.95 for each of those.  The price for cleaning the HRV is $59.00.
