What Steps Are Involved When I Have My Ducts And Furnace Cleaned?

When you call a duct cleaning company for service, it’s good to know what will happen from the time they arrive until the time they leave. Duct and furnace cleaning is an important part of home maintenance, and professional cleaning companies should have a professional process and quality service. Here’s what you can expect from a reputable service provider.

Arrival and set up

When the team arrives for the appointment, they’ll likely introduce themselves and walk you through the service process and method. This is a good time to review the scope of work and the quote to make sure they’re going to do what they’re supposed to do – and to confirm there won’t be any unexpected charges.

They should lay drop cloths under the vacuum hose so it doesn’t leave a mess or damage your floors or walls. The hose will generally enter your home through a basement window or the main entranceway, and go down to the furnace.

At this stage, the team will also go through your house to confirm that the quote accurately reflects the number of ducts in your home, and put magnets over each air supply vent (register). A duct mask will be placed on the return air vents. This prevents dust and debris from getting into your home and improves vacuum suction.

Furnace check

Once they have set up their equipment and explained the process to you, the service team will begin with a general furnace checkup. This typically includes looking at the ignition, inducer motor, and blower motor, and ensuring everything is operating properly. If your furnace is equipped with a humidifier or UV light, these should be looked at too. The thermostat will be lowered and the furnace will be turned off.

Duct and furnace cleaning

After a thorough furnace inspection has been done, the duct and furnace cleaning begins. They will connect the vacuum, clean supply runs, and main supply ductwork​ and clean the supply heat runs and main ducts as well as furnace doors and cabinets.

Most companies will also blow out your hot water tank burners as part of their service (they will need to turn off the pilot light and relight it once they’re done.

You can tell you’ve selected a good company if they take the time to remove the blower motor and assembly from your furnace before they begin cleaning. This step requires well-trained technicians, but will always result in a cleaner furnace.

Furnace filter replacement

Once cleaning is done, a new furnace filter will be installed.

There are a variety of different filters available. Most duct cleaning companies will replace your filter with a simple fiberglass model instead of an expensive name-brand filter. You may be surprised to learn that a basic filter is actually easier on the furnace and offers sufficient filtration, provided it is changed at regular monthly intervals. Heavy-duty filters provide more airflow resistance, which can cause a furnace to overheat if not properly monitored.

Permanent reusable filters are made from solid aluminum and are more durable than other options available, and also the most expensive. If you have this type of filter, the technician should clean it for you.

Review, report and reschedule

Once cleaning is done, the team will turn the furnace on and reset your thermostat. They’ll gather their equipment and drop cloths, and apply a sticker furnace, which will include your next date of service. At Advanpro, we go the extra step of including the numbers of vents cleaned, so the information is handy for future reference).  Each tech signs his or her name, as a sign that they stand behind their work!

At this point, they may report the work they did and answer any questions. As part of our process, Advanpro provides customers with a Duct and Furnace Cleaning Checklist. It shows everything they did and notes any issue that should be addressed or monitored moving forward (like noisy blower motor or leaking condensate trap etc.)

Beyond our experience and professional service, Advanpro prides itself on being a customer advocate. We’re here to advise, educate, and help you make the best decision for your home.

A/C Tune Up

Regular preventative maintenance improves efficiency and extends the lifespan of your air conditioning system, with the following benefits:


  • Reduced electricity bills and operating costs. When the unit operates as designed, electricity usage is reduced.
  • Maximized cooling capacity. Home comfort on the hottest of days with minimum run time.
  • Minimized repair bills. Detect and fix small problems before they get worse.

HRV Cleaning

In Calgary, all homes built in 2016 or later have a Heat Recovery Ventilator (HRV). Some homes built or renovated after 2013 may also have an HRV. 


An HRV efficiently replaces stale indoor air with fresh outdoor air, all year round.


As with any other air-handling equipment in your home, your HRV should be cleaned regularly to ensure the best possible indoor air quality.


If you aren’t sure if you have an HRV, call our team to find out how you can tell.

Duct Work Sanitizing

If you or your loved ones suffer from respiratory issues or allergies, or you’re concerned about the quality of the air that you are breathing, then our sanitizing treatment will give you the reassurance that your ductwork is sterile and free of debris that could negatively impact your respiratory and overall health.


Microban is our hospital-grade sanitizing solution, which kills 99.99% of germs, viruses, funguses, molds, and other pathogens.


We also offer Benefect, an all-natural sanitizer made from plant extracts, which also kills 99.99% of germs, viruses, funguses, and molds. ​

Exhaust Flu Stack Cleaning

Mid-efficiency furnaces produce a sand-like, mildly-corrosive byproduct. This substance condenses in the exhaust flu stack and collects over time near the inducer/venter motor, restricting exhaust gas flow. Eventually, it enters the inducer motor and causes premature wear on the furnace.


Exhaust flu stack cleaning removes the build-up to reduce the chance of motor failure and maximize the life span of your furnace. Preventative maintenance ensures your furnace runs efficiently all Winter long — without costly no-heat emergencies. 

A/C + High-efficiency Bypass

The secondary heat exchanger in a high-efficiency furnace or A/C coil has delicate, closely spaced fins that must be protected during your furnace and duct cleaning.


For furnaces that require a bypass, we temporarily install a filter above the heat exchanger or A/C coil, and position our duct vacuum above the filter.


This bypass procedure prevents damage by ensuring all dust and debris in your supply duct work is collected before reaching the heat exchanger or A/C coil.


Standard furnaces without A/C don’t have secondary heat exchangers or A/C coils and don’t require the bypass procedure.

Furnace Tune Up

Regular furnace tune ups are essential to maximizing the lifespan and efficiency of your furnace, so you can rely on it to keep you warm all Winter long.​


During our 30+ point inspection, we check all furnace systems to identify components that are worn out and need replacement. Replacing parts before they break — preventative maintenance — maximizes heating efficiency, avoids no-heat emergencies, and saves on costly service calls. 


Home furnaces can last for 20 years or more if well-maintained. A professional furnace tune up every two years helps to preserve your investment for decades.

Reverse Octopus Whip Tool

The reverse octopus whip has eight 16” flexible tentacles, which whip around blasting high-pressure air in all directions as it moves through your duct work.


The tool agitates and dislodges the most hard-to-reach dust, debris, and contaminants, moving them toward our duct vacuum for collection and disposal.

Brush Cleaning Method

Our high-speed rotary brushing equipment sweeps the entire interior surface of your duct work, ensuring that all dust, debris, and pet hair are vacuumed away.


Physically cleaning the entire length of your duct work ensures that no contaminants are left behind, increasing your indoor air quality and peace of mind.

Dryer Vent Cleaning

Dryer fires are a top-five cause of house fires. Cleaning your dryer vent regularly greatly reduces the chance of a dryer fire, plus the following benefits:


  • Reduces clothes drying times
  • Lowers utility bills through greater efficiency
  • Extends the life span of your dryer
  • Lessens the amount of allergens in your house

Back Skipper Tool

The back skipper is a 1” diameter rounded ball connected to a long, flexible high-pressure airline.


The 1” ball has jets that discharge high-pressure air, pulling the tool and airline through the length of your duct work.


The high-pressure air moves the dust and debris toward our duct vacuum, where it is collected for disposal.​
