9 Questions To Ask When Choosing A Furnace And Duct Cleaning Company

When it comes to choosing a duct cleaning company, information is power. The more you know about the services you need, the more informed you’ll be when it comes to selecting the right company to work with. You’ll be happier with the end result too. Here are some good questions you should ask when on the hunt for a professional duct cleaning company in Calgary.

1. How many vents are included?

Most duct cleaning companies charge based on the number of vents (or registers) connected to a furnace’s ductwork. This includes both the supply vents and returns air vents.

Make sure you ask how many vents are included in the advertised price and have the company outline the number in their quote. You’ll also want to find out what the cost is for each additional vent.

Tip: When counting the vents in your home, it helps to go room-by-room. Some rooms may have multiple vents. Be sure to look for vents behind or under furniture. In bathrooms, some heat registers are hidden on the sink cabinet base, just below the cabinet door. In the basement, be sure to look up: vents are often located on the ceiling! You do not need to include the bathroom exhaust fan/vent, as these are not part of the cleaning process.

2. Is the quote is all-in are there additional fees?

While the service company will rely on you to provide an accurate vent count, ensure they are upfront about any remaining costs so that there are no surprises when it’s time to pay.

Some providers will give you a lowball estimate to get your business, but then tack on “environmental fees” or “disposal charges” when it’s time to pay. So what seemed like a deal at the time isn’t really that much different from the price of a more reputable provider.

3. What type of cleaning equipment do they use?

A reputable duct cleaning company will have a specialized truck and professional equipment that ensures a quality job is done. There are a few different cleaning methods, however, the best ones involve a High-pressure Air Blow Gun and/or a High-speed Rotary Brush.

Find out if they use these methods, and if they don’t it’s a red flag. At Advanpro, our High-pressure Air Blow Gun and High Speed Rotary brush methods ensure we are able to provide our customers with the most effective cleaning option based on their budget. Our Silver Package uses the High-pressure Air Gun, and our Platinum Package uses the High-Speed Rotary Brush, followed by the High-pressure Air Gun.

4. Are their vacuums truck-mounted or portable?

If a company shows up to your home with a portable vacuum unit to collect dust and debris from your furnace and ductwork, it should set off alarm bells. Professional companies that specialize in duct cleaning use dedicated, built-for-purpose vacuum trucks. These trucks are designed to safely and efficiently draw and collect high-volumes of dust and debris from your duct system. Advanpro’s truck-mounted vacuums are capable of moving up to 9,000 cubic feet of air per minute!

Portable units will not provide adequate suction to do the job properly – and are a sure sign of a company that is not investing in their business or their customers.

5. Do they offer flexible scheduling and fixed appointment times?

You have a busy schedule and want appointments that are convenient for you and your family.  A customer service driven company should offer flexible appointment times, including evenings and weekends.

Choose a company that values your time, and will commit to promptly showing up at a specified time – instead of asking to wait for them to arrive at some point within a 5-hour window. (This is an aspect of Advanpro’s service that our busy customers truly appreciate.)

6. What’s involved with the furnace cleaning?

Make sure that the price includes a furnace cleaning. This should include a cleaning of the furnace cabinet, blower motor, and all other components – even the furnace doors. Ask if the price includes replacing the furnace filter.

At Advanpro, we go the extra step to remove the blower motor and assembly from your furnace to ensure more complete cleaning. Not all companies do this, as it takes time and can be difficult for inexperienced technicians.

If you have a high-efficiency furnace, the cleaning company will need to take additional steps to protect sensitive components. Advanpro offers a Bypass procedure. This added measure ensures that all dust and debris in your supply ductwork is collected before it enters your delicate Secondary Heat Exchanger (or A/C coil), where it can cause damage.

7. Can they clean your dryer vent while they’re at your home?

If you’re going to have your ducts cleaned, it’s always a good idea to bundle in additional services that you may need, including dryer vent cleaning. Ask if dryer vent cleaning is included in the price.

If it’s not, find out how much it is to add it to your quote. You can also ask about incentives to add in other services, maintenance work, or repairs. At Advanpro, we have three unique packages, and the Platinum and Ultimate Total Care packages both include dryer vent cleaning. It’s a great value-add for the client, and important service too.

What is dryer vent cleaning? Dryer vents are not connected to the furnace. Their job is to allow the air from your clothes dryer to exhaust outside. Lint can build up in the vent and in the dryer, and in some cases has been known to cause fires due to the heat generated by the dryer. Advanpro includes ground-floor dryer vent cleaning with our Platinum and Ultimate Total Care packages.

8. Do they offer value-added package deals?

If you’re looking for more comprehensive service, find out if they have value-add packages instead of single-service (a la carte) options. As a customer, it’s nice to be able to select or customize a package that works for you and will help you save a few bucks. Some great value-add services include furnace tune ups, A/C tune-ups, dryer vent cleaning, and bypass cleaning for high-efficiency furnaces. A professional company should also be able to advise you on which additional services you’d benefit based on your furnace and your home.

9. Do they guarantee their quotes?

No one likes surprises. There’s nothing more frustrating than being quoted one price and being billed another once the work is done. Confirm that the price you’re quoted is the price you’ll pay.

At Advanpro, we guarantee our quoted price. You just have to answer a few questions. This can be done online using our Online Duct Cleaning Quote Calculator, or by calling an Advanpro customer service representative 403-873-7779.

Do your research, review several companies, and select the one that offers the most professional services and great value. You and your home deserve it! Read more about duct & vent cleaning here.

Furnace & Duct Cleaning Checklist

When we receive an online furnace or air conditioning quote request and the customer accepts the initial quote, we’ll send a comfort advisor to confirm the provided information and quoted price in person. 


If the comfort advisor finds any inaccuracies during the in person visit, we’ll revise the quoted price on the spot. After the quoted price is confirmed with an in person visit, the price is set. 


If there are unforeseen complications on the date of install, Advanpro will not pass the additional costs along to the customer. (See exceptions in Terms below.)



The guarantee is not valid if the customer provides inaccurate information when Advanpro seeks to confirm any information about the quote. This also applies to the on-site confirmation visit. 



In the exceptional circumstance that the chimney liner required for most furnace installations cannot be installed or gets stuck during installation, the guarantee no longer applies and we will provide a supplementary quote to complete installation. 


We do not warranty or guarantee customer-supplied thermostats.

Repair guarantee

If the diagnosed issue is not fixed by our initial repair, we will dispatch the first available service technician to return and fix it at no additional cost.


If we determine that there is an additional unrelated issue, there may be a charge for the additional repair.

Advanpro must be immediately notified of any install issues. The guarantee applies for 3 months, starting from the installation date. The guarantee no longer applies if, at any time after the quote or installation, modifications are made to the home that impact heating requirements.

Hot water tank types

Natural draft or atmospheric vented hot water tanks have a 3″ – 4″ steel vent pipe, which runs to a vertical chimney. The chimney is usually shared with standard or mid-efficiency furnaces.


Power vented hot water tanks have one or two black or white plastic vent pipe(s), which are 2″ – 3″ in diameter. The vent pipes usually exit from the side of the house.

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.​
