Furnace & Duct Cleaning

Relying on professional equipment and practiced techniques, KnRs handles furnace and duct cleaning. Clearing out your ductwork provides cleaner, healthier air for you and your family. Our procedures take roughly 2 to 3 hours. We use high powered trucks along with the PowerWhip to clean your ductwork and HVAC system. The PowerWhip technique scrubs the entire duct system with latex whips– a great process for older or recently renovated homes.

We do not have any hidden costs, nor do we charge by the vents.

Dryer Vent Cleaning

Neglecting to clean your dryer vents could lead to fire. According to the Consumer Product Safety Commission, an estimated 15,000 dryer related fires occur every year. These types of fires have caused around 97 million dollars in property loss for homeowners.

Clogged dryer vent pipes can cause your machine to work harder, increasing the time it takes to dry clothes and as a result raise your energy bill.

Results Guaranteed!

A clean dryer vent is important for protecting your home against fires. That’s why we rely only on certified technicians with specialized equipment to thoroughly clean your entire vent duct exhaust line. We remove lint buildup, working from the dryer to the exterior exhaust vent hood. We get your dryer operating at peak efficiency so that you can reap the immediate benefits. Reduce drying time, save energy, reduce fire hazards, and expand the overall lifespan of your dryer with regular dryer vent cleaning.

Ongoing Maintenance

Clean your dryer vent, furnace, and ductwork every 3-5 years to ensure optimal air flow, sanitization, hazard reductions, and optimal performance.

Signs of a Plugged Dryer Vent

A dryer vent might be plugged up if your dryer keeps shutting off earlier or before the dry cycle ends. If your clothing feels hotter than normal at the end of the cycle, this could be an indication that your dryer vent is clogged. All in all, a clogged dryer vent means your clothes take longer to dry. Additionally, the flapper on the outside vent hood might not open when the dryer is on. Check for these signs to see if your dryer vent needs cleaning.

Frequently Asked Questions

How do you clean the furnace?

First, the technician will bring you down to the furnace room and explain how your particular system works. He will then do a 20-point mechanical inspection of your heating system and other components, such as the hot water tank, fireplaces, and belts. He then will prepare the system for cleaning. A large 10″ vacuum hose will be brought down to the furnace room, connecting the ductwork to our powerful truck mounted vacuum. A high-pressure airline (1″ diameter) is then run from the truck, into the house for use in the cleaning. At this point the ductwork in the house is sealed off, to optimize vacuum pressure and to prevent any back drafting of dust. After the vacuum is turned on, each branch of the ductwork is individually cleaned using highly compressed air through a forward skipper and a wand. We customize each cleaning to meet the needs of your particular duct system, using several different pieces of air equipment. Downstairs, the main part of the ductwork is cleaned out using a powerwhip to ensure that even the heaviest debris is removed. This device can be described as an octopus with tentacles. After the duct cleaning is done, the furnace is cleaned from top to bottom, including the heat exchangers,the blower, the burner tubes and the air conditioning coil if applicable.

Why clean a brand new home?

When a home is built, the first thing to be installed after framing and exterior sheathing has been completed is your heating and ventilation system.

All of the sub-contractors such as plumbers, electricians, dry-wallers, and finishing carpenters start their work after the duct system is in place.

These trades leave behind things like sawdust, wood chips, drywall plaster and dust, and any other items that may have been used in construction.

Unfortunately, homebuilders do not always have the duct systems cleaned out after all construction is completed. On top of this, newer areas have far more dust because of their vicinity to farmland and heavy equipment used in the construction of the community.

For these reasons, it is most important that heating and ventilation systems are cleaned out after a new home is built.

How much air pressure do you use?

The air pressure used is 300 p.s.i. (pounds per square inch), which is more than twice that of a regular car wash wand.

What is the size of your vacuum hose?

The hose diameter is 10”.

What is included in your 20-point air quality inspection?

Blower & blower hardware
Summer switch
Flue/gas utility chimney
Wood fireplace chimney
Hot water tank
Dryer vent
Return air ducts

Will the access hole affect how my furnace works?

No, not at all, the access hole is cut above the furnace in the plenum to prevent debris from unnecessarily going into the furnace. Once the cleaning is complete the hole is professionally sealed with a 10” x 10” sheet metal plate. This is an airtight seal so there will be no loss of efficiency in your heating system. For future cleanings we will be able to remove the existing plate and reuse the same access hole.

Is there anything I need to do before the cleaning?

The only thing that you need to do is ensure that there is enough room around the furnace for the technician to work. The technician can move any furniture that needs to be moved, unless you would prefer to do it. As a precaution, if it is a cold day you may want to move any plants away from your entrance-way.

How do we access the home?

We access your home through a door or window. Our large vacuum hose (10″ in diameter) will need to reach the furnace area from our vacuum truck. A high-pressure airline also needs to extend from our vacuum truck to all areas in the house that have air registers (both hot and cold).

Access is to be determined by the technicians at the time of cleaning.

In cold weather, we do everything possible to ensure the house does not cool down more than a few degrees.

Even on the coldest of days, (we work when the weather is above -25°C) we find that most of the houses we are cleaning do not drop more than a few degrees overall.

When is the best time of year to get my furnace and duct cleaned?

There is no bad time, but better times. Most think of using our services in the fall, as our customers experience the first smell of the “stinking furnace air.” You will experience a longer booking time then. We recommend, getting it done right now. Why put off breathing the healthy, clean air that your family and you deserve today!

What is your vacuum suction?

Vacuum suction is 13,000-15,000 C.F.M. (Cubic Feet of Air Movement per minute). The C.F.M. at the fan base is 40,000, but because we rate vacuum suction at the furnace, or at the end of our hose, it is lower.

What kind of equipment do you use?

We use truck mounted (as opposed to portable) equipment.

What is your guarantee?

Experienced, qualified technicians will provide friendly and competent service, using state of the art truck mounted cleaning technology.

Will the cleaning create dust in my home?

The cleaning itself will not create dust; however because a door or window must be open during the cleaning to allow air back into the house, the dust that is in the outside air may settle in the house once the equipment is turned off. (No more dust will come in from outside than if you left your windows open in the summer.) The only other area dust may settle after the cleaning is in an unfinished basement. The exposed ducts in the basement may have dust on top of them and this dust may shake off during the cleaning because the ducts vibrate. As a precaution you may want to cover any computer equipment you have in an unfinished area due to the fact that a computer attracts dust.

Do you charge for travelling outside the city?

Yes, we do depending on where you live (please contact our office for your rate). If we are able to book more than one cleaning call in your area, then the travel charge would be reduced.
