The Importance of furnace filter changes


duct cleaning toronto


As we get ready for winter, there are many things to do in the yard as well as in the house.  One of the important tasks that is often overlooked is replacing the furnace filter.  The main purpose of a furnace filter is to protect the blower fan and equipment  from all the dust, hair and other gunk the return duct pulls in.


Why is it so important? Here are five benefits of regularly replacing your air filter:


  • Extend the life of your forced air system – a big investment was made when you purchased your HVAC equipment.  One of the main reasons a HVAC systems fails is because the furnace filter gets plugged up with debris and particulate matter . As dirt accumulates, air can’t pass through the system  and the unit overheats. The motor then has to work harder. In a best-case scenario, your HVAC unit will need to be repaired. In the worst case, if your unit is older, not replacing filters could put it over the edge and require you to buy a new one. Replacing the filter is an easy way to lengthen the life of your heating system.
  • Keeping energy costs under control – lets face it, getting your utility  bill is not the highlight of your month. When that air filter is plugged ,little air passes through the filter which makes the HVAC system work harder, more energy is being used. And when it requires more energy to make your heating and air conditioning system work, it causes your energy bill to escalate .
  • Maintaining healthy air quality in your home – This is particularly important if anyone in your family suffers from allergies or asthma. Dirty air filters worsen the air quality and can worsen symptoms. Replacing your furnace filter is an easy way to help improve the indoor air quality in the home .
  • Keeping your HVAC system clean – Dirty filters in the furnace can lead to dirt build up on fan which reduces air flow.  It can also contribute to the AC coils in the furnace to become plugged up. When this happens the air flow is greatly restricted.
  • A peace of mind – Replacing your furnace  filter is an easy, inexpensive step to take to save money, extend the life of your HVAC equipment and improve your IAQ in your home or business. It also decreases the amount of your energy consumption .

Air Make Up Systems

Call Power Vac Winnipeg for your Commercial Duct Cleaning Needs


This video will show how a standard make-up air ventilation system works and the benefits of preventive maintenance on this
critical system in your building. You will see a professional tradesperson carry out a typical preventative maintenance call,
as well as some simple tasks that your staff can perform to keep your make up air unit running properly.

Let our HVAC inspectors conduct a comprehensive examinations of components and systems to determine whether they are
contaminated with a significant accumulation of particulate or microbial growth, or if HVAC performance is compromised
due to contamination build-up.

PREVENTION of duct contamination is KEY to avoiding problems.
Follow these recommendations to avoid system contamination:

•Perform routine preventive maintenance on HVAC
systems, by complying with manufacturer schedules
for changing HVAC filters, cleaning coils, and other

•During building renovation, seal ductwork to prevent
construction dust and debris from entering the HVAC

•Maintain good housekeeping in occupied spaces.

•Ensure that air intakes are located away from
contaminant sources.

•Consider routine inspections of ductwork. The National
Air Duct Cleaning Association (NADCA)’s standard,
“Assessment, Cleaning and Restoration of HVAC Systems-
ACR 2013,” recommends that HVAC systems be visually
inspected for cleanliness at regular intervals, depending
on building use. For healthcare facilities, the standard
recommends annual inspections of air handling units
and supply/return ductwork

Fresh air makeup system



Makeup air units- What every condo owner should know

Make-up air units supply fresh air to buildings to compensate for air lost through exhaust fans and other sources. Simply put,
they “make up” for lost air, which helps to ensure good indoor air quality for everyone.

With 48 years of service excellence in the condominium marketplace, the Power Vac Cleaning team has the experience to properly
address and complete any commercial residence job. This means cleaning spaces shared by all tenants, including hallway air
make-up systems and, especially, laundry exhausts — an area often prone to fire hazards due to the materials that build up
inside of high-use dryer vents. Cleaning such areas on a regular basis helps reduce costly repairs and improves the efficiency
and lifespan of your building’s equipment.

High Tech Furnace Filter

Your Air Filter Just Got Smarter


Wouldn’t it be great if your air filter could send you a text
when it became clogged and lost its efficiency?

For many of us, changing air filters is an easily forgettable chore.

Who has time to think about something that is hardly noticed on a daily, or even weekly, basis? Typically, central air conditioning and heating system filters are changed randomly or when it “feels” right.

A new air filter monitor removes this guesswork by sending an email or text alert to your smartphone, tablet or desktop computer when the filter becomes clogged so you can enjoy cleaner air, lower electric bills and an efficiently operating HVAC system.

And, it’s not just convenient. Regular filter changes can help save $300 annually.

Just like your automobile’s gas gauge, the CleanAlert FILTERSCAN WiFi shows how much ‘cleaning power’ remains in your home’s air filter. The monitor continuously tracks the condition of your home’s air filter, and the AirFilterSentry™ Notification Service instantly alerts you of an efficiency-robbing clog. This way, you or your HVAC contractor know exactly when your air filter needs to be replaced.

Theres a Raccoon in my ductwork

In our 48 years of duct cleaning, this one will make the hall of fame

Power Vac Toronto received a call from a customer who was complaining about a bad odor coming from the ventilation system.   We regularly received call from clients about bad smells and sometimes we find dead mice, squirrels, snakes  etc but our service tech was not ready for this one

What we found was unbelievable . The smell was unimaginable . The Power Vac service tech persisted and removed the dead animal from the ductwork . We never did find out how the wild animal was able to get into the ventilation system.
