Furnace Duct Cleaning

An HVAC System (Heating, Ventilation and Air Conditioning) is what heats, cools and moves air around your home. The components of the system include:

• the furnace,
• the air ducts (ductwork),
• vents,
• heat exchanger,
• burner,
• registers,
• grilles,
• blower motor
• and fan.

• Furnace Cleaning
• Duct Cleaning

Furnace Cleaning - focuses on the internal elements of your forced air heating system. The furnace is cleaned together with other major parts such as the blower, fan, burner and heat exchanger. The objective is to remove dust and debris to improve efficiency and safety.

Duct Cleaning - involves removing dust, dirt, pet hair, foreign objects and allergens from the **ducts. (**Ducts can also be referred to as: air ducts, vents or air vents.) The whole system of ducts is generally referred to as ductwork. These terms are used interchangeably in the HVAC Industry. To expand further, the ductwork is a series of metal ducts or tunnels that provide a channel through which air flows, either to heat or cool the home.

Each room in the home will usually have one or two vents. More if it is a large room. The vents are the grids in the walls, ceilings or floors. These are situated at the opening of a duct for air to either be sucked in or out. The smaller vents are often referred to as hot air vents. However, that is not strictly the case. For example, when central air conditioning is available, those same vents provide cooler air to lower the temperature. The larger vents you see are the return air vents. As the name suggests, the air must be returned to the furnace or air conditioner.

Our professional HVAC cleaning begins with a brief inspection and assessment of your furnace and duct system to ensure a thorough and effective cleaning. Upon arrival, our technicians will review the scope of work with you and confirm they have clear access to all vents and the furnace. They’ll kindly ask you to secure any pets to ensure their safety during the service. As part of our safety protocol, the team will also complete a jobsite hazard assessment before work begins.

Our technicians will begin unloading the necessary equipment while carefully protecting your floors and walls using blankets and corner guards (also known as “ducs”). They will also switch to clean indoor footwear. One technician will start sealing off vents to prevent dust blowback and ensure optimal airflow pressure. Meanwhile, the second technician will assess or create access points near the furnace to attach the main vacuum hose. We employ the Push-Pull Negative Air Pressure Method for our furnace and air duct cleaning service, as recommended by the Qualified Air Duct Cleaners Association with whom we have membership.

• The air is compressed at 250 PSI.
• The Negative Air Pressure creates a high-powered pull to suck out all the dust and debris.

Before beginning the cleaning process, our technicians will turn off your HVAC system to ensure safety and prevent air circulation during service. They will also adjust your thermostat settings as needed to avoid the system turning back on prematurely. This helps maintain consistent airflow control and protects your equipment throughout the cleaning.

The duct cleaning technician will start the cleaning routine with the air duct vents furthest away from the furnace - usually on the top floor - and gradually work their way toward the furnace. As dust and debris are pulled from vents by the negative air pressure, other tools are used to push and agitate the dirt and grime simultaneously. The dirt will be forced into the main trunk line of the HVAC system. It is then sucked into the large, industrial-grade vacuum which is attached to the furnace by the cleaning technician at the outset of the furnace and vent cleaning procedure and the debris is subsequently removed from the home.

While one technician is working on cleaning the air ducts, the other technician is working in the furnace room cleaning the heating components. All contaminants are sucked into the powerful, industrial-grade vacuum connected to the furnace to ensure full-system extraction.

After the cleaning, your heating system will be turned back on, and a run test will be performed to ensure everything is functioning properly. If you have a smart thermostat, we’ll either adjust it for you or guide you through the process.

Once a comprehensive cleaning of all the elements of your heating system (mentioned in the section above) have been completed, our technicians will walk you through the work performed and conduct a vent count for the final bill – you only get charged for vents you have. All are cleaned. If any issues or observations came up during the cleaning, they’ll discuss them with you and offer recommendations where appropriate.

Choosing a qualified company is essential when it comes to duct cleaning. Inexperienced providers can unintentionally cause damage to your HVAC system, so it's important to work with a team that not only knows the industry but also stands behind their work and takes responsibility when issues arise.

It’s reasonable to be cautious about low prices—especially when it comes to home services. Phrases like “the $99.99 house special” are often mentioned because they can sometimes involve unexpected limitations or upselling.

We, too, would not necessarily recommend going with the cheapest, unless the cheapest is also the best. A very rare combination and probably not sustainable for a business over time.

We aim to keep our pricing transparent. Our base rate is $130 for one furnace and up to 5 vents. Additional vents—both hot and cold—are $10 each. A waste disposal fee (details in the footer) and GST also apply. More pricing information is on our Contact Page.

Some of our customers have shared that they were initially suspicious about our pricing, but after reading our reviews, decided to give us a try—and were glad they did.

See our Air Duct Cleaning Cost – Blog Post for a Comprehensive Look at pricing across different contractors.

It’s smart to clarify a company’s approach to upselling before committing to an appointment. Some companies may quote one price but then apply pressure to add extra services once they’re in your home. That’s not how we operate. While we may mention additional services that could be beneficial, they’re entirely optional. We respect your decision and never push for add-ons during the appointment.
