Professional Air Duct Cleaning Services for Your Home

Comprehensive Duct Cleaning

We use industrial-grade cleaning equipment to clear dust, dirt, and allergens from your home’s ductwork. Our vacuum systems create negative pressure inside the ducts, pulling out debris while keeping it from recirculating into your living spaces. With our rotary brushes and tools, we target buildup that can’t be reached with basic cleaning methods to ensure a thorough result.

Vent and Register Cleaning

As part of every service, we remove and clean all your home’s vents and registers. These areas collect layers of dust and particles that can re-enter the air during HVAC operation. We sanitize both the visible portions and the interior areas behind vents to ensure proper cleanliness. After cleaning, we reinstall everything securely to maintain system performance and airflow.

Furnace and Air Handler Cleaning

Cleaning key components of your furnace and air handler is a standard part of our service. We focus on parts such as the blower assembly, heat exchanger, and other areas that gather dirt over time and reduce performance if left untreated.

Air Duct Repair Services

During cleaning, we may uncover damaged ductwork sections that need attention. Our technicians are trained to seal leaks, reconnect loose joints, and replace worn-out segments. Ensuring the integrity of your ductwork helps minimize energy loss and ensures that conditioned air reaches each room effectively.

Our Air Duct Cleaning Process

1

We begin with a detailed inspection using specialized tools and cameras to examine your system’s return and supply ducts. This step helps us identify dust buildup, mould presence, or any structural damage that may require repair.

2

To protect your home, we cover nearby furniture and flooring and prepare the ductwork by creating proper access points and sealing unused vents. This process keeps cleaning efficient and prevents dust from spreading indoors.

3

Next, we dislodge stubborn debris inside your ducts using air whips and rotary brushes, carefully chosen for your specific duct material—whether metal, flexible, or fibreglass.

4

We then apply negative pressure through powerful vacuum systems to extract loosened contaminants from your ducts and into a sealed containment unit. This ensures particles are removed without escaping into your home.

5

All accessible vents, registers, and grilles are removed, cleaned with specialized solutions, and reinstalled to maintain proper air movement.

6

We also clean accessible components of your furnace or air handler, such as blower motors, evaporator coils, and heat exchangers, to support overall system cleanliness and operation.

7

Finally, we inspect your entire system again, reconnect any parts that were removed, and confirm that your HVAC system is functioning correctly post-cleaning.
