Professional Air Duct Cleaning Services for Your Home
Comprehensive Duct Cleaning
We use industrial-strength tools and negative-pressure vacuums to thoroughly clean your ductwork. This approach allows us to extract dust, allergens, and buildup without spreading particles back into your home. With specialized rotary brushes and agitation tools, we scrub your ducts’ inner surfaces to remove debris that typical vacuums leave behind, ensuring a deeper clean throughout your HVAC system.
Vent and Register Cleaning
Our air duct service includes carefully removing, washing, and sanitizing your home’s vents and registers. These parts often collect dust that gets circulated each time your system runs. We clean not only the visible covers but also the surrounding duct openings to eliminate trapped particles. After sanitizing and drying each piece, we reinstall them securely to keep air moving efficiently through your home.
Furnace and Air Handler Cleaning
Your furnace and air handler work hand-in-hand with your duct system, which is why we take time to clean these key components. We remove buildup from areas like the blower, motor assembly, and heat exchanger—places that can reduce airflow and system output if left unchecked. Cleaning these areas helps your heating and cooling equipment function more smoothly and use energy more effectively.
Air Duct Repair Services
If we come across any issues like loose joints, leaks, or damaged sections during our inspection, we’ll take care of the necessary repairs. Our team handles resealing joints, reattaching disconnected sections, and replacing damaged duct parts. Ensuring your ducts are sealed and intact means better air delivery, improved efficiency, and less energy wasted in unused spaces.
Our Air Duct Cleaning Process
1
We begin with a complete inspection using advanced imaging tools to evaluate the interior of your ductwork. This includes checking supply and return ducts for visible buildup, mould, or damage that might impact airflow or require repair.
2
To protect your home during service, we cover nearby furniture and floors. Our technicians then open access points on the duct system and seal off other vents to maintain strong airflow during the cleaning. This setup improves system pressure and helps us clean each section thoroughly.
3
Using flexible rotary brushes and compressed air whips, we break apart dust, dirt, and debris from duct walls. We adjust our methods based on your duct material—whether it’s sheet metal, flexible ducting, or fibreglass—to deliver a thorough clean without causing damage.
4
The loosened debris is extracted using powerful vacuums that create negative pressure within the ducts. This process captures dust in a sealed container, preventing any material from escaping into your home’s air during service.
5
We also remove and deep-clean every accessible grille, vent, and register. Each piece is treated with a non-abrasive solution that lifts dirt and buildup. After cleaning, all components are properly reinstalled to restore your system’s flow.
6
We finish by cleaning the accessible parts of your air handler and furnace, including the fan blades, coil, and blower motor. Once complete, we inspect the full system to make sure all contaminants have been removed, and we reconnect everything to ensure your HVAC runs properly again.
