Professional Air Duct Cleaning Services for Your Home
Thorough Duct Cleaning
We use advanced equipment to clean your home’s entire duct network, removing allergens, dust, and other pollutants. With powerful vacuum systems that create negative pressure, we safely extract contaminants without spreading them. Specialized rotary brushes scrub the duct interiors, reaching areas that regular vacuums can’t.
Cleaning Vents and Registers
We remove, clean, and sanitize all vents and registers throughout your home. These components collect significant dust and debris, which can recirculate when your HVAC system is running. We clean both the front-facing surfaces and the inside edges behind the covers, then securely reinstall them to maintain airflow and cleanliness.
Furnace and Air Handler Service
We clean essential components such as the blower motor, heat exchanger, and air handler areas where dust accumulates. This detailed cleaning helps boost performance and extends your equipment’s life.
Air Duct Repair and Sealing
During cleaning, we inspect your ductwork for damage or leaks. Our technicians can perform on-the-spot repairs—sealing gaps, reconnecting loose duct sections, and replacing damaged parts. Proper sealing improves airflow and helps distribute clean air evenly across your home.
Our Air Duct Cleaning Process
1
We begin with a detailed inspection using specialized cameras and diagnostic tools to assess the condition of your supply and return ducts. Our team checks for buildup, mould, pest activity, or damage requiring repair or sealing.
2
To keep your home clean during service, we protect nearby floors and furniture. Vents not being serviced are sealed to maintain system pressure and prevent dust spread.
3
We then use rotating brushes and air whips to loosen dirt from all interior duct surfaces. Based on your duct material—whether metal, fiberglass, or flexible—we choose the safest tools for effective, damage-free cleaning.
4
A high-powered vacuum system is used to create negative pressure, pulling all loosened particles into a sealed collection unit—so nothing escapes into your living space.
5
All accessible vents, grilles, and registers are removed, scrubbed, and sanitized with specialized solutions before being reinstalled for proper airflow.
6
We also clean internal HVAC components such as the blower assembly, heat exchanger, and evaporator coil to maximize performance and improve air quality.
7
Before finishing, we complete a final inspection, reconnect all components, and confirm your HVAC system is functioning optimally.
