Professional Air Duct Cleaning Services for Your Home
Comprehensive Duct Cleaning
We use commercial-grade cleaning systems designed to thoroughly clean your air ducts and remove debris that has built up over time. Our vacuum system creates negative pressure within your ducts to pull out particles without allowing them to circulate back into your home. Specialized rotary brushes and agitation tools are used to loosen dirt and buildup, even in hard-to-reach corners of your ductwork.
Vent and Register Cleaning
Dust and debris often collect inside vents and registers, impacting both airflow and air quality. As part of our complete service, we carefully remove and sanitize these components, reaching behind vent covers to clean out accumulated particles. Once cleaned, we reinstall everything securely to ensure your HVAC system delivers consistent airflow throughout the house.
Furnace and Air Handler Cleaning
Key HVAC components like your furnace and air handler can also collect dust, reducing efficiency. Our technicians clean inside these units, including blower fans and heat exchangers, helping your system run smoother and reducing strain on parts.
Air Duct Repair Services
During your duct cleaning, our team may spot areas that require repair, such as leaks or disconnected sections. We carry out professional duct repairs on the spot—sealing gaps, reconnecting loose segments, and replacing damaged parts as needed. Ensuring your ducts are properly sealed and connected helps improve airflow and reduces energy loss.
Our Air Duct Cleaning Process
1
Every duct cleaning service begins with a detailed inspection. Our technicians use tools and video equipment to inspect your return and supply ducts, checking for buildup, mould, and physical damage that may require repair.
2
Before cleaning, we take steps to protect your home. Furniture and floors near the work area are covered, and we isolate the sections of ductwork we’re cleaning to keep pressure balanced during the service.
3
We use a combination of compressed air tools, rotary brushes, and air whips to loosen debris from the inside walls of your duct system. Based on your ductwork type—whether metal, flex, or fibreglass—we select the proper tools to ensure safe and thorough cleaning.
4
Our high-powered vacuum system then creates negative pressure throughout the ducts, pulling out the loosened particles. This process ensures all dirt is removed from your system and collected without spreading dust inside your home.
5
We also remove and deep-clean all accessible vents and grilles throughout the house. These components are cleaned using specialized solutions that eliminate grime, dust, and buildup. Once done, they are carefully reinstalled for optimal airflow.
6
In addition, we clean accessible areas of your furnace and air handler, such as the motor, coil, and interior components, to help your heating and cooling system run more effectively.
7
Finally, we complete a thorough inspection to confirm that the duct system has been properly cleaned. We reattach any parts removed during the process and ensure your HVAC system is ready to operate efficiently.
