There are several common types of air ducts used in heating, ventilation and air conditioning (HVAC) systems in Ottawa area homes. Understanding the different kinds of ducts can help you make informed choices when it comes to maintenance and cleaning. Here are the main types:
Flexible Air Ducts
Flexible ducts are made of an insulated flexible metal or plastic material that allows them to be bent and maneuvered into place during installation. They are the most common type used in Ottawa homes due to their flexibility and ease of installation.
However, flexible ducts tend to accumulate more dust and debris over time since the internal material can trap contaminants. They require more frequent professional cleaning to maintain optimal performance.
Rigid Metal Air Ducts
Rigid metal ducts are cylindrical tubes made of galvanized steel that form a more permanent air distribution system. They generally last longer and often provide a tighter seal that reduces air leakage.
Metal rigid ducts usually perform more efficiently, but they are bulkier, harder to install and modify. Professional cleaning is needed less frequently (every 8-10 years) compared to flexible ducts.
Rigid Fiberglass Ducts
Rigid fiberglass ducts are somewhat less common in newer Ottawa homes. They consist of hardened fiberglass material formed into cylindrical tubes for air distribution.
Fiberglass ducts often maintain shape better over time, have less air leakage and require infrequent professional duct cleaning. However, they can be more difficult to install properly and repair if damaged.
ChooseDuct
ChoosDuct is a hybrid duct system that combines rigid and flexible components. The main trunk runs are often rigid metal with flexible duct take-offs that branch to individual rooms.
ChooseDuct systems aim to provide the best of both worlds – easier installation with flexible branches but better airflow and efficiency from rigid trunks. However, the flexible sections still accumulate more debris.
Hope this overview of common air duct types in Ottawa homes helps! Flexible ducts are by far the most prevalent, but each has pros, cons and slightly different cleaning and maintenance requirements to maximize HVAC performance.
