The Importance of Quality Ductwork for Central Air Installation

The design, installation, and condition of your ductwork are key players in how your home’s heating and central air systems perform. If you’re planning to update your HVAC and enhance your comfort, your ducting system is the first place to start. 

Below, we’ll discuss common ductwork problems in Edmonton homes, key factors in quality ductwork, and why you can count on our team at Weiss-Johnson for expert HVAC retrofitting and central air installation!

Common Ductwork Problems in Edmonton Homes

Many Edmontonians live in 20th-century houses, and if they haven’t been renovated in many years, their ductwork and HVAC system are likely outdated. 

Before you can successfully install a new furnace or air conditioner, it’s important to make sure that the unit you select is compatible with your ductwork (and vice versa). A certified HVAC specialist will assess the condition of your current ducting system to determine whether it needs to be renovated. 

Many older homes feature undersized ducts that are not compatible with modern furnaces and air conditioners. Ducts that are too small for a central air unit make it more difficult for hot and cold air to push through. This can reduce your HVAC’s lifespan while increasing your energy bills, as your furnace and AC work much harder to perform optimally. 


The restricted airflow from undersized ducts can also create temperature fluctuations throughout the house, causing some rooms to be too hot while others are too cold. Drastic temperature changes can also be the result of improper duct insulation, causing them to lose heat during winter and get too hot during the summer. 

Other common issues, such as air leakage, debris buildup, and outdated ducting materials, can all contribute to an inefficient system that is incompatible with modern, energy-efficient HVAC units.

Key Factors in Quality & Efficient Ductwork

The design, condition, and upkeep of your home’s ductwork all play a part in creating an updated and efficient central air system. With a quality assessment and retrofit from a trusted HVAC specialist, you can count on your ductwork to provide efficient temperature control and breathable air in your home.

Some key factors in achieving a quality HVAC system include:

Duct Size: Every home has different duct size requirements based on its layout and CFM standards. As a general rule, your HVAC system needs around 400 CFM (cubic feet per minute) per ton of cooling capacity for your AC or furnace to operate efficiently. 

If your ductwork needs resizing, we provide custom duct fabrication at Weiss-Johnson to ensure a perfect fit for your updated system!

Regular HVAC maintenance and duct cleaning: To maintain the quality and durability of your ductwork, it’s essential to stay on top of its upkeep. Furnace and AC ducts should be cleaned every 1-5 years by a certified technician. 

Our team at Weiss-Johnson uses the HyperVac H2, one of the most powerful vacuum systems and duct trucks in the industry. Don’t let your ductwork accumulate debris and compromise your home’s air quality—trust Weiss-Johnson to provide a deep and comprehensive duct cleaning.
