How Ductwork Affects HVAC Efficiency, Comfort & Equipment Sizing | Airflow Explained | Ep. 3

Your furnace or heat pump can only work as well as the ductwork supporting it. In *Episode 3 of our 4-part HVAC Education Series*, Owen Wamboldt, owner of Wamboldt Heating and Air Conditioning, breaks down how ductwork affects airflow, equipment efficiency, comfort, and noise levels throughout your home.

Whether you're upgrading to a high-efficiency furnace, switching to a heat pump, or wondering why one room is always hotter or colder than the others, this episode will help you understand why proper duct sizing and layout are critical.

🔍 *What You’ll Learn in This Video:*
* How ductwork impacts equipment performance and energy use
* What supply and return air ducts actually do
* How duct size and layout affect airflow, noise, and comfort
* Why poorly designed ducts lead to overheating, loud systems, and uneven rooms
* How new equipment (especially heat pumps and full electric systems) can strain old ductwork
* What CFM (cubic feet per minute) means for airflow
* Real-world examples of common Ottawa ductwork problems
* What to do about cold bedrooms over garages
* Why your furnace gets louder when the filter is dirty
* The benefits of zoned duct systems for multi-floor comfort

🛠️ *Key Topics Covered:*
✅ Return air vs. supply air ducts
✅ Older homes in Ottawa with limited return air pathways
✅ Upgrading from PSC motors to variable speed motors
✅ Why new high-efficiency equipment demands better duct design
✅ How to plan ductwork for heat pumps (spoiler: you can’t just swap them in!)
✅ When to consider duct redesigns or zoning systems in custom builds

💨* Does Your Furnace Sound Louder Lately?*
If your ductwork isn’t sized to match your equipment, your variable-speed motor may be ramping up to compensate for airflow restrictions—especially with a clogged filter. Owen explains what’s happening and how to prevent comfort issues.
