When consumers think about HVAC, they generally envision the furnace, AC, or heat pump. But here's the reality: without effective ductwork, even the highest-tech system won't provide the comfort it pledges.

Here at Airtek, we install through contractors and dealers throughout Canada, and we've seen it again and again—ductwork ruptures or ruins an install. If the airflow is improper, the system will not work, the customer won't be happy, and you'll be stuck with callbacks.

Why Ductwork Matters More Than You Think

Think of ductwork as the highway for air. If the road is too small, contains too many turns, or is riddled with potholes (Leaks), traffic grinds to a halt. Same as air. Bad ductwork = uneven temps, higher bills, and undue wear on equipment.

Good ductwork, on the other hand, equals:

Same temperatures throughout every room

Lower bills

Quieter systems

Happier customers

Common Ductwork Mistakes to Avoid

Even professionals err occasionally. The following are the most typical ductwork problems we find:

Undersized ducts – restrict airflow and overwork the system

Oversized ducts – air moves too slowly and reduces comfort

Too many turns – every turn adds resistance and lowers efficiency

Leaky joints – energy (and money) literally pumping into thin air

Not enough returns – below-par air flow that leaves customers frustrated

The Payoff of Getting It Right

When ductwork is properly done, it's a win-win for all:

Comfort: No hotspots and cold spots—just consistent temps.

Efficiency: The system is not working overtime, which saves money.

Longevity: The equipment takes less abuse, so there are fewer breakdowns.

Quiet operation: Customers love their system operating smoothly and quietly.

Fewer callbacks: Less time fixing mistakes, more time on new installs.

Best Practices for Contractors

Desire to eliminate the normal headaches? Follow these basics:

Perform a Manual D calculation for sizing each time.

Seal and insulate ducts against leaks.

Keep straight runs and eliminate sharp turns.

Provide ample return air.

Utilize quality materials and fittings to maximize airflow.
