The Truth About Prefab vs. Custom: Not All Metal Is Created Equal—And Your Comfort Knows the Difference
You might not think much about the ductwork running behind your walls and ceilings—but when it comes to comfort, efficiency, and even your energy bills, it’s the unsung hero (or secret culprit) of your HVAC system. At Christiansen Heating & Sheet Metal, we’ve seen firsthand how the choice between prefab and custom ductwork can make all the difference for homes and businesses around Kenosha. Let’s pull back the sheet metal and see what really matters.

Prefab Ductwork: Fast, Cheap, and… Just Okay
Prefab (pre-fabricated) duct sections are mass-produced, designed to fit “most” spaces, and shipped out by the truckload. For some contractors, it’s a fast way to get a job done. But fast and good rarely go hand in hand.
Why does it matter?
- Maximum Efficiency: Tight, well-designed ducts mean your system works smarter, not harder.
- Even Comfort: No more hot and cold spots—just consistent, reliable airflow.
- Quiet Operation: Fewer rattles, whistles, and mystery noises.
- Long-Term Savings: Better fit means fewer repairs, lower bills, and a system that lasts.
The downsides?
- Imperfect Fit: Gaps, awkward joints, and forced connections are common—meaning air leaks and lost efficiency.
- More Seams, More Problems: Every extra joint or connection is a place for air (and your hard-earned dollars) to escape.
- No Room for Personality: Your building is unique—shouldn’t your ductwork be, too?
