How to Find the Right Duct Sealing Contractor

Posted: September 2, 2025

Improve Your Comfort, Air Quality & Energy Savings

Did you know that leaky ductwork can waste up to 30% of your home’s heating and cooling energy? That’s money escaping through cracks and gaps in your home, including your HVAC system—while your comfort suffers. Properly sealed ducts not only lower your energy bills but also keep your home healthier and more comfortable. The key is choosing a qualified duct sealing contractor.

Not all contractors are created equal. Some cut corners, while others invest in advanced technology and take the time to do the job right. Here’s what you should look for—and how Wilson Oil and Propane can help.

What to Look for in a Duct Sealing Contractor

• Credentials, Reputation and Warranty: A trustworthy contractor will have proven experience, certifications, and positive customer reviews. Don’t hesitate to ask about warranties—the best companies stand behind their work.
• Advanced Technology: Duct sealing has evolved. Contractors who use innovative methods, like Aeroseal technology, can seal leaks you can’t even see—behind walls, above ceilings, or under insulation. That’s where 90% of leaks often hide.
• Comprehensive Service: A proper duct sealing job should include a full inspection, leak detection, sealing, and insulation of ducts, especially in areas like attics, crawlspaces, and garages.

Why Homeowners Choose Wilson for Duct Sealing

At Wilson Oil & Propane, our certified technicians know all the ins and outs of ductwork. We offer FREE ductwork inspections because comfort problems often start where you can’t see them.

• In newer homes, poor installation is a common culprit.
• In older homes, time takes its toll—causing gaps, leaks, and weakened duct systems.

Either way, the result is the same: reduced air quality, higher bills, and uneven comfort. Our team diagnoses the issue and provides lasting solutions.

The Power of Aeroseal Technology

Wilson Oil and Propane is proud to be an authorized Aeroseal dealer. Aeroseal is widely considered the most effective duct sealing method available today. In fact, the U.S. Department of Energy has ranked it among the top 25 energy-saving technologies introduced since 1977.
