Your HVAC Might Be Wasting Air — and You’d Never Know Without a Test.

Most people don’t think about their ductwork. It’s out of sight and (usually) out of mind. But if your ducts have small holes, loose joints, or poor seals, a big chunk of your heated or cooled air may be leaking into places like your attic, basement, or walls — instead of reaching the rooms you live in.

At Novus Mechanical, we offer professional duct leakage testing in Freehold, Marlboro, and Manalapan to help you get real answers. Whether you're noticing uneven temps, rising bills, or are just curious about how your system is performing, we’ll show you exactly what’s going on — and how to fix it.

🛠️ What’s Included in Our Duct Leakage Testing Service:

• ✅ Installation of specialized testing equipment (Duct Blaster or similar)

• ✅ Pressurization of the duct system to detect and measure air leakage

• ✅ Sealing of registers and returns to isolate the ducts during testing

• ✅ Measurement of leakage rates (CFM) and efficiency scoring

• ✅ Clear, written report with problem areas and suggested fixes

• ✅ Time to walk through the results and answer every question

The result? More efficient airflow, better comfort, and peace of mind knowing exactly where your home stands.

😣 Do Any of These Sound Familiar?

We hear things like this all the time from homeowners:

• “Some rooms never feel comfortable — no matter what the thermostat says.”

• “Our AC runs constantly but never seems to cool the house.”

• “I just had a new system installed… and nothing changed.”

• “Nobody ever tested the ductwork before.”

• “Our energy bills are getting higher every season.”

• “The last tech told me it was ‘normal’ — but it doesn’t feel right.”

• “They scheduled me and never showed up.”

That’s why we do things differently. At Novus, we believe in data, not guesses. We test, explain things clearly, and treat your home with care. Nova — our glowing spirit of comfort — reminds us that every family deserves real answers, not just opinions.

🧡 A Marlboro Home That Finally Got Answers

A Marlboro homeowner called us after replacing her HVAC system — twice. The house was still drafty and uneven, especially in the upstairs bedrooms. She was told it was “just the way the house is.” We performed duct leakage testing and found over 30% of her conditioned air was escaping through leaks in the attic ducts. After sealing the system, the home felt balanced for the first time in years. “You’re the first people who actually tested something,” she said. “Now I know it wasn’t in my head.”

❓ Duct Leakage Testing FAQs

Why isn’t my ductwork working right?

Leaks in joints, holes in flexible ducts, or poor sealing at vents are all common — even in newer homes. You’ll never know how much air is escaping until you test.

How do I know if I need repair or full replacement?

We’ll start with testing. If the leakage is moderate, sealing and insulation usually fix it. If the ducts are damaged or poorly designed, we’ll explain your options clearly.

Can I test this myself?

Unfortunately, no. Duct leakage testing requires professional equipment and knowledge to perform and interpret correctly. But we’ll explain everything in plain terms.

How much does duct leakage testing cost?

Testing typically ranges from $300–$800 depending on the home and whether it’s combined with a full home performance audit. We’ll give you an upfront quote — no surprises.

Do you offer emergency service?

Duct testing isn’t usually an emergency, but if your HVAC isn’t working or you’ve had major comfort issues, we’ll do our best to prioritize your visit.

Do you guarantee your work?

Yes. Our testing is backed by certification-grade standards, and if you move forward with repairs, we guarantee the results — and your improved comfort.
