Professional Duct Sealing Services in Amherst, NH

When your home’s air ducts develop leaks, gaps, or disconnections, you’re essentially throwing money out the window every time your heating or cooling system runs. At Paul the Plumber, we specialize in comprehensive duct sealing solutions that restore your HVAC system’s efficiency and dramatically improve your indoor comfort. Our family-owned and operated business has been serving Amherst and surrounding communities for 22 years, bringing expert knowledge and proven techniques to every duct sealing project we undertake.

The average home loses 20 to 30 percent of conditioned air through duct leaks, according to Energy Star estimates. This means nearly a third of the air your HVAC system produces never reaches its intended destination, forcing your equipment to work harder and run longer cycles to maintain comfortable temperatures. Our licensed technicians use advanced diagnostic equipment to identify problem areas throughout your ductwork system, ensuring we address every leak point that’s compromising your home’s efficiency.

Understanding the Duct Sealing Process

Our comprehensive duct sealing service begins with a thorough inspection using specialized cameras and pressure testing equipment. We examine every accessible section of your ductwork, looking for visible gaps, disconnected segments, and areas where the original seal has deteriorated over time. This diagnostic phase allows us to create a complete picture of your system’s current condition and develop a targeted sealing strategy that addresses all problem areas efficiently.

Once we’ve identified all leak points, we employ professional-grade sealing materials specifically designed for HVAC applications. Unlike standard tape or caulk that homeowners might attempt to use, we utilize mastic sealant and specialized metal-backed tape that creates permanent, flexible seals capable of withstanding the constant pressure changes and temperature fluctuations your duct system experiences. Our BBB accredited team with an A+ rating ensures every seal meets industry standards for durability and performance, backing all our work with a comprehensive 2-year parts and labor warranty that extends to 3 years when you join our club membership program.

Signs Your Ducts Need Professional Sealing

Recognizing when your ductwork requires professional attention can save you significant money on energy bills while preventing more serious HVAC problems from developing. Common indicators include rooms that never seem to reach comfortable temperatures regardless of thermostat settings, excessive dust accumulation despite regular cleaning, and unusually high energy bills that can’t be explained by seasonal changes or rate increases. You might also notice whistling sounds coming from vents or feel drafts near duct connections in accessible areas like basements or attics.

Indoor air quality issues often stem from leaky ductwork as well. When ducts develop negative pressure due to leaks, they can pull in contaminated air from unconditioned spaces like crawlspaces, attics, or wall cavities. This introduces dust, insulation particles, pest droppings, and other pollutants directly into your living spaces. Our technicians, all licensed and background checked professionals, understand these health implications and take special care to seal your system properly, preventing contamination while improving overall air circulation throughout your home.

Energy Savings and Return on Investment

Professional duct sealing typically reduces heating and cooling costs by 15 to 25 percent, with some homes experiencing even greater savings depending on the severity of existing leaks. In New Hampshire’s climate, where we experience both harsh winters and humid summers, these savings accumulate quickly. Most homeowners recover their duct sealing investment within two to three years through reduced energy bills alone, not accounting for the extended HVAC equipment life and improved comfort that proper sealing provides.

Beyond direct energy savings, sealed ductwork reduces strain on your heating and cooling equipment. When your system doesn’t have to compensate for lost air, it cycles less frequently and operates at optimal efficiency levels. This translates to fewer repair calls, extended equipment lifespan, and delayed replacement costs. With thousands of verified 5-star reviews across multiple platforms, our customers consistently report noticeable improvements in both comfort and operating costs following our duct sealing service.

Advanced Sealing Technologies and Methods

We employ several cutting-edge techniques to ensure comprehensive duct sealing results. Aerosol-based sealing technology allows us to reach and seal leaks in inaccessible areas without invasive demolition. This computer-controlled process releases polymer particles that accumulate specifically at leak points, building up until the gap is completely sealed. For larger gaps and disconnections, we perform manual repairs using sheet metal patches, high-quality sealants, and reinforced connections that restore structural integrity while eliminating air loss.

• Pressure testing before and after sealing to quantify improvement and verify results
• Thermal imaging cameras to identify temperature variations indicating hidden leaks
• Smoke pencil testing for pinpointing smaller leaks in accessible areas
• Blower door testing to evaluate overall home envelope performance
• Zoning system evaluation to ensure proper damper operation and seal integrity
