You wouldn’t leave a window wide open in the middle of winter, right? Yet, most homeowners unknowingly let warm or cool air escape through leaky ducts. We often overlook small cracks or leaks in our ductwork, but the truth is, they can cost more than we realize.
According to the U.S. Department of Energy, up to 30% of the air heated or cooled in your home can escape through leaky or poorly insulated ducts. That’s a huge chunk of energy and money literally slipping through the cracks, enough to power a small appliance like a refrigerator for months each year!

Duct sealing isn’t just about lowering your energy bills only, but it’s about ensuring your HVAC system operates efficiently. Instead of constantly adjusting the thermostat or struggling with hot and cold spots, you can rely on trusted professionals to solve the problem for you.

Types of Duct Sealing & Insulation Services
repairHVACnow connects you with trusted technicians delivering expert duct sealing and insulation services to boost your home’s comfort, efficiency, and year-round performance.
Duct Inspection & Leak Detection
Using advanced diagnostic tools such as pressure testing, smoke pencils, and thermal imaging, technicians can detect leaks, cracks, loose connections, and insulation issues, even those hidden behind walls, ceilings, or in attics. This step ensures no energy loss goes unnoticed.
Sealing Leaks & Gaps
Once leaks are identified, technicians seal them using professional-grade materials. While standard duct tape can dry out and fail over time, experts rely on long-lasting solutions like mastic sealant, metal-backed tape, and aerosol-based sealing products. Proper sealing prevents conditioned air from escaping and keeps unwanted dust and pollutants from entering your system.
Insulation Installation or Replacement
If duct insulation is missing, damaged, or outdated, technicians can install new insulation or replace existing materials. Proper insulation helps maintain consistent air temperatures as air travels through the ducts, reducing heat loss in the winter and heat gain in the summer. This not only improves comfort but also helps your HVAC system work more efficiently.
Airflow Optimization
Technicians assess airflow throughout your duct system and make adjustments as needed. This may include balancing airflow between rooms, correcting duct sizing issues, or adjusting dampers. Optimized airflow ensures even temperatures, reduces hot and cold spots, and helps your system deliver air more effectively.
Energy Efficiency Assessment
To wrap things up, technicians evaluate your overall HVAC performance and energy usage. They’ll identify opportunities to improve efficiency, recommend upgrades or repairs.
With repairHVACnow, you get peace of mind knowing your ducts are sealed, insulated, and optimized for comfort.
Key Signs Your Ducts Need Sealing or Insulation
Ignoring duct issues can lead to high energy bills, poor comfort, and unnecessary strain on your HVAC system.
Watch for these warning signs:
- Uneven temperatures in different rooms
- High heating or cooling bills despite regular system use
- Excessive dust buildup around vents
- Weak airflow from vents
- Visible leaks or disconnected duct segments
- Hot or cold spots in your home
Addressing these issues early prevents energy waste and avoids costly HVAC repairs.
Duct Maintenance Tips Before Scheduling Service
Before a professional visit, you can take simple steps to maintain your ducts:
- Check vents and registers for blockages
- Keep duct openings clear of furniture or debris
- Replace air filters regularly to reduce system strain
If issues persist, scheduling a professional duct sealing and insulation service is the best way to restore efficiency and comfort.
Benefits of Professional Duct Sealing & Insulation
A well-sealed and insulated duct system offers:
- Lower Energy Bills & Long-term Savings
Why waste money over air loss. Leaky ducts force your HVAC system to work harder and longer than necessary. Professional duct sealing can reduce heating and cooling costs by 10–30%.For the average household, that can mean hundreds of dollars saved each year, savings that continue season after season. - Improved Comfort:
Leaky or uninsulated ducts are a major cause of uneven temperatures. Some rooms may feel too hot in summer, too cold in winter, or never reach the thermostat setting at all.
Sealing ducts can help evenly distribute heating and cooling throughout your home. Hot and cold spots are reduced or eliminated and rooms farthest from the HVAC unit become more comfortable.
This way you’ll spend less time adjusting the thermostat and more time enjoying consistent comfort. - Better Indoor Air Quality:
Leaky ducts can draw in dust and dirt from attics or crawlspaces, insulation fibers, pollen, mold spores, and allergens. Sealing duct leaks prevents dust, allergens, and pollutants from entering your living spaces, improving indoor air quality for your family, especially important for families with allergies, asthma, or respiratory sensitivities. - Reduced HVAC Strain:
When your ducts are sealed and insulated, your HVAC system doesn’t have to work as hard to maintain comfort, which reduces wear and tear and extends the life of your equipment. - Quieter Operation:
Sealed ducts minimize air leaks that can cause whistling or rattling sounds, ensuring your system runs more quietly. - Environmental Benefits:
Lower energy consumption from efficient ducts reduces your carbon footprint, helping you contribute to a greener planet. - Peace of Mind
Perhaps most importantly, professional duct sealing and insulation give you confidence that your HVAC system is operating the way it should. You need not worry about wasted air or energy, but count on reliable comfort.
Typical Time Required for Duct Sealing & Insulation
Most duct sealing and insulation services are typically completed within 2–4 hours, though the exact time depends on the size, layout, and overall condition of your duct system. Homes with easily accessible ductwork can often be finished more quickly, while larger homes and ducts located in attics, crawlspaces, or behind walls, may require additional time.
If your system has extensive leaks, damaged insulation, or hard-to-reach areas, technicians may need extra time to ensure everything is properly sealed and insulated and only they can give you a correct estimate of time.
Before any work begins, a thorough inspection is performed and accurate time and cost estimates are provided, allowing you to plan with confidence.
