In today’s energy-conscious world, homeowners are constantly seeking ways to make their homes more efficient and affordable. One of the most effective steps you can take is getting a home energy assessment—a full inspection that uncovers where your home may be leaking energy and costing you money.
But what does an energy assessment cost, and how does Aerosealing ductwork fit into the picture? Let’s break down how these services work together to deliver maximum savings, greater comfort, and cleaner indoor air.
What Is a Home Energy Assessment?
A home energy assessment, also known as a home energy audit, is a detailed analysis of your home’s energy use. Certified professionals inspect everything from insulation and windows to HVAC systems and ductwork. They use tools like infrared cameras, blower doors, and thermal imaging to locate inefficiencies.
What You'll Learn:
- Where heated or cooled air is escaping
- How well your insulation performs
- Whether your ductwork is leaking air
- If your HVAC is working efficiently
- Where your home may be costing you unnecessary energy dollars
What’s the Average Energy Assessment Cost?
The cost of a home energy assessment depends on your location, home size, and depth of the audit. In general:
Service Type
Cost Range
Basic Walkthrough
$0–$100 (may be subsidized by local utilities)
Comprehensive Audit
$200–$600
Advanced Diagnostic Audit (with blower door test, infrared imaging, etc.)
$400–$800+
💡 Pro Tip: Many utility providers and state energy programs offer rebates or free energy assessments under programs like Mass Save (Massachusetts), NYSERDA (New York), and others. Always check for local incentives!
Why It’s Worth Paying for a Full Energy Audit
While free or low-cost audits provide a good starting point, investing in a full energy assessment gives you actionable insights and a detailed report outlining:
- Where your home is losing energy
- Projected savings from upgrades
- Recommended improvements (like Aerosealing ductwork or insulation upgrades)
- Rebates and financing options
Think of it as a blueprint for savings—you'll know exactly where to invest your dollars for maximum impact.
One of the Biggest Culprits: Leaky Ductwork
Even if your furnace or AC is running perfectly, up to 30% of the heated or cooled air can be lost before it even reaches your living spaces—thanks to leaky ductwork.
Duct leaks typically occur in:
- Attics
- Basements
- Crawl spaces
- Inside walls
These leaks not only waste energy but also:
- Reduce indoor comfort
- Let in allergens, dust, and pollutants
- Force your HVAC system to work harder
This is where Aerosealing ductwork becomes a game-changer.
What Is Aerosealing Ductwork?
Aeroseal is an innovative, award-winning technology that seals duct leaks from the inside, using a computer-controlled process. Unlike traditional duct sealing (which uses tape or mastic on the outside), Aeroseal injects a fog of microscopic sealant particles into the ducts while the system is pressurized.
The particles stick to the edges of leaks, building up layer by layer until the leak is sealed—without disrupting your walls, ceilings, or ductwork.
Benefits of Aerosealing Ductwork
✅ Immediate Energy Savings
Most homeowners see 20%–40% reduction in HVAC energy use after sealing leaks with Aeroseal.
✅ Enhanced Comfort
Enjoy even heating and cooling throughout your home—no more hot or cold rooms.
✅ Improved Indoor Air Quality
Sealing leaks keeps dust, mold spores, and allergens out of your air supply.
✅ Extended HVAC Lifespan
Less strain on your system means fewer breakdowns and longer equipment life.
✅ Fast ROI
The average Aeroseal job pays for itself in 2–4 years through energy savings alone.
When Should You Consider Aerosealing?
If your energy audit reveals duct leakage—or if you're experiencing any of the following—it may be time to seal your ducts:
- Uneven room temperatures
- High energy bills
- HVAC system runs constantly
- Poor airflow from vents
- Musty or dusty smells
- Noisy ductwork
We typically recommend Aerosealing ductwork after a home energy assessment, when we’ve confirmed the extent of leakage and calculated your potential savings.
How Much Does Aerosealing Ductwork Cost?
The cost of Aerosealing ductwork varies based on:
- Size of your home
- Length and layout of ductwork
- Type of HVAC system
- Accessibility of the ducts
Most residential projects range between $1,800 to $3,000. However, this investment can lead to thousands in long-term energy savings.
🏡 Real-World Example: A Cape Cod homeowner who spent $2,400 on Aerosealing reported a 35% drop in heating costs and quieter, more consistent airflow across all rooms.
Combine an Energy Audit + Aerosealing for Maximum Savings
The best approach to whole-home efficiency is starting with a comprehensive energy assessment. This helps identify if Aerosealing is needed—and what other improvements can compound your energy savings (like insulation upgrades or smart thermostats).

Frequently Asked Questions
❓ How long does Aerosealing take?
Most jobs are completed in 4–8 hours, depending on the size and layout of your ductwork.
❓ Does it make a mess?
No! The sealant is non-toxic, odorless, and doesn’t coat the inside of your ducts—only the leaks.
❓ How long does Aeroseal last?
Aeroseal comes with a 10-year warranty, but tests show it lasts well over 20 years under normal conditions.
❓ Will it reduce noise?
Yes—leaky ducts often cause whistling, banging, or rattling. Aerosealing can eliminate these sounds by stabilizing pressure and sealing vibration points.
❓ Can I get rebates for Aerosealing?
Yes! Many states and utility companies offer energy rebates or tax credits for duct sealing, especially when paired with a certified home energy audit.
