Critical Fixes for Comfort and Efficiency

Is your home chilly in the winter even though your heating system is working hard? Do you struggle to keep your home cool in the summer without costly air conditioning? Improving the energy efficiency of your home with air sealing and insulation can help! Sealing air leaks and properly insulating go hand-in-hand to make your home more comfortable, but it is crucial that your home is properly air sealed before you add insulation to your home.

Getting an energy audit performed by a BPI certified contractor will show you where insulation and air sealing is needed in your home. Hire a participating Home Performance with ENERGY STAR® contractor to insulate and air seal your home and receive up to $2,500 cash back for making energy efficiency improvements.

Air Sealing and Insulation Go Hand-In-Hand

Air sealing & insulation are the top recommendations by Home Performance with ENERGY STAR contractors in Vermont, and here's why:

Lower heating bills
You can save an average of $375 a year in energy costs

Comfort you can feel
Reducing drafts and heat loss results in warm, even temperatures.

Healthier home

Air Sealing Basics

No matter how much insulation your home has, if there are cracks and gaps, the air you just paid to heat or cool will escape. Stopping air loss by air sealing is one of the least expensive and most cost-effective actions you can take to improve your home's comfort and energy efficiency.

The best way to find where your home is losing the most energy is a by having a professional energy audit. The auditor will find the most important air sealing targets—those spots in your home that are letting the most air in—and can give you the biggest return on your investment.

Remember: Air sealing before insulating will make the insulation much more effective.

Insulation Basics: Why it Matters

Whether you live in an older home or newer construction, chances are you can reduce your energy bills by adding more insulation. No two homes are the same and there are many ways to insulate them. It can often be confusing to determine the right type and amount of insulation for your home.

We recommend hiring a Home Performance with ENERGY STAR contractor that has been trained to identify the insulation needs in your home.
