Insulation Gives you





Energy Savings


Energy Stars Heating and Cooling home comfort experts will attach safety on all fronts by performing gas testing, determining what size equipment your home needs, and looking at your home’s current insulation.

Energy Stars Heating & Cooling Co also provides a variety of home comfort services including:

  • Attic Insulation
  • Wall Insulation
  • Crawl Space Encapsulation/Sealing


Other heating and cooling companies miss a critical component when it comes to keeping your house warm in the winter and cool in the summer. Heating and cooling equipment work best when paired with the right insulation and sealing home comfort measures. While there are other insulation companies in our region, they don’t do the job as complete and safe as Energy Stars Heating & Cooling Co, because we take into consideration the appliances, HVAC systems and ventilation as well. As you seal and insulate a house to increase comfort, ventilation becomes a very important consideration, especially when you use gas appliances.


We can help you and offer 100% free consultations, give us a call at 618-577-0200 to schedule.

Energy Stars Heating & Cooling Co Goes Beyond With our:

  • Customized Insulation Packages

  • Full Home Comfort Assessment

  • Complete Safety Testing

The best home insulation companies should be doing these three things to get the best results. We have more details about these three services below.

Home Comfort Assessment

The best home insulation companies should perform a full Home Comfort Assessment to measure and record:

  • Home square footage

  • Window and door sizes

  • Current attic insulation levels

  • Current Ventilation

  • Basement and/or crawl space area

  • Ductwork systems

  • Current heating and cooling systems

  • Check for gas leaks

You will see that our Home Comfort Assessment sets us apart from the competition. We check for every possible place of improvement in, out, and around your home. There are many escape routes for heat in your home, and our job is to find each one.

We take the time to do this, so we can provide a specific customized package for your particular home. Each home is different, so we never take the standard cookie cutter approach to insulation. Our team of BPI certified estimators and home comfort experts assess your home to find the best comfort and energy solutions for your home.

Insulation Packages

Other insulation contractors just show up, add insulation, and call it a day. Energy Stars Heating & Cooling Co packages will give you the exact amount of insulation for all areas of your home including:

Attic Insulation Packages

Crawl Space Encapsulation Packages

Our team insulates and air seals crawl space access, spray foams insulation around rim joist, and insulate crawl space walls.

Safety and Comfort

When you insulate your home with Energy Stars Heating & Cooling Co, you’re not only getting comfort, but you’re also getting peace of mind about what is going on in your home. 

Before we start any project, we perform different safety tests to keep your family safe:

Blower Door Testing

Our home comfort specialists perform this test to help determine how much ventilation your home should have. Ventilation is an important part of home safety because without it, excess moisture can build up in your home. Excess moisture can cause mold in your home which can lead to coughing, runny noses, or more serious issues in people with other health issues.

Combustion Safety Testing

A combustion safety test makes sure all combustion appliances (like your furnace, water heater, and gas stove, or boiler) are working safely and not leaking gas. Our specialized tools detect gases like carbon monoxide in parts per million so we will inform you immediately if there are gas leaks in the home. Carbon monoxide kills over 400 people a year. Since carbon monoxide is colorless, odorless, and tasteless, it can only detected with proper equipment or a carbon monoxide detector. We carry mobile testing equipment so we can find these leaks and keep your family safe.

Why Your Home Needs Insulation:

A High Efficiency Furnace or Air Conditioner Isn’t Always Enough…

You can still lose money with the most efficient furnace or air conditioner on the market, if they are operating in an under insulated home. The right equipment along with the right insulation will make your house feel like your own paradise.

Most homes in the Metro-East area were not built with insulation and if they were it isn't at the proper level. Even newer home building projects regularly do not have enough insulation to cut costs. We see this regular with homes that we go into in this area.

Insulation effectiveness is measured in R-value. The average R-value in homes in this area is R19. Energy Stars Heating & Cooling Co installs insulation to R49 in every project. We do this because R49 is the recommended Energy Star insulation level for our regional climate.

Insulation has many benefits.

With the right insulation levels, you will save money on your energy bills. You won’t have to run your AC or furnace constantly to stay comfortable. This will help keep your energy bill moderate, especially during hot or cold weather extremes.

Another benefit of proper insulation is it will create a sound barrier. With densely packed walls, sound will have a difficult time traveling from the outside. Insulation also controls humidity and can help improve air quality from controlling mold.

If your home has any of these signs, it is time to call Energy Stars Heating & Cooling Co for a Home Insulation Assessment at 618-577-0200.

Different Temperatures in Different Rooms - Your living room may always feel great, but the kitchen feels like an iceberg.

High Energy Bills - If you’re energy bills keep going up, but your usage is about the same.

Cold Walls and Floors - Your walls and floors should feel warm to the touch. If not, heat is escaping.

Drafty Area in the Home - If some parts of your home always have a chill, that means there is less than adequate insulation.

Mice, Bugs, and Other Critters - No one likes to find unwelcomed guests in their home. But having bugs and mice in your home can be a sign there are tiny areas of your home open to the outside. If pests can get it, that means energy is getting out.
