Home Insulation Services You Can Trust!

Comfenergy is Nova's preferred home insulation and air sealing services company. We have helped many homeowners not only reduce their home energy bills but improve the overall comfort of their homes without patented home insulation solutions.  Did you know that most modern homes do not have adequate insulation? Because of this, your home may feel drafty or uncomfortable throughout the year, mostly in the summer and winter, and this can increase your home energy costs. Proper insulation in your home allows your heating or air conditioning systems to work more efficiently which will save you money. 

We offer a wide variety of home insulation products and services, and each one serves its own unique purpose.  Our most popular form of insulation is spray foam.  Spray foam insulation is extremely versatile and can be used almost anywhere in your home.  Spray foam insulation is one of the best ways to lower energy costs, sometimes 30% or more!

Along with spray foam, we use many other different types of insulation as well. Some of our other insulation products include rigid foam, blown-in, cellulose, fiberglass, radiant barrier, and much more.  We understand that insulation is only part of the home energy and comfort equation, so because of this, we can insulate any area of your home.  We insulate spaces such as attics, basements, crawl spaces, walls, floors, garages, and much more.  If your home is uncomfortable or energy bills are too high, contact us today for a FREE home insulation quote!

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation Include:

  • Provides both insulation and air sealing; air sealing is excellent because the foam expands to fill gaps and cracks.
  • High R-value -about R-7 per in. depending on the formulation.
  • Speedy installation. Foaming can be done in a fraction of the time it takes to cut, fit, and seal rigid board insulation.
  • Once cured, spray foam insulation stays in place; it won't shift, settle, or fall out of place.

Links Pond Cir in Gainesville
My gas fireplace becomes very drafty when temperatures drop below freezing. I would like to get an estimate for insulating the fireplace. I recently discovered that my home has a makeup vent installed in the unconditioned attic. I would like to discuss options for extending this vent to the exterior of the home. I am also interested in learning more about my home's use of internal air and if I may have a negative pressure issue. This may involve getting an energy audit service at some future date after some other improvements have been made first.
Tenbrook Drive in Gainesville
We have an addition that was built before we bought the house. The addition was built out of a portion of a garage and is very hard to maintain temperature consistent with the rest of the house. As such we have a feeling as if the attic area over the addition was not properly insulated.

I wanted to find out how much it costs to have our ducts checked for leaks? My main concern is that I have allergies and I find our house to be crazy dusty. I read that this can be caused by having leaks in the ductwork.
