      Using a whole house fan to cool your home reduces the amount of time your A/C is in operation during the year, prolonging it’s lifespan and the cost to repair or replace your A/C system.

      HOW QUIETCOOL WORKS

      Open a few windows any time it’s cooler outside than inside, typically in the morning and evening

      Turn your QuietCool fan on by setting the speed and timer.

      QuietCool pulls in cool, fresh air from outside and expels hot, stale air out attic vents.

      Your home has now been made cooler, healthier, and more comfortable.

      JOIN THE QUIETCOOL REVOLUTION!

      The difference in our house is amazing. There used to be an odor we couldn't figure out. Our house had an at least 8-degree difference between the first and second-floor temperature. They are now equal in temperature. The furnace and air conditioner have been working less. The new whole house attic fan is a wonderful addition, as it is very quiet and strong. We've used it a lot. All of our bathroom exhaust fans and the whole house fan is hooked up properly. Everyone that came to our house was very nice and did an awesome job. We are very happy with a good job done. Thank you.

      - Sarah H. St. Louis Customer

      We were unaware of what was involved in an energy audit, and your auditor took the time to explain everything. We were impressed with the report, which told us the areas in which we need to take action. He never pressured us to use any particular contractors, he just suggested that we go to the Home Energy Team website to select contractors of our own choice. He did an excellent job, and we HIGHLY recommend the Home Energy Team Affiliates. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB! Cynthia Simpson

      - Cynthia Simpson, Saint Louis, MO 63122 Customer

      We had the representative come out for an Energy Assessment. We found that he was very informative, professional, and not high-pressure. He explained in great detail about the program and helped us with any questions or concerns that we may have had. His experience and understanding made us feel comfortable with the program and the company. He made it very personable with us and helped us a great deal. We are very happy with the final results and when we are looking to do some other types of work, Greenmark Home Performance will be first on the list. Cynthia Simpson
