I called the company I have my HVAC contract with and they do not install Attic Fans, which is the job I needed done. I contacted Doug with Infinity Air Solutions, Inc. and they came out and and took care of it. I really liked the job they did and would recommend them to anyone. The fan works great and makes a really big difference in my home. I had never used them before, but I will have to say they made me think about changing to their company for my HVAC maintenance contract. Couldn't be happier with how everything turned out.
