Comment: I appreciated the help and information from Dominique and Bobby. I've never had such an awful time with HVACs, did not know what to do, and they were an enormous help and very professional and cheerful. They can fix it! And they did!
My son, Jon Rini, will call you to clean his system as well.
PS...I did get new filters and put them in. Biggest problem is that I am not tall enough or strong enough to close the attic stairs!
Many thanks!
