HVAC & Tools Direct is a great resource !

Thanks for the great communication, fast shipping and by the way, I dug for hours online and on the phone before I found HVAC & Tools Direct. They had the parts that nobody else had, and I'll be checking their site regularly from now on. I'd rate them at 10 stars if I could.
