"When our old AC quit..."

...it was hot outside and inside was worse! We called your company and you installed a new A/C unit and wow, what a difference it made ! Thanks so much for all your help in this air conditioning emergency. We will recommend you to our family and friends."

"I bought a foreclosed home in Marietta, Georgia and I needed to get the AC on quick and it was so hot. I called Billys HVAC and within 2 hours we had cool air. Thank you Billy -- wish you did work in Florida where I live, we could use a good company like yours here locally."
