Real People. Real Stories

"I called around 8:30 am this morning and spoke with Greg and he was able to schedule me for a 2:30 pm appointment on the same day. Molly arrived approximately ten minutes early and rocked it! She was very knowledgeable and friendly and because of her I will be using All Star again no if and or buts!!! Greg came in middle of night when furnace failed. He got it running and showed how to keep it running until new unit was ordered and installed."
