"My furnace was giving me a fit, would light but no heat, I'm assuming something like a gas valve or something, the gentleman I talked to said it's a spider web and he would be out to take a look at it and clean it out. He showed up, cleaned out the spider web and I have heat. Now let's talk about honesty, he could have came out and said I needed new parts and racked up a bill, nope not this place. You don't get service like this very often. I'm a customer for life now."

"This company is great. We had a complete system installed. The installation team were very informative and respectful. When they left it looked like no one had been here, it was clean. The sales person Eric was great he really helped us understand every thing about the system. He also was instrumental in helping to fine tune our system. I have never been involved with a company that really cared about customer service as AS Contrera does."
