"Hired these guys to replace my original heating and A/C unit. They seem to have done a good job--it works fine. Furnace unit has filter and housing is a little wonky, but it seems to work. They also installed a fancy thermostat which can be read and operated by my phone over the internet. I wasn't too impressed with the thing at first, but I'm away for periods and I've been very pleased with it."

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."
