I was without heat for a few weeks waiting for a home warranty company to have someone come out. When they came, they couldn’t help and didn’t do much to attempt to help. I got Derrick’s name and number from another business owner in town, who I use and trust. Derrick came out within a few hours. He informed us that we had the wrong thermostat for pi’s system, but wires it to work until the correct one came in. The new one was delivered this week and he installed it and requires some of it to take advantage of all the the benefits of the system. I highly recommend Innovative and Derrick!
