Scott's sent Caden out to look at the system. He determined that my thermostat failed and a simple replacement would probably do the trick. He was right! Taking the time to obtain a second opinion saved me over $12K. Caden was professional and knocked out the replacement in no time. Scott's has a couple of winners working there, probably more.

While out of town the thermostat was set at 69 but was over 100 degrees in the house for multiple days. When we returned we contacted the business and they fixed the thermostat but the Vinyl flooring was damaged.

Promises made over and over again but excuse after excuse. Take your business elsewhere.
