A thermostat swap and a new condenser and burner unit: a 2021 Google customer said Tech Unlimited handled both over two calls. That customer wrote that Mike P. replaced the thermostat on one visit and Mark P. replaced the condenser and burner unit on the second. The same 2021 customer called the service prompt on both calls and described both technicians as courteous and friendly. Tech Unlimited holds a 5-star Google rating from a single rating.
Prompt service during the two calls I made. One visit was to replace the thermostat by Mike P. and the second visit was by Mark P. when the condenser and burner unit were replaced. both guys were courteous and friendly. I am very satisfied with Tech Unlimited.
