I don't mind paying for a service call but my expectation would be more concrete such as using tools to determine if there is a bad parts or options to replace them if any. I don't want to pay $90 for someone to tell me I need to replace my heater with a new one because it is old. Heater is still working.

That already put us in good stead and so we asked them for a quote for a new heating unit as it had been explained to us that something had split. John was excellent, asked all the same questions that others had, but also went into details more about what they could offer - there
