The Service One tech called Sunday night at 6 pm to inform he had several clients before us since we had no heat.

He arrived at 8:10 to replace batteries on thermostat is why there was no heat.

Thought might be batteries but didn t want to break it so tech showed me how to access them in future.

Great job & attitude & prompt service. Thanks!!!
