Professional in scheduling and servicing. The technician was very good. I thought the price for the heater service was fair and the work thorough. I joined the monthly club to try it for the next year to make an evaluation of the value. I thought the extra charge to check the humidifiers at $122 each was outlandish and then the extra charge to check the AC system at an additional $99 each for our two systems was excessive. Just give one fair price for a total evaluation, not piecemeal. So, I was disappointed in the pricing model.
