Appointment scheduling was extremely quick and the price in the provided estimate was relatively fair, minus the additional items added to the estimate unnecessarily.
My complaint is with recent service itself. (previously I had a much better experience with standard maintenance service)

I didn't feel that the tech seemed all that knowledgeable (didn't seem to understand or believe my explanation of the problem without jiggling all the pipes and conduits running to my equipment downstairs). Two hours after leaving, my AC wasn't working again - which, if his "diagnosis" had been correct, it would still be working ("tripped breaker" when he arrived, but the breaker was still on when it died again - 9 times out of 10, something malfunctions to cause a breaker or disconnect to trip).

The technician spent very little time looking at the unit (maybe 5 minutes), quickly diagnosed it with a commonly diagnosed issue, and then tried to up-sell me annual service against my wishes, along with other items that, as it turns out, are not necessary even if the diagnosis had been correct.

It felt like the guy was sent to just show up and sell me as much as possible, not actually try to resolve my issue. An actual faulty breaker or disconnect is not all that common with a properly functioning unit, as it turns out. I'm lucky to have connections in the industry to educate me when technicians and salespeople might otherwise take advantage.

I realize it's their job to sell services, but I did not feel as if I was provided with any technical assistance that I couldn't have done on my own.
