I had just had my downstairs air conditioner replaced, wrote a great review, and suddenly noticed a thermostat problem with my other unit, totally unrelated to the new installation. I did a panicked call to the company only 10 minutes after the guys left. They has someone back to the house in 10 minutes, resolved to problem (18 year old thermostat with corroded 18 year old battery, my bad). Great friendly and effective service.
