A/C Doctors responded to my request for a quote within ten minutes of sending the request to multiple companies via Yelp. They had the best availability among all the companies that responded. They showed up promptly and were professional in explaining the service check they were going to perform on my heater. After about 20 minutes, the service rep outlined what he fixed and recommended another fix. I refused the second fix and there was no pushy sales mentality to get it completed since he said it was not required for the heater to work properly. I will definitely use A/C Doctors in the future.
