Ac doctors are the best. We had our ac outdoor unit go out over forth of July weekend. They were prompt and punctual and even looked up the manufacture warranty to save us money (previous home owners left nothing). We noticed the ac kept freezing over and we called them again. Turns out there was a leak in our coils (house built in 98 likely no care since) Not only did they replace the coils but also found a leak in the duct system and fixed that as well without being being asked. Customer for life.
