My air conditioner was installed by Choate's Air Conditioning, Heating, & Plumbing a number of years ago, and I still use them to do the routine service work on it. A young man came out just a few days ago to do just that. Their workers are always friendly and polite and on time, and it was the same this time. They do good work, and they also clean up well behind themselves. A bunch of lint fell out of the filter and the young man made sure to get it all picked up off the floor for me. I really appreciated that!
