I got to meet with David from Air & Heat Hospital, and he just laid out all the information for me. There was no type of pressure, even face to face, and we came to an agreement. That was excellent because great customer service is like finding a dinosaur these days! Since I've been doing business with them, they have continued the maintenance for spring and fall, and they are always on it, and always on time. They are all for suggestions to keep the system running in good condition, and their customer service is just great!
