I have been happy with past service over several years to the point where i asked them to take care of my mom's ac and heat as well. I also bought a new heat pump and condensor from them and had them install it. They also did 2 repairs on the new heat pump since the install. However, lately the guy they had been sending for the annual maintenance checks started acting like i killed his best feiend for some reason. Apparently i offended him but i have idea what i might have done to get that reaction from him. Makes me wonder if i need to find another maintenance firm.
