    “It's nice to have a go-to guy when the unit goes down. ”
    “These guys get you going and fast !!! Thanks, guys.”
    - Mark T.
    “I knew immediately by their professional design of their website that they could be trusted.”
    Our air conditioner's fan motor went out at the very beginning of summer and being a young family on a small income, I was immediately stressed. I went on the Internet and found Annison-Bitter. I knew immediately by their professional design of their website that they could be trusted. To my relief, they also offered finacing which was such a blessing. I called the next morning, and I kid you not - within 2 hours, Tim had made it to my house and changed out the part and everything was running smoothly. I will always recommend Annison-Bitter to all of my friends!!!
