    “Excellent Service”
    Anniston and Bitters installed my HVAC during the construction of my townhome community. The unit installed was the proper size for my home. Today was my semi annual cleaning and maintenance check. A very skilled and personable maintenance technician named Trey completed the work. Trey was very mindful of my dogs and cleaned up after himself. He explained everything he was going to do and recommended the new 6-month filter. He commented that he utilize the filter in his home so I signed up for Anniston Bitters semi annual maintenance program, and they change the filter out at the same time. So to sum it all up, great service excellent maintenance by Trey ,semi annual maintenance service and you never have to touch your air conditioner filter again! Thank you Anniston Bitters and Trey for giving me one less thing to think about.

    “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!!!
