After calling and calling another HVAC company that would never get back with us, we decided to try Anderson based on their excellent Google reviews. WOW. Kerry was amazing. Very personable and friendly, and very knowledgeable. He knew exactly what to do and took care of the problem. After this very positive experience, we will be using Anderson from here on out! A+++++!

I had a warrantied heat exchanger replaced on my Bryant furnace in December. After the replacement my furnace was making a strange sound. I called and they sent someone out within days to check out what was causing the noise. It was something they had not encountered before. John called and told me they stood behind their work and would figure it out. Over a period of weeks, several techs came out to listen to it with a different perspective, and varied experiences in the field, trying different “fixes”. It took awhile but they narrowed it down to a defective replacement heat exchanger, which they replaced once again. They answered every call promptly and responded immediately. I was not charged any more for all of the time they invested in solving the problem. A special thanks to Ricky, who was here several times, treated me with kindness and respect, and just never gave up! I would highly recommend Anderson HVAC.

I am not a review person but to those of you looking for a great company this is the one. We are dairy farmers who have milk compressor go down and we can’t move our products to different coolers So we need to be up and running in short period of time and this company does it. And a big shout out to Ricky for taking the time and patience to get us up and running last night. With the availability of being able to get parts being terrible you need to think outside the box and he did. You may pay more for their time but this companies employees go above and beyond there job qualifications, they care about their jobs and want the customers to be satisfied in the end. Thanks again to a job well done
