Our AC went out on a Thursday right when things began to start heating up in SD. We had guests coming over that weekend and we needed our AC to be working but didn’t know who to call.Luckily, I remember seeing their truck on a the road and gave them a call they were able to get someone out the next day. They were prompt, efficient, honest, and professional.Now our AC works so well we feel like we’re in Alaska! Thank you we’ll be using your company again!

Marty and Dustin from A&B AC & Heating did a superb job of quickly and competently diagnosing our inoperative heater. It was not an easily recognizable problem that required their skillful diagnosis, as well as climbing into our attic multiple times to access the FAU. Marty has provided us service multiple times and we have always been pleased.

Highly recommend!!! My girlfriend, my two dogs and I moved into a new place during the coldest time of the year only to find the heater was broken. I reached out to A & B Air Conditioning & Heating and they couldn't have been more efficient. Extremely helpful, flexible and reliable. I highly recommend them!!!

Unsafe driver with no regard for anyone else on the road. License plate “AC GOD” swerving in and out of traffic, bad impression of the company

10/10 recommend A&B Air Conditioning and Heating! I hired them to replace my air ducts and the price was an incredible value for the quality of work and amazing customer service. Dustin is 100% why I'll come back to A&B for all my HVAC needs - he's professional, highly responsive, and just overall great human. I recently needed to replace a register that a handyman I hired painted over (who does that, by the way?!) and I couldn't get it back on myself and connected to the duct in the attic. I texted Dustin and he sent Fidel (who is also great) over within a day to install the new register at no additional cost. Just really great humans all the way around, thanks A&B!
