I can’t say enough good things about Thayer AC. From the first call, they were responsive and professional. They came out quickly, took the time to explain what was going on, and were incredibly honest about what did and didn’t need to be fixed. No pressure — just straightforward, trustworthy service. It’s rare to find that these days. You won’t regret calling them. I am so thankful I did. I honestly feel like I would’ve spent so much more calling anyone else. Highly recommend!!
