Ronnie came out last week and was so thorough and respectful. He was quick and efficient, making sure to explain everything that he found with our AC unit, replacing what he needed to. It didn't feel like it was running up to par through the rest of the week, so I called back on Monday and Ronnie was back out within the hour. He really took is time and examined everything thoroughly and even replaced our filter and another little part on the AC with no extra charge. We have an older house and an AC that needed maintenance. Ronnie was so great, we don't expect perfection from the AC but he was excellent. 100% would recommend!

This is our fourth system that A1 has installed at different properties for us. Always a fair competitive price, and timely install schedule.

We called A-1 on the day after Christmas and our office was 40 degrees. I was so impressed that Thomas arrived so quickly and worked efficiently. Not to mention how kind and empathetic he was. I will be using A-1 for not only my business needs but my personal needs as well! I will also be recommending you to everyone I know! Thank you again.
