I submitted an online estimate request for a new AC unit yesterday. Comfort Master followed up with me the very next morning. Bob was very pleasant to deal with. He arrived earlier than the scheduled time which worked out great. He took time to understand the needs and usage of our household. After inspecting our current AC unit, he outlined 3 detailed options for us to choose from. At the time of writing this review, we have not made a final decision yet. But, Bob has certainly made a great impression. The estimate was at the right price point.
