My office wasn't cooling and Had been serviced a few months back by a different AC company. Cool mark came promptly when promised even though it was late. I was told the honest truth about needing replacement, but he was able to "patch" it along. He changed my filter also and made sure to ask me how my unit was cooling later on. Thanks cool mark for a great experience! He's recommended by many and I'm glad to have tried them out. support small business owners.

Mark was very professional when I spoke with him about my A/C blowing hot air and not cooling properly. I made an appointment with him to have my unit checked. He was courteous, prompt, and made sure I understood all that was needed to fix the problem. Once the job was complete my home immediately started cooling and for that I m truly thankful he made it out when he did. This Texas heat is no joke!
