Daniel showed us all the photos of the maintenance his done. Explained in details. There was lots of mouse poops on the attic...Daniel offered to spread mousetraps for me. Since he said I'm up here right now. Might as well..He didn't have to do those extras. Had those mousetrap for awhile, very helpful young man, and friendly. Cool Air Solutions thanks for hiring your very best technicians...so far, every tech that you sent to my house are very knowledgeable. Im satisfied. Thank you! .
