We have used Cool Tech Mechanical a couple times and they were really nice to us every time they came out to do some servicing on our A/C unit. Our neighbors were scheduling routine maintenance with them before the summer for a while a gave them a strong recommendation so we decided to check them out and they are great. Very respectful, courteous, and knowledgeable group of gentlemen working for that company, we have never had a bad experience with them. I have already recommended them to my daughter who has also had a very good experience with them. Thanks
