Global Cooling did a good job. I had a problem with my air conditioning unit and they did a great job fixing it for me. The problem I had was that it seemed like he was pushing to sell me a brand new unit for a higher cost, rather than just for the fix. He said he did not want to pressure me, but it felt like he was pushing for me to spend more. This was my first time using Global Cooling and they did do a good job, but I would probably try a different company in the future.
