I called John around 9:30 am and he was at my house by 11. He was very polite and professional. He took pictures of the problem with my AC unit and was able to fix it in a couple of hours. He recommended another part be replaced but put no pressure on me if I wasn't able to afford it at that time. He was able to replace both parts and have my AC up and running like new. I will recommend him to everyone I know.
