AEMS Service Company did a great job. They were very responsive and came quickly after we called them. The first time, I used them to service my air conditioning unit. On the most recent visit, the technician came to address a problem with the hot water heater. He was knowledgeable and knew what he was doing. One minor problem I had was that it would have been better if he had informed us how much it would cost. But he did fix the issue so I have no other complaints. I would recommend them and will use them again in the future if I need to.
