The bottom blew out of our hot water heater one evening. We called ACE the very next day. They were prompt, polite and answered all our questions. They didn't have the water heater we wanted in stock and it would have taken a few days to get here so we decided on the next size up. It wasn't that much of a price difference and we needed it done. The work was done quickly and properly. We haven't had any problems at all. Would have no issues recommending ACE to others.
