Best Hot Water Circulation in Dallas TX

I had a problem with my water heater and I called this company. They sent someone out who was very prompt, honest and very fair in assessing the problem. However, I ended up having the unit repaired by the person who originally installed the unit. I give this company five stars based upon their willingness to work with me past a slight misunderstanding about the price. (I wasn't told I'd be charged a premium for a weekend call, and I failed to ask how much it would cost.) Even though they didn't end up doing the work, the person they sent was on time, very cordial and patient. I could tell he was a very able employee. I greatly appreciate the way I was treated by those I communicated with. Our compromise, a payment for the service call, was very satisfactory.
