"I was very impressed with the customer service I received from Appleton Campbell.  The technician that was sent to my house (Michael) arrived on time and spent a lot of time with me going over the various options for my 80 gallon electric water heater replacement.  Michael also took the time to test my well water for me (At no charge) and brought it to my attention that my water was very acidic and that my neutralizer tank was not working properly.  I plan to call Michael back in the next few weeks to have them service my neutralizer tank.
Unfortunately as of April 2015 they are no longer making 80 Gallon water heaters so I was  unable to use this company for the installation.  Michael did provide me with other alternatives to an 80 Gallon tank but the new Hybrid systems are out of my budget and a 50 gallon water heater will not cut it for the size of my house. 
Michael and Appleton Campbell have been added to "My Favorites" on Angie's List and plan on using them in the future for other services/projects.
Make sure to request Michael as your Tech!

"Fine. I had no issues. They got out to the house very quickly, within several hours of request, they were quick with no added charges or time, and the estimates that were requested (replacement of water heater) were explained thoroughly."

"My water heater was leaking, and within a few days of contacting this company a technician inspected the problem, sent me a price quote, scheduled a weekend  installation, and the work was completed promptly, courteously, and for a reasonable price. Excellent customer service all around, and I highly recommend John Dexter."

"My water heater began leaking and so I needed a new one ASAP. I worked with Stelios. He was very responsive via the messaging feature in Angie's List, over email, and on the phone. I found Stelios to be clear in his explanations and forthcoming with my different options, even if they'd put more work on his plate. He worked quickly to find a good water heater and offered to replace it same day. Stelios made sure his work was up to code and made recommendations to improve the installation of the water heater which wouldn't cost any extra. He kept his work area clean and left everything looking good. Our hot water is back and the new water heater is working very well. I am very pleased with Stelios' service and would certainly hire him again."

"The technician arrived promptly at 9 a.m. as scheduled. However, the 50-gallon water heater that I purchased would not fit in the space so the technician had to wait hours for a new one to be brought to my home. He was very courteous and professional. He apologized several times for the delay. A short time after the new water heater arrived, he had everything up and running. This was my first time using Sila, and I would certainly consider contacting the company in the future."
