Replaced & Up to Code — All in the Same Day
Unexpected water heater failures don’t have to turn into multi-day ordeals. Here’s how our technician diagnosed the problem, replaced the unit, and brought everything up to code before the day was done:
“Dalton was very professional, friendly, and knowledgeable. We had a water heater that wouldn’t light after a windstorm. Dalton came out and tried diligently to get it lit. He diagnosed it as an ignition problem that would be expensive and difficult to repair. He then noticed 3 things with the installation that were not up to code, one of which had potential to be dangerous. Long story short, he was able to replace the water heater and bring it up to code on the same day. He also checked the house‘s second water heater and found additional code violations including no expansion tank. Dalton arranged for an additional tech to come and bring the second unit up to code, also on that same day.
While weren’t expecting to replace a water heater, Dalton made it possible quickly and reasonably priced. Great guy, great work, great company!”
