Our company was created from our two founders’ shared vision to combine industry-leading knowledge and expertise, with a passion for service excellence, to operate as THE Water Heater Company.

"Such a good experience from beginning to end! I came back from a trip to find my water heater was leaking all over the place. I was referred to THE Water Heater Company by some friends, whose opinions I hold in high regard, and I was not disappointed. The company gave me straightforward options and said they could respond the next day and would likely be able to replace my water heater that same day. Marc was able to remove my old water heater and replace it with a great brand in the time he said it would take; moving everything up and down 3 flights of stairs and working in a small space. A great experience from start to finish: thorough review of existing equipment and services; thorough explanation of available options and explained better versus worse options; they said what they were going to do and delivered on that. Everything was straightforward and handled efficiently. It was also great to have someone who takes pride and is enthusiastic about the work they do. If every interaction in my day was like this one, I would never have anything to worry about. A big thank you to THE Water Heater Company and to Marc!"

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
