Plan the replacement
The installation depends on your home and current equipment.
A compatible tank replacement in the same location may be relatively straightforward. Changing from gas to electric, moving the heater, or installing a tankless system can require additional electrical work, gas piping, venting, drainage, or site preparation.
Your address determines which city or county handles the permit. A county name or mailing city is not enough to assume the authority. We confirm the applicable jurisdiction as part of planning the replacement.
To get started: have your ZIP code, a photo of the current unit, a close photo of its data label, and a wider photo showing the surrounding connections and access.
What we replace
Replace the current heater or compare a different system.
- Tank water heatersLike-for-like gas or electric replacement when the existing location and connections remain suitable.
- Tankless water heatersCompact on-demand equipment that may require a closer review of venting, fuel supply, power, and drainage.
- Heat pump water heatersEfficient electric equipment that needs appropriate room volume, clearances, condensate routing, and electrical service.
- Fuel-type changesGas-to-electric or tank-to-tankless projects can involve more work than a standard replacement and should be reviewed as a complete installation.
Before scheduling
Have these details ready when you contact us.
Your exact location
A city name is a useful start, but the address determines the permit jurisdiction, utility territory, and whether the day’s route reaches the property. Call with the ZIP code to confirm current coverage.
The existing equipment
Identify whether the current heater is a gas tank, electric tank, tankless, or heat pump system. A clear photo of the manufacturer label provides capacity and model information without requiring you to interpret it.
The installation area
A wide photo should show the floor, walls, venting, water lines, shutoffs, drain route, nearby outlet, and access path. The surrounding space often reveals more about the replacement scope than a close photo of the tank alone.
The replacement goal
Tell us whether you want the most direct compatible replacement or want to consider a tankless, electric, or heat pump alternative. A conversion can be reviewed early, before equipment is selected or an appointment is scheduled.
