- It's the first time having issues
- The problem is a minor part (thermostat, heating element, valve)

Frequently Asked Questions
Get answers to common questions about water heater service.
How long does water heater installation take?
Most standard water heater replacements can be completed in 2-4 hours. Tankless installations or conversions from tank to tankless may take 4-8 hours depending on the required modifications to gas lines, venting, or electrical systems.
What size water heater do I need?
For tank water heaters, a household of 1-2 people typically needs 30-40 gallons, 3-4 people need 40-50 gallons, and 5+ people need 50-80 gallons. Tankless units are sized by flow rate (GPM) based on how many fixtures you need to run simultaneously.
How much does water heater replacement cost?
Costs vary based on the type and size of unit. We provide free estimates with upfront pricing so you know exactly what to expect. Financing options are available to help manage the investment.
Should I repair or replace my water heater?
Generally, if your water heater is less than 8 years old and has a minor issue, repair makes sense. If it's over 10 years old, has a major problem like a leaking tank, or you're facing frequent repairs, replacement is usually more cost-effective.
Gas or electric: which water heater is better?
Both have advantages. Gas water heaters heat water faster and cost less to operate but require venting. Electric water heaters are easier to install, safer (no combustion), and work well with solar panels. We'll help you choose based on your home's setup and preferences.
