Water Heater Repairs

Not every problem needs a new unit. We replace thermostats, elements, gas valves, anode rods, relief valves, and fix leaks at the fittings. If water heater repair makes sense, we fix. If a new unit saves you money, we say so.

  • No-heat or not enough hot water
  • Pilot won't stay lit
  • Rusty water or smell
  • T&P valve discharge
  • Noise from sediment

Tankless vs Traditional

Tankless gives endless hot water and frees up space. Traditional tanks cost less up front and handle most homes fine. We help you choose based on family size, usage, gas line capacity, and budget.

Tankless

  • Endless hot water
  • Space saving
  • Energy efficient
  • Higher upfront cost

Traditional

  • Lower upfront cost
  • Handles most homes
  • Proven reliability
  • Limited hot water

Frequently Asked Questions

How do I know it's time to replace the water heater?
Age over 10 years. Rust at the base. Frequent leaks. Slow recovery. If the tank shell is compromised, replacement is the safe call.
Most standard swaps take about 2 to 4 hours. Tankless or relocation work takes longer.
Yes. We assess gas line capacity, venting, and condensate. We size the unit to match your flow needs.
Major residential brands for gas, electric, and tankless. We match parts availability and warranty support in East Idaho.
If the tank is sound, repair can be smart. If a new unit saves money and stress, we say it. Your call with clear numbers.
