Water Heater Installation & Repair

Your water heater works harder than almost any other appliance in your home. When it starts to fail, it rarely gives much warning — and it never picks a convenient time. Copper Hound provides same-day water heater repair and replacement with upfront pricing and a 1-year warranty on all work.

  • High-efficiency models that reduce energy costs
  • Same-day installation available in most cases

Frequently Asked Questions
Tank water heaters typically last 8–12 years with proper maintenance. Tankless models can last 20 years or more. If your tank is approaching 10 years and showing any symptoms, replacement is often more cost-effective than repeated repairs.
If your unit is under 7 years old and the repair cost is under 50% of a new unit, repair usually makes sense. If it's older or the repair is major, replacement is often the smarter investment — and you'll benefit from improved efficiency immediately.
A standard tank replacement takes 2–4 hours. Tankless installation may take 4–8 hours depending on venting requirements. We'll give you a precise time estimate before we begin.
A family of 1–2 typically needs 30–40 gallons; 3–4 people need 50 gallons; larger households may need 75+ gallons or a tankless system. We'll assess your household's demand and recommend the right size.
