A water heater that’s underperforming affects more of your daily routine than you might expect. Cold showers are the obvious symptom, but inconsistent temperatures, strange noises, and water that takes too long to heat all point to a system that needs attention. Water heater repair in San Diego, CA, from Bob Jenson Air Conditioning, Heating & Plumbing gets your system back to reliable operation without unnecessary delays or guesswork.

We work on all major water heater types and serve homeowners throughout San Diego County.

Water Heater Repair Services We Provide

Bob Jenson Air Conditioning, Heating & Plumbing repairs all major water heater types for San Diego homeowners. Whether your system runs on gas, electric, or is a tankless unit, our technicians can diagnose the issue accurately and explain your options clearly.

Tank Water Heater Repair

Traditional tank water heaters are the most common system found in San Diego homes. We repair a wide range of tank unit issues, including failing heating elements, faulty thermostats, sediment buildup, anode rod deterioration, and pressure relief valve problems.

Tankless Water Heater Repair

Tankless systems are efficient and long-lasting, but they’re not immune to problems. Flow sensor failures, ignition issues, and mineral scaling from San Diego’s hard water are among the more common issues we see with tankless units. Our technicians are experienced with tankless repair and understand the specific demands these systems place on components over time.

Gas & Electric Water Heater Repair

Whether your unit runs on gas or electricity, our team has the experience to diagnose and repair it correctly. Gas water heater issues often involve the pilot light, gas valve, or thermocouple. Electric units more commonly develop problems with heating elements or thermostats. We work on both.

When to Call for Water Heater Repair

Some water heater problems are easy to spot. Others develop gradually and get written off as quirks until they become something harder to ignore. Here are some of the more common signs it’s time to call:

  • No hot water or hot water that runs out much faster than it used to
  • Water temperature that fluctuates without explanation
  • Rumbling, popping, or banging sounds coming from the unit
  • Visible rust or corrosion on the tank or connections
  • Water pooling around the base of the unit
  • Discolored or metallic-smelling hot water

Any of these can point to a range of issues, from sediment buildup and failing heating elements to pressure problems and corroded components. Getting a diagnosis early usually means a simpler repair.

What to Expect When You Call Bob Jenson

Our technicians arrive prepared, assess your system thoroughly, and tell you what they find before recommending anything. If a repair is the right call, we’ll explain what’s involved and what it’ll cost. If the system is at a point where repair no longer makes sense, we’ll tell you that, too, and walk you through your replacement options without pressure.

San Diego’s water quality and climate both affect how water heaters perform over time. Hard water accelerates sediment buildup in tank units and scaling in tankless systems. Our team factors in those local conditions when assessing your system and recommending a course of action.

Frequently Asked Questions


How much does water heater repair cost in San Diego?

Repair costs vary depending on the type of system, the nature of the problem, and the parts involved. A minor fix like a thermostat replacement is typically far less involved than repairing a heat exchanger on a tankless unit. The most accurate way to get a number is to have one of our technicians assess the system in person.

Should I repair or replace my water heater?

It depends on the age of the unit, the severity of the problem, and how often it’s needed attention. A system that’s less than eight to ten years old with an isolated issue is usually worth repairing. If it’s older, has needed repeated service, or the repair cost approaches a significant portion of replacement cost, a new unit often makes more sense financially and practically over time. We’ll give you an honest assessment either way.

Can you repair both traditional and tankless water heaters?

Yes. Bob Jenson Air Conditioning, Heating & Plumbing repairs tank and tankless water heaters, including gas and electric units. Our technicians are experienced with all major system types and can diagnose and repair most issues in a single visit.
