San Diego County Boiler Services

Boiler Repair, Maintenance & Installation for San Diego County Homes & Businesses

Boilers are dependable systems, but when they need attention, you want a plumbing company that knows what it’s doing. Plumbing Plus has served San Diego County continuously since 1984, more than 40 years under one brand, one mission, and, now, one family. Michael and Rachael De Silva have owned the company since 2010. We handle boiler repair, maintenance, and installation for both residential homeowners and commercial and property management clients throughout San Diego County.

Whether your boiler needs an urgent repair or a long-overdue inspection, we’re ready to help. Call us any time at (858) 630-3141  for a free estimate and same-day availability.

Boiler Services We Provide

Our technicians handle the full range of boiler service needs. For repairs, that means diagnosing issues with components like the circulator pump, expansion tank, pressure relief valve, thermostat, and ignition system. For maintenance, we inspect and clean burners, check pressure and temperature gauges, test the pressure relief valve, and flush the system to reduce mineral buildup. When a system has reached the end of its useful life, we handle new boiler installation, including sizing, gas and water line connections, venting, and calibration.

San Diego’s hard water accelerates mineral scaling inside boiler systems. The water supply averages around 16 grains per gallon—well into hard water territory—which means mineral buildup is a real and ongoing concern. If your boiler hasn’t been serviced in a few years, that buildup may already be reducing efficiency and putting stress on components. It’s a practical reason to keep up with maintenance even in a mild climate where boilers don’t run as hard as they do in colder regions.

We offer 24/7 emergency service for urgent failures. All of our technicians are screened, background-checked, and arrive in uniform, trained to respect both your equipment and your property.

Signs Your Boiler Needs Professional Attention

In San Diego County’s mild climate, boilers often sit idle for extended stretches without heavy use. That downtime can cause components like the expansion tank and circulator pump to degrade quietly, without any obvious symptom until something fails. Knowing what to watch for helps you act before a small issue becomes a costly one.

Call us if you notice any of the following:

• No heat or hot water from the system
• Banging, gurgling, or whistling sounds from pipes
• Visible water leaks around the unit or pipe joints
• Rising energy bills without a change in usage
• Pressure gauge readings outside the normal range

If your boiler is 15 or more years old and showing repeated performance problems, replacement may be more practical than continued repair. We’ll assess the system and present both options so you can make the right call for your property.

Boiler FAQs

Do You Service Boilers Throughout San Diego County?

Yes. We serve both residential homeowners and commercial and property management clients throughout San Diego County.

What’s the Difference Between a Boiler & a Water Heater?

A water heater heats water for domestic use: showers, dishwashing, laundry. A boiler heats water and circulates it through radiators, baseboards, or in-floor radiant systems to heat a space. Some combination (combi) boilers handle both functions in a single unit.

What Should I Expect When I Call for Boiler Repair?

We’ll start with a free, written estimate before any work begins. Many standard repairs can be completed in a single visit, though timelines depend on the issue and parts availability. If you’re unsure whether you need repair, maintenance, or replacement, a diagnostic visit gives us the information to lay out your options clearly.

Do You Offer Emergency Boiler Service?

Yes. We provide 24/7 emergency service for urgent boiler failures.
