Thinking of Installing a Boiler in Your San Diego Home?

You might be wondering: do people in San Diego really need boilers? Aren’t those more of a “New England in winter” kind of thing?

You’d be surprised. Boilers are still going strong in plenty of SoCal homes, especially older ones with radiant heating systems. Plus, newer high-efficiency models are gaining popularity for their whisper-quiet operation, low maintenance needs, and cozy, even heat—none of that blowing dust or drying out the air like forced-air systems.

Whether you’re replacing a clunky relic or installing a boiler for the first time, we’ll guide you through every step of the process. Our techs aren’t just plumbers—they’re certified heating specialists who eat, sleep, and breathe hydronic heat.

The Mauzy Boiler Installation Process

We make the switch to reliable, radiant warmth seamless.

1. Consultation and Assessment

First things first—we send out a Mauzy pro to evaluate your home. We’ll ask the right questions: What kind of heat distribution system do you have (or want)? How many zones? What’s your square footage? How’s your insulation?

We also take a look at your current heating setup, gas lines, and electrical. Then we’ll walk you through your options based on your home, lifestyle, and budget. We’re not here to upsell—we’re here to get you a boiler that fits your needs, not some cookie-cutter “standard model.”

2. System Selection

Once we have the lay of the land, we’ll help you choose the right type of boiler: gas, electric, combi, condensing—you name it.

Maybe you want an ultra-efficient condensing boiler with zoned controls to heat your home and your water. Maybe you’re looking for a simple, durable model that gets the job done. We’ll break it all down for you in plain English and make sure you’re comfortable with your choice.

3. Professional Installation

This is where the real magic happens. Our certified installers show up on time, keep things tidy, and work with precision. We’ll remove the old unit (and dispose of it properly), handle any necessary retrofitting, and get your new boiler connected and calibrated perfectly.

Gas lines, water lines, thermostats, venting—every detail is double-checked. We’ll test everything, walk you through how to operate the system, and make sure your home feels like a warm hug again.

Reliable Boiler Repairs When You Need Them Most

No heat? Weird noises? We’ve got your back, fast.

Boilers are tough, but even the best ones can hit a bump in the road—especially if they haven’t had regular maintenance.

Here in San Diego County, we see it all: pilot lights that won’t stay lit, pressure problems, weird gurgling sounds, heat that’s only kind of working, or systems that just give up completely.

The good news? Mauzy’s repair techs are trained to fix all makes and models. We show up with stocked vans, troubleshoot like pros, and aim to get your system back online in one visit.

Common boiler issues we repair:

  • No heat or inconsistent heating
  • Leaking or dripping water
  • Low boiler pressure
  • Banging, clunking, or gurgling noises
  • Thermostat malfunctions
  • Pilot light or ignition issues
  • Radiators not heating evenly

We don’t do “band-aid” fixes, either. Our repairs are built to last, and we’ll always be honest if a replacement is the smarter move.

Annual Boiler Maintenance = Long-Lasting Comfort

Think of it like a spa day for your boiler.

Want to keep your boiler humming along year after year? It’s all about preventative care.

With a Mauzy maintenance plan, we’ll inspect your system annually to make sure everything’s running efficiently and safely. That includes checking for leaks, cleaning heat exchangers, testing safety controls, flushing the system, and adjusting any components that are out of whack.

We’ve seen firsthand how a quick check-up can prevent thousands in future repairs. Plus, regular maintenance keeps your energy bills lower, extends your system’s lifespan, and protects your manufacturer warranty.

The Boiler Advantage: Why Homeowners Still Love Hydronic Heat

We get this one a lot: “Aren’t boilers outdated?”

Not at all! In fact, many homeowners in San Diego are rediscovering the quiet, clean, and even heat that boilers provide.

Here’s why boiler systems still have major staying power:

✅ Silent Operation

No fans. No blowers. No rattling ducts. Just warm, radiant heat rising gently from baseboards, radiators, or in-floor tubing. It’s like heating your home with a cozy whisper.

✅ No Airborne Allergens

Since boilers don’t rely on forced air, they don’t circulate dust, pet dander, or allergens the way traditional HVAC systems do. That’s a huge plus for allergy sufferers and anyone who wants cleaner indoor air.

✅ Zoned Comfort

Boilers can be zoned easily, meaning you control the temperature in each room or level. You’re not wasting energy heating empty spaces, and no more thermostat wars with the family.

✅ Energy Efficiency

Modern condensing boilers offer up to 95% AFUE (Annual Fuel Utilization Efficiency). That means nearly all the fuel you burn goes directly to heating your home—not up the chimney.

✅ Durable and Long-Lasting

With proper care, a high-quality boiler can last 20–30 years. That’s nearly double the lifespan of many forced-air systems!

Does a Boiler Make Sense in San Diego’s Climate?

Absolutely! While we’re not battling snowdrifts in Mission Valley, chilly winter mornings and damp coastal air still call for reliable heat.

In fact, boilers are perfect for San Diego’s milder winters. They provide steady, radiant warmth without overheating your home. Plus, with no ductwork needed, they’re great for older homes or modern builds with radiant floors.

And if you opt for a combi boiler, you can heat your home and your hot water from the same compact, efficient system. That’s a two-for-one deal that saves space and energy.

Signs Your Boiler May Need an Upgrade

Sometimes, it’s just not worth nursing that old unit anymore. Here’s when it might be time to trade in your boiler for a newer, high-efficiency model:

  • Your boiler is over 15–20 years old
  • Repairs are becoming frequent and expensive
  • Heating is inconsistent or takes forever to kick in
  • Your energy bills are creeping higher each season
  • The unit is leaking or making strange noises
  • Parts are getting harder to find

We’ll always explore repair options first, but if replacement is the right call, we’ll walk you through your options honestly and without pressure.

Boiler vs. Water Heater – What’s the Difference?

It’s easy to confuse boilers and water heaters—after all, both involve heating water, right? But these systems actually serve different purposes in your home.

A water heater is designed to heat water strictly for household use—showers, washing dishes, laundry, etc. Traditional models store hot water in a tank, while tankless versions heat it on-demand. On the other hand, a boiler not only heats water but uses that hot water or steam to warm your home through radiators, baseboards, or in-floor systems. Some high-efficiency combi boilers even do both—providing heat and domestic hot water from a single unit.

Still not sure which one you need? Don’t sweat it—our team at Mauzy can help you figure out the best system based on your home’s layout, comfort needs, and energy goals.

Need Water Heater Help Instead? We’ve Got You Covered.

If it turns out you’re just looking to replace or repair your water heater, you’re in the right place for that too. Mauzy proudly offers expert water heater installation and repair services across San Diego County—including both traditional tank-style and high-efficiency tankless systems.

From fixing minor leaks to full system upgrades, our licensed pros are ready to get your hot water flowing fast. Whatever your home needs to stay comfortable, Mauzy’s got the tools, the know-how, and the heart to get it done right. Give us a call or book online today!

Just had Evan G from Mauzy do an evaluation on the plumbing on my home. The evaluation could not have been more complete.
Every bit of the plumbing was checked. Yes everything was good to go but if there was an issue Evan with his knowledge would not have missed a thing. At least 2 hours to go through all the plumbing. I recommend every home owner to get the same service. It will save on the long run and if there are minor issues you will be made aware. Evan G was terrific.

5

Kory was great and very thorough , thank you

Mouzy is hands above any other plumbing/electrical A/C, firm I’ve used in the past, and since I am 80 years old, I’ve used a heck of a lot of them. They are fair, polite, and knowledgeable. I have no idea what More can think of to describe them.
You’ll be happy with them!

Joshua was professional and courteous. His detailed description of filtration systems, along with inspection and recommendations for correction of my failed in line water filter were a sell point for the filter I subsequently purchased from Mauzy plumbing.

I should’ve called Mauzy first! Prior to the call to Mauzy I had 2 companies come out to help me with a plumbing issue I had. Let’s just say it got worse rather than better. Finally, Wilber, an exceptional young man to say the least, came to the rescue! Knowledgeable, efficient, and walked me through every step of the process. Pinpointed the problem and had my plumbing issue resolved. Thank you Mauzy for having exceptional employees that know what they are doing! Will continue my services with Mauzy.

Definitely recommend this company and highly suggest you request Wilber!

5

Mauzy plumbing installed a tankless water heater for me in February and they did a superb job. The technician from Mauzy who installed my tankless water heater was Franky. I recently had a question about my system and Mauzy immediately sent Franky back to my home to evaluate the situation. He did a thorough analysis and determined that everything is good. I’m sure all of the Mauzy technicians are excellent, but if I ever have a complicated plumbing problem in the future, I would specifically ask for Franky; he is extremely knowledgeable and thorough and I can’t recommend him and Mauzy highly enough.

5

Mike Kesner was great! Professional, knew what to do to check the issue and was efficient in its resolution.

5

Excellent both times. Technicians were knowledgeable and polite. Respectfull of my house. Top notch service.

He made sure everything was clean and working perfectly before leaving.

I recently had the pleasure of working with Joe Annello from Mauzy Cooling, Heating, Plumbing, and I cannot say enough about how great the experience was. From start to finish, Joe stood out for his exceptional professionalism and friendly demeanor, making what could have been a stressful situation feel effortless and reassuring. Joe was incredibly thorough in his work, taking the time to carefully assess and diagnose the issue. It was obvious that he takes pride in his work and genuinely cares about providing the best service possible. His attention to detail was truly impressive, and he made sure everything was checked over meticulously before giving his recommendations. What really set Joe apart was his ability to explain everything he found clearly and in a way that was easy to understand. He never rushed through the details or overwhelmed me with technical jargon; instead, he patiently walked me through his findings and the steps needed to resolve the issue. It made me feel confident and informed about the situation, which I really appreciated. Joe’s combination of friendliness, thoroughness, and clear communication truly makes him a standout technician. If you’re looking for someone who is not only skilled but also goes above and beyond to ensure an excellent customer experience, I highly recommend Joe Annello. He represents Mauzy Cooling, Heating, Plumbing in the best possible way and is someone you’d want working on your home!

5

A water heater breaking & unique older home piping/water pressure situation made what should have been a routine water heater replacement a bit more complex, and Ron, Ryan & Kacey were great in helping us get this quoted and serviced in the same day. I appreciate how communicative Ron was and how flexible Ryan was with our crazy schedules!

5

Chris Sotelo, Alejandro, Eddie and Westin were amazing today. They came to install a new A/C Heater unit and did a great work. They were knowledgeable, careful handling the equipment and did everything in a timely way. Thank you to this crew team!
