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!

Here’s What Others Are Saying About Us

Carlos and Chandler were SUPERB installers! We got a very effective AC and Heating system for far less than I expected. We felt the difference right away as soon as we turned on the air conditioning unit. As important, Mauzy configured the system to optimize efficiency. I highly recommend you get a quote from this company if you’re in need of replacing your old equipment.

Update 2: my trust is restored. Had a little leakage in my box that connects to the fan and Luis went up in the attic and got it all sealed. Luis was very polite, professional, and genuinely happy. His positive attitude was very contagious and made my experience top notch. Also, I am happy to report that Mauzy stood behind their workmanship and covered all repairs under warranty. So so refreshing to have any company stand behind their workmanship. I have been with Mauzy since 2020 and will continue to be their customer. I would recommend Christian, Kylie, or Luis as your tech as well as recommend anyone out there to use Mauzy.Update: My trust is returning to Mauzy. Christian and Kylin came out to repair the repair and get my A/C up and running before the heat returns. Christian and Kyle were very professional, explain everything before proceeding, and let me know that the work would be covered under warrantyI have lost trust in Mauzy, Mauzy doesn’t stand behind their own work and what good is a warranty if you don’t stand behind it (This is a long one so sit tight). Where it all began: March 2020 I purchased a $23K A/C heating system from Mauzy. I was super happy with the install and I still love my system. I faithfully have used Mauzy service for my HVAC system every year since the install. I went with Mauzy bc they claim to stand behind their workmanship for the lifetime of the system (See Mauzy’s Attachment stating it also on their web page). Where the exchange box hooks up to the fan/heater a breach occurred between the box and the fan (service guy found it during my scheduled service in May 2024). It cost me approx $450.00 to have that breach fixed. Not sure why I had to pay if Mauzy offers a lifetime warranty on their workmanship, right? Matt Mauzy, feel free to explain this to me(see Mauzy’s warranty claim attached). I am open minded and perhaps my LA unified school education failed me. I got into it with one of Mauzy’s techs during the 2023 service for an issue with their workmanship. So to keep the peace, I didn’t argue with the charge in May and paid the $450 to have Mauzy repair their workmanship. Sunday 14 July, the repair Mauzy charged me for in May, didn’t hold up. I can’t use my heating or A/C bc it just dumps out in my attic. So Sunday I called the service line and the lady assured me there was no issue and scheduled a service call for the following Monday (15 July) no specified time. So this morning I made sure I was ready by 7am in case a technician showed up early. Around 9:15 I decided to call to see if I could get a better timeline from Mauzy only to find out that I don’t have an appointment yet. Come on Mauzy! why would your service desk make me believe I have an appointment when I don’t? Right? I would not have been so disgruntled if the service desk had told me someone would call me Monday morning to schedule. Matt Mauzy, you need to fix this. The soonest Mauzy can come out to fix their shoddy workmanship is sometime Thursday (maybe). I pray that this weeks heat wave is not too severe (this leads up to a whole other reason I need to get my A/C fixed). I will be thinking of you Matt Mauzy while you sit in your A/C house. Matt, Maybe you could come out from behind your desk and help your service department. I happen to be a tradesman and I have never left a customer in need hanging, especially if it was my fault. Just saying!Alex from Mauzy came out to conduct our annual service for our HVAC system. Good thing bc in of the seams in the unit had a hole and I was heating and cooling my attic. Super glad I have the inspection conducted every year. Alex was able to get the breach fixed and now the universe is rotating in harmony once again. BTW, I have been using Mauzy for the last 5 years (Mauzy also installed my HVAC) and I couldn’t be more satisfied. Mauzy truly does a good job and stands behind their work. Thank you Mauzy!

I am really happy with the customer service at Mauzy. Not only did they get me in promptly to replace my HVAC, they also beat the quotes of the other companies I contacted. Matt, Mario and Kenneth were really great explaining the process and getting the job done. They were respectful of my home and made sure my floors didn’t get dirty and cleaned up all the debris from the install. They made sure the unit was fully functional, testing temperatures and explain how to operate the system. I highly recommend Mauzy.

Kenneth and Mario are brothers! They were very respectful, happy and worked harder than I have ever seen anyone work. I had a pool delivered and on their break they offered to carry it to the backyard for me, and they helped get the last piece of the frame locked in as I was not strong enough to do it. They were so quiet I forgot they were in my attic. They were truly amazing! They cleaned up everything, it was like they were never here. I highly recommend Kenneth and Mario from Mauzy heating air and solar. Great job and thank you!!!

Michael at Mauzy worked very hard for two days to diagnose why our AC isn’t working. He had help from Jared the second day. A couple of burnt parts were replaced but it was determined an electrician was needed before they could complete their job. I did not meet Jared but Michael was professional, diligent, thorough and tidy and a pleasure to work with. I appreciated the detailed report afterwards. I am waiting for an updated invoice that details the discount I am due for signing up for their service plan. An electrician has been out and done his work. I’m waiting to hear about a follow up appointment to finish the AC issue. If I can get back to this review, I will update it when the service is complete. I’m new to Mauzy and so far am impressed.
