Boiler Repair and Installation in Los Gatos, CA
We are your local Los Gatos Plumbing and Air Pros, and boilers are some of our favorite systems to work on. They are not the most common form of heat in this part of the South Bay, but the homes that have them tend to be carefully built, carefully loved, and tied to the kind of gentle, even warmth that forced air systems cannot quite match. Whether you are running cast iron radiators, baseboards, or a radiant floor, a healthy boiler is the quiet engine that makes your home feel right on a cold morning.
We are the trusted local boiler repair and installation experts in Los Gatos, and we have spent years servicing hydronic systems across this town. From long held homes near downtown and Almond Grove to hillside builds tucked above Kennedy Road, from older properties along University Avenue to newer custom homes with modern radiant floors, we know how boilers are typically installed here and how each style of system is supposed to behave.
Whether your boiler is short cycling, dropping pressure, leaking, or simply nearing the end of its useful life, we are your local HVAC pros you can count on. We bring careful diagnostics, fully stocked trucks, and the kind of straight talk that helps Los Gatos homeowners make smart decisions about systems that often serve a home for decades.
Our Boiler Repair and Installation in Los Gatos, CA
Boiler work breaks down into two related but distinct categories for most Los Gatos homeowners: focused repair work on a system that has served the home for years and clean installation of a new boiler when an older unit has finally reached the end of its life. Here is a closer look at how we handle each one.
Boiler Repair
Most boiler problems do not start with a complete failure. They start with smaller signs: pressure that creeps higher than it used to, a radiator that never quite warms up, a faint knocking in the pipes, or an aging circulator that has started to hum louder than usual. Catching these issues early is the heart of good boiler repair, and it is the work we do across Los Gatos every heating season. Hydronic systems are unforgiving of poor work, but they reward careful attention with the kind of steady, quiet performance that keeps homeowners attached to them for decades.
Los Gatos winters are mild compared with many parts of the country, but the damp cold mornings between late fall and early spring still pull real work from a hydronic system, especially in homes that rely on radiant floors or cast iron radiators to hold a steady temperature through the night.
Common Problems We Fix
- Boilers that fire briefly then shut off
- Cold radiators or baseboards even when the system is running
- Pressure gauges reading too high or too low
- Leaks from valves, fittings, or the boiler itself
- Knocking or banging in the pipes during operation
- Pilot lights and igniters that fail repeatedly
- Radiant floor zones that no longer heat evenly
- Expansion tanks and circulators reaching the end of their life
- Higher gas bills tied to a less efficient unit
Our boiler repair process starts with real diagnostics. We test the system under live operating conditions, check every safety control, measure combustion, and verify pressures, expansion, and circulation across each zone. That sequence finds the actual fault quickly rather than guessing at parts. Repairs are made with quality components and careful technique, since hydronic systems are sensitive to small details that bigger pieces of equipment can hide. When a repair is the right call, we make it. When the unit has reached the end of its useful life, we walk you through clean replacement options that fit the home’s existing piping, zones, and layout.
Boiler Installation
When a boiler has reached the end of its useful life, the right replacement makes a noticeable difference in daily comfort, operating costs, and reliability for the next fifteen to twenty years or more. Boiler installation is a careful project, with more moving pieces than a typical forced air swap, and it is the kind of work where local experience and attention to detail show up across every cold morning that follows.
Older Los Gatos homes with hydronic heat often have decades of plumbing history connected to the boiler, including original piping, valves, and zones that may need to be addressed during the install. Modern high efficiency boilers also bring new requirements around venting, condensate handling, and pressure controls that older units never had to manage.
Common Problems We Fix
- Boilers fifteen to twenty years or older that are failing more often
- Repair calls that have stacked up beyond what makes sense
- Visible rust, scale, or leaks on an aging unit
- Pressure issues that no longer respond to repairs
- Energy bills climbing winter after winter
- A recent home purchase with an aging boiler the previous owner never replaced
- Plans to add radiant floor zones or expand the system
- Old atmospheric units the homeowner wants to upgrade for efficiency
- Concerns about safety on an aging boiler reaching the end of its useful life
Our boiler installation process starts with a real assessment of the existing system, the heat load of the home, and how the zones, circulators, and piping are laid out. From there we size the new unit correctly, plan the gas, electrical, venting, condensate, and water connections, and remove the old boiler cleanly. The new system is set in place, connected to the existing piping with the right transitions, and commissioned with a full startup procedure. We test combustion, check pressures, balance the zones, and confirm even heat delivery across every radiator, baseboard, or radiant area before we walk away. Done right, a new boiler should quietly serve your Los Gatos home for many years to come.

Why Los Gatos Homeowners Choose Los Gatos Plumbing and Air Pros
There are plenty of companies that will look at a boiler. Far fewer treat the work with the level of care these systems deserve. Here is what our Los Gatos clients tell us makes the difference.
Real Hydronic Expertise
Hydronic systems are not a side specialty for us. We work on boilers, radiant floors, baseboard heat, and cast iron radiators regularly, which means we walk into your home with real depth in how these systems behave. Pressure, expansion, circulation, and combustion are tightly connected in hydronic work, and small details matter. We bring that attention to every boiler call we run across Los Gatos.
Careful Diagnostic Approach
A homeowner near Blossom Hill Road called us last winter after a previous company had been chasing a pressure issue on their boiler by replacing parts over several visits without solving the underlying problem. A careful diagnostic showed a tired expansion tank and a stuck pressure relief valve, both replaced in a single afternoon with the boiler running clean again before dinner. That kind of root cause work is the standard for every boiler call we take.
Deep Local Knowledge of Los Gatos Homes
We have worked on hydronic systems in homes across downtown, Almond Grove, Belgatos, Vasona, and the hillside neighborhoods along Shannon Road. We know how boilers are typically installed in this town, where the original piping tends to run, and which configurations are common in older builds. That familiarity speeds up every visit and helps us avoid surprises later.
Clean Workmanship That Lasts
Boiler work is detail work, and a clean install or repair pays back across every season that follows. We use quality components, properly support piping, set boilers level and square, route venting and condensate carefully, and finish the area so the mechanical space still looks neat years later. The result should be the kind of work that holds up across the long life of a hydronic system.
Honest Repair vs Replace Guidance
Boilers can be expensive to replace, so the repair versus replace conversation matters more than it does with many other systems. We tell you straight which path makes sense based on age, condition, and how the home is being used. A well maintained boiler is often worth saving. One that has reached the end of its useful life is better replaced before a midwinter failure forces the decision.
Long Term Local Support
When we install or service your boiler, you have a real local number for the next time anything related to heat comes up. Whether that is an annual checkup, a small follow up question, or a future zone expansion years down the road, you are not starting over with strangers.
Our Service Process
A good boiler service or install follows a clear process from start to finish. Here is what working with us actually looks like.
Step 1: Clear Phone Intake
When you call, we listen. We ask about the system, its age, the symptoms you are seeing, and any history of past repairs. If the situation is urgent, like a complete loss of heat in cold weather, we treat it that way. If it can be scheduled, we lock in a window that fits your day.
Step 2: Thorough On Site Diagnosis
When we arrive at your Los Gatos home, the first job is to understand the system, not to start replacing parts. We test the boiler under live operating conditions, measure pressures, check combustion, verify safety controls, and walk every zone. That sequence finds the actual issue rather than masking it.
Step 3: Plain Language Options
Before we touch anything beyond diagnostics, we explain what we found and walk you through the options. Repair, replacement, or sometimes a smart hybrid path that addresses the immediate issue while planning for an upcoming upgrade. No pressure, just clear information.
Step 4: Clean Repair or Install, Testing, and Walk Through
We complete the work to a standard we are proud of, commission the system properly, and verify every zone is heating the way it should. Before we leave, we walk you through what we did, show you how the system is operating, and answer every question you have.
Service Area in and Around Los Gatos, CA
Los Gatos is our home base, and we know its neighborhoods well, from the streets around Los Gatos High to the hillside roads above Kennedy Road. We also serve the surrounding communities that share so much of the same housing stock and the same Bay Area winter conditions. Our regular boiler service area includes Los Gatos, Monte Sereno, Saratoga, Campbell, San Jose, Cupertino, and the nearby West Valley areas.
Whether you are in a long held mid-century home with original cast iron radiators, a hillside property with a modern radiant floor system, a townhome along Los Gatos Boulevard, or a custom build near the Monte Sereno border, we bring the same level of care and the same depth of hydronic experience to every boiler call. If you are not sure whether your address falls inside our service area, give us a call and we will let you know right away.
Professional Boiler Repair and Installation vs DIY Attempts
Los Gatos is full of capable, hands on homeowners, and we respect that. There are a few boiler related tasks that make sense for a homeowner to handle: checking the pressure gauge against the recommended range, bleeding air from radiators that have started to feel cold at the top, listening for unusual sounds during a heating cycle, and keeping the area around the boiler clear of clutter. Those small checks catch real problems early.
The work below that surface is a different story. Boilers combine gas or electrical service, pressurized water, combustion air, venting, and a network of safety controls into a single tightly coordinated system. A pressure relief valve replaced without understanding the root cause can mask a serious issue. An expansion tank charged to the wrong pressure leads to the same problem returning within weeks. Combustion adjustments made without proper analysis can damage the heat exchanger and create real safety risks. Modern high efficiency boilers add condensate handling, modulation, and tighter control schemes that require real training to set up correctly.
If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.
Beyond safety, there is the long term cost question. A well diagnosed repair is almost always less expensive over the life of a boiler than a series of guesses, because each unnecessary part replacement adds up while the actual issue keeps damaging the system in the background. A new boiler is also a meaningful investment in your home, and the equipment performs best when it is sized and installed by hands that work on these systems every week. For the steady, gentle heat that hydronic systems are known for, calling your local Los Gatos HVAC pros is almost always the smarter play.

Frequently Asked Questions
How quickly can you respond to a boiler problem?
For most boiler calls in Los Gatos, we can be on site the same day, especially during the heart of the heating season. For true emergencies like a total loss of heat during cold weather, we move as fast as we safely can. When you call, we give you a clear arrival window.
How long should a boiler last?
A well installed and maintained boiler often serves a Los Gatos home for fifteen to twenty years or more. Cast iron units in older homes sometimes last even longer with steady care. Modern high efficiency boilers usually run fifteen to twenty years when they are serviced consistently.
How do I know if my boiler needs repair or replacement?
Age, condition, and repair history all factor in. A unit under about ten years old with a single failed component is usually a strong repair candidate. A fifteen year old boiler with recurring problems, leaks, or efficiency issues is often a better replacement. We walk through both options honestly so you can decide what fits your home.
What are the signs my boiler is failing?
Common signs include boilers that fire briefly then shut off, cold radiators while the system is running, pressure gauges reading off, leaks from the unit or valves, knocking sounds in the pipes, and aging units that have lost efficiency. Catching these signs early often means a repair rather than a replacement.
How often should my boiler be serviced?
Once a year is a good baseline for most Los Gatos homes, ideally before the heating season starts in earnest. Regular service catches small issues early, keeps combustion clean, and extends the useful life of the unit. We help our boiler clients set up a simple yearly rhythm.
Are high efficiency boilers worth the upgrade?
For homeowners staying in the home long term, often yes. Modern condensing boilers run quieter, modulate to match the actual heat demand, and use less gas to do their job. Over the life of the unit, those differences add up in both comfort and operating costs.
Can you work on radiant floor systems?
Yes. We service and install boilers tied to radiant floor zones, including troubleshooting individual zones that have fallen out of balance and adding new zones during remodels. Radiant work rewards careful planning, and we bring that approach to every project.
Why is the pressure on my boiler dropping?
Dropping pressure is usually a sign of a small leak somewhere in the system, a tired expansion tank, or a pressure relief valve that has started to weep. We diagnose carefully to find the actual source rather than just topping up the system, since adding fresh water repeatedly introduces oxygen that can shorten the life of the boiler.
How do I find a reliable boiler company near me?
Look for a real local team with strong reviews, careful diagnostics, and real hydronic experience. Boilers are not as common as forced air systems in this area, so depth of experience matters more than it does with everyday HVAC work. We have spent years building that reputation across Los Gatos.
What is the difference between a boiler and a furnace?
A furnace heats air and pushes it through ducts. A boiler heats water and circulates it through radiators, baseboards, or radiant floor tubing. The result is the same idea, comfortable heat, but the way it reaches each room is very different. Boilers tend to deliver more even, gentle warmth.
Can a boiler also provide hot water for the home?
Some combination boilers handle both space heating and domestic hot water, while many homes pair a heating boiler with a separate water heater. We help you weigh which approach fits your home and your usage patterns.
How long does a boiler installation take?
A straightforward boiler replacement in a Los Gatos home is usually a one to two day project. More involved work, like a switch from atmospheric to high efficiency or significant piping updates, may take longer. We give you a clear timeline before we start.
