Our Heating Services in Union City, California
Here is a clear breakdown of the heating work we handle and how we approach each system. The right answer for your home depends on what you already have, how it has been performing, and what you want the next 15 to 20 years to look like.
Furnace Repair
Most furnace failures fall into a handful of categories. Ignition and burner issues, blower motor problems, control board faults, safety switch lockouts, and airflow restrictions that trip high limit switches. The symptoms often look similar from the homeowner side, but each category needs a different diagnostic path. The middle of a wet, cold January is the worst time to find out a guess based repair did not hold, and a furnace that quits during a real cold stretch in Union City pushes everything else off your calendar.
Common Problems We Fix
- A furnace that turns on but blows cold air through every register
- Burners that ignite then shut off after a few seconds
- Loud bangs, rattles, or whistling when the system kicks on
- Unusual smells like burning dust, plastic, or anything sulfuric
- A blower that runs constantly and will not shut off
- Repeated lockouts that require manual resets at the unit
- Short cycling where the furnace runs for a minute and shuts off
- A pilot or ignitor failure on older units
- A thermostat that does not match what the house actually feels like
We diagnose with real instruments. Multimeters on the electrical, manometers on the gas pressure where it applies, combustion analyzers on the burner side, and visual checks on every safety. Throwing parts at a furnace is how a small repair turns into a big one. We trace the symptom back to the cause, explain it in plain language, and lay out the right fix. Most calls are solved in a single visit with parts we carry on the truck.
Furnace Installation
A new furnace is one of the longer term decisions a homeowner makes for the house. Done right, the system runs quietly for 15 to 20 years and keeps the home comfortable through every cold rain stretch we get. Done wrong, it short cycles, leaves rooms cold, and dies years early. The difference is rarely the brand on the box. It is the work behind the install.
Reasons Homeowners Choose New Installation
- An older furnace past 15 years that has lost efficiency season by season
- Repeated repair calls that have started to add up to more than the unit is worth
- A cracked heat exchanger found during a service call
- Gas bills climbing year after year with no change in usage
- A furnace that no longer keeps up during cold rain stretches
- A switch from a standard 80 percent unit to a 95 percent condensing furnace
- A remodel or addition the existing system cannot handle
- Pairing a new furnace with a matched cooling system for full HVAC replacement
- Unsafe combustion readings on an aging unit at the end of its life
Every install starts with a real heat loss calculation for the home, not a guess off the old nameplate. Oversized furnaces short cycle and waste fuel. Undersized ones run constantly and never catch up on the coldest mornings. We match the equipment to the actual house, handle venting, gas line sizing, electrical, and condensate path to current code, and finish with combustion analysis, airflow verification, and a real test through a full cycle before we walk you through the new system.
Boiler Repair and Installation
Boilers are less common in Union City than forced air, but the homes that have them tend to keep them for decades. Hydronic heat is quiet, comfortable, and reliable when the system is set up correctly and looked after. When something goes wrong, you want a heating company that actually understands these systems. Pressure issues, leaks at zone valves and circulator pumps, kettling from sediment buildup, and ignition problems on older units all show up on calls we run every winter.
Common Problems We Fix
- No heat coming through radiators or hydronic floor zones
- Pressure dropping below normal or climbing too high on the gauge
- Visible water leaks at the boiler body, valves, or circulator pumps
- Loud kettling, banging, or knocking during operation
- Pilot or ignition problems on older gas units
- One zone heating fine while another stays cold
- An expansion tank that has waterlogged or failed
- Repeated boiler lockouts that require manual resets
- Rusty or discolored water from a bleed valve when serviced
For repairs we look at the whole system rather than chasing the loudest symptom. A pressure drop usually means a leak somewhere. The leak might be at a valve, a pump seal, a radiator fitting, or in the piping. We check, we test, and we trace it back. For new installs we size the boiler based on a proper heat loss calculation, run modern piping where the old runs are too tired to trust, set proper venting, and bring everything up to current code before startup.
Heat Pump Installation and Repair
Heat pumps have changed the heating conversation for a lot of Union City homeowners. Our mild winters are exactly the climate where modern cold climate heat pumps shine, delivering efficient heating without the deep cold that challenges them elsewhere. A heat pump handles both cooling and heating from a single system, which simplifies the equipment in the home and often cuts the total energy load significantly. For homeowners moving toward all electric setups or taking advantage of efficiency incentives, heat pumps are increasingly the smart move.
Common Heat Pump Calls We Handle
- New installation in homes converting from gas furnace plus AC to all electric
- Replacement of aging air source heat pumps that have lost efficiency
- Cold air blowing from registers when the system should be heating
- Ice buildup on the outdoor unit during cooler weather
- Auxiliary heat strips running constantly because the primary stage is failing
- Refrigerant leaks that compromise both heating and cooling performance
- Defrost cycles that no longer clear ice from the outdoor coil
- Communication faults between indoor and outdoor units
- Pairings with ductless mini split heads for room by room control
Heat pump work calls for careful sizing because the system handles two seasons rather than one. We do a real load calculation for both heating and cooling, plan the line set routing cleanly, and pull a proper vacuum before charging refrigerant. For repairs, we diagnose with gauges and the manufacturer documentation rather than guessing. A heat pump installed and serviced correctly is one of the quieter, more efficient ways to keep a Union City home comfortable year round.
Why Union City Homeowners Choose Union City Plumbing and Air Pros
Plenty of HVAC companies will show up and swap a part. Here is what makes the experience different when our truck pulls into your driveway.
Real Diagnostics, Not Guesswork
Heating systems produce symptoms that point to one part when the actual failure is somewhere else. A short cycling furnace might be a flame sensor or a clogged filter. A boiler losing pressure might be a relief valve or a leak at a zone valve buried in the wall. A heat pump blowing cold air might be a reversing valve, low refrigerant, or auxiliary heat that has failed. We diagnose with instruments and explain what we find in plain language. A homeowner near Kennedy Park called us last winter after another company had replaced a control board on an older furnace twice in three months. The actual problem was a pressure switch sticking on cold starts. One correct repair and the system finished the season.
Honest Conversations About Repair vs Replace
A 12 year old furnace with a failed ignitor is one conversation. A 19 year old furnace with a cracked heat exchanger is a different one. A 25 year old boiler with a failing circulator pump is something else again. We give you the real math instead of a sales pitch. If repair makes sense, we tell you. If replacement is the smarter call given age, repair history, and safety, we explain why.
Trucks Stocked for First Visit Repairs
A repair call where the technician has to leave for parts is half a job. We stock the components that fail most often on real Union City heating systems. Ignitors, flame sensors, pressure switches, capacitors, blower motors, common control boards, gas valves where applicable, zone valves, and circulator pumps where they make sense. When a special order part is genuinely needed, we are straight about the timeline.
Skilled Install Work Done to Code
The difference between a heating system that runs strong for 20 years and one that struggles from the start is almost always in the install. Proper venting routed with the right materials. Correct gas line sizing for the BTU demand. Tight electrical at the disconnect and the controls. Real condensate routing on condensing units. A return air path that gives the system the air it needs. We do not skip the parts of an install that homeowners never see, because those are the parts that determine how the equipment performs.
Local Knowledge That Adds Up
We have worked on heating equipment in nearly every type of home in this city. Older properties in Decoto with original ductwork in tight crawlspaces, condos near BART with rooftop or closet placements, larger homes along Mission Boulevard with hydronic systems, and light commercial spaces along Whipple Road. That repeat exposure means fewer surprises during your call.
Our Service Process
Working with us is straightforward, whether you are calling about a repair, planning a replacement, or thinking about a heat pump conversion. Here is what to expect.
Step One: The Phone Call
You tell us what is happening. We ask focused questions about the symptoms, the age of the system, and how long the issue has been going on. We give you a real time window we will actually hit. If it is a true cold weather emergency, we move ahead of the standard schedule.
Step Two: On Site Diagnosis or Assessment
For repairs, we run a real diagnosis with our instruments. For installs, we walk the home, take measurements, and look at the existing equipment, ducts, venting, and gas or electrical supply. We do not rush this step because it is what makes the rest of the job go cleanly.
Step Three: Clear Recommendations
We come find you and explain what we found in plain language. If there is one clear path, we walk you through what it involves. If there are options, we lay them out with the real tradeoffs. You decide what fits your home and your timeline.
Step Four: Skilled Work and Walkthrough
We complete the repair or installation, test the system under real operating conditions, and confirm the readings are where they should be. Then we walk you through what was done, what to watch for, and how to get the most out of the equipment. We clean up before we leave.

Professional Heating Repair vs DIY Attempts
There is a place for homeowner maintenance. Changing filters on schedule, vacuuming the registers, clearing dust off return grilles, and replacing thermostat batteries are all reasonable Saturday tasks. The line gets crossed when a real failure happens and someone tries to handle it with a search engine and a borrowed multimeter.
The most common DIY mistakes we see across Union City heating systems involve homeowners replacing ignitors or flame sensors without checking why the original failed, swapping control boards on a furnace with an underlying airflow problem that fries the new board the same way, topping off boiler pressure without finding the leak that caused the drop, running a heat pump in low refrigerant condition until the compressor dies, working on gas connections without combustion analysis, and installing thermostats with wiring that does not match the actual equipment. Each shortcut shows up later as a bigger failure that costs more to fix than the original problem.
The gas side is where the most serious risks live. A furnace or boiler that is not venting properly can produce carbon monoxide. A gas connection that has been disturbed during a DIY repair can leak. A burner that is running off because of an underlying issue can produce soot, damage the heat exchanger, and shorten the life of the unit. Cracked heat exchangers from related issues are a serious safety problem, not a minor maintenance item. 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.
Hiring professionals for heating work means the diagnosis is correct, the repair addresses the actual cause, the gas and electrical sides are handled with the right materials, and the system gets tested under real operating conditions before we leave. It also means a single point of contact if anything needs adjustment later.

Frequently Asked Questions
How fast can you respond to a no heat call?
For true emergencies inside Union City we usually arrive same day, often within a few hours. We answer the phone around the clock during the heating season, and a real person picks up. Households with infants, older adults, or anyone with breathing conditions get priority dispatch.
How long should a furnace or boiler last?
A well maintained furnace in this area typically lasts 15 to 20 years. A well maintained boiler often runs 20 to 30 years. The mild winters around Union City help both, since the systems do not run as hard as they would in colder climates. Regular maintenance and yearly tune ups add years to the equipment.
Is a heat pump a good choice for my home?
For many Union City homes, yes. Our mild climate is well suited to modern heat pumps, which handle both heating and cooling efficiently. Whether it makes sense for your specific home depends on your existing equipment, electrical capacity, and goals around all electric or efficiency incentives. We walk through it honestly.
What size heating system does my home need?
That depends on more than square footage. Insulation, window exposure, ceiling heights, ductwork condition, and how each room is used all factor in. A single story in Decoto with original windows has different needs than a tight newer townhome near BART. We run a real heat loss calculation rather than guessing.
Should I switch to high efficiency?
For many Union City homes, yes. A standard 80 percent furnace loses a fifth of the fuel it burns. A modern 95 percent condensing unit captures most of that heat instead. The gas bill savings over a 15 to 20 year furnace life often add up to meaningful money. Whether the upgrade fits depends on venting and gas line conditions.
Why is my furnace blowing cold air?
A furnace that runs but blows cold air usually means burners are not lighting, the ignitor or flame sensor has failed, the gas valve is not opening, or a safety switch has tripped. Sometimes it is a thermostat set wrong or a heavily clogged filter cutting airflow enough to trip a high limit switch. We diagnose in a logical order so the right repair happens the first time.
Why is my boiler losing pressure?
Pressure loss almost always means a leak somewhere in the system. The leak might be at a circulator pump seal, a zone valve, a radiator fitting, a relief valve, or in the piping. Sometimes it is a failing expansion tank. We trace the cause rather than just topping off the pressure, because the root issue always comes back.
How often should I service my heating system?
Once a year, ideally in the fall before the first cold rain stretch. A yearly service includes a check of the burner and heat exchanger or boiler body, combustion analysis on gas units, electrical inspection, filter replacement on forced air systems, and a real test of every safety. Small problems caught during a tune up almost always cost less than the emergency repairs they prevent.
Is there a heating company near me that handles weekends and emergencies?
Yes. We run weekend and holiday heating calls across our service area regularly. Equipment failures do not respect business hours, and our team does not either. The same number you call on a Tuesday afternoon reaches us on a Sunday morning.
Can I pair a new furnace with a new AC at the same time?
Yes, and pairing the two is often the smarter way to upgrade. The labor overlaps, the equipment can be matched for best efficiency, and you only deal with one project instead of two. For Union City homeowners moving from older split systems to modern equipment, the combined approach usually makes the most sense.
Do you handle commercial heating systems?
We do. Restaurants, small offices, and multi unit residential along Whipple Road, Alvarado Niles, and Mission Boulevard often run larger or more complex heating equipment. We service both residential and light commercial heating systems.
What kind of follow up do you offer after an install?
We stay available. If anything about the new system feels off in the first weeks, you call us and we come back. We also recommend a yearly tune up to keep the equipment running strong, and we set those up on a schedule that works for you.
