Furnace Maintenance
FURNACE MAINTENANCE IN PASADENA, CA
The CDC reports that more than 400 people in the United States die from unintentional carbon monoxide poisoning each year, and fuel-burning appliances such as furnaces are among the common sources when venting or combustion goes wrong. Performance Plumbing, Heating & Air Conditioning, Inc. provides furnace maintenance in Pasadena, CA and the surrounding San Gabriel Valley, cleaning burners and flame sensors, testing igniters and safety switches, measuring gas pressure, and inspecting venting and heat exchangers. Guided by 40+ years in heating, we deliver a written report after every visit with honest recommendations and no pressure. Most tune-ups take about an hour from start to finish.
CLEAN BURNERS MAKE A SAFER, CHEAPER FURNACE.
Furnaces in Pasadena sit idle for most of the year, collecting dust on burners, sensors, and blower wheels. When the first cold night arrives, that buildup causes failed ignition, short cycling, and inefficient heating. A pre-season tune-up clears it away and confirms every safety device still responds correctly. A dusty flame sensor alone accounts for many winter calls.
Maintenance costs far less than an emergency call, and it protects the most important part of the furnace: its heat exchanger. That protection alone makes the yearly visit worthwhile.

FURNACE MAINTENANCE
BE READY BEFORE PASADENA'S FIRST COLD SNAP.
Cold weather in Pasadena tends to arrive suddenly, with a warm October giving way to chilly November nights. Scheduling furnace maintenance in September or October means your system is tested, cleaned, and ready before demand peaks. Our technicians work through a detailed checklist while also paying attention to the subtle signs, such as a lazy flame, rust near the vent, or a slow inducer start, that often appear months before an actual breakdown occurs.
SHARED VENTS AND DECADES OF CHANGES DESERVE A CLOSER LOOK.
Many furnaces around the San Gabriel Valley live in garages and attics where dust, heat, and debris build up during summer. Some share vents with water heaters, and older homes may have venting that was modified over the decades by different contractors. Every maintenance visit includes a careful look at the vent path, combustion air supply, and nearby gas connections that affect how safely the furnace operates in your specific home.
SMALL READINGS TELL US BIG THINGS ABOUT A FURNACE.
A flame sensor signal slightly below normal, a temperature rise a few degrees too high, or gas pressure just off specification can each predict a failure before it happens. Our 40+ years of furnace work taught us to pay attention to those small numbers and track them from year to year. We explain what the readings mean, prioritize findings honestly, and never push repairs that can safely wait. Is your furnace due for its pre-winter checkup?
WHAT REGULAR FURNACE MAINTENANCE DELIVERS.
Reliable First Starts
Clean burners, a polished flame sensor, and a tested igniter mean your furnace lights on the first cold night instead of leaving you waiting for a repair visit.
Safer Home Heating
Venting inspections, combustion checks, and safety switch testing confirm your furnace removes exhaust properly and shuts down when it should, protecting everyone who lives in your home.
Lower Gas Usage
A properly adjusted furnace with clean burners and correct gas pressure converts more fuel into warmth, keeping winter gas bills lower throughout the entire heating season.
Fewer Breakdowns
Worn igniters, weak capacitors, and slipping belts are spotted and replaced on your schedule, not during a cold snap when parts and appointment times are harder to find.
Longer Heat Exchanger Life
Correct airflow and temperature rise keep the heat exchanger from overheating, which prevents the cracks that often end a furnace's life years earlier than necessary.
Documented Service History
Written maintenance records support manufacturer warranty claims and show future buyers that the heating system received consistent professional care throughout its life. We keep copies too.

OUR FURNACE MAINTENANCE WORK.
Every furnace maintenance visit follows a thorough inspection and cleaning routine designed to improve safety, reliability, and efficiency before the heating season begins in Pasadena and the San Gabriel Valley. Nothing is rushed.
BURNER CARE
Burner Cleaning and Inspection
We clean burners and check flame pattern, color, and stability. A clean, steady blue flame means efficient combustion, while yellow or lifting flames point to problems that need attention before winter arrives.
IGNITION CHECK
Igniter and Flame Sensor Service
We test the igniter's resistance and clean the flame sensor, then measure its signal. These two small parts cause most no-heat calls, so keeping them healthy prevents many winter breakdowns.
SAFETY CONTROLS
Safety Switch Testing
Limit switches, rollout switches, and pressure switches shut the furnace down when something goes wrong. We verify each one responds correctly, because a failed safety control can hide a serious problem.
EXHAUST CHECK
Venting and Draft Inspection
We inspect the vent pipe for proper slope, secure joints, corrosion, and blockages, and confirm the inducer establishes correct draft so combustion gases leave your home safely during every cycle.
GAS PRESSURE
Gas Pressure Measurement
Incorrect manifold pressure causes weak heat, sooting, or overheating. We measure pressure with a manometer, adjust it to the manufacturer's specification, and check the gas valve for smooth, reliable operation.
AIR MOVEMENT
Blower and Filter Service
We inspect the blower wheel and motor, check the filter, and measure temperature rise across the heat exchanger. Proper airflow protects the furnace from overheating and keeps warm air moving evenly.

FAQ
FREQUENTLY ASKED QUESTIONS.
Seasonal furnace care keeps heating safe and dependable. These answers explain what a tune-up includes, how often to schedule one, and which warning signs deserve attention between routine visits.
How Often Does A Gas Furnace Need Professional Maintenance?
Once a year is the standard recommendation, ideally in early fall or late summer before regular use begins. Furnaces in dusty garages or attics, or homes with pets, may benefit from more frequent filter changes between those annual professional visits.
What Does A Furnace Tune-Up Include?
Every furnace tune-up we perform covers cleaning burners and the flame sensor, testing the igniter and safety switches, measuring gas pressure and temperature rise, inspecting venting and the heat exchanger, and checking the blower. You receive written findings afterward.
Why Does The Flame In My Furnace Look Yellow?
Healthy gas furnace flames burn mostly blue. Yellow, orange, or lazy flames can indicate dirty burners, poor combustion air, or incorrect gas pressure, all of which quietly reduce efficiency and increase carbon monoxide risk. Schedule an inspection promptly.
Can Skipping Maintenance Void My Furnace Warranty?
It can. Many manufacturers require proof of regular professional maintenance before honoring warranty claims on major components. Keeping dated service records protects your coverage and gives you documentation if a covered part fails unexpectedly during the warranty period.
What Is A Heat Exchanger And Why Is It Inspected?
The heat exchanger separates combustion gases from the air circulating through your home. Cracks allow exhaust to mix with household air, so during maintenance we check accessible areas for rust, cracks, and soot, and explain any concerns immediately.
How Often Should I Change My Furnace Filter?
Most 1-inch filters need replacement every 1 to 3 months, depending on pets, dust, and system run time. Thicker media filters can last 6 to 12 months. Check monthly during heavy use, and replace any filter that looks gray.
Do You Offer Furnace Maintenance For Older Systems?
Definitely. Performance Plumbing, Heating & Air Conditioning, Inc. maintains furnaces of all ages in Pasadena, CA. Older systems often benefit most from annual attention, since careful inspection of venting, heat exchangers, and safety controls helps them run safely for longer.

HOW WE WORK
FROM DUSTY BURNERS TO SAFE WINTER HEAT, HERE IS HOW.
STEP 01
WE BOOK BEFORE THE COLD
We schedule your visit in early fall, before heating demand peaks. That timing gives us room to handle any repairs we find while the weather is still mild and appointments are easy. Early planning helps.
STEP 02
WE INSPECT FIRST
Before cleaning anything, we observe the furnace running through a full cycle, watching ignition, flame behavior, and blower operation. That first look often reveals problems a cold, idle furnace would hide. Watching comes first.
STEP 03
WE CLEAN KEY PARTS
Burners, the flame sensor, and accessible blower components are cleaned carefully. Removing a season of dust restores reliable ignition and efficient combustion, which lowers gas use and helps prevent early failures. The difference is immediate.
STEP 04
WE TEST SAFETY SYSTEMS
Limit, rollout, and pressure switches are tested, venting is inspected, and gas pressure is measured. These checks confirm the furnace shuts down properly if something goes wrong, which is the heart of safe operation.
STEP 05
WE RECORD THE READINGS
Temperature rise, gas pressure, flame signal, and amperage readings are recorded. Comparing them year to year shows gradual changes, helping us predict problems early and plan repairs on your schedule. History reveals trends.
STEP 06
WE REVIEW FINDINGS WITH YOU
You receive a written report that explains what we found in plain language, separating urgent items from things to monitor. Any repair recommendation comes with an upfront price and no pressure to proceed.
