Air Conditioning Repair
AIR CONDITIONING REPAIR IN PASADENA, CA
A healthy central air conditioner usually drops air temperature about 15 to 20 degrees between the return grille and the supply registers, so a smaller split is often the first sign that something is failing. Performance Plumbing, Heating & Air Conditioning, Inc. handles air conditioning repair in Pasadena, CA, Alhambra, CA, and Altadena, CA, restoring cooling on units that blow warm, freeze up, leak water, or refuse to start. Our 40+ years in the trade mean faster answers, and every repair is priced upfront before work begins. We also check the coil, drain, and electrical parts that heat stresses first, so the repair holds through the rest of summer.
COOL AIR RETURNS WHEN THE REAL FAULT IS FOUND.
An air conditioner that stops cooling may have a failed capacitor, a burned contactor, a refrigerant leak, a dirty condenser coil, or a frozen evaporator. Each needs a different fix. We measure pressures, temperatures, and electrical readings to locate the fault before recommending anything. Refrigerant, for example, only runs low when there is a leak somewhere in the system.
That careful approach restores cooling quickly and avoids paying for refrigerant or parts that do not solve the problem. You also leave the visit knowing exactly what failed and how to keep it from happening again.

AIR CONDITIONING REPAIR
KEEP PASADENA SUMMERS COMFORTABLE INDOORS.
August afternoons in Pasadena average close to 89°F, and heat waves push far higher, which is exactly when neglected air conditioners give out. We keep our repair process focused and efficient so your home cools down as soon as possible. Most common failures, including capacitors, contactors, and condenser fan motors, can be repaired on the first visit, and we explain every finding so you understand what happened and how to prevent it.
ATTIC HEAT AND SANTA ANA DUST ARE HARD ON CONDENSERS.
Homes around the San Gabriel Valley range from older bungalows with attic ductwork to newer houses with high-efficiency split systems. Attic heat, dusty Santa Ana winds, and long summer run times all stress outdoor condensers and indoor coils differently. We factor those local conditions into every repair, checking the coil, the airflow, and the electrical parts that summer heat wears out fastest.
WE HAVE HEARD EVERY NOISE A CONDENSER CAN MAKE.
Clicking, buzzing, grinding, and silence all tell us something specific. Our 40+ years of cooling repairs have taught us to connect those sounds with the parts behind them, which shortens the time between arrival and relief. We still confirm everything with meters and gauges before recommending a repair, because an accurate diagnosis is the only way to protect your money and your comfort. Is your AC acting up today?
WHAT A RELIABLE AC REPAIR DELIVERS.
Cooler Rooms Faster
Accurate diagnosis on the first visit means your home starts cooling again sooner, often the same day, instead of waiting through repeated appointments while the afternoon heat builds.
Protected Compressor
Replacing a weak capacitor or failing fan motor early keeps strain off the compressor, preventing the kind of damage that can turn a modest repair into a replacement.
Better Humidity Control
A properly charged system with clean coils removes moisture as it cools, so rooms feel crisp and comfortable rather than cool but clammy on humid summer evenings.
Steadier Energy Costs
An air conditioner running at its designed efficiency reaches the thermostat setting faster and cycles off sooner, which keeps summer utility bills from creeping upward each month.
Quieter Operation
Worn fan motors, loose panels, and failing contactors create noise that gets worse over time. Repairing them restores the quiet, steady hum you expect from a healthy unit.
Confidence Through Summer
After a thorough repair and test run, you can head into the hottest weeks knowing your system has been checked from the thermostat to the outdoor condenser.
our services
OUR AIR CONDITIONING REPAIR WORK.
We repair central split systems, package units, and air handlers of most major brands, focusing on the components that fail most often during long Southern California cooling seasons. Most repairs finish on the first visit.
NO START
Capacitor Replacement
Swollen or weak capacitors stop compressors and fan motors from starting. We test capacitance against the rating, install a correctly matched replacement, and verify that every motor starts smoothly and draws normal amperage.
OUTDOOR UNIT
Condenser Fan Motor Repair
When the outdoor fan stops, pressures climb and the compressor overheats. We diagnose the motor and its capacitor, replace failed parts, and confirm the fan moves enough air across the coil.
FROZEN COIL
Evaporator Coil Thaw and Repair
Ice on the indoor coil usually signals low airflow or low refrigerant. We safely thaw the coil, identify the underlying cause, and correct it so freezing does not happen again next week.
LEAK HUNT
Refrigerant Leak Detection
We use electronic leak detectors and pressure testing to find where refrigerant escapes, repair the leak point, and recharge to specification instead of adding refrigerant that will simply leak out again.
POWER SIDE
Contactor and Wiring Repair
Pitted contactors, loose terminals, and heat-damaged wires cause intermittent cooling and burned components. We repair the electrical path so power reaches the compressor and fan cleanly and reliably every time the thermostat calls for cooling.
DRIPS INSIDE
Condensate Leak Repair
Water around the indoor unit usually means a clogged drain line, cracked pan, or failed pump. We clear the drain, test the safety switch, and stop the leak before ceilings or floors suffer damage.

FAQ
FREQUENTLY ASKED QUESTIONS.
These answers cover the cooling problems homeowners ask about most, including warm air, frozen coils, strange noises, and how to tell whether a struggling air conditioner is worth repairing.
Why Is My Air Conditioner Blowing Warm Air?
Warm air usually points to a failed capacitor, a tripped breaker or disconnect, a dirty condenser coil, or low refrigerant from a leak. Check the thermostat setting and filter first, then call for testing if cooling does not return.
Why Is There Ice On My AC Lines Or Coil?
Ice forms when the evaporator coil gets too cold, usually from restricted airflow or low refrigerant. Turn the cooling off and run the fan to thaw it, then have the cause diagnosed so the freeze does not return.
Should I Keep Running My AC If It Is Making Strange Noises?
Turn it off and schedule a diagnosis. Grinding, screeching, or loud buzzing can mean a failing motor or electrical fault, and running the unit longer may damage the compressor, turning a manageable repair into something much more expensive.
How Often Should An Air Conditioner Need Refrigerant?
Never, under normal conditions. Refrigerant circulates in a sealed loop and is not consumed. If your system needs more, it has a leak, and adding refrigerant without repairing the leak only postpones the next breakdown and wastes money.
Why Does My AC Run Constantly Without Reaching The Set Temperature?
Constant running often means the system cannot keep up because of dirty coils, low refrigerant, leaky ducts, or equipment that is undersized for the home. During extreme heat, some extended run time is normal, but steady losses deserve inspection.
What Is A Normal Lifespan For A Central Air Conditioner?
Most central air conditioners in Southern California last about 12 to 15 years with regular maintenance. Units near the end of that range with major failures, such as a compressor or coil leak, often justify comparing repair costs against replacement.
