Heat Pump Repair
HEAT PUMP REPAIR IN PASADENA, CA
A heat pump relies on a reversing valve to redirect refrigerant flow when it switches between cooling and heating, so a single stuck valve can leave a home with only one season of comfort, or none. Performance Plumbing, Heating & Air Conditioning, Inc. provides heat pump repair in Pasadena, CA, Alhambra, CA, and Altadena, CA, diagnosing reversing valves, defrost controls, compressors, capacitors, and refrigerant leaks on ducted and packaged systems. Our 40+ years in the trade help us test both operating modes thoroughly, and every repair is priced upfront before any work starts. We also clean the outdoor coil when needed, since debris reduces heat transfer in both directions.
ONE SYSTEM, TWO SEASONS, AND NO ROOM FOR GUESSWORK.
Because a heat pump cools in summer and heats in winter, it runs more hours each year than an air conditioner or furnace alone. That extra work shows up in capacitors, contactors, fan motors, and refrigerant connections. When something fails, we test the system in both modes so the repair covers the whole year, not just today.
Diagnosing both modes also reveals problems that might otherwise hide until the next season change arrives. That thoroughness usually saves you a second service call when the weather changes.

HEAT PUMP REPAIR
YEAR-ROUND COMFORT RESTORED FOR PASADENA HOMES.
Pasadena's mild winters make heat pumps an efficient choice, yet the same equipment must also handle summer afternoons near 90°F. When a heat pump struggles, homeowners often notice lukewarm air in winter, warm air in summer, or a system that seems stuck in one mode. We find the cause through methodical testing of electrical parts, refrigerant pressures, and controls, then restore dependable comfort for whichever season comes next.
DUSTY WINDS COAT OUTDOOR COILS AND COST YOU IN BOTH SEASONS.
Heat pumps across the San Gabriel Valley face dusty winds, hot attic ductwork, and long cooling seasons followed by chilly mornings. Outdoor coils collect debris that reduces heat transfer in both directions, while indoor components work hard during summer peaks. We check how local conditions have affected your specific system, clean what needs cleaning, and repair the components that year-round operation wears out fastest.
REVERSING VALVES HAVE TAUGHT US MORE THAN ANY MANUAL.
Heat pump problems can be tricky because symptoms in one mode often point to parts that matter in both. A valve stuck halfway, a failing defrost sensor, or a slow leak can mimic other faults. With 40+ years of heating and cooling repair, we recognize those patterns quickly and confirm them with testing before replacing anything. Would you like your heat pump working properly in both seasons again?
WHAT A THOROUGH HEAT PUMP REPAIR DELIVERS.
Comfort In Both Seasons
Testing both heating and cooling modes ensures your repair restores year-round comfort, so you are not caught off guard when the weather turns and the other mode is needed.
Efficient Electric Heating
A properly repaired heat pump heats with far less energy than electric resistance heat, keeping winter electricity bills reasonable while your home stays warm and comfortable.
Protected Compressor
Fixing weak capacitors, failed fan motors, and refrigerant leaks promptly keeps the compressor from overheating, preserving the most expensive part of your heat pump system.
Fewer Surprise Failures
Because we look at the whole system rather than one symptom, developing problems get addressed during the same visit, reducing repeat service calls throughout the year.
Accurate Refrigerant Charge
Heat pumps are sensitive to charge in both modes. Repairing leaks and charging to specification restores capacity and efficiency when heating and when cooling your home.
Straight Answers
You receive a clear explanation of what failed and an upfront price, along with honest advice when an aging heat pump makes replacement the smarter long-term investment.

OUR HEAT PUMP REPAIR WORK.
These are the heat pump repairs we perform most often throughout Pasadena and the San Gabriel Valley, covering the components that year-round heating and cooling operation wears out first in local homes.
MODE SWITCH
Reversing Valve Repair
A stuck or leaking reversing valve traps the system in one mode or reduces capacity. We test the solenoid and valve operation, repair or replace failed parts, and confirm smooth switching between modes.
ICE CONTROL
Defrost Board and Sensor Repair
Heat pumps periodically defrost the outdoor coil during heating. When sensors or the defrost board fail, ice builds up and heating fades. We test the controls and restore proper defrost cycles.
COMPRESSOR CARE
Compressor Diagnosis
A compressor that will not start, trips breakers, or runs hot needs careful testing. We check windings, capacitors, and electrical supply to determine whether a repair or replacement makes sense.
LEAK REPAIR
Refrigerant Leak Repair
Low charge reduces capacity in both modes and stresses the compressor. We locate leaks with electronic detection, repair them properly, and recharge the system to the manufacturer's specification afterward. Testing confirms it.
OUTDOOR FAN
Fan Motor and Capacitor Replacement
The outdoor fan moves air across the coil in every season. We diagnose weak motors and capacitors, replace failed parts, and verify the fan runs at proper speed without overheating.
BACKUP HEAT
Auxiliary Heat Troubleshooting
Many heat pumps include electric backup heat for cold mornings. When it fails or runs too often, comfort and bills suffer. We test heat strips, sequencers, and thermostat settings to correct the problem.

FAQ
FREQUENTLY ASKED QUESTIONS.
Heat pumps behave differently from furnaces and air conditioners, which creates some unique questions. These answers explain normal operation, common warning signs, and when a heat pump problem needs professional attention.
Why Is My Heat Pump Blowing Cool Air In Heating Mode?
Air from a heat pump feels cooler than furnace air, often around 90 to 95°F, which is normal. Truly cool air can mean a defrost cycle, a stuck reversing valve, low refrigerant, or a thermostat configuration problem worth checking promptly.
Is It Normal For Steam To Rise From My Heat Pump In Winter?
Yes, during a defrost cycle. The heat pump briefly reverses to melt frost from the outdoor coil, producing steam and a whooshing sound. Constant ice buildup or frequent defrosting without heat afterward, however, indicates a problem needing repair.
Why Does My Heat Pump Run Almost Constantly?
Heat pumps run longer cycles at lower output than furnaces, so extended run times are often normal. However, nonstop operation paired with weak comfort can signal low refrigerant, dirty coils, failing components, or equipment undersized for the home.
What Is Emergency Heat On My Thermostat?
Emergency heat turns on backup electric heat strips and shuts the heat pump off. It should be used only when the outdoor unit fails. Running it regularly raises electricity costs sharply, so a repair visit is the better solution.
How Long Should A Heat Pump Last?
Most heat pumps last around 12 to 16 years, somewhat less than a furnace, because they operate year round. Regular maintenance, clean coils, and prompt repairs help systems reach the longer end of that range reliably and efficiently.
Can A Heat Pump Be Repaired If It Is Leaking Refrigerant?
Often, yes. Many leaks occur at accessible fittings, valves, or coils that can be repaired. If a coil has multiple leaks or the system is very old, replacement may be more economical, and we compare both options clearly.

HOW WE WORK
FROM ONE WORKING MODE TO TWO, HERE IS HOW.
STEP 01
WE LEARN THE SYMPTOMS
You tell us whether the problem appears in heating, cooling, or both, along with any noises, ice, or thermostat messages. Those clues narrow the search and help us prepare the right parts before arrival.
STEP 02
WE TEST BOTH MODES
Our technician runs the heat pump in heating and cooling, measuring pressures, temperatures, and electrical readings each way. Comparing both modes reveals faults that a single-mode check would easily miss. Both modes matter equally.
STEP 03
WE ISOLATE THE FAULT
Using those readings, we pinpoint the failed component, whether it is a reversing valve, defrost control, capacitor, or leak. Testing confirms the diagnosis before any part is replaced or any refrigerant added. No guessing.
STEP 04
WE EXPLAIN AND PRICE
You receive a plain explanation and an upfront price. For older systems, we also discuss repair versus replacement honestly so you can make a well-informed decision without feeling rushed or pressured. Questions are welcome.
STEP 05
WE COMPLETE THE REPAIR
We replace failed components with properly matched parts, repair leaks, and correct contributing problems such as dirty coils or airflow restrictions that stressed the system in the first place. The fix lasts longer that way.
STEP 06
WE VERIFY EACH SEASON
After the repair, we operate the heat pump in both modes and confirm correct pressures, temperatures, and defrost behavior. You leave confident that the system is ready for summer heat and winter chill.
