Quick Decision Guide
Common signs you may need heat pump repair
Heating problems usually start as comfort or safety concerns before they become a full no-heat failure.
Call when you notice
- No heat, weak airflow, or rooms that stay cold even with the thermostat turned up.
- The system starts and stops repeatedly, makes unusual noises, or gives off a burning smell.
- You are dealing with a sudden failure during cold weather or a safety-related concern.
Why homeowners choose PULSE
What you can expect
- You get licensed diagnosis first, with same-day scheduling whenever availability allows.
- We explain the cause and price before work starts so there are no guesswork repairs.
- Most common repair parts are handled on the first visit when truck stock allows.
If your heating system is completely down, calling is usually the fastest way to get help.
Service details and pricing
The overview below explains how this service works, common problems we see, and what Sacramento homeowners should expect before scheduling.
Heat pumps are both your heater and your air conditioner — which means when they fail, you lose comfort in any season. PULSE HVAC technicians are trained specifically on heat pump systems, including their unique reversing valves, defrost cycles, and refrigerant management.
Common Heat Pump Problems We Repair
Heat pumps have components that standard AC-only technicians may not be familiar with. Our team handles all heat pump issues:
- Not heating in winter — Refrigerant leak, reversing valve failure, defrost board malfunction
- Not cooling in summer — Refrigerant low, compressor issue, capacitor failure
- Stuck in one mode — Reversing valve solenoid failure or control board issue
- Icing up — Defrost control malfunction or refrigerant problem
- Short cycling — Dirty filter, refrigerant undercharge, or failing compressor
- Loud noises — Grinding (bearings), squealing (fan motor), or banging (loose component)
- High energy bills — Refrigerant leak, dirty coils, or declining compressor efficiency
- Auxiliary heat running constantly — Heat pump not keeping up due to refrigerant or defrost issue
Heat Pump vs. Furnace Repair
Heat pumps require technicians with specific refrigerant certification and knowledge of the reversing valve, defrost board, and supplemental heat systems. Not every HVAC company has this experience. All PULSE technicians hold EPA 608 certification and are trained on both cooling and heating modes of heat pump operation.
Brands We Service
Carrier, Lennox, Trane, Rheem, Goodman, Daikin, Mitsubishi, Fujitsu, American Standard, Bryant, York, and most other residential and light commercial heat pump brands.
How Long Does Heat Pump Repair Take?
Most heat pump repairs are completed in a single visit. Here's what to expect for common repairs:
- Capacitor replacement — 30–60 minutes; part typically on our truck
- Refrigerant leak repair + recharge — 2–3 hours depending on leak location
- Reversing valve replacement — 3–5 hours; involves pumping down refrigerant
- Defrost board replacement — 1–2 hours; we typically have common boards in stock
- Contactor replacement — 30–45 minutes
For parts we don't carry on the truck, most are available from our local suppliers within 1–2 business days.
Heat Pump Repair vs. Replacement
For heat pumps under 12 years old, repair is almost always the right choice unless major components (compressor, refrigerant coil) have failed. For systems 12–15+ years old, we provide an honest assessment of whether repair cost justifies the remaining lifespan.
A few situations where replacement usually makes more sense:
- Compressor failure on a 12+ year old system (replacement cost often approaches the price of a new unit)
- R-22 refrigerant system (cannot be legally recharged; parts increasingly unavailable)
- Multiple failing components simultaneously
- System significantly undersized for your home
We'll tell you the repair cost and the replacement cost and let you make the call.
Sacramento-Specific Heat Pump Considerations
Sacramento's mild winters (rarely below 30°F) are excellent for heat pump heating — the mild-climate efficiency advantage of heat pumps is fully realized here. However, the intense summers (100–108°F) push heat pumps to their operational limits on peak days. Systems with dirty coils, low refrigerant, or failing capacitors are particularly vulnerable during Sacramento heat events.
