Goodman heat pump service in Santa Clarita typically runs $150 – $650 installed depending on the part, and we carry the most common Goodman components on our trucks so we can usually finish the job in one visit. Most owners find out a part has failed the same way: the outdoor unit runs, the indoor fan blows, but the air isn’t warm (or cool) enough, or the system trips its breaker on a hot afternoon. Our crew has been pulling up to Santa Clarita driveways long enough to know which Goodman parts fail first in this valley’s summer heat and winter cold snaps, and we price every repair in writing before the first bolt turns.

We’re not a Goodman dealer, and we’re not affiliated with Goodman. Dalton Heating & Air Santa Clarita is an independent service company, which means we stock compatible Goodman parts – OEM factory replacements and proven aftermarket equivalents – and install whichever makes sense for your unit, your budget, and how long you plan to stay in the house. We also service Carrier, Trane, Lennox, Rheem, York, Daikin, Bryant, and American Standard heat pumps, so if you’ve got a mixed system, one call covers it.
Which Goodman Models This Applies To
We service the full Goodman heat pump lineup: the GSZ, GSX, and GPH split-system series, plus the DSZC and GSZC two-stage units, and the self-contained packaging units found on many Santa Clarita townhomes. If your condenser label says Goodman or Amana (same parent company, Daikin), we can pull the service manual and match the part.
Here’s the compatibility gotcha most homeowners don’t know: Goodman has used at least three different defrost control board revisions across the GSZ14 and GSZ16 lines, and the boards are not interchangeable between revisions even though they look nearly identical from the outside. The wrong board will fit the bracket and then misread the coil temperature sensor, which causes the unit to defrost on a schedule that doesn’t match actual frost conditions. As owner and lead tech, Marco Benitez checks the board revision number against the unit’s serial number before ordering the replacement part, which is the difference between a repair that holds and a callback two weeks later.
On compressor swaps: Goodman uses Copeland scroll compressors on most 13+ SEER heat pumps, but the GSZ13’s first-year production units ran a piston metering device while later ones switched to a thermal expansion valve (TXV). You can’t just bolt in a new compressor and assume the metering setup matches; if the TXV or piston gets swapped incorrectly, your efficiency drops and the compressor works harder than it should. We verify the orifice size or TXV spec against the model plate every time.
Styles & brands we work with







Signs Your Goodman Heat Pump Service Is Failing
- Warm air in summer, cool air in winter (or vice versa). This usually means the reversing valve isn’t shifting. The reversing valve is what tells the system whether to heat or cool; when the solenoid coil fails, the valve sticks in one position. Good news: the coil itself is a $90 – $180 part and is a same-day fix on most Santa Clarita calls.
- Outdoor unit runs, but the air isn’t as warm or cool as it used to be. This points to a compressor or metering device problem, not a refrigerant leak. A heat pump compressor that’s worn will still spin, but it can’t move refrigerant at the pressure differential the system needs. We test the compressor’s amp draw against the Goodman spec sheet before condemning it.
- Unit short-cycles every few minutes. In Santa Clarita, this often traces back to a failed start capacitor or run capacitor, especially after a heat wave puts extra thermal load on the capacitor’s dielectric. Goodman capacitors are a common fail item in this climate; the part runs $15 – $60, and the install is quick.
- Frost building on the outdoor coil in daylight (when it’s above 40°F outside). A failed defrost control board or defrost thermostat causes the coil to stay frosted and the system to burn electricity without delivering heat. The board swap is the fix, and it’s one of the most common Goodman-specific repairs we do in Santa Clarita.
- Breaker trips only when the system runs in heating mode. This can mean the reversing valve isn’t moving and the compressor is dead-heading, or the outdoor fan motor is drawing too many amps after years of Santa Clarita valley dust builds on the windings. Either way, a breaker that pops once means you’re on borrowed time; twice means stop running it and call.

AfterReplacement Cost & What’s Included
Here’s the honest dollar picture for Santa Clarita, based on what we write up on paper every day:

- Defrost control board: $180 – $320 installed. Part cost is the range here, since Goodman boards vary by revision.
- Reversing valve solenoid coil: $90 – $180 installed. Full reversing valve (rarely needed): $500 – $800 installed.
- Start or run capacitor: $120 – $200 installed. Single capacitor, quick swap.
- Outdoor fan motor: $280 – $450 installed. The motor itself is $120 – $220; the rest is labor, and Goodman OEM motors are worth the premium here.
- Compressor (with filter-drier replacement and R-410A recharge): $1,800 – $3,200 installed. We only recommend compressor replacement when the unit is under ten years old; beyond that, you’re usually better off replacing the entire heat pump.
That price includes the part, the labor, the refrigerant (if needed), and a written guarantee on the repair for a full year. If the part fails in that window, we come back at no charge – no diagnosis fee, no parts fee, no “well, this failure is different” language. That’s The Garrison Standard, and it’s been that way since 2003.
DIY or Call Us?
You can safely change a filter or clear leaves away from the outdoor coil. Some homeowners can replace a capacitor if they’re comfortable with basic electrical work, but note that even after you kill the breaker, a capacitor can hold a charge that will ruin your afternoon. If you don’t own a multimeter and know how to discharge a capacitor safely, that’s the line where DIY stops being cheaper and starts being dangerous.
Everything else on a Goodman heat pump is not a DIY job: compressors run on 208/230-volt circuits, reversing valves are brazed into the refrigerant line, and an improper refrigerant charge will destroy a new compressor in months. Santa Clarita’s hot summers mean any mistake gets magnified when the system runs at full load. Price on paper before the first bolt turns – that’s how we work. If you’re not sure whether your problem is a $30 capacitor or a $2,000 compressor, call (661) 621-3712 and we’ll diagnose it for a flat service fee before recommending anything.
FAQs
Capacitors last 3 – 7 years in Santa Clarita’s summer heat; defrost control boards 5 – 10; compressors 10 – 15 with clean coils and regular filter changes; outdoor fan motors 8 – 12. What kills parts early here is the valley’s dust combined with 100°F+ run cycles.
Capacitors, contactors, and reversing valve coils are replace-only parts – there’s no meaningful repair. For most electronics (defrost boards, thermistors), the labor to troubleshoot and solder a board exceeds the cost of a new board, so replacement is the smart money. We’ll tell you if repair is ever the better option, but on Goodman heat pumps it rarely is. Call (661) 621-3712 for a straight answer on your specific part.
Capacitor or coil swaps are 45 – 60 minutes. Defrost board replacement is 60 – 90 minutes. Outdoor fan motor is 1.5 – 2 hours. Compressor replacement is a 4 – 6 hour job including pump-down, brazing, and recharge. We give you a real arrival window and stick to it.
We stock the common fail items – capacitors, contactors, reversing valve coils, defrost boards for the GSZ14/16 lines, pressure switches, and thermistors – on our Santa Clarita service trucks. Rare or model-specific parts (a specific compressor, a specific fan motor) we source same-day from our local supplier or next-day from Goodman distribution. Either way, you get a written price before we touch anything.
