York heat pump service in San Antonio typically runs between $150 and $650 depending on which part failed, and we stock the most common York-compatible parts on our trucks for same-day repair. Most San Antonio homeowners discover a problem the hard way: the thermostat calls for cool air in July, the outdoor unit hums or rattles instead of starting, and suddenly a 100-degree afternoon becomes an indoor emergency. The good news is that York heat pumps are built with serviceable, replaceable components, and a failed capacitor, contactor, or defrost board doesn’t mean you need a whole new system.
Before you panic about a full replacement, understand this: heat pumps have a handful of parts that do most of the failing. Capacitors, contactors, reversing valves, defrost control boards, and fan motors account for the overwhelming majority of York heat pump service calls we run across San Antonio, from Alamo Heights to Stone Oak to the neighborhoods off Potranco Road. Andre Fuller and our crew have been diagnosing these exact failures for years, and the fix is usually faster and cheaper than homeowners expect.
Which York Models This Applies To
York heat pumps share parts across several residential series, but there’s a compatibility gotcha you should know: the Affinity series (YXV, YHM, YZH) and the LX series (YHJF, YHJR, YHE) use different control boards and reversing valve configurations than the entry-level Latitude series. If you DIY-order a board for an Affinity unit and install it in a Latitude, it will not communicate properly and you’ll have wasted a weekend and a few hundred dollars. This is the single most common parts mismatch we see when a homeowner tried to fix it themselves first.
To identify your exact York model, look on the side of the outdoor unit for the data plate. It will show a model number like YHJF36S41S1 or YZH02411. The first letters tell you the series, the two digits after tell you the capacity in thousands of BTUs (24 = 2 tons, 36 = 3 tons, 48 = 4 tons). When it comes to OEM York parts versus quality aftermarket equivalents: for capacitors and contactors, a good aftermarket part (like Titan HD or Mars) is often equal to or better than OEM, and we stock both. For control boards and reversing valves, we stubbornly stick with OEM York parts, because those components have proprietary logic and the aftermarket versions are where we’ve seen the most repeat failures.
Halden Heating and Air San Antonio is an independent service provider. We’re not affiliated with York or Johnson Controls, but we service York equipment regularly, we stock their common service parts, and we know which aftermarket equivalents actually hold up in South Texas conditions. We also keep parts on hand for Carrier, Trane, and Lennox systems, but this page is about getting your York heat pump running again.

Signs Your York Heat Pump Service Is Failing
- Outdoor unit hums but the fan doesn’t spin. This is classically a dead capacitor, the $15 part that stores the electrical burst needed to start the compressor and fan motor. San Antonio’s heat cooks capacitors, and most last 5 – 7 years before they bulge and fail.
- The system blows air, but it’s room temperature. If the indoor blower runs and the outdoor unit is silent, your contactor may have burned contacts, or the compressor itself has failed. A failed contactor is a $150 – $250 fix. A failed compressor is a bigger conversation.
- Outdoor unit runs in cooling mode but sounds like a freight train. That’s usually a worn fan motor or a failing compressor bearing. If it’s the fan motor, plan on $250 – $450 installed. If it’s the compressor, start weighing repair versus replacement.
- Unit ices up in the middle of a Texas summer. On a heat pump, ice on the outdoor coil in cooling mode means low refrigerant (which means a leak somewhere) or a failed defrost control board. The board is the cheaper fix, around $200 – $400 installed; a refrigerant leak means finding and repairing the leak, then recharging.
- System runs constantly but the house never gets comfortable. This points to a failing reversing valve (the part that lets a heat pump switch between heating and cooling) or a refrigerant charge that’s drifted low. Reversing valve replacement runs $500 – $800 installed because of the labor involved in recovering refrigerant, replacing the valve, and recharging.

AfterReplacement Cost & What’s Included
Here’s the straight breakdown for York heat pump service in San Antonio. These are installed prices, meaning the part, the labor, and the warranty are all included:
| York Heat Pump Service / Part | Typical Installed Price in San Antonio |
|---|---|
| Capacitor replacement | $150 – $250 |
| Contactor replacement | $150 – $250 |
| Defrost control board | $200 – $400 |
| Condenser fan motor | $250 – $450 |
| Reversing valve | $500 – $800 |
| Compressor replacement (3-ton) | $1,800 – $3,200 |
What drives the range? For one, the part itself. A York OEM defrost board costs more than an aftermarket equivalent, but it’s the right call. For another, accessibility: some San Antonio homes have heat pumps installed in tight side yards or on rooftops in older neighborhoods like Tobin Hill or around the Pearl District, and that changes the labor time. Every Halden job comes with a written price before we touch a tool, and every repair carries a written guarantee. If the repair fails inside the coverage window, we come back free. That’s the 365-Day Done Right Promise, and it’s the reason we stock quality parts in the first place.
DIY or Call Us?
Here’s the honest split on York heat pump service. You can safely check: your thermostat batteries, your breakers, and your air filter. A dead thermostat or a tripped breaker is free to find, and a clogged filter can cause the exact symptoms of a failing blower motor. If those check out and the unit still misbehaves, stop there.
Where DIY goes wrong: anything involving capacitors. A capacitor holds a charge even when the unit is off, and it can discharge through you. We’ve seen homeowners get knocked back from a capacitor that wasn’t properly discharged, and it’s the part that most often tempts people because it “looks easy” on a YouTube video. Anything involving refrigerant is also off-limits: by law you need EPA Section 608 certification to handle it, and a bad recharge can destroy a compressor. Our advice: if it’s not a battery, breaker, or filter, call us at (903) 623-6784 and let a trained tech with the right meter and the right parts handle it. Straight answer, written price, no runaround.
FAQs
In our experience, capacitors last 5 – 7 years in San Antonio heat, contactors 8 – 10 years, fan motors 10 – 12 years, and reversing valves 15+ years if the refrigerant charge was never abused. The compressors in well-maintained York heat pumps routinely make it 12 – 15 years, though Texas’ summer load shortens that compared to cooler climates. If your unit is older than 12 years and needs a major part, call us at (903) 623-6784 and we’ll give you honest math on repair versus replace.
Capacitors, contactors, and most single components are replace-only; they are not repairable. A defrost control board can sometimes be repaired if the failure is a burnt relay and the board is no longer available, but in 2026, most York boards are still stocked. The one honest exception is a refrigerant leak: the leaking joint can be repaired by brazing, which means the part is fixed rather than replaced. Your tech should show you the failed part before swapping it.
Most common York heat pump service, like a capacitor or contactor, is a 45 – 90 minute job on site. A defrost board swap is similar. A fan motor runs 1 – 2 hours. A reversing valve or compressor replacement is usually half a day or a full day because the refrigerant has to be recovered and recharged. We’ll give you a time window with your written quote, and you can track your tech’s arrival time on your phone.
Yes. Our trucks carry the most common York-compatible capacitors, contactors, defrost boards, and fan motors, plus aftermarket equivalents that match York specs. If we need something uncommon, like a reversing valve for a specific Affinity model, our San Antonio supply houses stock York parts same-day in most cases, and we will know before we arrive. Call (903) 623-6784 and tell us your model number; we’ll tell you if the part is on the truck or on order before we dispatch.
If your York heat pump is down in San Antonio and you want a real diagnosis, a written price, and a fix that comes with a guarantee, call us at (903) 623-6784 for a free estimate.
