Rheem heat pump service in Hempstead typically runs $150 – $650 installed, depending on what failed and whether the part is a common wear item or a major component like a reversing valve or compressor. We stock the most common Rheem service parts on our trucks, so most repairs in Hempstead are done the same day we show up. If your system is blowing warm air in cooling mode, short-cycling, icing over, or simply not turning on, you’re probably reading this page because a specific part gave out and you want to know what it costs to fix it right.
Most homeowners find us after a specific symptom: the outdoor unit hums but the fan won’t spin, or the system runs constantly without reaching set temperature. That’s the capacitor, contactor, defrost control board, or reversing valve. The part name matters less than getting it matched to your exact model, priced in writing, and installed by someone who won’t be back a second time because the first repair was a guess.
Key takeaways:
- Rheem heat pump repairs in Hempstead run $150 – $650 installed, parts and labor included.
- We stock common Rheem service parts on the truck: capacitors, contactors, defrost boards, and motors.
- Every repair is priced in writing before we start, and guaranteed in writing for a full year.
- We service all Rheem residential heat pump series, from 1970s units still limping along to current RP14/RP15/RP16 lines.
Which Rheem Models This Applies To
We service every Rheem heat pump series found in Hempstead homes. That includes the current RP14, RP15, RP16, and RP17 lines, the older RPNL and RPNK series from the 2000s and 2010s, and the genuinely old RPGB and RPKA units that show up on blocks around Hempstead Lake State Park where homes were built in the 1950s and 1960s. A Rheem heat pump’s model number is printed on the data plate on the side of the outdoor unit, typically starting with “RP” followed by numbers and letters. That plate also lists the exact refrigerant type, electrical specs, and factory charge, which matters when we’re matching a motor, board, or valve to your specific unit.
One Rheem-specific gotcha: the defrost control board changed pin configurations between the RPNL and RP14 generations. A board that looks identical from five feet away won’t plug into the older harness. That’s why we ask for the full model and serial number before we quote any electronic part over the phone. On motors, Rheem uses several different RPM ratings and mounting patterns across the RP lines, so we don’t guess. We match by the replacement part number on the motor label, not by the unit model alone.
For the OEM-versus-aftermarket question: we use OEM Rheem parts when the repair involves a control board, sensor, or anything that talks to the thermostat. For motors, capacitors, and contactors, we carry quality aftermarket equivalents that match or exceed the original spec, because an OEM motor for an older Rheem unit can take two weeks to arrive from Rheem’s distribution network while an equivalent ECM motor is in our truck today. The decision comes down to availability, compatibility, and whether your warranty still applies. We’ll tell you which path makes sense before any work begins. Dalton Heating & Air Hempstead is an independent service provider, not affiliated with the Rheem brand itself.

Signs Your Rheem Heat Pump Service Is Failing
- Outdoor unit hums but the fan won’t turn. That’s almost always the run capacitor. Heat pump capacitors weaken from heat exposure and power surges, and a failed one means the compressor or fan motor can’t start. If you hear a hum for 15-20 seconds followed by a click, the capacitor is likely dead.
- System blows cold air in heating mode or warm air in cooling mode. The reversing valve is the part that switches a heat pump between heating and cooling by redirecting the refrigerant flow. When it sticks or its coil fails, the system pumps heat the wrong direction. This is a Rheem-specific repair that requires recovering refrigerant, brazing in a new valve, and recharging to factory spec.
- Outdoor unit is covered in ice in winter, even after the defrost cycle should have cleared it. Heat pumps frost over in cold weather, but the defrost control board and defrost thermostat are supposed to clear that ice automatically. When the board fails, the coil freezes solid and the system loses heating capacity. Hempstead winters with moisture off the Atlantic make this a common failure around here.
- Unit short-cycles: turns on, runs for two or three minutes, shuts off. Usually a failing contactor, a dirty or dead defrost sensor, or low refrigerant tripping the low-pressure switch. Short-cycling is hard on the compressor and a repair bill that gets worse the longer it’s ignored.
- System runs but never reaches set temperature, and your electric bill is climbing. Low refrigerant from a slow leak means the heat pump runs longer to move the same amount of heat. In Hempstead’s humid summers and cold winters, a system running 30-40% more than it should is a sign of a leak at a Schrader valve, coil joint, or the reversing valve body itself.

AfterReplacement Cost & What’s Included
Here’s where your Rheem heat pump repair in Hempstead actually lands, installed:
- Capacitor or contactor: $150 – $300 installed. We carry these on every truck.
- Defrost control board or defrost thermostat: $250 – $450 installed, depending on your model generation.
- Condenser fan motor: $350 – $550 installed. ECM motors run higher; PSC motors run lower.
- Reversing valve: $550 – $650 installed. This is a half-day job: refrigerant recovery, valve replacement, pressure test, and recharge to the exact factory charge on your data plate.
- Compressor: $650 and up, but on a Rheem unit older than 12 years, we’ll usually show you the numbers for a full system replacement before you spend that on a compressor on borrowed time.
The price we quote is the price you pay. It’s in writing before we start, includes parts, labor, and any refrigerant needed, and it doesn’t change at the door. Every repair carries our full-year written guarantee: if that part fails within 365 days, we return and make it right at no charge. That’s The Garrison Standard, and it applies to every job we do in Hempstead, no exceptions.
DIY or Call Us?
Here’s the honest split. You can safely check three things: your thermostat settings, your breaker panel (a tripped double-pole breaker is common and simple to reset once), and your air filter. A clogged filter restricts airflow and causes real symptoms, including icing and short-cycling. Beyond that, this is where DIY goes sideways on a heat pump. A capacitor holds a stored electrical charge that can knock you down even with the power off. Refrigerant lines are under pressure, and releasing refrigerant is illegal and dangerous. The reversing valve and defrost board work with high voltage, fine wiring, and factory-programmed logic that you can’t improvise around. If you’ve checked the filter and the breaker and the system is still down, call (516) 559-4840. We’ll diagnose it, show you the failed part, and put the fix in writing before any work starts.
How Long Does a Rheem Heat Pump Last in Hempstead?
A Rheem heat pump in Hempstead’s climate typically lasts 12 – 15 years before major component failures become a regular occurrence. The salt air off the Atlantic and the humidity work on outdoor coils, and units near the south shore of Long Island see more corrosion than inland units. Regular service extends that lifespan, but after year 12, a compressor or reversing valve failure should trigger a repair-versus-replace conversation, not an automatic fix.
Can the failed part be repaired instead of replaced?
No. Capacitors, contactors, control boards, thermostats, and motors are replaced, not rebuilt. These are sealed electrical components. There is no meaningful repair to do inside them, and any tech who claims to “refurbish” a capacitor is wasting your time. We replace with new parts and stand behind them for a year.
How long does the repair take?
Capacitors, contactors, and defrost sensors take under an hour once we’re on site. Defrost boards take about an hour with testing. Fan motors run closer to two hours. A reversing valve is a half-day because it involves refrigerant recovery and the full recharge cycle. We tell you the expected window before we start, and it’s in the written quote.
Do you stock Rheem parts or do I have to wait?
We stock the common Rheem service parts on our trucks: capacitors, contactors, defrost boards for current RP14/15/16 series, and universal ECM fan motors. Oddball parts like a specific reversing valve for a 2006 RPNL can take a day or two from our parts supplier. If you call (516) 559-4840 with your model and serial number, we’ll tell you before we schedule whether the likely part is on the truck or needs to be pulled from the supplier.
Marco Benitez put it simply when a homeowner in Hempstead asked about a repair on a 1988 heat pump that had somehow outlasted two administrations: “Tell me the problem, I’ll tell you the fix and the price, then you decide.” That’s how we work. Call (516) 559-4840 and you’ll get a live person, a straight answer, and a written price before any work begins. We also service Carrier, Trane, and Lennox systems if your Rheem is one of several units on the property.
