How much is a combined heating and cooling system?
A combined heating and cooling system typically costs $10,000 to $20,000 installed, with many homeowners landing near the middle of that range depending on home size, ductwork condition, efficiency level, and local labor rates. For your York D1NA024N05606 packaged unit, the exact total depends on the replacement type and installation scope; we use the parts list on this model page to keep repair costs down when replacement is not necessary.
What drives the total installed price
These factors usually move the price the most:
- System type: packaged unit vs. split system (AC plus furnace or air handler)
- Capacity and efficiency: higher SEER2/EER2 and higher AFUE typically cost more
- Ductwork: repairs, sealing, resizing, or full replacement
- Electrical and gas work: disconnects, breakers, gas line changes, venting
- Permits and disposal: local requirements and haul-away
- Controls and accessories: thermostat, zoning, surge protection
Typical cost ranges (installed)
| What you’re buying | Typical installed range | Best fit when |
|---|---|---|
| Repair existing packaged unit | $200 to $2,000+ | A single failed part is causing the issue |
| Replace packaged unit (like-for-like) | $10,000 to $20,000 | You want a direct replacement footprint |
| Convert to split system | $12,000 to $25,000+ | You want different equipment layout or efficiency options |
Repair-first checks that can save money
If your unit is not starting, humming, or the outdoor fan will not run, a failed run capacitor is a common, lower-cost fix.
- Shut off power at the disconnect and breaker before inspecting
- Look for a bulged or leaking capacitor (common failure sign)
- If you test, use a meter with capacitance mode and compare to the rating on the part
- Replace with the same microfarad rating and equal or higher voltage rating
- If the compressor or fan still will not run, check wiring and fuses next
For this model, we list a compatible capacitor CAP050300440RSP.
Ordering parts vs. replacing the whole system
When the unit is otherwise in good shape, replacing a failed electrical part (like a capacitor) is often the fastest way to restore heating and cooling. You can order parts from the list for York D1NA024N05606, or search by model number on Sears PartsDirect.
Why it matters
A packaged HVAC replacement price is mostly installation labor and job complexity, not just the equipment. Confirming whether you need a full replacement or a targeted repair can change the total cost by thousands.

What is an AC with both cooling and heating called?
An AC system that provides both cooling and heating is most commonly called a heat pump. In a York heating and cooling combined unit like model D1NA024N05606, the heat pump moves heat in or out of your home depending on the season, instead of creating heat the way a furnace does.
Common names you will see
- Heat pump (most common)
- Heat pump package unit (when heating and cooling are in one outdoor cabinet)
- Heating and cooling combined unit (general category name)
- Packaged HVAC unit (general industry term)
How it works (cooling vs. heating)
A heat pump uses the same core components in both modes (compressor, coils, refrigerant circuit) and changes direction with a reversing valve.
| Mode | What the system does | What you feel indoors |
|---|---|---|
| Cooling | Moves heat from inside to outside | Cooler, drier air |
| Heating | Moves heat from outside to inside | Warmer air |
Why it matters when troubleshooting
Knowing it is a heat pump helps you narrow symptoms and parts:
- If it cools but will not heat, the issue is often in the reversing/defrost controls or thermostat setup.
- If it struggles in both heating and cooling, look at airflow, electrical, or compressor circuit issues.
- A weak start or humming at startup can point to a failing run capacitor such as the capacitor CAP050300440RSP.
Quick checks we recommend before replacing parts
- Confirm the thermostat is set to HEAT (not EM HEAT) and the temperature is set above room temp.
- Replace or clean the air filter and make sure supply and return vents are open.
- Check the outdoor unit for debris blocking airflow.
- If you are comfortable using a meter, use a safe test process like how to use a multimeter to test electrical parts video.
Ordering the right part
Match parts by model number D1NA024N05606 and the exact part ID or part number shown in the parts list. You can also search by model number on Sears PartsDirect if you are sourcing additional York HVAC parts.

How do I find the model number on my D1NA024N05606?
The model number for your York heating and cooling combined unit is printed on the unit’s rating plate (data tag). On model D1NA024N05606, you will typically find that tag on the exterior cabinet near the service/access panel.
Where to look on the unit
Check these common rating-plate locations on packaged heating and cooling units:
- Outside cabinet near the electrical disconnect or control box access panel
- Inside the main service panel (you may need to remove screws)
- Near the blower compartment door or burner compartment door (gas models)
- On the side panel close to the refrigerant line entry point
- On the inside lip of a removable access cover
What the model tag looks like
The rating plate is usually a silver or white sticker or metal plate. It often includes:
- Model number (for example, D1NA024N05606)
- Serial number
- Electrical ratings (voltage, phase, MCA, MOP)
- Refrigerant type and factory charge
- Heating input/output information (if equipped)
Quick checklist to confirm you have the right number
Use this checklist before ordering parts:
- Match the model number exactly, including all letters and digits
- Copy the serial number too (it helps confirm production series)
- If the tag is worn, take a clear photo and zoom in to read it
Why it matters
York often uses similar cabinet designs across multiple series; the exact model number ensures the correct diagrams and replacement parts (such as a run capacitor) match your unit’s electrical and HVAC configuration.
Common items you may match by model
| Item you’re identifying | Where it’s used | Why the exact model helps |
|---|---|---|
| Model number | Rating plate | Ensures correct parts list and diagrams |
| Serial number | Rating plate | Confirms production series/variations |
| Electrical ratings | Rating plate | Helps match capacitors, contactors, motors |
If you’re ordering a capacitor for this unit, match your existing capacitor’s microfarad (µF/MFD) rating and voltage to the replacement listing, such as the capacitor CAP050300440RSP.
