How many sq ft will a 6000 BTU AC cool?
A 6,000 BTU air conditioner typically cools about 150 to 250 sq ft in average conditions. For your York H2RA030S06D central air conditioner setup, use this as a sizing reference only; central systems are sized by the whole-home load, not a single room.
Quick sizing guide (6,000 BTU)
Use these ranges to estimate coverage for a typical room with an 8 ft ceiling.
- 150 to 250 sq ft: average insulation, average sun exposure
- 150 to 200 sq ft: hot climate, lots of sun, poor insulation, high ceilings
- 200 to 250 sq ft: shaded room, good insulation, fewer heat sources
- Reduce coverage if the room has many windows, west-facing sun, or multiple occupants
What changes the square-foot number
BTU-to-square-foot charts assume “average” conditions. These factors push you toward the lower end of the range:
- High ceilings or open floor plans
- Strong afternoon sun (south or west exposure)
- Older windows or weak insulation
- Heat-producing appliances (cooking, computers, TVs)
- More than 2 people regularly in the room
Central AC vs. room AC: what to compare
A 6,000 BTU unit is usually a small room air conditioner. A central air conditioner like the York H2RA030S06D is normally rated in tons (1 ton = 12,000 BTU/hr) and is selected using a load calculation.
| Cooling type | Typical use | How it’s sized |
|---|---|---|
| Room AC (6,000 BTU) | Single room | Room sq ft and heat load |
| Central AC (like H2RA030S06D) | Whole home | Home heat gain (Manual J style) |
Why it matters
If BTU is too low, the space stays warm and the unit runs constantly. If BTU is too high, it can cool too fast and leave the room humid and uncomfortable.
Finding the right parts for your York system
When you are ready to troubleshoot or repair your York H2RA030S06D, match parts by the exact model number and the part listing for your unit, then use Sears PartsDirect to search by model if you are comparing diagrams or looking up additional components.

How much does an AC unit cost for a 1500 sq ft house?
For a 1,500 sq ft home, a new central AC system typically costs about $4,500 to $9,000 installed, depending on efficiency (SEER2), ductwork condition, electrical upgrades, and labor rates. Your York H2RA030S06D is a central air conditioner model; sizing and install details drive the final price.
What changes the price the most
- System size (tons/BTU): many 1,500 sq ft homes land around 2 to 3 tons, but insulation, windows, and climate can push that up or down.
- Efficiency rating (SEER2): higher efficiency costs more upfront and can reduce operating cost.
- Ductwork: repairs, sealing, or replacement can add significant cost.
- Electrical and controls: disconnect, breaker/wiring, thermostat, and safety controls.
- Refrigerant line set: reuse vs. replace, plus any flushing/cleanup.
- Permits and commissioning: required in many areas and important for performance.
Typical cost breakdown (installed)
| Cost item | Common range | Notes |
|---|---|---|
| Outdoor condenser + indoor coil | $2,500 to $6,000 | Equipment cost varies by brand and SEER2 |
| Labor (remove/replace, startup) | $1,500 to $3,500 | Region and complexity matter most |
| Ductwork repairs or replacement | $0 to $4,000+ | Only if needed |
| Electrical upgrades | $0 to $1,500+ | Depends on panel capacity and wiring |
How we recommend you estimate the right size for 1,500 sq ft
A fast planning estimate is 18 to 25 BTU per sq ft (about 27,000 to 37,500 BTU, or roughly 2.25 to 3.1 tons). For accurate sizing, use a load calculation (Manual J) so the system dehumidifies well and avoids short-cycling.
Why it matters
An oversized unit can cool fast but leave humidity high and wear parts like the compressor, contactor, and capacitor sooner. A properly sized system runs longer, steadier cycles for comfort and efficiency.

What is the most expensive part to replace on an AC unit?
On a York central air conditioner like model H2RA030S06D, the compressor is typically the most expensive single component to replace because it is the main pump that circulates refrigerant through the system. In many repairs, the indoor or outdoor coil can also be a high-cost replacement.
Most expensive AC parts (typical cost ranking)
These are the components that most often drive the highest repair bills on a central AC system:
- Compressor (often the top-cost part and labor-intensive)
- Condenser coil (outdoor coil) or evaporator coil (indoor coil)
- Control board or other major electrical controls (varies by design)
- Blower motor (indoor air handler or furnace section)
- Fan motor (outdoor condenser fan)
What usually makes the repair expensive
Cost is not just the part; it is also the work required to replace it correctly.
- Refrigerant recovery and recharge (when the sealed system is opened)
- Brazing/soldering and leak checking
- Evacuation with a vacuum pump and proper commissioning
- Diagnostic time to confirm the failed component
- Accessibility (tight installs increase labor time)
Quick comparison: compressor vs. coil replacement
| Repair item | Why it is costly | Common “add-on” work |
|---|---|---|
| Compressor | Sealed-system component; high labor | Refrigerant handling, brazing, evacuation, recharge |
| Evaporator or condenser coil | Large sealed-system component; leak-prone | Refrigerant handling, pressure test, evacuation, recharge |
| Control board | High part cost on some units | Electrical diagnosis, wiring checks |
Why it matters
When the compressor or a coil fails, the repair often involves sealed-system work and refrigerant handling. That combination is what typically pushes the total cost higher than items like capacitors, contactors, or sensors.
Parts lookup tip for H2RA030S06D

What size central AC do I need for a 1500 sq ft house?
For a typical 1,500 sq ft home, we usually see a central AC size in the 2.5 to 3 ton range (about 30,000 to 36,000 BTU/hr). The right size depends on insulation, windows, ceiling height, sun exposure, and duct condition, not just square footage.
Quick sizing rule of thumb (starting point)
Use this as a planning estimate before you confirm with a load calculation:
- Well-insulated, shaded, efficient windows: ~18 to 22 BTU/sq ft
- Average insulation and windows: ~22 to 25 BTU/sq ft
- Hot sun, older windows, weaker insulation: ~25 to 30 BTU/sq ft
For 1,500 sq ft, that works out to roughly 27,000 to 45,000 BTU/hr (about 2.25 to 3.75 tons). Most homes land near the middle.
What can push the size up or down
These factors commonly change the tonnage recommendation:
- Climate zone and humidity (hotter or more humid usually needs more capacity)
- Ceiling height (tall ceilings increase the air volume you must cool)
- Window area and direction (large west-facing glass adds heat load)
- Insulation and air leaks (attic insulation and sealing matter a lot)
- Ductwork condition (leaks or undersized ducts reduce delivered cooling)
- Occupancy and heat sources (more people, cooking, electronics)
Why “bigger” is not better
An oversized central air conditioner can cool the air too quickly and shut off before it removes enough moisture. That often leads to clammy comfort, more cycling, and uneven temperatures.
| If the AC is... | Common result | What you notice |
|---|---|---|
| Too small | Runs long, may not keep up on hottest days | Warm afternoons, constant running |
| Right-sized | Steady run times, good humidity control | Even comfort, fewer swings |
| Too large | Short cycles, weaker dehumidification | Cool but sticky, frequent starts |
How to choose the right size for your York system
For the most accurate sizing, we recommend a Manual J load calculation (it accounts for your home’s real heat gain). If you are matching an existing system, also confirm the outdoor unit tonnage, indoor coil match, and blower/air handler capacity so the system is properly paired.
If you are shopping parts for your York H2RA030S06D central air conditioner or verifying the exact model number on the rating plate, use Sears PartsDirect to search by model and view diagrams and part listings.
Why it matters
Correct sizing protects comfort and efficiency; it also helps prevent compressor stress, coil freeze-ups, and humidity problems that can look like “the AC isn’t working” even when it is running.
