Frigidaire FAZ12HS2A12 room air conditioner Parts

Yes. Looking up parts by model number is the most accurate way to get compatible replacement parts for your Frigidaire room air conditioner, especially for a specific unit like model FAZ12HS2A12. Use the exact model number from the unit’s serial plate, then match parts by description and diagram callouts.

For this Frigidaire model, the manual notes the serial plate is located on the outside of the cabinet. Confirm the full model number and serial number before ordering.

• Check the serial plate on the outside of the cabinet
• Write the model number exactly as shown: FAZ12HS2A12
• Record the serial number too (it helps confirm production details)
• Keep your purchase record if you are also checking warranty coverage

Even when you search by model number, the key step is verifying the part by function and location in the unit.

• Start with the model-based parts list and exploded diagrams
• Match the part name to the symptom (cooling, fan noise, water leaks, controls)
• Compare any markings on the old part (labels, connector style, mounting points)
• If your display shows a fault code like HS, AS, or ES, treat it as a sensor-related issue and confirm the correct sensor/thermistor before ordering

Yes. For a 12 x 12 room (144 sq ft), a 1-ton air conditioner is typically more than enough cooling capacity; most rooms that size do best around 5,000 to 8,000 BTU. For your Frigidaire FAZ12HS2A12 room air conditioner, use the sizing and operation guidance in the owner's manual to avoid short-cycling and humidity issues.

A 12 x 12 room usually needs less capacity than 1 ton (12,000 BTU), but real-world conditions can push the need up.

• Typical target for 144 sq ft: 5,000 to 8,000 BTU
• If the room is very sunny or poorly insulated: 8,000 to 10,000 BTU
• If you have multiple people or heat sources (PCs, cooking nearby): add capacity
• If you oversize (like 1 ton in a small room): expect faster cooling but weaker dehumidification
• Best comfort tip: run a steady temperature and keep airflow unobstructed

An oversized window AC can cool the air quickly and shut off before it removes enough moisture. That can leave the room feeling cool but clammy.

• Raise the set temperature 1 to 3 degrees
• Use a lower fan speed for longer run time
• Close blinds/curtains during peak sun (helps the unit run steadier)
• Keep the air filter clean (restricted airflow reduces performance)
• Make sure air can move freely into the room (no blocked louvers)

Proper installation helps both cooling and drainage. The installation instructions for this model call out key setup points.

For step-by-step mounting and tilt guidance, follow the installation guide.

Correct sizing and correct installation work together. When capacity matches the room and the unit is installed with proper airflow and drainage, you get steadier temperatures, better humidity control, and fewer comfort complaints.

On the Frigidaire FAZ12HS2A12 room air conditioner, the main working parts include the front grille and air filter, the evaporator and condenser coils (with sharp metal fins), the fan system that moves air, and the electronic controls (touch pad and remote). For diagrams and locations, use the owner's manual and installation guide.

• Front grille and air filter: the intake area; a dirty filter restricts airflow and can cause poor cooling.
• Evaporator coil (indoor side): absorbs heat from room air; fins can ice up if airflow is restricted.
• Condenser coil (outdoor side): releases heat outside; also has sharp fins.
• Fan and airflow path: moves air across the coils; fan speed affects cooling performance.
• Electronic controls: touch pad, display, and remote functions (mode, temperature, timer, fan settings).
• Power supply cord with TEST/RESET device: safety device that must be able to reset for normal operation.

Knowing the major parts helps you troubleshoot faster. For example, the manual notes that a dirty air filter restricts air and can lead to rapid cycling and reduced cooling, while louvers and blocked front airflow can make the room feel warm even when the unit is running.

• Unplug power before opening panels or cleaning.
• Avoid cuts; coil fins are sharp.
• Do not use an extension cord or adapter plug.
• Keep the outside protective cover in place during operation.

For a Frigidaire room air conditioner like model FAZ12HS2A12, AC spare parts typically range from under $10 for small electrical items to $100 to $700 for common repairs (motors, sensors, control boards), and up to $3,000+ for major sealed-system components such as a compressor or coil.

These are common price bands we see for window and room air conditioner parts (part cost only, not labor):

• Small electrical parts (fuses, capacitors, relays): $5 to $50
• Sensors (thermistors) and switches: $10 to $80
• Fan motor or fan blade: $75 to $250
• Electronic control board or user interface: $120 to $500
• Coils (evaporator or condenser): $200 to $1,200+
• Compressor (sealed system): $400 to $3,000+

Part pricing varies by model, availability, and how complex the component is. For FAZ12HS2A12, these factors usually drive the final total:

• Sealed system vs. non-sealed repair (compressor and coils cost more)
• Labor time (disassembly, refrigerant handling, reassembly)
• Shipping size/weight (motors and coils cost more to ship)
• Whether the issue is maintenance-related (filter cleaning and drainage fixes are low-cost)
• Multiple parts needed (for example, a fan issue can involve a motor, blade, and capacitor)

Use this as a practical rule-of-thumb when you are comparing a repair estimate to replacement.

Room air conditioners are compact; once you get into sealed refrigeration system repairs, the part cost plus specialized labor can approach the cost of a new unit. For many cooling problems, starting with airflow, controls, and installation checks prevents unnecessary parts replacement.

For a 12 x 12 room (144 sq ft), your total cost is the air conditioner price plus any installation supplies or labor. Most homeowners use a 5,000 to 8,000 BTU window unit for this size; confirm your FAZ12HS2A12 features and operation in the FAZ12HS2A12 use and care manual.

These ranges reflect common costs for a small-room window or room air conditioner setup:

• AC unit: $200 to $600 (more with heat, inverter operation, or premium controls)
• Basic install supplies: $0 to $50 (foam seal, side curtains, weatherstripping; often included)
• Optional professional installation: $150 to $400 (varies by window type and access)
• Electrical readiness: $0 to $300+ if a grounded outlet or circuit needs to be added

A 12 x 12 room needs modest capacity; oversizing often causes short run times and weaker humidity removal.

• Typical BTU target: 5,000 to 8,000 BTU
• Bump up capacity for strong sun, poor insulation, or frequent door opening
• Avoid oversizing if humidity control and steady comfort matter most

These items change both price and performance for Frigidaire room air conditioners:

• A grounded outlet located close enough to the cord (avoid extension cords)
• Good sealing around side panels to prevent hot air leaks
• Unblocked airflow at the front grille and outdoor louvers
• Sun exposure (shade reduces run time and electric cost)
• Filter cleaning to keep airflow and efficiency up

Right-sizing and proper setup reduce noise complaints, improve humidity removal, and help prevent water dripping issues that come from poor drainage or restricted airflow.
