What Are Split Type Aircon Parts?
Split type aircon parts include every serviceable component of a split HVAC system: the outdoor condenser unit (compressor, condenser coil, fan, and electrical controls) and the indoor evaporator unit (evaporator coil, expansion valve, fan motor, and drain pan). In the Philippines, these parts are critical for maintaining cooling in factories, commercial offices, and high-end residences. Leading OEM brands such as Danfoss (for expansion valves and pressure controls), Copeland (compressors), and Emerson (thermostats and relays) set the reliability standard. 3G Electric has 35+ years of experience sourcing and delivering these industrial components across the archipelago, supporting maintenance teams with genuine parts and technical advice.
How Split Type Air Conditioners Work
A split AC splits the system into two units connected by refrigerant lines. The indoor unit contains the evaporator coil and an expansion device (TEV or capillary tube). The outdoor unit houses the compressor, condenser coil, and fan. The compressor pumps refrigerant (R32 or R410A) to the condenser, where it rejects heat; then the expansion valve drops pressure and temperature, and the evaporator absorbs heat from indoor air. For efficient operation, each part must be matched to the system’s tonnage, refrigerant type, and ambient conditions. Common failure points in the Philippines include compressor burnout (due to voltage fluctuations) and evaporator coil corrosion (due to salty coastal air).
Key Split Type Aircon Parts – Specifications Table
| Part | Typical Spec Range | Common OEM |
|---|---|---|
| Compressor (Rotary / Scroll) | 1–10 HP; 220 VAC 1ph or 3ph; R32/R410A; 850–4000 W cooling | Copeland, Danfoss (Scroll), LG |
| Expansion Valve (TEV) | Orifice 0.5–2.0 mm; connection 1/4″ to 3/8″ OD; MOP 25 bar | Danfoss (T2/TE series) |
| Evaporator Coil | Tube OD 3/8″ or 5/8″; copper/aluminium fins; capacity 800–6000 W | Emerson, Heatcraft |
| Condenser Fan Motor | 1/6–1/2 HP; 220 VAC; 1- or 3-speed; IP44 | GE, Fasco |
| Run Capacitor | 25–70 µF; 440 VAC; operating temp −40 °C to +70 °C | USA Capacitors, AmRad |
Types & Applications in the Philippines
Window-type & split outdoor units: Typical in small shops and apartments. Parts must resist tropical humidity and salt spray. Mini-split (9k–24k BTU/h): Most common for offices and homes; parts like fan motors and capacitor kits are widely stocked. Multi-split and VRF systems: Branch controllers, PCB boards, and inverter compressors are needed; often sourced from original equipment to maintain warranty. Industrial applications (large floor-standing splits) require overcurrent protection and heavy-duty contactors, available through 3G Electric.
Selection Criteria – How to Choose the Right Part
- Match refrigerant and tonnage. Confirm the system’s refrigerant (R22, R32, R410A) and capacity (BTU/hr or HP). Use the manufacturer’s part number whenever possible. Example: a 1.5-ton R410A system needs a TEV rated for 24,000 BTU/h and 38 bar high-side.
- Check voltage and phase. Philippines supply is 220 VAC single-phase (1 ph) for residential and small commercial, or 380 VAC three-phase (3 ph) for larger units. Compressor and fan motor specs must match exactly to prevent burnout.
- Evaluate environmental corrosion. In coastal areas, choose evaporator coils with corrosion-resistant coating (blue fin or gold fin) and copper–aluminum construction. Outdoor fan motors should have sealed bearings and IP44 rating.
- Opt for genuine OEM or approved aftermarket. Generic parts may save cost but often fail prematurely. Danfoss and Copeland parts are recommended for their availability and local support in Metro Manila and Cebu.
- Source from a reliable distributor with technical support. 3G Electric provides pre-sales sizing assistance and can cross-reference obsolete part numbers with current equivalents.
According to Copeland Scroll Compressor Selection Guide, 2021: “For proper compressor performance, the suction gas temperature must not exceed 20 °F above saturated suction temperature, and the electrical supply voltage must be within ±10% of rated nameplate voltage. Installation in coastal environments requires protective treatment on all exposed metallic surfaces to prevent corrosion.”

Frequently Asked Questions
Q: How do I identify the correct compressor for my split AC?
A: Check the compressor model label (usually on the side). Note refrigerant type (R32/R410A), displacement (cc/rev), voltage and phase. For replacement, tell your supplier the original model number; they can cross-reference to a compatible Copeland or Danfoss unit.
Q: Where can I buy split type aircon parts in the Philippines with fast delivery?
A: Contact 3G Electric – we stock or source from leading OEMs (Danfoss, Copeland, Emerson) and ship nationwide. For urgent needs, we prioritize Metro Manila, Cebu, and Davao same- or next-day delivery.
Q: What is the most common failure in split AC evaporator coils in tropical climates?
A: Leaks due to galvanic corrosion between copper tubes and aluminium fins. To extend life, use coils with epoxy coating (gold fin) and ensure proper drainage to avoid standing water.
Q: Can I use a 3-phase compressor on a single-phase supply?
A: No – unless you install a phase converter, which is inefficient and rarely recommended for split AC. Always match the compressor motor to the available supply phase and voltage.
Q: Do expansion valves have a standard size for 1.5 HP splits?
A: Most 1.5 HP split ACs use a TEV with 1/4″ inlet/outlet and 1.0–1.5 mm orifice (rated ~18,000 BTU/h). However, always refer to the original valve’s part number or the system’s design capacity.
Key Takeaways
- Split type aircon parts include compressor, expansion valve, coils, fan motor, and capacitor – each must match original specs for efficiency.
- For Philippine conditions, prioritize corrosion-resistant coils, voltage-tolerant controls, and genuine OEM components.
- Use a districted supplier like 3G Electric who can cross-reference and deliver quickly.
