Comprehensive definitions of air conditioning terms used in the Philippines. From basic concepts to specialized commercial systems.
The standard measurement of cooling capacity. One BTU is the energy needed to raise one pound of water by 1°F. A 1.0 HP aircon produces approximately 9,000 BTU/h of cooling.
Aircon capacity rating used in the Philippines. 1 HP ≈ 9,000 BTU/h. Common residential sizes: 0.75 HP (small bedroom), 1.0 HP (master bedroom), 1.5 HP (living room), 2.0 HP (large spaces).
Cooling output (BTU/h) divided by power input (Watts). Higher EER = lower electricity cost. Philippine 5-star rating requires EER of 12.0+. Top brands like Daikin achieve 14.0–15.5.
Average efficiency measured across an entire cooling season rather than a single test point. Accounts for varying temperatures and part-load conditions. More accurate than EER for real-world savings.
Ratio of cooling output to energy input, measured in watts. COP of 3.0 means 3 watts of cooling per 1 watt of electricity consumed. Used internationally alongside EER.
The total amount of heat that must be removed from a space to maintain the desired temperature. Calculated using room size, insulation, occupancy, equipment, and solar heat gain.
A unit of cooling capacity equal to 12,000 BTU/h. Commonly used for commercial HVAC sizing. A typical 1.0 HP residential unit is approximately 0.75 TR.
Measures airflow volume — how much air the unit moves per minute. Higher CFM means faster air distribution across the room. Important for large open-plan spaces.
Superheat is the temperature of refrigerant gas above its boiling point; subcooling is the temperature of liquid refrigerant below its condensing point. Technicians use these to verify correct refrigerant charge.
Two-piece system with an indoor wall-mounted evaporator and outdoor compressor connected by copper piping. Most popular type in Philippine homes. Quiet operation, flexible placement.
Self-contained single unit installed through a wall or window opening. More affordable than split type but louder. Common in Philippine apartments and budget installations.
Ceiling-recessed commercial unit that distributes air in 2 or 4 directions through a decorative panel. Used in offices, restaurants, and retail spaces. Requires false ceiling.
Tall vertical unit placed on the floor, resembling a tower. High cooling capacity (3–5 HP) for large spaces. Common in Philippine function halls, churches, and open offices.
Unit mounted on the ceiling without recessing. Ideal for commercial spaces without false ceilings. Provides wide airflow coverage for warehouses and workshops.
Specialized cooling system designed for data centers, server rooms, and telecom facilities. Maintains exact temperature (±0.5°C) and humidity (±2% RH) for sensitive electronic equipment. Mr. Aircon carries AR precision units for mission-critical environments.
One outdoor unit connected to multiple indoor units (2–5). Each indoor unit can be controlled independently. Ideal for homes or offices needing cooling in several rooms with limited outdoor space.
Variable Refrigerant Flow — large-scale commercial system connecting one outdoor unit to 20–60+ indoor units. Daikin invented VRV technology. Used in Philippine malls, hotels, and high-rise buildings.
Movable unit on wheels with an exhaust hose vented through a window. No permanent installation needed. Lower efficiency than split or window types but useful for temporary cooling.
Variable-speed compressor that adjusts power based on cooling demand instead of cycling on/off. Saves 30–50% on electricity, runs quieter, and maintains more stable room temperature. Standard on premium units.
Traditional compressor that runs at one speed — full power on, then completely off. Cheaper upfront but uses more electricity through constant start-stop cycling. Still common in budget window types.
LG’s twin-rotary compressor technology that reduces vibration, noise, and energy use. The dual mechanism provides smoother operation and greater durability than single-rotary inverter compressors.
Eco-friendly refrigerant with 67% lower global warming potential than R410A. Provides approximately 10% better energy efficiency. Now standard on most new inverter units sold in the Philippines.
Previous-generation refrigerant that replaced ozone-depleting R22. Non-toxic and non-flammable. Still used in many existing units but being phased out in favor of R32 for environmental reasons.
Older refrigerant being phased out globally due to ozone depletion. Still found in aircon units manufactured before 2015. Recharging R22 is increasingly expensive as supply dwindles.
Built-in wireless connectivity allowing control via smartphone app. Set schedules, adjust temperature remotely, and monitor energy consumption. Available on Samsung (SmartThings), LG (ThinQ), Daikin (D-Mobile).
Air purification technology using hydroxyl radicals to inhibit bacteria, viruses, mold, allergens, and odors. Generates nano-sized water particles that penetrate fabric and surfaces.
Technology delivering gentle, draft-free cooling through 23,000 micro-holes once the set temperature is reached. Prevents the uncomfortable cold blast feeling while maintaining efficiency.
High-speed cooling mode that runs the compressor and fan at maximum output for rapid temperature drop. Useful when entering a hot room. Available on most inverter models from all brands.
Gradually raises the set temperature by 1–2°C during sleep hours to save energy without noticeable comfort change. Most units also have programmable on/off timers.
Feature that automatically dries the evaporator coil after operation to prevent mold and bacteria growth. Reduces cleaning frequency. Available on Samsung, Panasonic, and Daikin models.
The heart of an aircon system — a motor-driven pump that circulates refrigerant through the cooling cycle. Most expensive component to replace (₱8,000–₱25,000). Warranty ranges from 5 years (Carrier) to 12 years (Panasonic).
The indoor coil (heat exchanger) where liquid refrigerant absorbs heat from room air and evaporates into gas. Must be professionally cleaned every 3–4 months to prevent efficiency loss and mold growth.
The outdoor coil where hot refrigerant gas releases absorbed heat to the outside air and condenses back to liquid. Keep clear of walls, plants, and obstructions for proper heat dissipation.
The electronic control board that manages temperature sensing, compressor speed, fan control, and error diagnostics. Sensitive to power surges; use an AVR for protection.
The indoor fan that draws room air across the evaporator coil and distributes cooled air. A failing blower produces weak airflow, unusual noises, or vibration. Replacement costs ₱2,500–₱5,000.
Insulated copper tubes connecting indoor and outdoor units, carrying refrigerant in both liquid and gas phases. Standard installation includes up to 10 feet. Additional piping costs ₱350–₱500 per foot.
Collects condensation from the evaporator coil and routes it outside. Clogged drain lines are the #1 cause of water leaking from indoor units in Philippine homes. Clean every 3 months.
Mesh screen that traps dust, pollen, and particles before air passes over the evaporator coil. Should be cleaned every 2–3 weeks during heavy use (March–June in the Philippines).
Controls the flow of liquid refrigerant into the evaporator coil, reducing its pressure and temperature before it absorbs room heat. A malfunctioning valve causes poor cooling or ice buildup.
Electrical component that stores and releases energy to start the compressor and fan motors. A common failure point in older units — symptoms include the unit not turning on or humming without starting.
Electronic sensor that measures room and coil temperatures, sending data to the PCB to regulate compressor speed and fan output. Faulty sensors cause inaccurate temperature readings.
Adjustable horizontal and vertical flaps that direct airflow direction. Motorized louvers automatically sweep for even air distribution. Manual override is available on most remote controls.
AR brand precision cooling units designed for data centers, server rooms, and telecom facilities in the Philippines. Features ±0.5°C temperature control, humidity regulation, and 24/7 operation capability. Mr. Aircon is an authorized AR precision aircon dealer.

Data center airflow management strategy that separates hot exhaust air from cold supply air using physical barriers. Increases precision aircon efficiency by 20–40%.
Precision aircon systems with built-in compatibility for uninterruptible power supply integration, ensuring cooling continues during power outages in mission-critical server rooms.
Scheduled regular servicing to maintain aircon efficiency and extend lifespan. Typically quarterly for residential and monthly for commercial. Mr. Aircon’s PMP starts at ₱1,200 per visit.
Professional disassembly and thorough cleaning of evaporator coil, blower fan, drain pan, and filters using specialized coil cleaner. Recommended every 3–4 months in the Philippines. Takes 45–60 minutes per unit.
Intensive cleaning using chemical solutions to dissolve stubborn buildup on evaporator and condenser coils. Required when standard deep cleaning cannot restore cooling performance or eliminate odors.
Adding refrigerant gas (R32 or R410A) to restore the system’s cooling capacity. Low refrigerant indicates a leak that must be located and repaired first. Mr. Aircon charges from ₱3,800.
Essential step during installation where a vacuum pump removes air and moisture from the copper piping before releasing refrigerant. Skipping this step causes contamination and premature compressor failure.
Process of locating refrigerant leaks using electronic leak detectors, UV dye, or nitrogen pressure testing. Common leak points: flare connections, copper piping joints, and evaporator/condenser coils.
Major repair involving disassembly, inspection, and replacement of worn internal components (valves, bearings, gaskets) in the compressor. An alternative to full compressor replacement at lower cost.
Pre-installation assessment where a technician measures room dimensions, checks wall type, evaluates electrical capacity, and determines optimal unit placement. Mr. Aircon provides free site surveys in Metro Manila and Cebu.
Device that stabilizes voltage supply to the aircon, protecting the sensitive inverter board from power fluctuations common in Philippine electrical grids. Strongly recommended for inverter units.
Setup where the indoor and outdoor units are mounted on opposite sides of the same wall. Minimizes copper piping length and cost. The simplest and most affordable installation type.
Routing copper pipes from the indoor unit sideways along the wall to reach the outdoor unit positioned around a corner or on a different wall. Requires additional piping and concealment work.
PVC or metal cover used to conceal exposed copper pipes and drainage lines along walls and ceilings. Provides a clean appearance. Standard trunking costs ₱300–₱500 per meter.
The brass fitting where copper tubing connects to the indoor and outdoor units. Must be properly tightened to prevent refrigerant leaks. The most common source of installation-related leaks.
Small electric pump installed when the indoor unit is positioned below the available drain line exit point. Pumps condensation upward against gravity. Adds ₱2,500–₱4,000 to installation cost.
A separate electrical circuit with its own circuit breaker in the panel box, reserved exclusively for the aircon. Required for all split-type and high-HP units. Prevents overloading and tripping.
Metal support structure for the indoor wall unit (mounting plate) or outdoor unit (L-bracket or floor stand). Must be securely anchored to withstand the unit’s weight and vibration.
The pair of insulated copper tubes (liquid line and suction line) connecting the indoor and outdoor units. Carries refrigerant in both directions. Must be properly insulated to prevent condensation.
Creating a circular hole through concrete walls for routing copper piping between indoor and outdoor units. Requires a specialized drill with diamond-tipped core bits. Costs ₱800–₱1,500 per hole.
