Split / Hi Wall Air Conditioning Units

The evaporator coil inside the indoor unit absorbs heat from room air. The cross-flow blower moves air across the coil and spreads it evenly across the room.

The compressor is the heart of the split ac system. It raises refrigerant pressure and temperature so heat can be released outdoors. Inverter compressors vary their speed; fixed-speed compressors switch on and off.

The condenser coil in the outdoor unit releases heat into the atmosphere, helped by a propeller fan. A clean, well-ventilated condenser keeps efficiency high even in peak summer.

The expansion valve or capillary reduces refrigerant pressure before it enters the evaporator, making it cold enough to absorb heat from the room.

The split AC air filter traps dust, pet hair and larger particles. Many models add PM 2.5, anti-bacterial or catechin filters for cleaner indoor air.

The printed circuit board (PCB) controls the compressor, fans, sensors and display. It also runs protection logic and shows error codes when a fault occurs.

An inverter split AC adjusts compressor speed to match the room's cooling need. It cools fast, then runs at low speed to hold the temperature steady, which cuts power use, noise and wear. An inverter split AC for home is the preferred choice for bedrooms and living rooms used for long hours.

A fixed-speed split AC runs its compressor at full speed and switches it off once the set temperature is reached. It costs less upfront and suits rooms used for short periods, but it draws more power and causes wider temperature swings.

A hot and cold split AC, also called a split AC with heating or heat pump split AC, reverses the refrigerant cycle to warm the room in winter. This heat pump air conditioner is ideal for hill stations, north India and any space that needs year-round comfort from one unit.

A multi split AC connects two to five indoor units to a single outdoor unit. It saves balcony and facade space in apartments and offices where several rooms need cooling but outdoor space is limited.

For most Indian homes and offices, the inverter AC vs non inverter AC decision favours inverter models, as the lower electricity bills recover the price difference within a few summers.

• 1 Ton Split AC: Suits small bedrooms, study rooms and cabins of up to about 120 sq ft.
• 1.5 Ton Split AC: The most popular size in India, ideal for master bedrooms, living rooms and a split AC for small office use of 120–180 sq ft.
• 2 Ton Split AC: Best for large living rooms, conference rooms and shops of 180–250 sq ft.

For larger halls, 2.5 ton wall mounted units, a 3 ton ac system or ceiling mounted ac unit options such as cassette ACs are more suitable. Very large spaces needing a 4 ton ac system or 5 ton ac system are usually better served by ducted or VRF solutions.

This chart assumes a standard 9–10 ft ceiling and normal heat load. Our team confirms the final split AC sizing for your room after a site survey.

• Sunlight: West-facing rooms and large glass windows add heat; add roughly 10–20% capacity.
• Occupancy: Each extra person adds heat; offices and shops with more people need higher capacity.
• Floor level: Top-floor rooms under a roof slab absorb far more heat than middle floors.
• Appliances: Computers, TVs, kitchen equipment and lighting all increase the load.
• Ceiling height and insulation: Higher ceilings and poor insulation need extra cooling.

The Bureau of Energy Efficiency (BEE) rates every AC sold in India from 1 to 5 stars. More stars mean lower power consumption for the same cooling. The label also shows the ISEER value and estimated annual units consumed, making it easy to compare models.

ISEER (Indian Seasonal Energy Efficiency Ratio) measures how much cooling an AC delivers per unit of electricity across a typical Indian year, factoring in varying outdoor temperatures. A high ISEER air conditioner cools more for every unit you pay for. Inverter 5 star models generally offer the highest ISEER values.

If the AC runs through the night or all day in an office, a 5 star split AC is usually the smarter long-term investment.

A fixed-speed compressor repeatedly starts at full power, which wastes energy. An inverter compressor avoids these power spikes by running continuously at the speed the room needs. The result is lower split AC power consumption, stable cooling and a longer compressor life.

R32 is now the most widely used refrigerant in new ACs in India. An R32 split AC offers high cooling efficiency, needs a smaller refrigerant charge and has a much lower global warming potential than R410A.

R410A is an ozone-safe refrigerant used in many inverter ACs and commercial systems. It performs well but has a high global warming potential, so manufacturers are gradually moving to R32 and R290.

R290 (propane) is a natural refrigerant with near-zero environmental impact and excellent efficiency. It is used in select energy-efficient models and requires trained technicians for safe handling.

R22 damages the ozone layer and is no longer used in new ACs in India. Older R22 units can still be serviced, but gas is becoming costlier and harder to source. If your AC is over 8–10 years old and uses R22, upgrading to an inverter R32 model will cut bills significantly.

Copper coils transfer heat well, resist corrosion better and are easier to repair, which makes them ideal for coastal cities like Mumbai. Aluminium coils cost less but are harder to repair once damaged. Look for anti-corrosion coatings on either type.

A smart split AC or WiFi split AC lets you control temperature, schedules and modes from your phone, track energy use and pre-cool a room before arriving. Many models also work with voice assistants.

A split AC with air purifier filters captures fine PM 2.5 particles, dust and allergens, while anti-bacterial filters limit germ growth. This is valuable in polluted cities and for homes with children or elderly members.

Auto-clean dries the indoor coil after use to prevent mould and odour. Self-diagnosis displays error codes so technicians can identify faults quickly.

Dry mode removes excess moisture during humid monsoon days without over-cooling the room, which is especially useful in Mumbai, Thane and other coastal areas.

Convertible inverter ACs let you run at 40%, 60%, 80% or 100% capacity. Lower modes save power when fewer people are in the room or when the weather is mild.

A low noise split AC runs as quietly as 19–25 dB in silent mode, which is ideal for a split AC for bedroom use, libraries and clinics.

A single hi wall unit throws air mainly in one direction, so large halls or long open offices may have uneven cooling. Cassette, ducted or VRF systems work better there.

The outdoor unit needs a ventilated balcony, ledge, terrace or wall bracket. In some housing societies, facade rules also affect placement.

Each model has a maximum pipe length and height difference between units. Exceeding these reduces cooling and may need extra gas charging.

Split ACs recirculate room air and do not bring in fresh outdoor air. Rooms with many occupants may need separate ventilation or a fresh air unit.

Mount the indoor unit on a strong wall, about 7–8 ft high, with at least 15 cm clearance at the top. Airflow should spread across the room without blowing directly on beds or desks, and the unit should be away from heat sources and direct sunlight.

Place the outdoor unit in a shaded, well-ventilated spot with enough space around it for hot air to escape. Use a rust-proof wall bracket or floor stand, with anti-vibration pads to reduce noise. Keep it reachable for future service.

Keep the copper pipe run as short as practical, ideally 3–5 metres, and within the manufacturer's limit. Both lines must be fully insulated, with the correct diameter for the model. Joints are flared or brazed and leak tested.

The drain pipe needs a continuous downward slope, with no loops or dips, and should end in a proper drain point. This prevents water dripping from the indoor unit or on your walls.

Use a dedicated MCB and correctly rated copper wiring. Most inverter ACs handle a wide voltage range, but a stabilizer is recommended for non-inverter models and areas with frequent fluctuation.

Before opening the refrigerant valves, the piping is vacuumed with a vacuum pump to remove air and moisture. If the pipe length exceeds the pre-charged limit, extra gas is added by weight. Skipping vacuuming is a common cause of poor cooling and compressor failure.

Ask us for a transparent split air conditioner installation cost for your site before work begins.

Clean the split AC air filter every 2–3 weeks in peak summer and at least monthly otherwise. Dusty filters reduce airflow, cooling and efficiency.

A wet service uses a jet pump to wash the indoor coil, blower and drain tray, and the outdoor condenser. We recommend it before summer and after the monsoon, or 2–3 times a year for heavy use.

A properly sealed AC should not need frequent gas refilling. If cooling drops, our technicians first locate and repair the leak with pressure testing, then vacuum and recharge the correct refrigerant to specification.

Our AMC plans cover single homes as well as offices and multi-unit commercial sites.

Premium brands and models with advanced purification or heating cost more. For a split air conditioner 1 ton, the 1 tonne ac price is lowest; the ac price 1.5 ton split sits in the middle and is the most requested.
