A Split AC is a cooling system made of two units that work together. The indoor unit sits inside your room and blows cool air, while the outdoor unit stays outside and releases the heat. Both units are connected through copper pipes and insulated wiring. This design helps the AC run quietly inside your home while still delivering strong cooling.

Most people prefer Split ACs because they cool faster, make less noise and look cleaner on walls. Inverter models are especially popular since they adjust their speed to match the room’s cooling needs, which can help reduce electricity use over time.
Tonnage is the basic measure of cooling capacity. A small bedroom usually needs around one ton, medium rooms often need one and a half tons and larger rooms may need two tons. The size of the room is the main factor, but things like heavy sunlight, top-floor heat and the number of people in the room can increase the requirement.
Inverter ACs change their compressor speed based on the room’s temperature. This helps maintain even cooling without sudden temperature jumps. Non-inverter ACs work at a fixed speed, which can cool fine but usually uses more electricity than inverter models.
Star ratings give you an idea of how efficiently an AC uses electricity. A higher star rating usually means the AC will use less power for the same amount of cooling. Many buyers choose a five-star inverter AC for long-term savings.
You may come across words like ISEER, BTU and airflow. ISEER shows the efficiency of the AC over a full season. BTU is simply the measure of how much cooling the AC can provide. Airflow, marked in CFM, tells you how much air the AC can move each minute. Higher airflow often means faster and more even cooling.
Split ACs often come with modes that make life easier. Cool mode is the standard setting used on hot days. Dry mode helps lower humidity during sticky weather. Fan mode moves air without cooling it and sleep mode adjusts cooling at night to save electricity while keeping the room comfortable.
When comparing models, it helps to look for copper coils, dust filters, auto-restart options and stabilizer-free operation where available. Some units even offer WiFi control, which lets you operate the AC from your phone.
The indoor unit works best when placed high on a wall where the cool air can travel across the room without hitting obstacles. Corners are not ideal, and walls exposed to heavy sunlight can affect cooling.
The outdoor unit should be installed in a ventilated area where it can release heat easily. It needs a firm, stable base to prevent vibration. Covered boxes or cramped spaces can trap heat and reduce cooling performance.
Most ACs work best when the copper pipe connecting the two units is not unnecessarily long. Extra length can affect cooling and may require adjustments during installation.
Split ACs release water during cooling, so the indoor unit must have a free-flowing drain pipe. If the pipe gets blocked or bent, it can cause water to drip inside the room.
Before installation, it helps to have a proper power outlet ready. The AC should have safe wiring and steady voltage. Many modern ACs claim stabilizer-free operation, but a stabilizer may still be useful in areas with frequent voltage drops.
On installation day, the technician will mount both units, connect them with copper pipes and ensure that air and moisture are removed from the system before starting it. The cooling test is an important part of the process because it confirms that everything is running correctly.
Once installation is complete, observe whether the indoor unit is level and draining water properly. Make sure the outdoor unit is steady and not vibrating too much. It is also useful to check that there are no gaps around the wall opening and that the AC starts cooling without unusual noise.
Most homes feel comfortable at around twenty-four to twenty-six degrees Celsius. Higher temperatures reduce electricity consumption and still keep the room pleasant.
Your remote has several settings that can make cooling better. Swing mode helps spread air around the room. Higher fan speeds cool faster. Sleep mode adjusts cooling gently through the night so you stay comfortable without wasting energy.
Small habits can help the AC work better. Keeping curtains closed during strong sunlight, shutting windows and doors and allowing free airflow around the indoor unit can improve cooling performance.
The filters inside the indoor unit collect dust and need to be cleaned regularly. If they get too dirty, the AC has to work harder, which increases electricity use and reduces cooling.
The outdoor unit also needs space to breathe. Leaves, dust or anything that blocks airflow can affect cooling. Keeping the surrounding area clear helps the unit work smoothly.
A full service once a year is helpful. Technicians check gas pressure, clean the coils, inspect wiring and make sure drainage is smooth. Regular servicing helps maintain performance and extends the life of the AC.
If the AC feels weak, check the filters first. Make sure the room is closed and the temperature is set correctly. Also confirm that the outdoor unit has enough space around it.
Dripping usually happens when the drain pipe is blocked or the indoor unit is not level. Dust on the cooling coils can also cause moisture issues.
Any new or strange noise is worth noting. It may come from loose screws, vibration or something stuck in the fan.
Dust and moisture inside the unit can create smell. Cleaning the filters and keeping the indoor area dry usually fixes this.
Do not keep strong sprays or chemicals close to the indoor or outdoor unit. They can damage parts and create safety risks.
Refrigerant gas handling should be done only by trained technicians. It requires the right tools and safety steps.
Strong voltage swings can affect the system. Turning the AC off during heavy fluctuations helps protect the unit.
If cooling suddenly drops, the outdoor unit stops running, ice forms on the pipes or the AC starts leaking repeatedly, it’s better to call a technician. Electrical problems, refrigerant issues and fan troubles often need professional handling.
Simple cleaning, like washing filters, goes a long way in protecting your AC.
Moderate temperatures and closed rooms help the AC cool faster and use less power.
A yearly checkup supports stable cooling and reduces the chance of unexpected issues during peak summer.
