The summer season has arrived, along with intolerable heat levels that force people to brave outside temperatures. The ACs and coolers will soon be out. The rapid temperature increase leads to an urgent necessity for air conditioning units. There will be heat waves and humid conditions. For that, people in various parts of the country need suitable air conditioning units to stay comfortable. Picking the perfect air conditioner from the wide selection available proves to be a challenging task. The selection consists of three options: powerful split AC models, budget-friendly window models, or flexible portable cooling systems. Here we are with all the necessary information about picking the right air conditioner to assist you during summer’s arrival.
Which AC Should You Choose?

When purchasing an air conditioner, one acquires more than just cooling benefits because it delivers comfort through efficient operation that requires a long-term financial commitment. The type of air conditioning system you choose determines how you will experience its operation, regardless of your room size, financial constraints, or residential instability. We will explain the details of this information step by step.
1. Split AC: The Ideal Choice For Large Rooms And Long-Term Use

The split air conditioner stands out as an excellent choice since it provides powerful cooling ability for big rooms and promises enduring performance. The two components of these AC units operate separately, with one unit installed indoors and the other positioned outdoors. The separate indoor and outdoor units ensure quiet operation and smooth airflow, making them ideal for bedrooms, living rooms, and office environments.
The energy efficiency advantages of split ACs become even stronger with inverter technology as it maintains cooling according to the room temperature. Although this type of air conditioner has a higher upfront cost than standard options, it proves to be more economical gradually because it reduces electricity usage throughout its operational lifespan and offers extended durability.
2. Window AC: Budget-Friendly And Effective Cooling

People who are looking for affordable cooling, a window air conditioning system is a suitable option. These self-contained cooling units require installation in windows or wall openings, thus making it easier to install than split ACs.
Window AC units offer excellent performance in areas between 150 to 450 square feet while requiring straightforward installation. Window ACs become the optimal choice for students and renters because they provide effective cooling at a lower cost than split AC units, although they can be noisier during operation.
Maintenance costs for window ACs are also low because all components reside in one unit; thus, servicing operations become simpler compared to split-system ACs.
3. Portable AC: The Flexible Cooling Solution

A portable AC is the favorable choice for those who relocate frequently since it can be moved between different areas and does not require permanent installation in rented spaces. It also provides a convenient solution for cooling multiple rooms effectively. Customers can use portable ACs as freestanding units, which they can relocate between different rooms. However, portable ACs require proper ventilation, as they contain an exhaust hose that can be directed out of the window or through a pre-cut hole in the exterior wall.
Split AC – Pros And Cons
Pros:
- Quiet operation – Runs much quieter than window or portable ACs, making it ideal for bedrooms and living rooms.
- Doesn’t block windows – Unlike window ACs, it doesn’t take up space or obstruct natural light.
- Better cooling efficiency – Provides powerful and even cooling, making it suitable for larger rooms.
- Energy-saving options – Inverter models can help reduce electricity bills with long-term use.
- Aesthetic appeal – Sleek design blends well with modern interiors.
Cons:
- Complex installation – Requires wall drilling, wiring, and an outdoor unit, making setup time-consuming.
- Higher installation costs – Professional installation is mandatory, and difficult placements (e.g., terrace mounting) add extra expenses.
- Outdoor unit placement affects efficiency – If placed in direct sunlight, it consumes more power and reduces cooling performance.
- Not always cost-effective – Inverter models save energy only with prolonged use; for short-term usage, savings may be minimal.
- Gas leaks can occur – Refrigerant leaks reduce cooling efficiency and refilling costs ₹2,000–₹4,000. Pollution exposure can worsen wear and tear.
- Regular maintenance is needed – Filters should be cleaned every two weeks, and professional servicing is recommended every six months.
- Expensive repairs – Compressor and circuit board failures lead to high servicing costs compared to window ACs.
