Difference between Inverter AC and Regular AC

How to determine the cooling capacity

The AC capacity is the next crucial factor to consider. You need to calculate the square foot area of your room to understand the capacity needed to cool it. Read this AC purchase guide to know more.

Room size

The capacity required to cool a room depends on the size of that room. For instance, a 1-ton AC is more than enough for a small room of 150 sq.ft., the heat load is manageable. However, in a medium-sized room, a 1-ton AC is likely to be overloaded.

Noise level

If you’re a light sleeper or have an infant in the room, a loud AC can be a disturbance. So, remember to check the noise level, especially for window ACs. However, it may be best for you to buy a split AC in this case.

Average city temperature/weather

The ambient temperature is also critical in determining the AC type you need. If you live in an area with harsh summers, you may require a 1.5- or 2-ton AC even for medium-sized rooms.

Number of occupants

Another essential tip for buying an air conditioner is to consider the number of people in a room as this adds to the heat load of the room. A crowded room requires a stronger unit.

Smart home compatibility

Smart features in your AC can help you seamlessly integrate it with other smart devices in your home.

Aluminium coil vs copper coil

Coils become the next key deciding factor as they determine the overall efficiency of your AC. Continue reading this air conditioner buying guide to understand what sets the two coils apart.

Power consumption (BEE rating)

An important part of the air conditioner buying guide is to help you understand the power consumption of your AC. The BEE Rating, now called ISEER rating, is issued keeping in mind an ACs Energy-Efficiency Ratio (EER). Air conditioners are rated in British Thermal Units (BTUs), regardless of their tonnage and capacity.

Features to look for when you’re buying an AC

Wi-Fi compatibility

Self-clean feature

Automatically moves a brush across the filter to clean dirt on the wings

Activity sensors

Monitors activity to reduce energy consumption if you’re not in the room

Voice-command compatibility

Allows you to control your AC hands-free

App control

How to ensure optimal cooling

Keep the following tips in mind to get the most from your AC purchase:

Turn off extra heat sources

Lights, appliances add heat to the room

Ensure airflow for the AC

Keep the AC vents clear of obstacles like curtains

Check for air leaks

These can be around doors, vents and windows

Block direct sunlight

Sunlight adds heat to the room and makes it harder to cool

Use the ‘Eco’ mode

This controls temperature efficiently and limits power consumption

Pay attention to after-sales service and additional warranty

Once you’ve identified an AC, ensure that it comes with good after-sales service. If you can, do opt for an additional warranty. Read on to know how these 2 factors can help you.

  • They protect you from paying for breakdowns due to defects
  • They give you access to professional technicians familiar with the AC
  • They help you lower additional costs/expenses
