It’s an important investment today. It will play a key role in your home energy expenses for years to return . And when the summer heat is at its worst, you will want your family to have the best, most reliable cooling comfort possible. Here are a few things to consider for you.

How can I be sure my Unit is the right capacity?

Air Conditioner Cooling Capacity Chart
Area Capacity in BTU’s per hour Tonnage of the AC

0 to 90 sq. ft. ~5,000 BTU= 1 ton
90 to 110 sq. ft. ~12,000 BTU= 1.2 ton
120 to 150 sq. ft. ~18,000BTU= 1.5 ton
150 to 200 sq. ft. ~24,000BTU= 2 ton

Obviously, an air conditioning that’s too small won’t keep your home sufficiently cool. But what many don’t realize is that an oversized system will cycle (turn on and off) quite require, wasting expensive energy and possibly putting undue strain on the compressor.

the optimum size for your home by making a careful study of your cooling capacity requirements in your rooms. Window dimensions and exposure, Floor space, insulation. Heat-generating appliances. The direction your home faces. Even the quantity of your home’s exterior shaded by trees.

specify the cooling capacity of the system in either Btu/h (British thermal units of heat removed per hour) or refrigeration tons (one ton being equal to 12,000 Btu/h,3000kgcl/h,3.5kw.

Which air conditioners are more energy efficient?

To help you purchase more energy-efficient air conditioning , Bureau of Energy Efficiency in 2016 came up with a replacement rating methodology, ISEER (Indian Seasonal Energy Efficiency Ratio) Ratings, which are better and stringent. Higher the star ratings of an Air Conditioner, lesser the power it consumes. This, however, does not mean that you should always go for a 5-star rated AC, say experts.

The decision should mainly be supported your usage pattern. “If you are going to run the Air Conditioner few hours daily, then a 3-star rated A/C is good enough,” Also, lower star-rated A/Cs usually have higher air circulation rate, so your room cools faster. A/c Experts suggest that only if you’re A/C usage is over eight hours do you need the costlier but less power consuming 5-star rated A/C, to make a worthwhile difference to your electricity bill.

After-sales service Much like cars, A/Cs need regular servicing for optimum a/c performance. So, one of the things you need to keep in mind before buying an Air Conditioner is the company’s aftersales service, and warranty. A little research will throw up names of the best and the worst service providers.

Much like automobile manufacturers, today’s air conditioning manufacturers are required by law to guage and rate their equipment consistent with its saving energy efficiency. This rating is understood within the industry as a SEER, or Seasonal Energy Efficiency Rating. The higher the SEER, the more efficient the unit.

Most new homes with central air come equipped with a typical builder. However, when replacement becomes necessary, property owners can upgrade their air conditioning by specifying a more energy-efficient units.

High SEER models are generally costlier , but can easily structure the difference by reducing your home energy bills over the end of the day .

Are some air conditioners built better than others air conditioners?

The compressor is the heart of a condensing unit. On a summer day, it works long and full load capacity. the highly advanced scroll compressor in every condensing unit. Scroll Compressors are recognized by the industry as the leader in reliability, efficiency and quiet operation for Air Conditioner.

Other features to look for include louvered steel cabinets that protect the coils from damage and expensive repair cost.
Also, with some condensing units have a grill design that minimizes air restriction for quieter fan operation.

Other important features of air conditioners to consider

Anti-bacteria filter.

Removes bacteria, pollen, dust mites, and allergens from the air to create a healthy environment.

Dust filter.

Dust filter Catches minute dust particles and dust mites.


Helps remove excess moisture from the air during the rains, prevents the space from becoming damp, and inhibits growth of fungus and bacteria.


Raises the temperature to comfortable levels during winters and eliminates the necessity to get a separate heater unit.

Auto cleaning.

Automatically removes the mould and bacteria deposits inside the ac blower.
