How Do I Choose The Right Horsepower For My Air Conditioner?

Normally, 1.0hp should be sufficient for a standard room and 1.5hp for a standard size living hall for apartments or landed terraced houses. If your house is heavily shaded, you may reduce the capacity by 10%. If your house is west-facing and receiving full afternoon sun, increase the capacity by 10%.

How much hp do I need for my aircon?

How to Calculate HP for an Air Conditioning Unit

1. Multiply the air conditioner’s size in tons by 12,000 to convert its cooling capacity to British Thermal Units per hour.
2. Divide this answer by 3.412 to convert it to watts: 18,000 / 3.412 = 5,275 watts.

What is the difference between 1hp and 1.5 hp air conditioner?

The hp rating of an air conditioning system is all about the power of the motor (compressor) inside the AC. The more powerful the motor of an air conditioner the greater its capacity to cool (or remove heat from) a given space.

How powerful should my AC unit be?

One ton is equal to 12,000 BTUs. The smallest standard size is 1.5 tons, which is 18,000 BTUs and the largest is 5.0 tons, which is 60,000 BTUs. To calculate for yourself how big of a central air conditioning unit you need, multiply your home’s total square footage by 20. Divide that total by 12,000.

Does horsepower matter in aircon?

Definitely! For a house that is empty during the day, it is OK to splurge a little bit by investing on an AC unit with bigger horsepower (HP). It is because a 2HP AC would need lesser time to cool a room as compared to a 1.5HP AC would for a room of the same size.

Is my AC powerful enough?

You need approximately 6,000 BTUs to cool an area under 300 square feet, 10,000 BTUs for 301 to 549 sqft., 16,000 BTUs for 550 to 999 sqft., 22,000 BTUs for 1,000 to 1,199 sqft., 30,000 BTUs for 1,500 to 1,999 sqft. and 34,000 BTUs for 2000 to 2,499 square feet.

Is it okay to use high HP aircon in small room?

Myth #2 – Bigger AC units are better
For small rooms up to 13 sqms with 1-2 occupants, it’s ideal to use aircons below 1.0HP. On the other hand, for medium rooms up to 23 sqms with 3-5 occupants, it’s recommended to have 1.0-1.5HP AC. While a large room up to 41 sqms needs 2.0HP or higher to achieve proper cooling.

Does higher horsepower consume more electricity?

While AC sellers usually cite the horsepower, this really only refers to the power input (1 horsepower = 745 watts). The higher horsepower means that it consumes more electricity.

Is it better to have one big AC or two small ones?

And if you want to cool a large, open L- or T-shaped space, you’re better off with two smaller units rather than one large one. “The goal is to keep the cold air from pooling on the floor,” explains Hank Rutkowski, director of technical affairs for the Washington, D.C.-based Air Conditioning Contractors of America.

How much electricity does a 1.5 hp air conditioner use?

What is the 3 most important factors for an AC unit?

The Big Three
You want to look at the AC unit’s power, energy efficiency, and noise. There are many kinds of air conditioning units that can fulfill your cooling needs, but you should be able to narrow down the ones which can work the best for you.

What happens if you oversize an air conditioner?

Too Hot or Too Cold Air
An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. First, your home won’t benefit from gradual, even heating and cooling. As a result, you could end up with a number of hot or cold spots throughout your home.

What happens if your AC is too big?

If your air conditioner is too big, you’ll have hot spots – or inconsistent cooling – throughout your home. Hot spots occur most often when cold air doesn’t disperse through the home efficiently enough. You’ll notice that some of your rooms are cool and comfortable, while others are hot and humid.

Is a bigger AC more efficient?

An “oversized” air conditioner will cool your house quicker, but it will use more electricity and will not remove humidity adequately. Contrary to popular belief – and intuition – long AC system run cycles are far more desirable and energy efficient than short-run cycles.

Does an AC use a lot of electricity?

While air conditioners are fairly energy-intensive, their exact energy usage depends on several factors. Generally speaking, however, you can expect a central air conditioner to use between 3000 and 3500 watts per hour.

How much HP do you get from cold air?

5-20 horsepower
Cold Air Intakes are said to improve your vehicle’s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn’t enough power to put you back in your seat, it will give your car or truck a little pep in its step.

What happens if BTU is too high?

If your air conditioner has a bigger BTU rating than the room size needs, it will cycle off too quickly, waste energy, and will not adequately dehumidify the space. So a higher BTU than needed is definitely not recommended.

What size AC do I need for 2000 square feet?

If your home is 2000 square feet, you can calculate your HVAC needs the same as you would for a 1600 square foot home. Assuming one ton of cooling capacity can cool 400 square feet of your home, you’ll need about 5.0 tons of air conditioning capacity. Multiply this by 12,000 BTUs, and you’ll get 60,000 BTUs.

Will an air conditioner with a higher BTU cool my room faster?

If you purchase an air conditioner with a higher BTU than needed, you will waste a lot of excess energy and the air conditioner will cycle off too quickly. Thus, an air conditioner with a higher BTU will not cool a room faster.

Is it better to leave rooms open or closed for AC?

In general, it’s best to keep your interior doors open as often as possible in order to allow air to flow freely from room to room. This will avoid pressure problems in your home and will make it easier for your air conditioner to cool your home evenly and with less energy.

How do I choose an air conditioner for my small room?

Small Rooms
If your room is 20 square meters or smaller, we recommend small-capacity air conditioners with a cooling capacity between 2kW and 3.5kW. If your room is 20 square meters or smaller, we recommend small-capacity air conditioners with a cooling capacity between 2kW and 3.5kW.
