Your air conditioning system is directly connected to your motor, which means that when you set your climate controls to cold air, you are actually applying some of your horsepower as you cool off, though typically only 5-6 horsepower.

If you estimate its capacity to be similar to the typical window air conditioner in your home, which consumes about 13 to 15 amps at 120 volts, that translates to 1500 to 1800 watts, or roughly 2 horsepower.
What horsepower is in relation to HVAC?
Despite the fact that one horsepower is equal to 0.7457 kW and one kilowatt is equal to 1.337 hp, neither unit is a trustworthy indicator of an air conditioners cooling power because it ignores the effectiveness of the refrigeration system itself.
Is .5 HP aircon enough?
Your aircon's efficiency heavily depends on the space it will cool. Getting a bigger or smaller aircon is not necessarily better.
TIP 1: Match your aircon horsepower (HP) to the size of your room.

Room Size Aircon Horsepower (HP)
6 to 11 sq. m 0.5 HP
12 to 17 sq. m 0.75 HP
18 to 22 sq. m 1.0 HP
23 to 27 sq. m 1.5 HP

19 – 25 sqm. 9,500 – 12,500 1.5 HP
25 – 35 sqm. 12,500 – 17,500 2.0 HP

Why does my car run bad when the AC is on?
The most frequent cause of rough idling while the AC is on is a dirty and/or faulty Idle Air Conditioner (IAC) valve. As strange as it may sound, its not uncommon for a car to idle rough when the air conditioning is on. It could be caused by a dirty throttle body, a bad cooling fan, or a dirty/damaged IAC valve.
Is 1hp aircon enough?
If your house is heavily shaded, you may reduce the capacity by 10%. Normally, 1.0 hp should be adequate for a standard room and 1.5 hp for a standard size living hall for apartments or landed terraced houses.

How much horsepower does a car need?

One of the reasons a car needs enough power is so it can be used in situations other than just cruising; for instance, a typical car needs between 10 and 20 horsepower to maintain a constant speed of 60 mph.12 Sept 2021

What is the importance of HP in aircon?

The higher the listed BTU/hr, the greater the cooling capacity when choosing an air conditioner. Typically, a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity.

Is using the AC bad for your car?

Undoubtedly, both increase fuel consumption; the real question is which increases fuel consumption the most. Open windows increase drag while driving, and running the A/C uses fuel to operate.

Does AC reduce acceleration?

Your ride slows down because your AC causes your RPM to drop, which hurts your acceleration (you want higher revs when you attempt to speed up). If you are cruising at a city pace, you might not notice the difference, but when you slam the accelerator, youre almost certain to feel the loss in strength.

Does running AC affect engine?

Yes, it does. The AC uses the engine to power itself, which adds a burden to the engine and increases fuel consumption. However, at low speeds, it uses less fuel than driving with the windows down.

Why does AC reduce engine power?

Your car loses power when you turn on the AC, and if the issue is severe enough, it may even completely stall. This is because less air is entering the engine, which prevents it from receiving enough oxygen-rich fuel to run smoothly.

How much does AC affect power?

A large window air conditioner uses up to 1,440 watts, a medium one uses 900 watts, and a small model uses about 500 watts per hour. Large, portable AC units can use about 4,100 watts per hour, while mid-sized air conditioners use about 2,900 watts per hour.

Do cars lose power with AC on?

Your car loses power when you turn on the AC, and it might even stall out if the problem gets bad enough. The IAC valve detects this change and responds by altering how much air gets to the engine. Since less air is entering the engine, it isnt getting enough oxygen-rich fuel to run smoothly.
