AC typically uses 1 to 4hp depending on outside temp. but for a small car, say 2hp. That’s 10% of the power used to run the car. So your fuel economy will worsen by 10%.
How much HP does it take to run an AC compressor?
Air compressors typically have a horsepower rating between 1.5 and 6.5, though some larger, stationary air compressors can have up to 15 HP. If you are using standard electric power outlets, you’ll need an air compressor at 2 HP or less because standard AC cords require lower voltage to function.
How do I choose the right horsepower for my air conditioner?
1) Horsepower – How much is needed? The basic rule of thumb is the bigger the room is, the higher the cooling capacity is required. Another factor to consider is the amount of heat exposure the room has during the day. If the room has direct sunlight, it might need bigger HP to bring the temperature down.
How much does AC reduce horsepower?
Furthermore, air conditioners only use about 10–15 HP. If you are cruising on the highway, you engine power used will be greatly reduced by straight, level steady speeds and be in the 20–30 HP range. One may also ask, how much engine power does AC use?

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 |
How can I tell the horsepower of my air conditioner?
How to Calculate HP for an Air Conditioning Unit
- Multiply the air conditioner’s size in tons by 12,000 to convert its cooling capacity to British Thermal Units per hour.
- Divide this answer by 3.412 to convert it to watts: 18,000 / 3.412 = 5,275 watts.
Does air conditioning affect acceleration?
Starting with the age-old question: YES, running your air conditioning will slow down your Volkswagen vehicle’s acceleration. Also, 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).
Does air conditioning reduce engine power?
You’ve likely noticed your car’s engine RPMs increasing at idle when the compressor kicks on. It does this to offset the power drawn by the air conditioning system. You’ll also find that the power drawn from the engine has a more noticeable impact with smaller engines.
How much HP does a power steering pump use?
During recent tests with several GM-style power steering pumps modified for competition, the tester demonstrated they absorb around 3.6 hp at 8,000 rpm. By comparison, KRC’s Pro Series 5.9 cc pump used on Aston Martin’s victorious Le Mans sports cars absorbs 1.9 hp.
How many horsepower does an air con unit have?
Floor Area (in square meters) / AC Unit Size (Horsepower) 10.5sqm: 0.5 hp 11 to 14sqm: 0.75 hp 15 to 21sqm: 1.0 hp
How to calculate your air conditioner horsepower based on your floor area?
Recommended Videos. 1. Horsepower. Assess the air conditioner horsepower you need based on your room’s floor area. Or when in doubt, consult your air conditioner dealer. Here’s a quick guide: Floor Area (in square meters) / AC Unit Size (Horsepower) 10.5sqm: 0.5 hp. 11 to 14sqm: 0.75 hp.
How much power does the AC draw from the engine?
It does this to offset the power drawn by the air conditioning system. As to the question of how much power it draws, there’s no one answer, as it depends on the make and model, the engine, the condition of the engine and the air conditioning system and much more.
How much power does an average air conditioner use?
Air conditioner power consumption trumps that of most appliances. The power consumption of air conditioners averages 318 watts (for a 24,000 BTU unit) in most American households. That 318-watt average (source: U.S. DOE) adds up to 228 kWh per month.
