How Much Does An Air Conditioner Weigh? (All Types)

Learn how much an air conditioner weighs so you can safely install or move it in the home.

by Josh M

Have you ever found yourself wondering, “How much does an AC unit weigh?” We have compiled an extensive list of air conditioner units by type and weight. The weight of an AC machine can affect where you place the home appliance, so it’s wise to know how much various air conditioning units weigh. Read on to discover how much AC units weigh.

Central Air Conditioners

Central Air conditioning systems are the types of internal systems that move throughout your entire home or business through supply ducts and open registers (those panels in the wall, ceiling, or floor).

Central air conditioners use outside air to cool the home through the intake/outtake process. They also tend to share ductwork with your home heating system. The mechanism that forces the cool air in and out of the internal vents typically weighs between 70 and 85 pounds. Central air conditioners generally have an outdoor component and an indoor component.

Window Air Conditioners

Window air conditioner units are the units you affix outside of your home or business to the window, and they work only to cool the room in which they are placed. These units will be partially in the house and partially outside of the home while being tethered to the window.

Window air conditioning units tend to weigh between 45 and 130 lbs. These units cannot weigh too much, or the window would be unable to fully support them, so they are created at lower weights.

Ductless Mini-Split Air Conditioners

A ductless mini-split air conditioning unit is one that doesn’t require air ducts. This can be convenient for older homes where air ducts might not reach certain rooms or in the case of a home addition in which you do not want to extend the ductwork.

The mini-split unit can provide AC to a particular area and has its own fan as well as its own evaporator coil. These units have both outdoor and indoor pieces. They weigh between 75 and 275 pounds, on average.

Portable Air Conditioners

A portable air conditioning unit is convenient because it can be moved frequently and switched from room to room. It also is easy to move when your lease is up and you change apartments.

A portable AC unit typically has wheels so it can be moved quickly, and therefore these units aren’t always as lightweight as consumers think they will be. These units tend to weigh between 50 and 100 pounds. Even with wheels, you may need another person to help move the unit, particularly if you are wheeling the AC unit across the carpet.

RV Air Conditioners

RV air conditioner units are designed to be lightweight to help with gas consumption but also need to be robust enough to cool down the entire trailer.

Many people who use RVs use them in hot weather conditions and need a reliable RV AC machine. These units can weigh between 80 to 250 lbs. There are many different types of RV air conditioners, and the specific model used depends on the type of RV.

Air Conditioners By Ton (1.5, 2, 2.5, 3, 3.5, 4, 5)

AC units can also talk about how much heat can be removed with tonnage instead of BTU. Tonnage is how much heat is being removed within a single hour. For example, 1 ton AC unit typically weighs between 75 and 100 pounds and can remove 12,000 BTU.

The higher the tonnage on an AC unit, the more effective that unit is at cooling down the air and creating a comfortable space. Typically, we recommend determining the square feet of the space you want to be cooled and then multiplying that number by 25.

Air Conditioners By BTU (5000, 6000, 8000, 10000, 12000, 14000, 18000, 25000)

Air conditioner units by BTU weigh more based on the amount of BTU (British Thermal Units) that they output. The reason for this is that the more BTU the unit has, the more square footage it can cool down, and the larger (and heavier!) the AC unit will be.

The unit is heavier because it needs larger parts that can do more work if it is going to remove more heat (more BTU) from the air. The weight varies based on the materials used in each system.

Air Conditioner Type Weight Range in Lbs Weight Rang in Kgs
Central AC 70-85 lbs. 31-38kg
Window AC 45-130 lbs. 20-59kg
Mini Split AC 75-275 lbs. 34-125kg
Portable AC 50-100 lbs. 22-45kg
RV AC Units 80-250 lbs. 36-113kg

Determining The Weight Of Air Conditioners Per BTU

The weight of an air conditioner unit does not directly correlate to the BTU. However, the greater BTU, typically the greater the weight of the AC unit.

The reason that BTU affects the AC weight is that the higher the BTU number, the more likely the AC unit will need to have larger materials and therefore be heavier. BTU is an acronym for British Thermal Unit and is a measurement that measures how much energy is used when heat is extracted from your home.

BTU is important to consider when purchasing a new AC unit because the BTU number can tell you how much space the AC unit can cool.

For a room that is approximately 600 sq ft., the BTU should be 12,000 BTU or 1 ton AC. This breaks down to approximately 20 BTU per 1 sq ft.

Air Conditioner Rating (per BTU) Weight in Lbs Weight in Kgs
12,000 BTU 70-80 lbs. 31-36kg
24,000 BTU 140-160 lbs. 62-72kg
36,000 BTU 210-240 lbs. 93-108kg
48,000 BTU 280-320 lbs. 124-144kg
60,000 BTU 350-400 lbs. 155-180kg

Determining The Weight Of Air Conditioners Per Ton

Determining the weight of air conditioners per ton is relatively easy. For every 1 ton AC unit, the weight is approximately 40-120 lbs or 18-54kg. That simply multiples as the tonnage increases. The tonnage refers to the amount of heat that the AC unit can successfully take out of the air each hour.

Homeowners often want to refer to the ton or BTU amount of an AC unit before purchasing. These amounts can determine how much space the AC unit can cool. One ton typically moves 12,000 BTUs per hour, which equates to 600 sq ft.

AC per TON Weight in Lbs Weight in Kgs
1 40-120lbs. 18-54kg
2 80-240lbs. 36-108kg
3 120-360lbs. 54-163kg
4 150-400 lbs. 68-181kg
5 200-450 lbs. 90-204kg

What Makes The Air Conditioner Heavy?

Air conditioners are heavy for a couple of different reasons. Air conditioners weigh between 45 and 250lbs. Large commercial air conditioners, however, can weigh as much as 5,500 lbs. Window air conditioners are the lightest AC units available, weighing between 45 and 130lbs most of the time. The AC units vary in weight due to type, size, and the materials that make up the unit. While type and size do play a factor, the materials (and amount of materials) make up the majority of the weight.

Copper is one of the materials that is often used in AC units and contributes to heavy AC systems. The reason for this is because copper is used in multiple elements of air conditioning units: evaporator, compressor, and condenser. Aluminum is another material that is used in AC units and is lighter in weight compared to copper, but it does not conduct as well. Copper tends to be used because it removes heat from homeowner’s air much better than aluminum does, even though copper weighs nearly 560 pounds per cubic foot and aluminum only weighs 170 pounds per cubic foot.

People Also Ask (FAQ)

How heavy is an outdoor AC unit?

An outdoor air conditioner unit typically weighs between 130 to 250 lbs. The unit’s design contributes to the weight. Outdoor AC units are one of the heavier AC unit types on our list.

How heavy is a condenser unit?

A condenser unit typically weighs between 60 and 120 lbs. The more expensive your AC unit, the more the condenser will weigh. The reason for this is that high-quality AC condenser units are made with both steel and copper, which are heavy materials.

How much does an AC coil weigh?

An AC coil weighs anywhere between 60 and 120 lbs. The weight of the coil tends to be relative to the size of the AC unit. The larger the AC unit, the larger the evaporative AC coil will be within the unit.

Why are air compressors so heavy?

Air compressors are so heavy because they contain copper. Copper is a heavy metal and a vital one for AC systems. Copper weighs approximately 550-560 pounds per cubic foot. In AC units, copper tends to make up 30-60% of the entire unit, which creates a lot of weight.

Conclusion

Air conditioner units vary greatly in size and weight. Most units fall between 45-250 lbs, while large commercial AC units reach 1,200 to 5,500 lbs. The more high-quality and expensive air conditioner units tend to weigh more because of the amount of copper and steel used. However, window air conditioners and other smaller units are the exceptions to this rule because companies want to create streamlined, lightweight units and will spend more money to do so.
