The 14000 BTU unit might start the fan and compressor at the same time while the 34000 BTU unit manages the startup current to something reasonable, like a soft-start. When it comes to the average power consumption the 34000 BTU unit has to consume more.

How much cooling capacity do I need?

Take the 180 sq. ft. times 25 BTU per square foot and you get the minimum BTU air conditioner you should buy. That means 180×25=4500 BTU cooling capacity is needed.

What does cooling capacity in AC means?





Cooling capacity indicates the amount of heat the system can remove from the refrigerated space over time. It is equal to the change in the specific enthalpy of the refrigerant in the evaporator caused by the refrigeration load multiplied by the mass flow rate of the refrigerant.

How many BTU do I need in my living room?

Consumer Reports recommends 20 BTUs per square foot of the living space (or spaces) you want to cool down.

How do you calculate cooling capacity of a room?

For a room, multiply its length by its width to get the square footage. Multiply the square footage by 20. This is the measure of the BTU cooling load of the space.

Does higher BTU use more electricity?

The more BTU your unit produces, the more energy it consumes. So, if you are worried about high energy costs, you should get a unit that is appropriate for your space.

Is more BTU better for air conditioner?





A measure of an air conditioner’s power is its BTU rating. BTUs are the energy used to remove heat from a room. Therefore, the more BTUs an air conditioner unit has, the better equipped it is to cool a larger space.

Is cooling capacity same as power consumption?

EER(Energy Efficiency Ratio)=cooling capacity of ac/power consumed by ac. cooling capacity of 1 ton is equal to 3.517 kW of power. =1.5*3.517/2.7=1.954 kW. AC consists of two units, Indoor unit which is called the evaporator and the Outdoor Unit which called the Compressor.

Is high cooling capacity good?

If your unit has too much cooling capacity, it will create large temperature swings in your home and won’t adequately dehumidify your air. Either case will also lead to inefficiencies and wasted energy.

How do I calculate aircon BTU?

All you have to do is to multiply the length of your room in feet by the width of your room in feet, and then multiply that by 25. That will give you the BTU needed to properly cool your room.

What is the formula for calculating BTU?



You may be familiar with the formula BTUH = CFM x ΔT x 1.08. This same formula is often rearranged to use for determining airflow by measuring the heat input and temperature rise.

How are cooling needs calculated?

Add together all the wattages for Servers, Switches, Routers and multiply by 3.5. Take the total wattage of the lighting and multiply by 4.25. Add all the BTUs together. This is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.

How much electricity does a 15000 BTU air conditioner use?

about 1,500 watts



An average 15,000 BTU RV air conditioner will require about 1,500 watts to run. However, it will need about 3,000 watts or even 3,500 watts start-up wattage.

What is the difference between 10000 BTU and 12000 BTU?

10,000 BTUs will cover 300 sq. ft. (2,400 cubic feet) 12,000 BTUs will cover 400 sq.

Is a higher BTU more efficient?

This is calculated by BTUs (British Thermal Units) divided by watts used. For instance, if you have a 12,000 BTU unit and consume 1200 watts in an hour, the EER rating is 10. The higher the rating, the more efficient the system is.

What size room will a 15000 BTU air conditioner cool?

about 875 sq. ft.



Air conditioners rated at 15,000 Btu should be enough to cool most rooms up to about 875 sq. ft.

What size room will a 12000 BTU air conditioner cool?

600 sq ft.

Answer: Using the EPA’s 20 BTU per sq ft rule of thumb, the room size of 12,000 BTU air conditioners is 600 sq ft.

How much space can a 14 000 BTU air conditioner cool?

500 sq. ft.



14,000 BTUs will cover 500 sq. ft. (4,000 cubic feet)

How many square feet will 34000 BTU heat?

How many btu do I need to heat 3,000 square feet?

Room/Area Size Heating Capacity(BTU)
500 sq ft 22,000-27,000 BTU
600 sq ft 27,000-33,000 BTU
700 sq ft 31,000-38,000 BTU
750 sq ft 34,000-41,000 BTU

How many BTU do you need?

Generally, your temperature control system should have 20 BTU for every square foot of living space in the area you wish to heat or cool. For example, if your room or area is 400 square feet in size, then you should opt for a temperature control system with a capability of around 8,000 BTU.

How many BTUs are in a ton of cooling?

12,000 BTU/hr

So, a one ton air conditioning unit has the capacity to cool up to 12,000 BTU/hr.

What tonnage is 34000 BTU?

2.8 tons

For example, the AC shown in the AHRI certificate below is a 3 ton air conditioner (36,000 BTU/hr) with an actual capacity of 2.8 tons (34,000 BTU/hr).

How many tons is a 34000 BTU air conditioner?

Common BTU to Tons Chart:

BTU Ton
28,000 BTU 2.33 Ton
30,000 BTU 2.5 Ton
34,000 BTU 2.83 Ton
36,000 BTU 3 Ton
