What Size AC for 2000 Sq Ft? (Answered)

In this hot, blazing sun, life is harder without an AC. Plus, the right size matters a lot. As in jumbo-sized rooms, people often experience less airflow.

This typically happens with the rooms having an area of 2000 sq ft. Looks like it is too tough to get the perfect match!

AC size for 2000 sq ft

For a room of 2000 sq ft, one must take a greater size of AC. Again, not too big. Thus, by accurate measurements, your HVAC needs would suffice within 3.5 to 5.0 tons. This is equivalent to 42,000 to 60,000 BTU, quite similar to a room of 1600 sq ft.

However, the requirement may vary from room to room and place to place. A commercial area of 2000 sq ft can require more heating and cooling power than a residential one needs. Thus, don’t jump to the conclusions.

Most of the time, this is ensured by a serious calculation of HVAC by experts and field monitors. However, at home, anyone can try a simple orientation of this.

For instance, in residential rooms of 1600 sq ft, more than 12,000 BTU of air can be transferred in an hour. But the tables are turned when you are talking about commercial space.

Due to several factors, their airflow can be affected. The commercial areas have higher walls, greater people, and significant insulation. This all sums up to change the calculation.

Thus, often, these large areas have low airflow. And requires a greater cooling effect than your home.

Luckily, this isn’t the case for residential ones. As they have fewer windows, people, and insulation, the chances to lose cold air are quite less. So, it’s safest to assume they need one ton of air conditioning per 400 square feet.

Other than this, you can also look into other aspects. The climate and the weather surrounding the house are also crucial. As this thing alters the general rule, a bit of expert advice would help out in such cases.

Also, there is a budget factor. Not all the AC have the same power consumption and same costs. Therefore, frequently, this can cause trouble for your well-devised plan. No wonder, professionals suggest checking these beforehand.

How do I calculate what size air conditioner I need?

Calculating the size of the air conditioner is heavily crucial. Every homeowner needs a bit of knowledge of this. Believe it, it’s not that hard. Rather, simple mathematics is all you need.

Firstly, you need to know the length and width of the space. To do this, a simple measurement can help. Use a measuring tape and find that out in a go.

When done, you need to multiply them. By doing this, what you get is the area of the entire space. To illustrate this, if your room is 15 feet wide and 20 feet long, the area would be 300 square feet. Simple!

Next, you need to multiply the obtained value by 25. It is the most suitable value for air conditioning taking into account every type of climate, even humid ones.

To put it simply, multiplying 300 by 25 gives 7500 BTU. This is exactly the cooling effect your home needs. No ifs or buts.

If one wants to try a larger one with greater BTU, they are obviously welcome. But a smaller one can be an awful mistake in several ways.

Not only it will fail miserably while providing cool air, but will also consume more wattage. As a result, get ready for high bills.
