What Size Air Conditioner For a 14×70 Mobile Home?

There is much you will have to consider when air conditioning installation. But these considerations are essential if you’re working on a project for a mobile home. And this situation is particularly relevant if your project concerns installing a 14×70 mobile home. So what size air conditioner should you use for this type of house?

A 14×70 mobile home requires an air conditioner of at least 1.5 tons. One thousand square feet home can use an air conditioner rated between 18,000 to 21,000 BTU.

This air conditioner unit will ideally fit your mobile home without any problems, as it will be energy-efficient and will cool down your mobile home fast and run cool for a long time.

How Are Air Conditioners Sized?

British thermal units - How Are Air Conditioners Sized?

Air conditioners are sized according to several factors:

  • Cooled area’s square footage
  • Insulation levels
  • Window sizes

The larger the home, the larger the air conditioner needs to be for it to be effective. Air conditioner units can be installed indoors and outdoors, and they are usually purchased from specialized dealers or contract installers.

Air conditioners are sized by their cooling capacity in British thermal units (BTUs) per hour. The larger the BTU rating, the more cooling power the air conditioner has and the larger area it can cool. All air conditioners have a matching evaporator coil component; their manufacturer usually matches them, but you can buy a different size coil if needed or desired.

What is Tonnage? 

Tonnage to determine an AC unit’s size is different from tonnage as a measure of weight.

It measures the amount of heat that an air conditioner can remove from a home in an hour for air conditioners. The higher the number, the more dynamic the air conditioner.

Two main factors determine how many BTUs of cooling your home needs:

  • How well insulated the house is
  • What kind of climate the house is in

Suppose a well-insulated home is located in a cool climate where it doesn’t get too hot outside. It may need significantly less cooling capacity than an older home with poor insulation located in a hot climate like Texas.

What Size AC Unit for a 14×70 Mobile Home?

If you have a 14×70 mobile home, you’ll need a 1.5-ton capacity air conditioner to cool it properly. To find the proper extent air conditioner for your home, multiply the square footage of your home by 21,000 BTU.

However, several other factors will determine your mobile home’s suitable air conditioning unit. 

Your climate – Some country regions require more or less AC power than others. For example, people living in Florida should add about 5,000 BTUs for every room that faces west or south.

The number of people who live in – every person in your home creates about 600 BTUs per hour of heat. So, for example, if you’re single and alone in a mobile home with 1,500 square feet, you can use an AC unit with about 30,000 BTUs.

The number of windows and doors – Windows and doors let the outside air into your home and increase the amount of heat inside the mobile home. 

Factors to Consider When Purchasing an AC for Mobile Home

Factors to Consider When Purchasing an AC for Mobile Home

When purchasing an air conditioner for your home, you have many options.

Size. The size of the area classifies the amount of cooling capacity that your AC unit will require. By multiplying the room’s square footage by 25 BTUs (British thermal units), you can calculate this.

Cooling capacity. When it comes to the cooling capacity of your AC, the size will matter. As a general rule, you need 20 BTUs of cooling power per square foot. 

Efficiency rating. The energy efficiency ratio (EER) rating tells you how efficiently the air conditioner uses energy at peak usage times. A higher EER rating means lower electric bills over time. 

Window vs. portable AC unit. Consider a mobile AC model if you have a room without windows or want to move your AC from room to room. 

Climate and weather. If your home is in a hot area, you will need an air conditioner to cool your home better than one used in a more extraordinary area. It would help if you also considered how often it rains or snows and whether or not there’s frequent fog or heavy dew points.

Type of fan. You can choose between a two-speed fan and a variable speed fan. Variable speed fans are quieter than two-speed ones, but they use more electricity higher electric bills.

Price. You will want to determine your budget. If you can pay more upfront, you can expect to get a higher quality unit that will last longer and may need less maintenance than units that cost less.

What Size AC Unit for 16×80 Mobile Home?

Most of the time, a 16×80 mobile home will require about 3 tons of AC unit (36,000 BTU) capacity. Although it covers an area of 1280 sq. ft, it will be enough to keep your mobile home cool.

It’s essential to ensure your AC system has enough power to cool your home effectively. If you go too small, the system may not keep up with the size and heat of your home. , If you go too large, you’ll waste energy cooling your house faster than necessary.

Size & Capacities of Air Conditioner For Mobile Home

Size & Capacities of Air Conditioner For Mobile Home

Mobile homes, by definition, are constructed on or close to the ground. Therefore, they require a certain amount of cooling power to remain comfortable in summer and winter climates.

The size and capacity should be based on the following considerations:

  1. The area being cooled: indoor vs. outdoor;
  2. Type of installation: window unit vs. wall unit;
  3. If a furnace is also present: single-stage vs. two-stage;
  4. If a heat pump is present: single-stage heat pump or two-stage heat pump;
  5. Size of mobile home: interior or exterior; and
  6. Whether or not an air cleaner has been installed with this air conditioner.

To calculate the size and capacity of your Air Conditioner. First, find the total number of rooms in your mobile home. If you have more than 1 or 2 bedrooms, use the total square feet for each room. Then multiply that number by .75 to determine how much square footage you will need for each room.

For example, if you live in a 10-room mobile home, you could get two AC units with 2,000 watts each. On the other hand, if you live in a 6-room mobile home with three bedrooms and one full bath, you could get one AC unit with 3,000 watts and one kit air conditioner with an output of 1,500 watts.

How many BTU do I need for a single-wide mobile home?

25-30 BTUs per square foot is adequate in warm weather as a natural rule. However, in colder regions, you may require up to 45 BTUs per square foot and then multiply this by the number of square footage in your mobile home to determine how many BTUs you will need.

Small Mobile Homes: 5,000 – 10,000 BTUs

Medium Mobile Homes: 10,000 – 15,000 BTUs

Large Mobile Homes: 15,000 – 20,000 BTUs

BTUs of Heat per Hour

Air conditioners have a cooling capacity ranging from 5,000 to 25,000 BTU. The larger the area of your home, the more BTU you will need.

BTU stands for British Thermal Unit, the amount of power needed to heat 1 pound of water by 1 degree Fahrenheit.

1-ton air conditioner is capable of removing 12,000 BTUs of heat per hour

1 ton = 12,000 BTU/hour

2 tons= 24,000 BTU/hour

3 tons= 36,000 BTU/hour

4 tons= 48,000 BTU/hour

5 tons= 60,000 BTU/hour

For example, A 2-ton air conditioner can remove 24,000 BTUs in an hour. It is roughly equivalent to the heat produced by melting 3,600 pounds (or 1.8 U.S tons) of ice in 24 hours (equal to one day). The result would be a temperature change from 32 degrees Fahrenheit (0 degrees Celsius) to 212 degrees Fahrenheit (100 degrees Celsius).

How many square feet is a 14×70 mobile home?

A mobile home that measures 14 feet by 70 feet is 980 square feet.

To calculate the total square feet of a square or rectangular room, you multiply the length by the width. 

 Length feet × Width feet = Square Feet

 14 × 70 = 980

 14×70 room = 980 square feet

Note that square feet can be shortened to sq ft or simply ft2. Therefore, the answer above can be simplified as 980 ft2.

How do I calculate what size air conditioner I need?

You can calculate the size air conditioner you need based on the size of the room, your climate, and how often you use it.

Calculate your square footage. To find the square footage of your home, multiply the length by the width of each room and add it together. For example, if you have a 10×15 foot room, you would multiply ten by 15 to get 150 square feet.

Multiply your square footage by 20. You can multiply the total square footage by 20 to determine how many BTUs of cooling power your air conditioner needs. For example, if you have a 1,500 square foot home, you would multiply by 20 to get 30,000 BTUs.

Adjust based on the following factors. Department of Energy and U.S. Environmental Protection Agency) recommends the following.

  • If your home is shaded, subtract 10% of the capacity. 
  • If your house gets too much sunlight (in Phoenix, Arizona), increase your power by 10%.
  • If your property is tied-up by more than two people at a time, increase the capacity by 600.
  • If you’re acquiring an air conditioner distinctively for your kitchen, add 4,000 to the power.

Use this square footage calculator to help you identify the area of your room. 

How many square feet is a 16×70 mobile home?

A 16-foot-by-70-foot mobile home is 1,120 square feet.

To calculate this, we multiply the length by the width. In this instance, that means multiplying 16 by 70 to get 1,120.

If your mobile home is 16 feet wide and 70 feet long, its square footage is 1120 square feet. That’s a great size for many mobile homes, as it’s enough space that you can give each room the care it needs. It’s also large enough to fit a full-sized dining table, which means you’ll have enough room to entertain guests and host family gatherings.


In general, choosing an air conditioner will depend on the number of rooms to be cooled and the type of climate in that particular location. Air conditioners are usually available in capacities ranging from 5,000 to 50,000 BTU/h. 

The best size of AC will be selected based on the total area (sq. ft.) to be cooled and the climate where the mobile home is installed. You may also consider electric heating in cooler areas, especially mountainous regions.
