It works well to have a word with your HAVC contractor while planning on purchasing a new air conditioning system for your home.

CHOOSING THE RIGHT SIZE AIR CONDITIONER

You may possibly be wondering why it is important to buy the right sized air conditioner for your home. Air conditioners are believed to eliminate heat and humidity from the air. If the unit is too large it will cool the room quickly, but remove humidity, which leaves the room with a damp feeling. A right sized air conditioner will eliminate humidity effectively as it cools the room slowly, and if you end up purchasing an air conditioner with a lower than required capacity, it tends to consume a lot more energy to necessitate required cooling. Lower capacity units will save you on your capital cost but will expand the electricity consumption and also reduce the life span of the unit. Your room size governs your ac capacity. Follow the chart below to determine the A/C power one needs for a room

Room size

Required AC Size

0 to 80 Sq Ft

0.75 ton

80 to 120 Sq Ft

1 ton

120 to 190 Sq Ft

1.5 ton

190 to 300 Sq Ft

2 ton


Obviously, a room’s environment doesn’t depend just on square footage. If a room is exposed to excessive sunlight, it is important to extend the air conditioner capacity by about 10% and decrease the capacity by 10% for a shady room. If there are more than 2 people in a room it will be a good idea to add about 600 BTUs per extra person. While considering an A/C unit for a kitchen, keep in mind that your ovens and gas stoves emit a lot of heat which your air conditioner is expected to recompense. Therefore it is necessary to add 4,000 BTUs for the unit you install in your kitchen.
