Air Conditioner In St. George

People often confuse the size of the air conditioner with its dimensions. In reality, the AC size refers to its cooling capacity, which is measured in British Thermal Units (BTUs). A higher BTU means faster cooling and vice versa.  

The ideal sized AC should perform effectively and operate at a low cost. The AC should be selected as per the room space. Hence it is essential to calculate the area the AC is supposed to cool to make an informed decision about purchasing the AC. 

Calculate your room area

According to St George air conditioning experts, the cooling area of a rectangular room is calculated as the product of the length and breadth of the room and further multiplied by 25 BTUs. The resultant figure represents the cooling capacity of the AC needed for optimal cooling. 

For a triangular room, it is calculated by multiplying length and breadth and dividing it by 2. For a room with no definite shape, it needs to be divided into rectangles and triangles. 

Purchasing an AC of the correct size is important because a smaller AC will only increase the energy cost without much cooling. A large size AC will cool faster but will remove moisture from the room; hence will need an additional purchase of a humidifier. Also, it will make people catch a cold due to temperature differences. The large AC will be switched on and off so frequently that it may put a load on the compressor of the AC. 

Factors affecting the calculation of BTU:

  • For rooms with ceilings higher than 8ft, an AC with higher BTU should be chosen for optimal cooling. Rooms with less than 8ft height should install AC with a lesser BTU.
  • Sunlight is an important factor in determining optimal AC. A room receiving abundant sunlight should increase the required BTU by about 10% for proper cooling. Darker, shady rooms should decrease the required BTU by 10%.
  • The cooling capacity of an AC is directly proportional to the number of room occupants. The more the number of occupants, the more is the cooling capacity required.
  • The required BTU should be increased by 4000 units if the AC is to be installed in the kitchen.

Buying an AC is an investment. Therefore, AC should be selected with utmost care. Also, even the best air conditioner can work optimally only when installed correctly. Therefore, it is recommended to use a professional air conditioning service in St. George.
