Air conditioners and power consumption

Power consumption is greatly influenced by many factors. Some of them are: thermostat settings, size of the air conditioner, size of the room, insulation. Also the age of the air conditioning unit is very important.

Energy Start certification

Energy Start certified air conditioning units use less energy than unit produces before 2003, up to 10% less energy.

SEER – Seasonal Energy Efficiency Rating

The SEER refers to the number of hours an air conditioning unit works per year, divided by the electrical energy consumption measured in watt-hours. The higher the SEER the more energy efficient the unit is.

BTUs – British thermal units

This rating measures the capacity of air conditioning units. If the BTU is too high, than it will inefficiently cool the room, turning on and off all the time. This means higher energy costs. If the BTU is too low, the machine will struggle to maintain the temperature, running in longer cycles. You should buy a unit that has 20 BTUs for every square foot of your room.
