Selecting the right air conditioning unit can save you a bundle in energy costs. However, many people do not understand the language of HVAC systems and end up purchasing an inefficient system for the desired space. There is much to know about LG PTAC units, or packaged terminal air conditioning units. Learn the terminology for these units to ensure you select a system that will fit your unique cooling needs.
BTU
British Thermal Unit (BTU) is a measurement of energy used internationally. It measures the amount of heat an air conditioning unit can remove from a room. As the BTU rate increases, so does the cost of the unit, the weight, and the size. Standard LG PTAC units can range from 5,000 to 24,000 BTU. When shopping for AC units, it?s important to match the BTU rating to the size of the room. If the BTU is too low, it will not be able to keep a room constantly cool.
EER
Energy Efficiency Ratio (EER) is determined by dividing the BTU by the number of watts. More efficient AC units have a higher number EER. However, with a higher EER rating, the price of the air conditioning unit will go up. For many people, the long-term energy savings are more important than the initial investment of the cooling system. EER ratings on AC units generally range from 8 to 11.5. Hot climates require an EER of 10 or more.
Fan and Filter
The fan of an AC unit is used to move air. It?s important for a unit to have a sufficient fan speed in combination with an adjustable thermostat. Filters are used to keep the air clean. AC filters require regular replacements to ensure high quality indoor air. It?s crucial to have a HVAC specialist perform scheduled maintenance on any AC units in the building to ensure that the fan, filter and other parts are working properly.
