Any questions about air conditioning units.
What Are The Types Of Air Conditioners?
Air conditioners come in different styles and types. For central HVAC there are package and split style units that can be a heat pump or an air conditioner with a gas furnace. Smaller units we work with are mini splits and are best for cooling/heating individual rooms.
What Are The Sizes Of Air Conditioners? (Tonnage?)
The tonnage is how big it is and is a measurement of how much heat in B.T.U.’s (british thermal units) an air conditioner or heat pump is capable of removing from a home. Every 12,000 B.T.U.’s is one whole ton. For example, if you have a 3-ton unit then 36,000 B.T.U.’s are capable of being removed. It doesn’t tell you how efficient it is.
What are Heat Pumps And How Are They Different From Air Conditioners?
Heat pumps and air conditioners both cool the same by removing heat from the home, their main difference is how they heat the home. Heat pumps are able to heat with their same components that cool and air conditioners are typically accompanied by gas furnaces for heat. Heat pumps are able to achieve heating with the same components because of a reversing valve that reverses its flow of freon, so instead of removing heat from the home to cool, it picks up heat from outside and brings it inside.
What Are Split Style Units?
Split style air conditioners and heat pumps have their components separate from each other, they are split apart. Typically, this is the style of unit you see when the air conditioner is outside on the ground, that’s actually just one-half of the system being the condenser coil, condenser fan, and compressor. The other part is the evaporator coil with a fan inside an air handler in the attic. All the ductwork connects to the air handler at plenums. Copper linesets connect flowing Freon for heat transfer from the evaporator to the condenser. There are also smaller units called mini splits for individual rooms.
What Are Package Style Units?
Typically, package style units are when the air conditioner is on the roof and all the components are in one cabinet. This means the condenser, compressor, evaporator, and fans are all in one cabinet connecting to ductwork in an attic.
