Before you call on your HVAC contractor about upgrading your A/C, you’ll need to get “in the know.” Heating and cooling terminology isn’t difficult to learn, but there’s no doubt about it: The HVAC industry has its own language.
When upgrading your A/C, here’s the lingo you’ll need to know.
Air conditioner components include:
- Refrigerant: A liquid/gas that runs through the A/C, refrigerant is designed to absorb and release heat throughout the cooling process.
- Coil: This is the tubing through which refrigerant flows. It can take on various configurations, such as an “A” or “N” coil, and help transfer heat.
Evaporator: Housed in the indoor unit, this coil helps in the heat absorption process.
- Compressor: This device compresses refrigerant so that it turns into a hot, high-pressure gas.
- Condenser: Another coil that is housed in the outdoor unit, the condenser helps to release heat.
- Expansion feature: This meters the flow of refrigerant, releasing it once it passes through the compressor.
- Plenum: Part of the general air conditioner unit inside the home, the plenum helps to distribute cool air into the home.
Aside from learning A/C components, when upgrading your A/C, you’ll likely hear your contractor use these terms:
- Btu/h (British thermal unit per hour): This is a number that will reveal the output capacity of an air conditioner.
- Watt-hour: Another term that experts use to evaluate system efficiency, watt-hours are simply a unit of power.
- Ton: This is another expression of air conditioner capacity. A/C system capacity is commonly described in terms of tonnage.
- Cooling load: This term shows how much heat is allowed to build up in a room when the A/C isn’t running. With this calculation, your technician can correctly size air conditioner capacity to meet the load.
With a little knowledge under your belt, you can “talk the talk” with your HVAC contractor. More so, HVAC terminology will help you make an educated decision and a wise investment that will pay well in energy savings for years to come.
