AC & Heater Repair in San Antonio

Common AC Terms Everyone Should Know

Confused by the HVAC lingo your air conditioning repairman uses? Don’t worry, you’re not alone. Unless you’re an expert technician, understanding the terminology isn’t easy. However, familiarizing yourself with a few common terms can help you communicate with your repairman or shop for new equipment when you need it:

Air flow – The amount of air your duct system moves. Air conditioners are typically designed to move approximately 400 cubic feet per minute, but in dry climates, that number can be higher. And in humid climates, it can be lower.

Compressor – The part of your AC that sits on the outside (aka, the condensing unit). The compressor’s job is to raise the temperature and pressure of the refrigerant.

HVAC – The acronym for heating, ventilating, and air conditioning.

Latent heat – The heat you need to remove from the air to lower the moisture.

PTAC – This stands for Package Terminal Air Conditioner and is the type of wall unit you usually see in hotel rooms. PTACs contain all parts of the AC in one box.

Refrigerant – The working fluid in your air conditioning that carries heat. Today, most ACs use R-22 or R-410a.

SEER – A term used to rate the efficiency of central air conditioners. Nowadays, 13 SEER is the minimum you can buy.

Sensible heat – The heat you need to remove from the air in order to lower the temperature.
