Air Conditioning Terms You Should Know: Beginner’s Edition

Bioaerosols, BTU, evaporator coil, thermidistat…Do you know what these words mean? While HVAC lingo can seem dull, knowing some basic air conditioning terms can benefit you, your system, and probably your wallet too. Here are some of the AC terms you should brush up on:


Let’s start with the basics. HVAC stands for “heating, ventilation, and air conditioning” and is a shortened term to describe the three main functions of the AC system. HVAC systems are intricate appliances that house a myriad of different parts—all which work harmoniously to provide your home with comfortable temperatures and increased indoor air quality.


An AC term you might have heard before, especially if you’ve ever purchased a new air conditioning system, is SEER. SEER stands for “Seasonal Energy Efficiency Ratio” and is basically a system used to rate air conditioners. A good thing to remember if you’re in the market for a new air conditioning system is the higher the SEER rating, the better the energy performance will be. This term is one you should know because it can save you big bucks—a system with a higher SEER rating may be more expensive than a lower rated one, but the amount you save on utility bills with a higher rated system could pay for the system itself in the long run.


The condenser is a major component of your HVAC system, so knowing what it is and how it functions could save you money. The condenser ultimately works to remove heat from the air through a process of pressurizing refrigerant. The condenser works alongside coils and a fan to remove this heat and keep your home cool. Like all appliances, sometimes things malfunction so it’s a good idea to know what a condenser is since a broken condenser can lead to increased electricity bills.

Heat Pump

A heat pump, despite what you may think the name suggests, actually works to cool your home through a process of moving heat. Heat pumps function differently depending on the seasons—in the winter heat is drawn from outside and circulated through your house, while during the summer months this process is reversed. Keep this HVAC term in the back of your head because it could help you save money since heat pumps use less energy than traditional AC systems.

Many people rarely acknowledge their HVAC systems until something goes wrong. Similarly, many don’t know basic AC lingo or that knowing some simple air conditioning information could save them money.
