Picture it: Your eyes start to glaze over, but you continue to nod your head as if you understand what the HVAC technician is explaining. Unless you work in the industry, understanding HVAC maintenance and its terminology can be confusing. But as a homeowner in McKinney, TX, it’s important to at least know the basics when it comes to your system, so you don’t feel as though you’re at the mercy of your HVAC company.

HVAC Service Terms

Whether it’s time for routine maintenance or you need emergency service, knowing basic terminology is important. HVAC stands for heating, ventilation and air conditioning. Together, these three components keep your unit running efficiently as possible.


In your system, there are two types of coils. The one inside the outdoor unit is called the condenser coil, and the one inside the indoor unit is the evaporator coil. These coils’ primary functions are to increase and decrease the temperature inside your home.


Ductwork is a system composed of synthetic or metal tubing that moves the air from your air conditioner, heater or ventilation system, which is then circulated throughout your home.


Typically found in your outdoor air conditioning unit or heat pump, this important component compresses or pumps refrigerant to maintain comfortable indoor temperatures.

Split System

Similar to central systems, split systems also have two components: an indoor unit and an outdoor compressor with a condenser. The conduit links the indoor and outdoor units together.

Heat Pump

A heat pump heats and cools your home by drawing heat from outside air and circulating it through your ducts or moving heat from your home and releasing it outdoors.
