HVAC Terms to Know for the Cooling Season

June 14, 2016 | Blog

HVAC Terms to Know for the Cooling Season | CCACAs summer heats up in the Corpus Christi area, you will want your air conditioner to run without any issues. Unfortunately, sometimes the best systems suffer problems. This is when it is good to know the following HVAC terms so you can communicate the problem clearly to an HVAC technician.

Split System

This is a common type of air conditioning system. It consists of an indoor section and an outdoor section.

Central Air Conditioner

In this system, air is cooled and then it is distributed throughout the home via ductwork. This differs from ductless mini-splits, window air conditioners, and similar systems that cool only single areas without ductwork involved.

Air Handler

This is an indoor component and is also called a blower. It pushes air through the ductwork.

Evaporator Coil

This is also located as part of the indoor section of a split system. One of the most common problems associated with the evaporator coil is frost on the coils. A dirty filter or other airflow issues can cause this, and it requires prompt attention.

Compressor

This is in the outside unit of the air conditioner. Its job is to compress and pump refrigerant through the lines. A noisy compressor often signals problems.

Condenser Coil

Also called the condensing coil, this is located in the outdoor unit. Together with the exhaust fan, it assists in releasing heat from refrigerant.

Refrigerant

Refrigerant, also called coolant, changes from a liquid to a vapor during heat transfer. It pulls heat from the air in your home and deposits it as it travels outside. Low or leaking refrigerant will prevent your air conditioner from cooling as it should.

Refrigerant Lines

The refrigerant flows through these conduits. They connect the indoor and outdoor components of the system.

Zoning System

If you have one central A/C system, but you have thermostats that regulate individual climate needs for different home areas, then it is likely you have what is called a zoning system.

Great Company

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.

I’ve had a system purchased and installed by them for several years with the maintenance contract the whole time. I’ve been very satisfied with the service. You can’t go wrong selecting them for your business.
