Have you ever looked at your air conditioning system and wondered why it’s so big and how all the parts work together?

This post will provide a quick overview of some of the main parts of the AC and how they work. Read on to become more educated on your AC unit.

Condenser Unit

The condenser unit of the air conditioning system is the big box that is typically placed outside your home. It is most commonly referred to as the “outside AC unit” A condenser unit is like the powerhouse of an air conditioning system. Its many features set the rhythm for the entire AC and keep your home cool. Below is a list of the most common parts of the AC unit: 
  • Outdoor Coil
  • Scroll Compressor
  • Direct-Drive Fan
  • Cabinet
  • Coil Gaurd 
  • Drainage Holes
  • Capacitors
  • High-Pressure Safety Switch
Each of these parts has an essential role in the function of an air conditioner. If any of them break, they will necessitate an urgent repair from a 24-hour AC repair tech in Houston.


Contrary to the condenser unit, the evaporator is the indoor AC unit. This indoor device is what pushes the cool air produced by the condenser into the home. If you use a central air conditioning unit, the evaporator will be found inside the blower compartment. If you’re using a split system, the evaporator will be inside the big box attached to the wall. Much like in central AC, the evaporator coil will be near the blower fan.

Air Filters

Another essential part of an air conditioning unit is the air filters. As the air is cooled, it is pushed into the air ducts, through the air filters, and into the home. Throughout this process, the filters accumulate dust and debris. As a result, it is essential to ensure that your air filters are changed or cleaned at least every two months.

Keeping up with the maintenance of these filters is especially important. First, it ensures that the air we breathe is of the highest quality. Next, clogged air filters decrease the efficiency and longevity of the heater. As a result, each AC maintenance inspection includes checking or changing the filters. 

If you feel that the quality of your air has changed in a negative way, contact a local 24-hour AC repair tech in Houston for help.


The AC unit has two types of coils: the condenser coils and the evaporator coils. The condenser coils have the critical task of collecting the heat in order to cool it. After the hot air is cooled, it is pushed into the evaporator coils, which then push the air out into the ducts and through the vents. 

Many issues can go wrong with these coils. For example, their efficiency will decrease if they accumulate too much dust or debris. They can also freeze if there is excess freon running through them. If you feel that the coils in your AC unit need attention, a 24-hour AC repair tech in Houston will help investigate the problem.


The air conditioning unit is science and chemistry at its finest work. Refrigerant fluids are also known as Freon. The AC uses this fluid to cool the hot air it collects before circulating it back into the home. This process is key to having a cool home when needed and ensuring optimal comfort levels. 

In order to work efficiently, the AC unit will require periodic refrigerant fluid maintenance. In fact, when an AC unit isn’t cooling the home as expected, Freon levels are the first to be checked by an AC repair tech in Houston.
