During the hot summer months in Nacogdoches, TX, your main concern with your air conditioning unit is probably that it keeps you cool and comfortable. Detailed knowledge of air conditioning unit function is not required for the average homeowner, but here at McWilliams Heating, Cooling and Plumbing, we want you to be aware of a few basics. Here are three things to know about the functioning of your air conditioning unit:

• An Air Conditioner is Multi-Functional: In addition to keeping your home cool, your air conditioner also serves as a basic dehumidifier and air purifier. During the air conditioning process, both heat and humidity are removed from the home. An air conditioner does not work as well as a dehumidifier, of course, but it does remove some moisture from the home. The air filter also traps debris and prevents them from circulating in the home. This is why AC services like replacing the air filter regularly are essential.
• The Main Components: Just a few main components make up an air conditioning unit: the evaporator, condenser, expansion valve, and compressor. Although the air conditioner is called a unit, a central air conditioning system actually consists of two main parts: one located inside the home and one on the outside. The evaporator is part of the inside components, and the condenser and compressor are located outside. During AC service, the technician, who is trained and familiar with these different components, will make sure these essential parts are all working properly so that your unit continues to function as it should.
• Energy Efficiency: The efficiency of air conditioning units is measured by SEER or Seasonal Energy Efficiency Ratio. An air conditioner with a higher SEER rating functions more efficiently and is able to cool air while using less energy than a lower SEER-rated unit. Keeping up with AC service will also improve efficiency since the components of your unit will function optimally when they are maintained.
