What’s the Magic In Your Air Conditioner?

First, no single part of your air conditioner unit makes the air cool. Several components work together to achieve ideal temperatures in your home. Converting liquid refrigerant to gas absorbs heat.

Your air conditioning unit performs this task repeatedly, and it expels the cool air in the process. Air conditioning units operate using a basic system:

  1. Warm air is drawn in from your home, usually through a grille.
  2. A fan blows the warm air over evaporator coils, which contain refrigerant.
  3. Because the refrigerant is cooler than the incoming air, the heat is transferred to the refrigerant. This leaves the air dry and cool.
  4. Once the air is cooled, it’s sent back into your home through the ductwork and vents.
  5. While the cool air is delivered, the refrigerant is processed through the condenser coils and compressor. The heat absorbed by the refrigerant is released outside, and new refrigerant is pumped back through an expansion valve.
  6. The refrigerant is cycled back to the evaporator coil, to start the entire process over.

Essential Parts of an Air Conditioning Unit

Every air conditioning system has small variations, depending on the brand and settings. However, the essential components are the same in every unit. Knowing the essential pieces of your air conditioning unit will help you to know when something might be wrong with your cooling system. Below are common components to know:

  • Refrigerant: This special substance can change from liquid-form to a gas at very low temperatures. Older air conditioners used environmentally harmful Freon®, and its use in new air conditioners was banned by the government starting in 2015.

    The refrigerant option now is Puron®, which is healthier for the environment. When the refrigerant is low, your air conditioning system will stop producing cold air and just cycle warm or hot air into your home.

  • Evaporator Coil: This coil is responsible for converting the liquid refrigerant into a gas. These coils can occasionally freeze over, and this will prevent your air conditioner from operating correctly.

  • Fans: The blower fan keeps air moving throughout your whole system. When air isn’t coming out of your vents, the problem may be a bad fan. The best way to diagnose if your fan needs to be repaired or replaced is to call KS Services and schedule an HVAC repair.

  • Ductwork: Hot air pulled into your air conditioning unit and cool air dispersed back out travels through connected ductwork throughout your home. Regular inspections of your ductwork will help to detect interference in your air conditioner’s performance caused by holes, gaps or leaks.

  • AC Compressor: Working as a large electric pump, the compressor operates with the condenser. It uses pressure to turn the gas refrigerant back into a liquid. If the compressor goes out on your air conditioning unit, it’s expensive to replace. Upgrading to a new unit is more cost-effective than replacing a failed compressor.
  • Condenser Coil: As a counterpart to the evaporator coil, the condenser coil works to bring the hot, condensed refrigerant gas back outside. It then vents the heat and turns the refrigerant back into a liquid form.

Understanding the basics of your air conditioning system and how it works will help you make smart decisions about future maintenance and HVAC repairs.
