How Does an Air Conditioner Work and How Should it be Maintained?

Your air conditioning system keeps your business or home cool during the hot summer months, but have you ever wondered how it works? One thing you might not know is that your air conditioner and refrigerator work primarily in a similar way. The difference is that your refrigerator cools a small, enclosed space, and an air conditioner keeps your home, commercial, or office space at a cozy temperature.

The whole process of cooling the air in your property is based on a very simple scientific principle. The rest is achievable by mechanical means. Take a look at how air conditioning works to keep your residential as well as commercial spaces cool.

The Process of Cooling Your Home with an Air Conditioner Unit

Air conditioning units work by removing warm air from inside your house or office and transferring it outdoors, while releasing cool air back into the room, thus reducing the temperature. The unit consists of three components that manipulate the state, pressure, and temperature of the refrigerant, allowing the AC to effectively do its job. They include:

  •   Evaporator
  •   Compressor
  •   Condenser

Step 1: The warm air from inside your room is drawn in through an expansion valve that regulates the flow. It is then blown over the cold evaporator coil that absorbs the heat from the air, cooling the air. As the refrigerant in the coils absorbs the heat, it then changes into a gas and moves to the compressor.

Step 2: The compressor acts as a pump. It decreases the volume of the gas and increases its temperature and pressure for the next process.

Step 3: The AC condenser then takes the heat collected from inside the room by the refrigerant – which is now in vapor form – and pumps it outside. The outside air absorbs the heat and lowers the temperature of the refrigerant, changing the state from a gas back into a liquid.

Once the heat is removed to the outdoors, the cooled refrigerant travels back indoors to the evaporator to go through the process all over again. This process repeats itself until the inside temperature of your building reaches your desired level. At this stage, your thermostat tells your AC unit to shut off.

How to Do Proper Maintenance on Your Air Conditioner

It is important to know how your AC unit works. However, it is equally important to know how to conduct proper maintenance on it. The hot summer months will soon be here, which means that it is time to make sure your unit is in good shape to keep your home and office cool throughout the season.

Keep the Filters Clean or Replace Them

This is the most important maintenance task that will ensure the efficiency of your AC. Check the unit’s filter to see if it needs cleaning or replacing. If you see visible debris or too much dirt on the filter, it probably needs to be replaced. Clogged or dirty filters will not only put excessive strain on the unit but will also impact your room’s air quality.

Clean the Coils

Air conditioning coils assist the unit’s refrigerant in absorbing the heat and cooling the area. The coils tend to become covered in dirt and particles that reduce their ability to absorb heat. This makes the air conditioning unit work harder to maintain the room’s temperature, resulting in a less efficient system. This also means your summer utility bills will be through the roof!

And because the AC coils are sharp and risky to touch, it is advisable to have them checked by professionals during periodic maintenance. Give Pro Service Mechanical a call for an excellent job.

Check the Fins

Inspect the unit’s fins to see the amount of debris and dirt on them. Remove the outer covers and clear away visible dirt using a shop vacuum. After that, spray the remaining debris away using a garden hose. Once they are clean, check to see if there are any bent areas that could tamper with the airflow. If bent, use a butter knife to straighten the fin back into place.

In conjunction with this, make sure to rake away leaves and other dirt around the unit. Cut back shrubs and branches for easier airflow.

Check the Condenser Unit Fan and Ensure it is in Proper Condition

The condenser unit fan is important because it cools down the refrigerant gas. If you hear a weird sound coming from your air conditioning unit, there’s a possibility that the unit fan is at fault. Contact the professional experts immediately to check for heaviness in the motor or examine any cracks in the blades.

Regular Professional Maintenance

Proper maintenance for your AC is not only done to save electricity bills but also to prevent equipment breakdowns, especially when you need it the most. Ensure you have your AC unit serviced by the AC experts at the recommended periods to get optimal performance. The experts have the nous to troubleshoot and examine your unit for any issues it might have and make the right repairs.
