When you are relaxing at home on a hot summer day in your comfortable and cool space, have you wondered what is inside my air conditioner unit and how it works? The cooling comfort you experience is the work of perfectly designed machinery, and modern HVAC systems do not only provide efficient cooling but more cost-effective and environmentally friendly service.

Important Components Inside Your HVAC System and its Functions

Compressor:

It is the most important part of your HVAC system. It helps compress gas into a liquid using the refrigerant, which helps in cooling. The size of the compressor varies according to the size of your AC unit. Regular service appointments will help in preventing any long-term damage to the compressor.

Evaporator coils:

It is fitted inside the indoor unit of your HVAC system and receives the hot air that is blown on the surface of the cool evaporator coils, which helps in heat extraction and cooling of the air. These are made up of aluminum or copper. These coils require annual cleaning by professionals to avoid any clogging.

Condenser coil:

It is the opposite of the evaporator coil. It is located on the outdoor unit of your HVAC system, and Its function is to transfer heat from the refrigerant and expel it outside. The heat you experience when you stand out in front of your outdoor unit is because of the working of the condenser coil.

Thermostat:

It is used to adjust the temperature setting and conditioning of your AC Unit and determines the cooling cycle of your HVAC unit. Improper placement and accumulation of dust can prevent it from accurately reading the temperature, which will put an energy load on the compressor. 

Air filter:

It prevents dust and debris from entering the HVAC system to circulate good-quality air. It would be best to clean your air filters to ensure maximum cooling efficiency regularly. 

Thermal expansion valve:

It helps regulate the liquid formed during the compression process and guides the compressor to switch on and off.

Refrigerant:

It is the cooling chemical circulated through the HVAC System and converts hot air into cool air. The most commonly used refrigerants are R-410A and R-22, which run within a network of copper evaporator coils. 

Fan:

It is found in the outdoor unit, and it helps release the hot air from the condenser coil to the outside. It also helps in the circulation of air within the unit to prevent overheating any parts. Ensure you do not obstruct the fan’s outlet and trim all plants and bushes around it to prevent overheating. 

Age and Energy Consumption of Your HVAC Unit

Always understand the EER (energy efficient rating) of a system which denotes its energy performance, by calculating the ratio of the useful cooling output divided by electricity input.

A higher EER ratio means that an air conditioner will provide you with a lot of cooling effect for every Watt of energy you provide. You want to invest in an appliance with high EER.

The day of installation will also determine the lifespan of the unit. The non-aggressive installation will increase the life of the machinery. 

Conclusion

The cooling effect you experience is the work of all these components combined, and damage to any one part can affect the overall working of the system.
