With summer just around the corner, it’s time to tweak up the performance of all the HVAC systems. You may be aware of the fact that all the HVAC systems in use today need to be maintained periodically. Though many people just ignore the maintenance of the HVAC systems, it is just indispensable for the effective performance of the systems to ensure optimum comfort. Ignoring this maintenance will damage the components of the HVAC systems, thereby making them supply stale air in the room. Stale air circulation in the room will be greatly hazardous to health. This article is all about the regular maintenance procedures required for the HVAC systems.

Air filters are the components that needs regular cleaning. So, before getting into the maintenance of HVAC systems, let’s see the types of air filters used.

* Mechanical air filters – These air filters are disposable. They collect the dust particles present in the air and stores them in a medium. These filters should be replaced with new ones regularly.

* The Electronic air filters – As the name indicates these filters work on the electronic principles. These filters are found to be more efficient when used along with the mechanical ones.

* Gas absorption air filters – Though these air filters are not that effective in collecting the dust particles, they can easily remove the bad odor from the air.


All the above mentioned air filters used in Refrigeration units require different approaches for maintenance. Most of the mechanical air filters need to be replaced with new ones periodically. The replacement time depends on the amount of dust accumulated in the filter. There are washable mechanical filters too which can be washed and reused several times before they need to be replaced with new ones. The electronic air filters just need to be cleaned in a bi-annual basis. In the event of gas absorption air filters, manufacturers claim that these filters can last for 3 months. After three months the carbon used in these filters will loose its filtration properties and the refrigeration system has to be fitted with new filters.

The Career opportunities for Heating, Ventilation & Air Conditioning Technology

As the refrigeration units require regular maintenance, the Heating, Ventilation & Air Conditioning Technology professionals are in great demand today. Moreover, the maintenance of HVAC systems used in the marine systems and the food processing units are sophisticated. Anyone can learn this sophisticated technology today from the HVAC Schools. HVAC schools are considered to be the best for learning this technology because of the top quality education offered in these schools. Some of the best HVAC schools provide great placement assistance too. Hence if you are looking for an aspiring career, the HVAC schools are the ones to look for.
