How to Fix Most Common HVAC Issues

The HVAC systems are a necessity to keep the environment in big structures like offices, towers and retail properties healthy for the residents. With temperatures reaching critical points in concrete structures cooling systems are always under constant pressure. This takes a toll on the condition of these systems leaving them inefficient. This is why it is necessary to regularly check the HVAC systems so that they can operate in top condition.

HVAC maintenance is important to keep the machines working efficiently as it will keep their performance up and you will be saved from paying hefty power bills. I have been dealing with HVAC machines for over 20 years now and understand what common problems these systems face. Here I will be listing the most common issues HVAC systems face, and how you can fix them easily.

Restricted Airflow

One of the most common complains by HVAC users is the poor quality of airflow in areas of their property. There can be many reasons for the restricted airflow but most common is the clogged air filters. These filters are designed to trap the dust particles and prevent from entering the HVAC components. However, when these filters get overloaded they limit the air that passes through them causes a drop in the airflow. The easiest solution is to switch the filter every month.

If the airflow does not increase after a change of filters then internal components of the HVAC system are affected. When there is insufficient ventilation the evaporator coils freeze up causing disturbed working. This can cause entire HVAC system to suffer. In such situations, defrosting the coils is the only way to troubleshoot restricted airflow problem.

Leaking Ducts

Cooling and heating systems often have to deal with water damage. Especially during high humidity the drain pans that are designed to hold surplus water can easily become overwhelmed causing water reaching internal components. Leaking ducts are another reason for water damage and so are the frozen components that melt when the HVAC system is inactive.

If the problem is left unattended then the leaking water can also affect the surrounding walls and ceilings. Water damage is most severe because, by the time any external signs occur, the internal damage has been caused which is beyond control. To avoid any water damage you need to regularly perform maintenance checks of the HVAC systems especially the ones with chilled water.

HVAC system not cooling properly

Another common issue people face is the inadequate cooling during warmer months. When your air conditioner is running at full blast and still not cooling the air inside, the low refrigerant is the root cause. The refrigerant is required to transmit the heat in the air outside. An HVAC unit cannot do its job without enough amount of refrigerant flowing through its cooling ducts.

There are diagnostic tools available that let you know if the refrigerant needs a top up. However, the important thing to note is, refrigerants do not evaporate or run dry. So if there is a loss of refrigerant then it is probably because of a leakage.

Hvac systems are a necessity to keep the environment inside buildings healthy. These systems often face problems like pressure loss that need regular attention and can be avoided with monthly maintenance of these systems.
