What Causes the Evaporator Coil to Freeze?

One of the most common HVAC problems is the freezing of the AC evaporator coil. This problem will affect the normal operation of the AC. Fortunately, this is a relatively easy fix. The following is a brief description of the function of the evaporator coil, the reason why the evaporator coil freezes, and how to make the cooling system work again.

Over time, the evaporator coil of the system will be covered with dust, dirt, dirt, etc. This prevents it from getting the airflow needed to move the heat properly, which means the system may freeze later. For this exact reason, evaporator coil cleaning is an important part of our air conditioning service in Templestowe Lower.

If you manually close the floor or ceiling registers of many houses, the return airflow enters the coil. It may not get enough airflow to continue normal operation. Another common cause of this problem is that the homeowner unknowingly blocks the floor register under the furniture or carpet. Likewise, a very dirty air filter can block the main air source, preventing it from reaching the duct.

The refrigerant pipeline is a closed-loop system. However, in some cases, the refrigerant may be lost due to leakage or other problems. If there is not enough refrigerant, the molecules will expand too much. This will result in an uncontrolled cooling effect, which can cause the system to freeze.

Maintaining HVAC units over time through a preventive maintenance plan is more cost-effective than investing a lot of money. It can also ensure that you never lose a day’s business, nor stop working due to AC failures. This means you can relax and continue to do more important things, knowing that a reliable air conditioning service in Templestowe Lower is here for you.
