What Causes my HVAC System to Freeze?
At Rudd Heating and Air, we understand that here in the south, having an HVAC unit that runs smoothly is incredibly imperative. There are many reasons why your HVAC system is giving you trouble. HVAC systems sometimes freeze themselves, creating problems for the homeowner. The following are a few reasons why your HVAC unit may be freezing:
As you can imagine your HVAC system needs proper airflow to work. The first thing you can do in order to check the airflow is to make sure that your filters are clean. The next is to check all of the vents in your home and ensure air is flowing freely through the vents. Don’t block or close any vents as that can cause air restriction to the unit.
The refrigerant used in HVAC units changes its physical properties due to pressure change. This pressure change causes the refrigerant to act differently and therefore, no longer perform effectively. The change in the refrigerant pressure can cause your AC components to freeze up.
Failed Blower Fan
A blower fan on an AC unit helps move the cool air throughout the home and push the warm air back outside. In order for the blower fan to work effectively, there needs to be a balance of airflow in air pressure. If your blower fan is damaged it can also cause the line to freeze.
It is imperative to keep your HVAC system as clean as possible. We have talked about in past blogs of proper maintenance for your HVAC system. If the coils within your HVAC system are dirty it can cause the water pulled from the air to condense and freeze onto the coils themselves or pipes within the HVAC system. Signing up for by annual maintenance can prevent this.
At Rudd Heating and Air, we can take care of all of your HVAC needs in order to prevent your system from freezing. If you have any other questions or concerns please contact Rudd during the week.
