It is important to note that low refrigerant levels is not the only cause of frozen AC pipes, but it is one of the most common. It is highly recommended that you contact a professional HVAC technician to inspect and repair your unit if you suspect low refrigerant levels may be the culprit. By doing so, you can ensure that your AC unit operates efficiently and effectively, providing you with cool and comfortable air when you need it most.

Dirty Air Filters

Dirty air filters are one of the common culprits behind frozen AC pipes. When air filters become clogged with dirt, dust, and other debris, the air flow to the evaporator coil is reduced, causing it to freeze. As a result, the condensate that comes from the evaporator coil is no longer able to flow properly through the pipes, eventually leading to frozen pipes.

This is because the frozen coil acts as a barrier to the flow of refrigerant, causing it to accumulate and freeze solid. Keeping your air filters clean is crucial to preventing frozen AC pipes. It is recommended to replace your air filters every 3 months or more often if you have pets or allergies.

Remember, a little maintenance goes a long way in keeping your AC system running smoothly and avoiding costly repairs.
