Tips to Prevent Lennox AC Freezing Up Issues

If you live in San Diego, you know the importance of keeping your home cool during the hot summer months. Your Lennox AC system is a critical part of keeping your home comfortable, but what do you do when it freezes up? We’ve put together a list of preventive measures recommended by manufacturers and HVAC technicians to keep your Lennox AC running smoothly.

Change Your Filter Regularly

The most basic way to prevent Lennox AC Freezing Up issues is to change your air filter regularly. A dirty or clogged filter restricts airflow, causing the evaporator coil to freeze up. Lennox recommends replacing your air filter every three months and more frequently if you have pets or allergies.

Check the Refrigerant Levels

If your Lennox AC’s refrigerant levels are low or imbalanced, it can cause the evaporator coil to freeze up. HVAC technicians recommend having your refrigerant levels checked annually to ensure your AC system is functioning correctly. If your refrigerant levels are low, your technician can add more refrigerant to your system.

Inspect the Evaporator Coil

Over time, the evaporator coil in your Lennox AC can become dirty, causing it to freeze up. HVAC technicians recommend having your evaporator coil inspected and cleaned annually to keep it running smoothly.

Keep Your Thermostat Consistent

If you’re constantly adjusting the temperature on your thermostat, it can cause your Lennox AC system to freeze up. Manufacturers recommend keeping the temperature consistent throughout the day rather than frequently adjusting. You can also invest in a smart thermostat that adjusts the temperature automatically based on your preferences and schedule.

Schedule Regular AC Maintenance

Prevention is always better than cure when it comes to your Lennox AC system. HVAC technicians recommend scheduling regular maintenance checks twice a year, in the spring before the hot summer months and in the fall before the cold winter months. During these maintenance checks, your technician can inspect, clean, and repair any issues before they turn into significant problems.
