Lennox AC Frozen? Here’s How to Fix It

No matter where you live, the summer months can be brutal. Especially if you don’t have a working air conditioner. Many homeowners face AC break downs during the summer months. If you have a Lennox air conditioner and it’s frozen up, you need to know what to do.

Figuring Out if Your AC is Frozen

If your AC isn’t giving you cold enough air, then it might be frozen. There are several factors to identify if this is the case. Firstly, try resetting the circuit. If that doesn’t work, look at the bottom of the unit – there should be several copper pipes leading outside. If these are frosted or seem frozen, you know the unit is frozen up.

Causes of a Frozen AC Unit

There are several measures you can take to prevent your AC from freezing but it’s best to know what causes it in the first place. The most common cause of a frozen AC is a lack of air-flow. This is most often caused by a blocked filter, meaning that dust and dirt is clogging up the system and preventing enough air from going in. Another cause of a frozen AC is the wrong setting of fans in the unit. If the fan is set too low, the AC won’t circulate enough air, leading to a frozen unit.

Ways to Fix a Frozen AC

If you have a Lennox air conditioner that’s frozen, here are a few ways you can fix it. Firstly, clean or replace the filter. This may be enough to resolve the problem, though it’s best to always upgrade the filter in case it was too old or the wrong size. You should also check the fan settings and make sure that it’s set to medium. The fan should be heard, as an audible reminder that it’s working. If this doesn’t work, you may need to call a professional.

What a Professional Can Do

A professional can identify the root cause of why your AC is frozen and take steps to fix it. They may install a larger filter and make sure that the fan settings are correct. The technician may also check the coils, inspect the refrigerant levels, and replace any components that have failed, such as the blower motor or filter. This can help to prevent your system from becoming frozen again.


Having a frozen AC unit can be a nuisance in the middle of a hot summer. If you have a Lennox air conditioner and it’s frozen up, make sure to clean or replace the filter, check the fan settings, and consider calling a professional.

What are the Signs of a Frozen Air Conditioner?

An air conditioner that has frozen can be easily diagnosed. Look for signs of a frozen evaporator or condenser such as condensation, ice build-up and reduced airflow. Additionally, AC units also make loud noises, like a hissing or rattling sound, when they are frozen.

What Reasons Cause an AC Unit to Freeze Up?

The most common issue is a refrigerant leak. When there is not enough refrigerant, the system cannot effectively dissipate the heat and creates excessive amounts of moisture and condensation, which then freezes the evaporator or condenser coils. Dirty air filters, blocked air ducts, thermostat issues, and inadequate maintenance can all contribute to the unit freezing.

How is a Frozen AC Unit Fixed?

The first step is to shut off the unit and clean it of any snow or ice. Then, replace the air filters, check for and repair any refrigerant leaks, and lubricate any motorized parts as needed. Once these steps are complete, the system should be re-energized and checked for proper operation.

How Can I Keep My Lennox AC from Freezing?

Proper maintenance and frequent inspections are invaluable when it comes to preventing your Lennox AC unit from freezing. Be sure to replace filters regularly and keep the coils clean. Also, make sure the unit is adequately ventilated and inspect the lines, hoses, and seals.
