3 Solutions To Try If Your AC Unit Freezes Up At Night | Blair's Air

Is your air conditioner freezing up on humid Florida nights? The heat and humidity in the Tampa Bay area during most of the year can put a strain on your AC, causing unexpected outages and even mold and mildew growth.

Don’t damage your air conditioner and live with malfunctions any longer. Blair’s Air is here to help you stay cool and comfortable. Below are some possible reasons why your AC is freezing up, and what you can do to address the issue.

Why AC Units Freeze Up?

The short answer is that whenever there’s blocked airflow through any of the air conditioner’s components, a portion of the AC will freeze. There are several things that could cause blocked airflow: dirty air filters, clogged condensate line, dirty coils, refrigerant leak, a faulty fan, among others.

The most simple step you can take to prevent this from happening is to change your air filters often and clean your condensate line (always make sure to turn off the power source to your AC before doing this).

Other than that, since there could be so many culprits, it’s crucial to have preventive AC maintenance on a regular basis. This can extend the lifespan of your air conditioner (saving you money in the long run) and prevent health hazards such as refrigerant poisoning due to a Freon leak.

AC Unit Freezing Up at Night? Try These 3 Solutions

1. Clean Your Evaporator Coils

Here are a few initial signs that indicate your AC evaporator coils have frozen up:

• Sudden decrease in AC performance
• Unusual amount of condensate drainage
• AC system running continuously
• Reduced airflow from vents
• Uncomfortably warm temperature indoors

Once you verify that your coils have frozen up, you’ll need to shut off power to your system (we recommend turning off the breaker in addition to turning off the thermostat) for several hours to let the ice thaw. If you’re short on time or on patience, you can speed up the process by using an air dryer in its lowest setting to melt the ice. Once the system has thawed, have a professional clean the coils. Dirty coils can not only freeze up and lead to breakdowns, but they can also cause mildew buildup. That’s why it’s important to address the situation right away.

2. Install a Humidistat in Your Home

A humidistat is a device that regulates the humidity inside your home. In a muggy climate like we have in Florida, we recommend installing a humidistat because if the humidity level inside your household goes above 60%, you could face the following issues:

• Windows and door frames can expand, causing air leaks
• Mold spores start growing in your home
• Book pages start turning yellow
• Bacteria that cause illnesses will have a perfect environment to grow
• Allergy and asthma sufferers may experience respiratory issues
• Your AC works overtime because it has to work longer to absorb all the moisture in the air
• This, in turn increases your energy bills and the amount of condensation in the coils
• Too much condensation that can’t drain results in a frozen air conditioner.

3. Schedule Preventive AC Maintenance

Scheduling a routine preventive maintenance inspection is the best thing homeowners can do to keep their HVAC system operating at peak performance and extend its lifespan. Schedule preventive maintenance and stop problems before they start.
