Why Your AC Freezes and How to Fix It

We’ve all been there—it’s the middle of a scorching Virginia summer, and your trusty AC unit suddenly sputters, blows lukewarm air, and, worst of all … there’s ice forming. AC units freeze up for a few reasons, and luckily, figuring out the problem means you’re closer to restoring that glorious cool air.

Airflow and Filtration

One of the primary reasons an air conditioner freezes up is due to a dirty air filter. Imagine trying to breathe with a cloth over your mouth. That’s how your AC feels with a clogged filter. This obstruction hinders proper airflow, leading to ice formation on the evaporator coils. A simple fix is to routinely check and replace your air filter every one to three months, ensuring your AC unit doesn’t freeze up and maintains good indoor air quality.

Faulty Fan

Another culprit for an AC unit freezing up is a faulty blower fan. This part of your AC is responsible for circulating air throughout your system. If it’s damaged or not functioning correctly, your unit won’t distribute air as it should, causing the coils to ice over. Regular maintenance checks are crucial to identify and rectify such issues before they escalate.

A Flow of Problems

Inadequate airflow itself can be a significant factor in why AC units freeze up. Damaged air ducts or other blockages can restrict the warm air from passing over the evaporator coils efficiently, leading to unwanted ice formation. You should have your ductwork inspected for any leaks or blockages that could be contributing to the problem.

Drainage Dilemmas

Lastly, a clogged condensate drain line can lead to AC freezing up. Besides cooling your home, your air conditioner dehumidifies it, too. The moisture removed from the air needs somewhere to go, and that’s where the condensate drain line comes in. If it’s blocked, water can back up and freeze on the coils, especially if they’re already too cold. Regular inspections and cleaning of the drain line can prevent this from becoming an issue.
