Why is my AC freezing up in Columbus OH?

AC units freeze up due to restricted airflow (clogged filter or blocked vents), low refrigerant, or a dirty evaporator coil. Turn off the AC and let it thaw, then call (614) 368-0104 for same-day diagnosis in Columbus.

What should I do if my AC is frozen?

Turn off the AC immediately — running it while frozen can damage the compressor. Switch the fan to 'on' to help it thaw, and put towels around the indoor unit to catch water. Once thawed (2-4 hours), check your filter. Then call us to diagnose the root cause.

How much does it cost to fix a frozen AC in Columbus?

Cost depends on the cause. Filter replacement is inexpensive. Refrigerant recharge runs $200-$350. Coil cleaning is $150-$300. We provide upfront written estimates before starting any work.

AC Freezing Up Columbus OH | Frozen AC Fix

Finding ice on your air conditioner is always alarming — especially on a hot Columbus summer day when you need your AC most. The irony is that a frozen AC actually produces less cooling or none at all, and running it while frozen can permanently damage the compressor. Here's what to do and why it happens.

🛑 Do this right now if your AC is frozen: Turn the system OFF at the thermostat. Switch the fan to ON (not AUTO) to help thaw it. Place towels around the indoor unit to catch drip water. Do NOT run the AC until it's fully thawed and the cause is diagnosed — call (614) 368-0104 for same-day service.

Why Is My AC Freezing Up?

Dirty or Clogged Air Filter

The #1 cause of frozen AC in Columbus homes. A severely clogged filter restricts airflow across the evaporator coil, causing it to get too cold and freeze. Check and replace your filter first — it costs $10 and takes 5 minutes.

Low Refrigerant (Freon Leak)

When refrigerant level drops due to a leak, the pressure in the system drops, causing the evaporator coil to get abnormally cold and freeze. This requires a professional to find and repair the leak, then recharge the system.

Dirty Evaporator Coil

A layer of dust and dirt on the evaporator coil acts as insulation, preventing proper heat transfer. The coil gets too cold and freezes. Professional coil cleaning restores normal operation.

Blocked or Closed Vents

Closing vents in unused rooms or blocking vents with furniture reduces system airflow, causing the same freezing effect as a dirty filter. Make sure all supply and return vents are open and unobstructed.

Failing Blower Motor

If the blower motor is failing or running at reduced speed, it can't move enough air across the coil, leading to freezing. This requires professional diagnosis and motor repair or replacement.
