Why Did My Air Conditioner Freeze?

Have you noticed your air conditioner is not working efficiently as it used to? Maybe it’s blowing warm air? Can you see ice forming on the unit itself?

All of these could be the signs of a frozen air conditioner. Your unit is a complex machine, so there are a variety of reasons why you may be experiencing these issues. Some of the more common culprits that cause AC units to freeze are:

  • Leaking Refrigerant Lines. These lines deliver the chemical that produces and circulates the cold air in your air conditioner. When refrigerant is not contained or leaking in the unit, it could result in a frozen air conditioner. If you suspect you may be dealing with a leak of any kind, you should contact an AC professional right away.
  • Condensate Drain Not Working. The condensate drain is responsible for removing excess condensation and water in your unit. If the condensate drain is not properly evacuating, the trapped water can freeze and cause problems for your air conditioner.
  • Blocked Airways or Vents. Your ducts, airways, and vents are the systems that transport the air around your home. If they are prevented from adequately doing so, it could result in your air conditioner freezing.

Note that these are not the only things that may cause your AC unit to freeze. Again, if you’re unable to spot what’s causing the issue, you need to consult a professional HVAC technician.

How Do I Fix My Frozen Air Conditioner?

If your air conditioner is frozen, it’s important to first turn the unit off. You want to avoid running your air conditioner while it’s frozen because it wastes energy and could damage the unit. You could turn the blowers back on, as this could speed up the thawing process.

Do not attempt to remove the ice or buildup on the coils by hand. Damaged coils could also result in costly damage to your AC. While the coils are thawing, make sure you drain any water that may have been trapped in the unit using a shop vac.

After you’ve determined you’re dealing with a frozen air conditioner, you can take the right steps to correct the situation and prevent it from happening again. Perform these easy air conditioner maintenance tasks every three months for optimum performance.

  • Change the air filter. You need a clean air filter to allow warm air to circulate and keep the coils of the AC unit from freezing.
  • Clean the evaporator coils. Carefully use a brush to remove dirt or debris that has gathered on the evaporator coils. Do not touch the coil with your hand. This could damage the unit and result in a hefty repair bill.
  • Clear supply vents and registers. Make sure the airways are clean and allowing air to pass. Removing any obstruction or clogs will result in better airflow and prevent the unit from freezing.

When to Call a Professional for AC Repair in Somers Point

Some of the issues that lead to an air conditioner freezing can’t be resolved at home. If you’ve completed the steps above, and are still experiencing problems, it’s time to contact an HVAC professional.

A refrigerant leak or broken fan might be the culprit, at which point more advanced air conditioner repair is needed. Professional air conditioning repair companies have the knowledge and tools needed to get your air conditioner back up to speed!
