This may seem like an oxymoron – a frozen air conditioner unit in the midst of summer – but it is actually a very common problem for homeowners. Our team at Action Air Conditioning knows how quickly a frozen AC system can make a nice summer day go awry, so here is all the information you need to prevent, troubleshoot, and repair a frozen air conditioner.
How do I know if my Air Conditioner is frozen?”
The first sign is leaking water around vents or the Air Conditioning unit. Check the registers inside your home while the AC is on. If the vents are blowing out warm air, it could very well be a frozen Air Conditioner. Locate the evaporator coil on your HVAC (typically near the furnace system inside the home) and open the access panel. Small hex-head screws should be holding the panel in place. You will be able to see the ice formed around the coil, or even outside the Air Conditioning unit in severe cases.
What should I do when I notice my Air Conditioner is frozen?”
Turn off your Air Conditioning completely and call a licensed HVAC contractor. This will allow the unit to de-thaw until an HVAC technician comes to the rescue. Don’t try to scrape off the ice by hand as this could cause even more damage to the Air Conditioning unit resulting in an expensive repair. Also check to see if the air filter is dirty as it could be the culprit to your frozen Air Conditioning. Even if the air filter is dirty and replaced, you should still get a licensed HVAC contractor to examine the unit for any other issues that contributed or caused the problem.near the furnace system inside the home) and open the access panel.

What causes a frozen Air Conditioner?
There are two main causes of a frozen Air Conditioner: restricted air flow or a lack of refrigerant. Without proper airflow to the evaporator coil, the condensation will freeze before it gets a chance to be drained from the unit. Restricted air flow could be caused by a dirty air filter, faulty fan, closed registers, or drainage issues. Refrigerant is necessary to prevent the evaporator coil from freezing. If the refrigerant is low, it could be the source of the problem and would require a licensed HVAC technician.
What can I do to prevent my Air Conditioner from freezing?
Performing regular maintenance on your HVAC is the best way to prevent AC malfunction and expensive repairs. We recommend an AC Tune Up twice a year for newer models, or 4 times a year for older HVAC systems.
Keep up with your air filter. A dirty air filter can not only cause a frozen AC, but poor indoor air quality, expensive utility bills, and put unnecessary wear and tear on your HVAC system.
