Is Your AC Unit Freezing/Frosting up?
Cold air conditioners are fantastic, but frozen air conditioners would be just the opposite. When your air conditioner is freezing up, it can’t properly cool your space. And worse, if you don’t do something about it quickly, you can end up with water damage in your walls and ceilings as well as an expensive AC repair on your hands. That doesn’t seem like the good day people are hoping to have.
There are a number of reasons for an AC unit freezing up, but the most common are:
- diminished airflow (clogged filter or broken fan)
- a clogged drain line
- a refrigerant leak
- a faulty thermostat
Most of these causes of an AC unit freezing up can typically be fixed real quick and easy if caught sooner than later. However, if you ignore an air conditioner that’s freezing up for too long, the strain on the system can lead to compressor failure. That’s a very steep repair cost at best, and may end up resulting to having to replace the whole system.
Don’t Know What to do?
If you notice that your air conditioner is not cooling like it used to, and you take a look at the indoor unit and see ice or frost on the coils, the first thing you must do immediately is TURN THE UNIT OFF. Don’t just turn up the thermostat temperature setting; set it to OFF. Technicians are unable to work on your unit if it’s frozen solid.
How to unfreeze your AC unit safely
If there is a abundance amount of ice on the coils, you might not want to wait for your AC service technician to remove the ice. Depending on where your unit is located, the melting ice can drip causing water damage to your floors, walls and ceilings.
If you are worried that this might happen, you need to know how to safely remove the ice without causing further harm to the equipment. IMPORTANT: Never use a sharp object to try to chip away the ice, which can cause damage to your air conditioner’s sensitive coil fins!
Try these techniques instead:
- Try turning on the system fan (turn the thermostat to the FAN setting so the AC is not running) to melt the ice. This may take a few hours. IMPORTANT: Don’t try to do this if there is ice on the fan!
- If the fan is not working (or you want to melt the ice faster), you can try using a blow dryer to melt the ice.
- If it looks like the melting condensate is dripping outside the drain pan (or even into the ducts), use a wet vac to clean up the water. The last thing you want is water in the ducts that can lead to mold growth.
While you’re at it, you might want to check the condition of your air filter. If it’s completely clogged, that might be why your air conditioner is freezing up. To function properly, your AC needs warm air flowing over the coils. A clogged filter reduces the air flow, and can result in the AC unit freezing up. Changing out the filter might be all you need to do to solve your problem.
If it’s not the air filter, though, it’s time to call R.A STYRON to get to the bottom of your AC unit freezing up.
We Can Certainly Help!
At this point, your air conditioning problem must be diagnosed by a professional. If you didn’t find a clogged filter, never melt the ice and turn the unit back on without an inspection! If you do, that is risking bigger problems such as system failures and a new replacement in the future. Not cheap fixes that is for sure.
