A sure sign is to check the supply registers. Is it warm? Open the panel and check for ice. However, seeing ice is pretty-well a guarantee that your AC is frozen. First, we must understand that temperature is how much energy a molecule has. The same works in reverse, cold air is comprised of low energy molecules. When it is compressed, the molecules get excited and heat up. The point of an air conditioner is to expand the refrigerant inside the evaporator coil so that it cools down, so when it leaves the air conditioner, it cools the air inside your home and effectively removes the hot air from inside the house.
However, if something in the air conditioner malfunctions, the whole system gets disrupted. This causes the evaporator coil to allow the refrigerant to cool too much, causing it to fall below freezing and ice over. So, how can you prevent something in the cooling equation from going terribly wrong? There are three main causes that lead to an AC freeze up.
By understanding these causes, you can get out in front of them so you never have to experience an AC freeze. Keeping your air conditioner in great shape will help it run more efficiently, saving you money on your energy bill, and keep it from becoming an eye sore. This restricts the air flow in your house. Keeping your AC clean and tuned up is also a good idea for preventing air flow problems, and other problems in general.
Your AC is already blocked, and you discovered that your air filters were clogged. They pull the water out of the air, which makes condensation that builds up on the coils. But if the drip pan is overflowing, the coils can become waterlogged and freeze. Dirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water fast enough.
Sometimes your blower fan can break, or become damaged during normal operation. When your blower fan is on the fritz, that significantly changes the airflow inside of your air handler. Too much condensation will build up on the coils, and the water droplets will not evaporate or drain properly. Without the hot air moving over the proper parts, a broken blower fan can also cause a refrigerant line to freeze too.
If your refrigerant line is frozen, be careful! The freeze can easily back up all the way to your condenser unit outside, causing problems. If you catch it in the early enough stages, you may be able to handle an AC freezing issue yourself. But if the freeze up is the result of dirty coils, or your system has water damage you can call us or schedule an appointment online.
Our team of experienced technicians provides quick, efficient repairs when your AC is frozen. Schedule Service Online Orlando or Tampa. A few different AC problems can cause your refrigerant temperatures to drop and freeze up the system, including:. If your air filter is clogged, it restricts air from passing over your evaporator coil part of the inside unit.
Start by replacing the clogged air filter with a new one. Then, turn off your system and allow it time to thaw out. Once it is thawed, run the system as usual. If there are additional problems, contact a professional to evaluate your AC system. Even a thin layer of dirt on the coil can cause it to freeze over. That layer of dirt can act as a barrier between the cold coil and warm unconditioned air from your home.
Have a professional clean your indoor coil. Your AC system cools by pulling in warm air from your home and stripping it of heat.
