What makes an air conditioner freeze up

Have you observed that your air conditioner freezes up sometime after you switch it on?

Especially on a hot summer day, it can be a bit irritating that it acts up when it works every time.

This happens because the air ventilation gets clogged by an ice. When it gets clogged its usually because there is no proper released of cool air and blocks of ice built up on the evaporator coil.

For an air conditioner to work properly, it needs proper air ow from the room and vice versa. It should suck up the heat in the room to be replaced by a cool air. So what makes an air conditioner freeze up? here are the possible reasons and what you can do about it:

Restricted Air ow

A proper air ow is needed to keep the cold coil warm. If the warm air from the room into the unit and vice versa, can’t circulate properly its most likely that the cool air will just stay in the evaporator coil resulting in the drop of temperature. And more ice will be formed, blocking the air.

That’s why it’s always good to check and change, only if needed, your air lters.

You can take them down and wash with water and soap at least once or twice a month. Dirty air lters can block air ow so make sure that it is clean, clear and open.

Also, dirty air lters can make the evaporator coil clogged up due to dirt. If you’re not sure how to clean them, it’s best to call a technician.

Damage Fan or Blower

If you have already checked the air lter and the evaporator coil and both are working ne, the problem might be the fan is broken.

The fan helps to take the hot air from your home and replaced it with cold air, blowing it where it needs to go.

If it gets damaged, it changes the air ow. There are also times when there is no air coming out of the AC, the fan motor may have burnt or its loose. If that is the case, call a technician.

Low Refrigerant

A refrigerant is a chemical that is responsible for the heat exchange so when it is low, your AC won’t be able to absorb enough heat.

A leak is the reason why the AC is low on refrigerant. You might see some signs like frozen evaporator coil, a broken compressor, drop in cooling ability and much more. If this occurs, call a technician because they are the only ones who are allowed to recharge an AC. They know how much refrigerant to put back and restore the lost refrigerant in the system.

To Summarize

Every household face air condition problem and it’s common for it to freeze up.  If you see some signs that something might be broken or loose on the inside, go and x it.

If you already know that it is broken and still keep on using it serious problems might arise.

You can prevent these problems by having a regular check up on your AC and will keep it from running better.
