Not many homeowners are equipped with the knowledge and understanding about air conditioners to prevent this problem on their own. It’s a problem that can turn a beautiful summer day into a blistering hot one in minutes.
What should I do if my AC unit is frozen?
In many cases, you may be able to defrost the ac unit yourself. You should avoid running the air conditioner if you think you have a frozen evaporator coil because this can place a strain on the compressor which could possibly cause damage and burn it out.

What happens to the air in an AC when it is not compressed?
So, what the Joule-Thomson Effect demonstrates in thermodynamics is when the air in our ACs isn’t compressed, its temperature will decrease as it expands and the molecules slow. When it is compressed, the molecules get excited and heat up.
Why does my a / C not work when it’s Hot?
A/C only blows cold air below 78 degrees or so. Above that, it only blows out hot air. That is not normal, you may need to get the A/C looked at by an authorized dealer. Mine blows very cold, no matter how hot outside it is.
What causes an outside a / C unit to freeze up?
A faulty contactor in outside unit will cause freeze up because the outdoor unit keeps running when it should be off. The contactor’s purpose is to send electricity to the outside A/C unit. As your thermostat calls for cooling, the contactor moves to connect to your A/C to electricity.
What to do when your air conditioner freezes up?
A dirty cooling coil is one of the most likely reasons and a/c is freezing. Shut off the A/C off at the thermostat. Speed up the ice melting process by turning on the furnace fan with A/C turned off.
