How Does An Air Conditioning Unit Work?

How you probably imagine an AC works is wrong. Contrary to popular belief, an AC system does not inject cool air into a building. Instead, it removes the heat from inside and transfers it outside. Cool huh? (Pun intended).There are 4 major components among the 3 stations of an air conditioning system: the evaporator coil, the compressor, the condenser, and the refrigerant – a special chemical that links everything together through a closed loop system.

Station 1:

Warm indoor air is sucked into the return vent, through a filter, and blows over the evaporator coil. The heat is absorbed into the cold refrigerant, turning it from liquid to gas. The air, which is now cool, is blown back into the home to areas that your thermostat, i.e. you, has decided.

Station 2:

The refrigerant makes its way outside the house to the compressor, which squeezes the warm refrigerant, raising its gaseous temperature even more.

Station 3:

When the super hot vapor refrigerant reaches the condenser, the last step, the heat is expelled and absorbed into the outdoor air. The refrigerant instantly cools, which changes it from gas back to liquid form. The cold liquid refrigerant is now ready to return to station 1 and repeat the process.

Is Your AC Freezing Up? Here Are The Signs:

As you may have guessed, your air conditioner unit freezing up on a hot day is not normal.

If this happens, there's no need to panic. Often the issue can be solved with a little troubleshooting. If the AC unit is left frozen for too long however, you may find yourself with a bigger problem.

First things first, how do you know your AC is frozen?

Well, the obvious sign is the ice on your refrigerant line-set pipe. Simply check between your outdoor AC unit and your home's exterior wall to see whether your AC line frozen.

You might also have a frozen evaporator coil. This one's not as easy to check. You'll need to open a panel on the indoor unit to inspect. Don't do this unless you're handy. If you aren't, call an HVAC pro like SuperTech HVAC or you may damage something in the process.
