If you notice that your central air conditioner starts making funny noises, you should go outside and see what the condenser box is doing. If it is spitting fluid with each spin of the internal fan, back away and call an air conditioning repair service. You do not know what the fluid is, and it could hurt you. Here is why your "spitting" air conditioner is a problem.
There Could Be a Major Refrigerant Leak
The fluid spitting out of the condenser box could be refrigerant. This substance can cause cold burns on your skin and make you go blind if it lands in your eyes. Stay away, and keep children and pets out of the area until a repair technician can examine things. It is also a good idea to shut off the air conditioning to minimize poisoning the environment if it is a refrigerant leak.
Rain Water May Be Flooding the System
While most air conditioners are air-tight systems that remain unaffected by rainwater, it does not mean that they cannot be flooded. If there is the smallest hole in a component high up in the condenser or low to the ground, rainwater can get into the air conditioner. The appliance may then try to expel the water because the water does not belong. Since these machines are not built to do that, the water spins about and spits out. (Most of the danger here is related to water and electrical components, so steer clear.) The repair technician has to find the hole and either patch it or replace the part to restore proper function to your A/C.
Part of the System May Be Frozen
When parts go bad, the A/C unit can lock up or not drain properly. Additional condensation cannot make it through the system and spits out via the fans inside. The repair technician will need you to turn off the A/C unit, let it thaw out, and then find out why it is freezing up. From there, the technician can repair the problem or inform you that you need an entirely new central air unit. Until you know what the dangers are, you do not want to touch any part of a frozen air conditioner.
Checking the Drains and the Plumbing
A plumber may come to check out the problem with a spitting A/C unit. Because the problem could be blocked drains, the plumber can unblock the drains to see if that stops the appliance from spitting. If the problem continues, you may have to explore one or more of the above issues to see what the real problem is.
