What can cause condensation in an AC unit?

Condensate Pump Issues A faulty or unclean condensate pump can also cause water leaking from your air conditioning system, flooding your attic or basement. Mold and mildew can form within the unit due to the constant presence of water, causing it to clog. This needs to be repaired by a professional.

Leaking Refrigerant Lines Leaking refrigerant lines can occur when there is damage to the insulation around them or if the tube itself has been corroded by moisture. Leaks can also occur if the line is being used for a non-refrigerant fluid. Corrosion from liquid oil or other chemicals may also cause refrigerant lines to leak. This problem needs to be diagnosed by a professional who can provide appropriate repairs.

Freezing Up Evaporator Coil Your evaporator coil may freeze up if you live in a cold climate and don't use your air conditioner for several hours at a time. Make sure that the drain valve on the back of your unit is closed before you turn off your system.

Overloaded Circuit Breaker An overloaded circuit breaker means that someone has opened too many circuits at once. Call an electrician immediately to correct this problem.

What causes an AC unit to leak water?

Water leaks can be caused by a variety of factors, including: Problems with Condensate Pumps: If your condensate pump is unclean or malfunctioning in some manner, it might cause a water leak in your AC unit and perhaps flood the area where this section of the unit is located. This could also be caused by a bad power switch or wiring on the unit itself. Check these areas carefully for damage when performing maintenance on your air conditioner.

If your compressor is leaking lubricant, there will be a loss of oil that must be made up with additional lubrication. This leads to increased wear and tear on other parts of the system, which will need repair or replacement sooner rather than later. A leaky compressor should never be used again after it has leaked lubricant; instead, it should be taken to an authorized compressor manufacturer for repair or replacement.

A damaged fan belt may seem like a minor issue, but if it's not replaced promptly, it could lead to more serious problems down the road. A faulty belt could indicate that one or more of your components (such as your compressor, pulleys, or fans) are in need of replacement. A loose belt could also prevent proper rotation of your compressor's motor, which could cause damage to other parts of your system. Be sure to check all belt loops and tighten any that appear loose or broken.

Why is my AC unit leaking into the pan?

A blocked drainpipe is the most common cause of an air conditioner's drain pan being full with water. Algae, mold, and other microorganisms thrive in the refrigerant coils and pipelines. Algae and mildew can clog the drainpipe over time, causing water to accumulate and spill into the drain pan. Blockages can also form if you use non-permanent solutions like baking soda or sand to unclog your drains. These items will eventually fill up with debris and need to be removed for proper drainage.

If you check all the usual spots for leaks - around the valve, inside the casing, etc.- you won't find any. This means that something is leaking into the pan from somewhere else on the system. Usually this is the compressor discharge line, but it could be another part of the system such as the heat exchanger or the expansion valve. Leaking components require replacement; old rubber hoses can break down and leak fluid. Inspect the system carefully for damage when you get back home from vacation; if you find anything out of place, have a repair person take a look at it.

The first thing to do is turn off the power to the unit. If it is still under warranty, have the manufacturer address the problem. Otherwise, call a professional HVAC company as soon as possible. They should be able to provide you with a quote to fix the problem and install new components if necessary.
