Contractors are often asked: why does an air conditioner leak water? Air conditioner water leakage is one of the most common reasons for service calls. Small leaks may not seem significant, especially if your A/C stands outside. However, you should promptly investigate any unusual leaks. Check with a professional contractor if you consistently notice too much water drainage from your A/C.
All air conditioners produce water because they dehumidify the air. In the most humid weather, your A/C can produce as much as 48 ounces of water every hour. If the water doesn’t drain properly, serious damage to the A/C and your home could result if leaks go unchecked. If you notice more water than normal, check for some common problems: A blocked condensate drain line is most often the cause of A/C leaks. When this happens, water backs up into the drain pan. Use a shop vacuum to clear out the drain line and prevent future leaks. Newer A/Cs have an automatic shutoff which protects the A/C and your home from backed-up water. Sometimes the drain pan may be worn or broken. A professional contractor can replace it. Dirty filters are the next most common cause of a leaky air conditioner. They make the A/C starved for air and produce ice crystals on the coils. When the ice melts, there’s more water than normal. Always keep clean A/C filters handy. Faulty condensate pumps also can be a contributing factor to why does an air conditioner leak water. The pumps have a float switch that activates the pump when water rises in the drain pan. If it’s connected, test it by adding water to the condensate drain pan. It should automatically turn on. Why does an air conditioner leak water with improper A/C installations? Air conditioners that are not correctly leveled won’t allow water drainage to flow where it should. A/Cs that are not properly pressurized aren’t as efficient and collect more water than they drain.

The R-22 refrigerant phaseout could have an impact on your budget if your cooling system uses this refrigerant. Its use and production have both been scaled back per the conditions of the Montreal Protocol, which the U.S. signed. Scientists found that R-22 contributes to the depletion of the ozone layer and increases global warming. The protocol is global and participating countries must reduce the manufacture of this chemical, phasing it out altogether by 2020. Systems using R-22 are no longer manufactured after 2009, but pre-2010 systems still use R-22 for replenishment. Because the supply is restricted, the price has and will continue to climb, making this an expensive refill. Homeowners do have options, however, to deal with the R-22 refrigerant phaseout. The first is to keep the system components as clean as possible and the second is to replace older equipment that uses R-22 refrigerant. Any cooling system that's 10 years or older likely uses R-22.
Keeping the air filter clean inside the air handler reduces the likelihood of dust covering the evaporator coil inside. Dust and dirt contribute to small leaks in the coil, which can also contribute to leaking refrigerant. Hosing off the coils in the outdoor condenser will also prevent leaks from forming.
Most new cooling systems use R410-A as the refrigerant—a more efficient, less costly and safer product. The minimum energy efficiency of new air conditioners and heat pumps stands with a seasonal energy efficiency ratio (SEER) of 13, and if you're replacing one that has a 10 SEER or lower, your energy bills will drop substantially. New technologies for cooling systems provide more comfort and convenience, with better humidity removal and quieter operation.

Air conditioning is the single biggest energy consumer in your Virginia home this summer. If you’re shopping for a new A/C, you want to invest in one that will provide top features for comfort and energy efficiency. One of these features is a thermal expansion valve. Unlike fix orifices or capillary tubes, a thermal expansion valve changes its size to adjust the refrigerant flow rate based on current conditions. This precise method of cooling your home comes with several benefits:
In addition to a thermal expansion valve, your new air conditioner should also have the following features for the greatest efficiency possible:
