What is causing your AC System to Leak Water?Why does water sometimes leak from air conditioning systems? This is a question many homeowners have asked themselves because it is a very common problem. It’s actually one of the most common reasons homeowners need urgent repairs. Having water leak into your walls or ceiling can be a scary experience and it’s an issue that needs to be fixed quickly.Fortunately, repairing water leakage isn’t too hard for a trained technician. Learn what the common causes of AC water leakage are and what most likely needs to be done to repair the system below.Clogged or Disconnected Drain LineA clogged condensate drainpipe can make your AC system’s drain pan overflow. This is probably the most frequent cause of water leakage from a central AC system, especially as summer temperatures rise. The clog can be caused by debris like dirt, rust or algae.The drainpipe could also be disconnected. If an AC system is improperly installed, drainpipe fittings may not be secure.

Over time the pipe can loosen and eventually disconnect from the AC unit, allowing the condensate to drain through the ceiling, walls or onto the floor.Drain Pan Position or CracksThe evaporator coil inside your AC system collects condensation from the cooling process. As warm and humid air passes through, the inside coil loses some of its moisture. This moisture then drips into a drain pan that has to be angled correctly so water can drain properly. carrier heating and cooling wall unitIt’s similar to why bathtubs are positioned at a slope so all the water can fall into the drain. parts of split type air-conditioning unitIf this is the case, a technician may only need to reposition the drain pan to create a more efficient slope.central ac unit install

In some cases, however, the pan may require replacement. Cracks can form in it over time, which leads to leakage.Other potential causes of AC water leakage include: – Condensate pump problems – Clogged air filter – Condensate buildup in un-insulated ductwork – Low refrigerantHow to Avoid Water Leakage DamageThese tips will reduce the likelihood of AC water leakage: – Make sure your central AC system has a secondary drain line – Install a drain pan overflow shut off switch – Clean or change your HVAC air filter regularly – Make sure ductwork is properly insulated – Have your AC refrigerant levels checked regularly – Keep your condensate pump free from mold and mildew by flushing it with a 50% bleach/water solution – Schedule annual HVAC maintenance to minimize AC repairsCall WG Speeks Heating and Air Conditioning Experts for Quality Air Conditioner ServiceIf you experience water leakage or other AC issues, such as Air Duct Cleaning and HVAC Repair and Installation, call us at 804.276.2800 804-276-2800 and see why W.G.

The two possible causes are 1) actual leak of rainwater from the outside or 2) condensation, which is a normal byproduct of the air conditioning process but should be dripping outside your home, not into your wall! Since the amount of condensation increases as the relative humidity outside increases, you are correct to wonder whether there is a connection between the humidity and the You can locate the source of a rain leak by making a visual examination of any weatherstripping or caulking around the outside of the machine itself, or the sleeve that the "works" of the AC slides into. If you find any gaps or openings in the caulk, you can scrape out the old caulk and replace it. If there is a rain gutter over the AC unit, make sure that it is not blocked. If the gutter were to overflow you could get leakage around the AC or through

the air vents in the frame even if the caulking seems OK due to the sheer volume As I mentioned, the condensate from the AC normally flows to the outside and exits the frame via weep holes in the frame (or pan). rubber plugs underneath the pan, designed to allow condensate flow.  have accessory kits that allow you to install a hose to redirect this condensate in dripping straight downward is not acceptable. If the condensate exit holes are blocked, water can build up in the bottom of the pan and potentially leak out where it shouldn't! You will have to examine your unit to see where these weep holes are and if they are blocked. culprits are rust or paint chips that drop into the pan and block the weepThis could also account for the sudden dripping! AC units that slide into a preinstalled through-the-wall sleeve are oftenThe body (and tray) must be installed at a slight downward angle towards the outside. Were the unit to somehow change level, it is possible

that the condensate would instead build up in the bottom of the frame and leakThe only way to know for sure is to put a level on the frame to see if it is level. If shifting has occurred you will need to modify the mounting (either inside or outside) to restore the downward tilt. To your other issue, the loss of cooling power is definitely attributable at least in part to the increased humidity. Some of the cooling energy is being used up drying up the moist air in your home. Dust on the cooling coils would also cause loss of cooling power, and would worsen with increased humidity as the dust holds the moisture, producing a damp insulating blanket on the coils. Finally, mechanical problems with the coolant pump and/or a loss of coolant pressure are other possible causes that should be investigated. Return to NH's Question and Answer Index Water Dripping From RV Roof AC Question: We recently purchased an older 5th Wheel. When the AC was turned one the first time, the AC works fine, but water was dripping down the outside of the camper.

Any suggestions to solve this problem would be greatly appreciated. We are an older couple and are anxious to get moving with this unit. Robbie: Water running down the side of your unit from the AC is a good thing. Just like water dripping out from under your car when you use the dash AC. There is a hole in the AC allowing the water to run onto your roof and you seeing this water tells you the AC is working fine. When a customer calls me saying they are having a problem with there AC cooling, one of the first questions I ask is "Do you have water running down the side of the coach".
