We often take our home appliance for granted, never giving them a second thought so long as they work they way they’re supposed to when we need them. However, as soon as one of these appliances malfunctions, we’re given a stark reminder of just how much we rely on them each and every day. This is especially true in regard to the HVAC system, which works to create a comfortable environment throughout the home. So if you find that your air conditioner’s indoor unit is leaking water, there could several reasons why. Below you’ll find some information concerning the most common reasons your air conditioning unit could be leaking and the HVAC maintenance needed to fix them.

Broken Condensate Pump – If your condensate pump has broken, it’ll be unable to expel excess water properly, causing the water to gather and then leak from the unit itself. To check as to whether or not you have a broken condensate pump, pour water into the condenser pan to see if it pumps out the excess water. If it doesn’t, it may be time to have an HVAC professional examine the pump and suggest options for repair or replacement.

Poor Installation – PVC fittings that were improperly cemented can cause the drain pipe to disconnect from the ACE unit and condensate to drain through the ceiling and onto the floor. If you find that the drain is secure, then the leak is more likely being caused elsewhere in the unit.

Pressure Overload – A closed or backed up vent can increase the pressure in your AC unit’s valves, causing them to leak water. If you find that water is leaking, have your vents inspected to ensure that they aren’t closed or blocked.

Clogged Drain Hole – As dirt and debris travel through your drain line, they can gather and become stuck, clogging it and causing water to back up in your drain pan and overflow. The best way to deal with a drain line blockage is to have an HVAC professional vacuum it out.

Loose Seals – Air conditioner seals that are loose will allow warm air to flow into your air unit. The warm air then forms pools of water when it condenses with the cold air inside the unit. If you find that this is the case with your unit, consult a professional to examine your system. An HVAC professional can help to reseal your unit, thus protecting it from the outside air.

Dry Air Filter – When air is unable to move freely through your filter, condensation can freeze around the evaporator coil and spill out of the condensation pan. This is one of the reasons why you should change your filter regularly, as it allows the air conditioner to run more smoothly and more efficiently.

Low Refrigerant – Low refrigerant can cause the pressure in your AC system to lower over time, causing the evaporator coil to freeze over. When the unit shuts off and the coil begins to melt, water starts to drip on to the floor. Scheduling regular tune-ups for preventive maintenance can help to regulate refrigerant levels.

Almost all of the issues surrounded leaking air conditioner units can be prevented with regular maintenance, so its best to schedule your HVAC service sooner than later.
