What Does it Mean if Your AC Unit is Leaking Water?

Your HVAC system can produce a lot of water in a day...up to 20 gallons. Because of this, many of the service requests we receive at Ohio Heating & Air Conditioning are for AC repair due to leaking water caused by condensation. Leaks can occur if the condensate drain is blocked or clogged, the air filter is dirty, and or if there is a hole in the drain pan. 

The drain line of your air conditioner can fill with dust particles and bacteria. This can result in mold and mildew growingBryant AC 1109 in the condensation drain. Mold in the condensate drain system is especially dangerous.  A mold colony can disperse spores into the airflow in the supply ducts, and contaminate your entire home. People with allergies and other respiratory conditions are especially prone to suffer when this occurs. 

Over time the drain will become blocked. The result is flooding of the overflow pan and possible water damage inside your home. During the colder months when your  air conditioning system is not in use, especially for non-heat pump systems that perform cooling only, condensate and accumulated dust and debris that rests in the drain trap can convert to a dried blockage.

To help prevent the buildup and blockage of the condensate drain line, there are a few various methods of cleaning an air conditioner drain line. The two most popular methods are pouring white vinegar or chlorine bleach in the drain line to clear clogs. We don't recommend you pour chlorine bleach into a drain line. The strong vapors can cause premature oxidation and degrade your pipes.

Residential condensate drain lines are most often constructed of PVC. Chlorine bleach can quickly eat away at the PVC as well as the glue and cement that joins the line to the fittings and the condensate pan. Pouring bleach into a condensate drain will flush the drain pipe and its contents to the outside of the home. This can damage plants, lawns and anything it drips or spills on.

If the blockage does not clear after flushing with vinegar, a wet-vac or air compressor can be used to help clear the clog. Be extra careful. Damage can occur to your system if not carried out properly. Should you damage the PVC pipe, it could lead to water damage.

Flushing your system with vinegar or using an air compressor cannot solve the problem for every homeowner.  Air conditioning systems are not all installed the same way. Often gaining access to the condensate line can be very difficult and an experienced technician is needed. 

Preventing condensate blockage depends on how well your system is cared for and how often you replace the filter. Regular service and HVAC maintenance is always recommended every six months for optimal performance and to extend the life of your equipment. If you need help, give us a call.
