Central Air Condensate Drain

Central Air Condensate Drain

When installing a new air conditioner it is important to realize your new system will produce a lot of condensation that will need to be dealt with.



Humidity in the air is a major factor in how hot the inside of your home feels.  The job of your air conditioner is not only to produce cold air but also to remove moisture from the ambient air.  Think about a hot summer day when a parked car sits idling with the A/C on, there is usually a pool or stream of water that forms underneath.  This is the water that the cars air conditioner is removing before pumping it into the cabin.

The air conditioner in your home removes humidity in much the same way but the water can’t just be drained onto the ground.  The evaporator or A coil sits just above your furnace in the duct work.  To protect your furnace a drip tray or condensate pan is installed to dispose of the excess water.


Condensate Draining For Your AC

Since the central air condensate drip tray is directly below your evaporator coil the hundreds of water drips are all collected and usually removed via gravity though to a nearby drain. Sometimes there is no drain nearby and a small condensate pump needs to be installed. They are relatively cheap and easy to install.
There are some local codes here in Toronto and surrounding areas that stipulate the water can’t be drained into a plumbing vent or stack.  For the most part it is basically clean water and can be plumbed directly into the nearest drain with no need for buffers.


Common Central Air Condensate Issues

As mentioned, the condensate pan is located directly above your furnace and thus it is essential it works perfectly.  Should a problem arise water will spill over right onto the furnace heat exchanger which is a primary component that’s very susceptible to rusting.

Common problems could be that the drain line plugs or clogs causing the water to back up.  Also the drip pan can have debris that plugs the hole the drain hose or pipe is connected to.  Although a little more uncommon the drip pan can crack or tilt causing a leak as well.

Even though you can’t see the drip pan you can sometimes see signs that it is failing.  Water stains or rust on the top of your furnace is a good indication there’s a problem.

If you have a condensate pump you should try to do a visual inspection at least once a month during the cooling season.  They are a common fault area but relatively cheap and easy to replace if needed. Visually inspect the drain and the lines to make sure that the pump is the source of the problem.
