Do you know when to call a plumber for an air conditioner (HVAC) stoppage?

May is the perfect time to have your air conditioner and the condensation line checked before the Texas weather starts to heat up too much. It never fails, June arrives and the number of A/C stoppage calls that we get rises exponentially.  The AC system’s condensation line drains the moisture out of your home. If you don’t check the line regularly and clean it, it can wreak havoc – and usually on the first scorching day.HVAC Air Conditioner Drain

A clogged condensation line can cause your AC system to freeze. Even in the Texas heat.  A clogged drain will trap water in your AC unit and the evaporator coil will eventually turn to ice. The moisture in the drain line can also freeze, which will cause your air conditioner to turn off, AFTER it has caused damage.

A clogged drain line can cause the drain pan to overflow

To locate the A/C drain pan, look underneath your AC system’s evaporator coil – the indoor unit. After your air conditioner removes moisture from the air, it deposits it into the pan before draining it through the line. If the line clogs, the drain pan will overflow and cause issues with bacteria or mold growth.

An overflowing drain pan can damage drywall, cause significant leaks and destroy electrical wiring. It can cause extensive water damage, including mold. To prevent a clogged line, pour a cup of bleach into the opening of the drain line.

Trident Plumbing recommends that you check your drain line every month.


How to Check Your A/C Drains:

  1. Check for standing water in the drain pan
  2. Check tattle tail for dripping on the side of home (pipe by window)
  3. Check lavatory sink to see if full of water or slow draining
  4. Check to AC float switch
  5. Wet carpet in the hallway by AC closets
