Furnace Condensate Drain Pipe Freezing

A furnace produces condensate as it works it s part of the combustion process and this condensate must be drained and removed to the outside.

Furnace condensate drain pipe freezing.

When you see water puddling around the furnace with the a c running you have a clogged condensate drain tube. With temperatures dropping condensate drain lines have a higher chance of freezing. This will kill any algae mold or mildew that has formed in the pipe. You can prevent slime and eliminate drain tube clogs in two easy steps.

Condensation from air conditioning coils contains bacteria that can form slime and clog the condensate pan drain tube. Just pour a cup of bleach in the drain line s access opening near the indoor air conditioning unit. As an emergency only i split the pvc right out of the bottom of the furnace then attached control valve and a screw on hose attachment. If the pipe that runs the condensate to the outside of the house freezes over your furnace won t be able to work.

With the pipes blocked the condensate backed up into the furnaces where safety switches shut the units down. If the condensate drain line is clogged you will need to use a wet dry vacuum or a special pump to unclog the line. We re here to handle all of your hvac issues so you can snuggle up through the cold weather.

Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks. In reality a major repair may not be necessary as thawing the frozen drain lines should fix the issue.

If you have a frozen condensate line your furnace will eventually be unable to function and your house will be freezing.
