Why is my furnace ….?
People have lots of questions about their furnace. Here are a few answers to the most common questions:
- Why is my furnace leaking water? There are a few reasons that this could be happening. If you have a high-efficiency furnace, the most common reason is a condensation leak. The condensation normally exits through a drain. If you have water that is pooling around the furnace, there is probably something preventing to water from draining properly.
- How do you know if you have a high-efficiency furnace you ask? The quickest way to tell is if the yellow energy guide tag says your furnace’s efficiency is 90% or higher AFUE (Annual Fuel Utilization Efficiency). You can also look at the vent/flue pipe. If it’s white PVC instead of metal, you probably have a high-efficiency unit.
- Why is my furnace shutting off too soon? Winter is rapidly approaching and not having a working furnace is a BIG problem. Dirty filters are the most common problem with furnaces. The dirt and dust clog the filters which reduces proper air flow. This can cause your furnace to work harder that it needs to which can cause the heat exchanger to overheat and shut your furnace off too quickly without properly warming your home. As we mentioned last week changing your filter monthly is a great practice to start.
- Why is my filter wet? So, a month has gone by and you go to change your filter and it’s wet. What on earth could be causing this? The reason goes back to our first question about your furnace leaking water. Your filter could be wet because the condensation isn’t able drain properly due to a blocked or damaged drain or condensate pan.
