An easy way to tell if you have a high efficiency furnace is to look at.
Floor wet around furnace.
There s a 50 50 chance that it s something you can fix.
Here are four reasons why you might have a wet floor under your furnace and luckily two of them can be easily fixed without calling a repairman.
Again the most common reason for a leaking furnace is a condensation leak.
Common causes for water leaking around your furnace pvc drain line plugged.
When you see water puddling around the furnace with the a c running you have a clogged condensate drain tube.
But would it make that much water on the floor.

Sometimes the ac and the furnace share an internal drain and if there s something plugging up the drain which can happen if dirt and dust collect in there the condensation your hvac system produces inevitably overflows and leaks onto the floor under the furnace.
High efficiency furnaces extract heat from the combustion gases for a longer period of time than a standard efficiency furnace does causing the gases to cool then condense.
The coil is located above the furnace in that top part where the drain pipe comes out right.
Would the coils freeze if the temp was set too low.
With this restriction the water will push back into the coil and eventually spill onto the floor.
High efficiency furnaces those with an annual fuel utilization efficiency afue rating of 90 percent or higher have cool exhaust and as a result they produce condensation.
Route it to the floor drain and secure it with tubing straps.
The condensation is routed to a floor drain.
