For us Southern Techs


In Florida there are not many gas furnaces. At least not as many as up North.

So, sometimes we can look like real dummies compared to techs who work on them everyday.

One thing to know about furnaces with case evaporator coils is that you can check the evaporator coil by removing the high limit and running an inspection camera up through the opening. 

You may also be able to use a mirror and flashlight but you usually won’t see much due to the heat exchanger being in the way.

Otherwise you are stuck removing the entire blower assembly… and that’s no fun.

    Just make sure to turn off the power before removing limit switch. Or it’s like playing operation pulling it out without shorting against the sheet metal.
