We have an Intertherm furnace in our manufactured home which is apparently a replacement furnace as this is not the brand showing on the original paperwork for the home. Problem is that it is very loud. When it's running either for heating or the A/C we have to talk loud to hear each other and have to turn the volume up on the TV or radio. Is this normal or is there an adjustment that should be made?

OK. Let me answer you, even if honestly I don't have any idea about an INTERTHERM FORCED AIR FURNACE. To get any answer, to a problem, you should describe your problem. Just telling that you don't know what's wrong with it is simply no enough information, even for a star expert in your INTERTHERM FORCED AIR FURNACE.

Power off, power on. Let know what happens

either the heat strips, fusible links on elements or sequencers.
