Something I have never seen before

Good day all:

I arrived at an inspection and the client met me in the driveway.

Q Hi Doug Have you ever seen a furnace mounted on top of a water heater?

A Nope

Q Well… you are about to.


This it it.

After thinking about it for a while I deduced the unit on top of the water heater was actually an air handler. Heated water from the tank flows through the handler and a fan blows air across a coil to heat the air to heat the home.

I suspect the air handler also contains an A/C coil as well. The client needs to shut the valve allowing hot water into the unit in summer so the A/C will function.

Am I correct?

I did advise him to get detailed instructions from the seller prior to close.

Thanks for any
