Hello, low pressure *differential in the ground loop, (measured between the water in and water out connection on the water furnace can cause poor performance.. If the differential pressure was 10 lbs then thats fine, if the pressure measured at just one connection was 10 lbs then thats low.

Dirty air filters will also cause poor performance, so can the incorrect ounces of refrigerant cause poor performance.

.

the water furnace should be good for 15 to 20 years or a bit longer, so far it sounds like were talking to person on a sales commission.
