It has been widely speculated, but as yet unsubstantiated, that commercial ground-source heat pump systems have significantly lower service and maintenance costs than alternative HVAC systems. This paper describes efforts recently undertaken to survey commercial buildings with ground-source systems. Data from 25 such systems are presented here including total maintenance costs in dollars per hundred square feet per year both for in-house and for contractor provided maintenance. The total maintenance costs for this sample were shown statistically to be significantly lower than those reported for conventional systems in the 1995 ASHRAE Handbook- Applications. The mean annual total maintenance costs for the most recent year of the survey ranged from $7.32/100 ft2 to $10.95/100 ft2 for in-house labor and contractor provided maintenance, respectively.
