Company System Analysis and Cost Comparison Report
 This
report is based on a system analysis and cost comparison report
on an existing 7 SEER 5 ton heat pump system. This system is in
San Antonio, Texas and is operating at 2, 200 hours running time
for cooling and 1,100 hours running time for heating using ARI
standard 270 and at .068 cost per Kw. This report includes these
variables based on new system performance values. Operating costs
will vary based on total existing system performance and actual
running time. The total percentage of savings is applicable in
all cases.
