If he was registered auditor I would be reporting him.
I had an audit done last year about this time. He did a blower door
test, infrared image scan throughout the house, told me where I need to
insulate, caulk, etc. He sent a report with the scanned images. Using
his info, we decided on some major work of foam insulation on roof deck
and rim joist. Then added a new furnace and central AC system including
duct work (from a boiler/radiant heat system). After all was complete,
we recalled the auditor to conclude the difference and he was
flabbergasted at the drop of over 50%. We received rebates for the
audit, the furnace/AC and the insulation totaling close to $4000.
According to our energy company, we are now top 3 in efficient homes
within our area.
Auditing can be very favorable.
