I purchased an $8000 system the sales person told me on Thursday that the crew would arrive first thing Monday morning at 8 AM
the crew arrived at 1:30 PM after an hour that crew left because of a medical emergency the next crew stayed until 730 told my friend that they were done my friend has post concussion syndrome and cannot handle a hot home five minutes after they left power to the unit went out. I called customer service chandra told me the crew said ran them of.. absurd ive a security cam observed everything
Incidentally i observed one tech looking at items in my living room and later walked in my den and was looking at things; snooping around in a home is not part of any ac install imho
