I had to get a relative's A/C fixed in a hurry -- family medical emergency. I called Gibson based on Yelp reviews, but later began to wonder whether the owners and/or their friends had written these reviews.
On the plus side: After a day in which a (very expensive) part was obtained, the unit was promptly fixed and seems to be working fine.
On the minus side: I was spending all my time at a hospital, so pre-paid for the repair (scary!). The technician who came out was generally uncommunicative and distant (Asperger's?).
Then, getting a receipt (to be reimbursed by the family estate executor -- but I should have had a receipt in any case) was like pulling teeth. You would've thought I was asking for the money back! The phone clerk, when I asked the second time, behaved as though **I** were at fault because I didn't get a receipt the first time! Then, of course, when I finally got a receipt, my name was badly misspelled.
So it isn't all nice breezes with this company.
