Smart Tech Refrigertion and AC

Terrible service
They made an appointment with me to fix a a.c unit that wasn't heating up, at 4 pm, at 4.30 pm he called me and told me that he was running 45 minutes late, at 5.pm did the same thing, at 7 pm I left, he never showed up, and never answered his phone.
The house is s rental and 70 miles from my home, so I wasted my entire afternoon for nothing.
This guy should not be in business.
Do not use him.
He doesn't care about people.
