I would give them a zero if I could. The owner was rude and unhelpful when I tried to narrow down when the tech would be there. I have tenants freezing in my rental property and she could care less. She said between 12-3 and I called to see when at 2:00 when nobody had showed. I asked if she could call the tech and if he could call in way so we would know. She yelled NO and offered no assurance if when I could expect him to show up. I told her make it 2:30 or forget it. She said no so I hung up. She consequently called me at 2:30 stating in an almost joyful tone that she was canceling the appr. Good luck getting any business when you treat people in this manner.
