Very prompt however listening isn't a specialty. I specifically told them that they needed a ladder to get on the third story so when they showed up at 930 pm without a ladder I was upset. Then the service guy says we don't go up on the third story. Um... yes you do. You replaced my entire unit about 2 years ago. You weren't complaining when I forked over $7000 to you. Now they tell me the repair is going to be $800 and that's only labor. I had a 1% chance that I would get a faulty part and I drew the lucky straw! As a homeowner I just scratch my head. Who can afford this garbage!?!
