I would give them a zero. The service guy Chad was unprofessional and all he did was try and hard sale the whole time. Came out for a yearly maintenance and found all these problems. It's 3 years old and they put it in. You know the commercials where they say we don't sell you services you don't need well they're talking about this company. If they call to maintenance your air system, don't do it. They want to charge me 45.00 for a sales call not an air conditioner check. DONT LET THEM RUIN YOUR DAY OR RIP YOU OFF!
