They were polite and prompt. But that's where the positives end for Absolute Zero. I'm currently shopping for a new Trane A/C unit. I drove by and saw their van parked in my neighborhood so I decided to give them a call. They were 40% higher than the other quotes I've received. I was quoted $8,200 for a new trane installed. Make sure you shop around, the A/C business is a very sketchy business in Arizona. I'm sure they do good work and they are SRP certified but to me the price is just way too high.
