All I know is that when Action Air Conditioning, Heating & Solar comes out to do the job, it gets done right the first time! They solve all my problems. The men are very polite and very professional and knowledgeable. They know what they're doing. That's hard to find in most companies, they're always having to come back out to fix things 2-3 times. Not the case with Action Air! I'm not just saying that, it's the truth!
