"I had the AC person out who had been servicing my AC as well as my mom’s for years and he told me the unit was shot and I needed to replace the whole thing. I called Pacific Air this morning, they came at noon, had it up in running 20 minutes later. Only charged me the service fee. While I am sad about the other guy trying to rip me off, I am so happy I called Pacific Air. An honest, fair, professional company."
