Boy, am I glad I checked out Air Zero on the Web. We'd been given an exorbitant quote from another AC repair company, so I called for a 2nd opinion. Their quote was $250 less than the company we'd been dealing with - someone we thought we could trust. Their technician Richard was professional, polite and thorough. No high pressure - and he replaced the damaged ductwork with a better product. We're snowbirds, but we'll be calling Air Zero next fall for a regular service call for sure. Air Zero - you're the best. Don't ever change!
