I contacted one of the larger AC companies in the Valley about my upstairs unit which was on the fritz. The unit was under warranty for parts but I would have to pay for the labor. The price they quoted seemed outrageous to me, so I called High Efficiency. They quoted a price which was less than half my original quote. Gus was out early the next morning and had me up and running in less than an hour! He was friendly, professional, and didn't try to sell me anything unnecessary. These guys will now be my go-to call for any A/C work! Couldn't be happier, and the 1 year warranty on their work gives me some great peace of mind.
