I came back to Phoenix a bit early this year to 104 degree weather and found one of my heat pumps wasn't pumping any heat out of our place! I called up on Labor day and got an owner on the phone. He asked if it was an emergency and offered to have somebody come out but I decided it could wait a day. The next day a friendly tech came out and found we were low on coolant which caused the unit to freeze up (literally). Our heat pumps are 26 years old and it would have been a perfect time for a scammer to hit us up for a new system but these guys are honest. The tech said we could get another year or two out of our units. He defrosted the unit, added some coolant and gave us a very reasonable bill. Even took a look at the 2nd heat pump and topped it off for free. Super service saved me a pile of cash - and when I mentioned Yelp I even got a discount. Thanks guys!
