Had problems with A.C. That was installed in our brand new modular…still problems 2 years later. Won't honor warranty for a-coil obviously a common problem with this brand :(.

Had unit installed a few years ago. After about one year, condenser coil started leaking. Apparently a common problem with the "Guardian" series. Had to replace it (with a Lennox unit)! Horrible!

Had Guardian (York) 3 Ton condenser installed into old r22 system three years ago. Unit works fine, hums along pumping out that cold air night and day.

Piece of crap. One year old and it is completely shot! Condenser grounded out, shooting flames out the bottom! Ac repair man said don't turn on your burn your house down!

We've had it for about 8 months now. We had one minor issue with it under warranty but the serviceman came right on out. No major issues. The servicemen spent their time installing it, which I think helps with issues. Wish the electric bill would have come down some, but basically, it stayed about the same. I figure at least it is not higher. Works excellent on pushing the cold air out and we have a 10-year warranty for parts, which makes me feel much more comfortable having bought it. Overall, I'm satisfied.
