We have a 5 year old furnace and with the recent cold spell the bearings burnt up in the condenser. I called at 530 a.m.and they returned the call within 5minutes. Promised someone would call by 9. They had someone there by 11. He had to order a part. The furnace was fixed by 230 and they are submitting my claim for warranty on my part so we can get our moneyback. Very pleased!!
