Our Water Furnace unit (Envision 049) is not even four years old. Last Nov. it quit. A service man from Porter & Heckman, who installed the unit, came and spent four hours to decide the compressor was bad. He came back four days later to replace the compressor. Only a week later the unit quit again. Another serviceman spent two hours and could not find problem but he did make the unit run again by simply shut off power (from circuit breaker) for few minutes then turned back on. Six days later it happened again. This time I did the same thing by shutting off circuit breaker and turned it back on. The unit revived back. I called Porter & Heckman to report the problem. The man in charge told me blower needed to be replaced. Am I the first one getting hit by both compressor and blower at the almost same time in this early stage of the unit? Or the serviceman did not diagnose correctly? Although the unit is still under warranty, for both replacements we were billed $713 for labor, reclaim refrigerant, nitro boost, and trip. I understand I’m responsible for the labor charge but am I responsible for refrigerant ($165) and nitro boost ($85)? Any input will be greatly appreciated.
