"Worst upgrade ever!!!!!"

1.0 rating
Very Unsatisfied

I upgraded to a forced air/air conditioning system form a burnham steam boiler system. I thought the steam system was a pain to add water all the time and drain out the rust from the boiler. Every year we had to tighten the valves and nuts on the radiators, and they always seemed to leak a little.. I thought this was it, a high efficiency gas furnace and high efficiency air conditioning I would never have to pay for repairs again. WOW!!!!! Was I wrong, I paid $12,000 to have this system installed in my small cape sytyle house 1,100sq. feet, and have had 29 service calls in 2 years and the heat and ac have been out over 2 dozen times. I paid out of pocket $4,000.00 for repair labor not cover under warranty, in addition to $300 annual service contract which basically covers a cleaning and ac checkup. I would have never replaced this steam boiler which was only 7 years old if not conviced by the gas company energy audit that I would never have a problem for 20 years on a new system. They were dead wrong. Lost the heat the first month after install , was a bad circuit board , we froze fro a week while they got a board from canada. Very< Very, VERY, disappointed. I am going to sell this house and get a condo. Thanks to AAAAMERICAN Standard>>>>>>
