Hello Group, Problem my sister had my brother install new gas forced air furnace. He didnt convert it to natural gas, it would work for several hours as needed then kick off and need to be reset. While trying to keep it running he realized his mistake after 3-4 days. He then converted it and it ran as it should for about a day and a half. My sister then called a tech in to check it. The heating tech says it is ruined and that a new heat exchanger is $80.00 less than a new furnace. He states the exchanger can not be cleaned. Sorry I don't have the furnace name or information except it is 90% efficent. If it matters I can get the information. I just don't want my sister to get burned. Located in the beutiful fingerlakes area of central NY. Thanks in advance for any information.
