What is the warrenty on the heat exchangersPost created: 2012-12-09 Type of Equipment: Furnace Views: 14This question was created on the page: http://www.furnacecompare.com/furnaces/carrier/weathermaker-9200.html. Model 9200 has been owned for 15 years. The heat exchanger has failed and the house has filled with carbon monoxide. We have had to air the house and turn the furnace off completely. We were told that carrier covered ther heat exchanger for the life of the furnace. Everything else works well. Since finding the problem we no longer have headaches. Your Answer |
