We have a heil gas furnace that is about sixteen years old and for the last two winters it has been blowing cold air. But not consistently. Sometimes it will actually blow warm air. When it blows cold air it just keeps running because it does not come up to the temperature of the thermostat. We have had a repair man come twice so far and still having the same problem. First visit he cleaned the ignitor. Second visit he replaced it. This is costing a lot for him to keep coming and not fixing the problem. HELP!
