Called when furnace at vacation home was not firing up consistently, asked to come change thermostat. We were supposed to leave the next day, and they accommodated us and sent a technician that afternoon. Got it changed and seemingly working fine. That night it failed to fire up again. I called to see if they could come back and check again. They accommodated again and found that a piece insulation had been sucked in burners and keeping furnace from firing up. Cleaned and working great now. Didn’t charge for second call. Thanks!
