Feather River Aire offer HVAC services in Live Oak. Our technicians suggest simple ways to fix the furnace system if it blows cold air:
• Check the furnace’s thermostat settings. Ensure that the thermostat is set on Heating mode and the fan is set on auto mode rather than on mode.
• The next thing you should check is the vents. Ensure that all the vents are open and that nothing is restricting the path.
• If the air filter is dirty, buy a brand new air filter.
