If you are to extend the life expectancy of your heater, there are numerous things that must be taken care of if you ask why is my furnace blowing cold air.
A heating and cooling system will malfunction primarily due to among its 3 elements - circulation system, thermostat or the heat/cold source. If the system is not running, it is most likely the source of the heating system at fault. The system could have lost power or fuel may not be reaching the unit. It definitely may not be igniting if the fuel of the system is oil or gas. On the other hand, if the system turns on but the heat or cool is not reaching your space, it is most likely the circulation system or the blower of the unit. A defective thermostat would cause the system from switching on and off consistently. It might prevent the system from switching on either. Whatever the factor for the device to breakdown, you can constantly stay clear of such perilous scenarios by maintaining the system regularly.
The very first step with a malfunctioning heating system is to make sure that the system is getting power. There are some heating systems which have a separate power entrance. Repeat this when more and see if the system would begin.
Examine to see if the thermostat of the unit is set appropriately. You can raise or lower the setting by 5 degrees if required.
You should make sure that all power to the device is turned off before meddling with the unit. If the system is making use of gas and your residence is smelling of gas, do not attempt to turn any lights on or off. Your heating and cooling system should be expertly serviced every year without fail.
