If you’ve ever had to turn on your heater in winter only to discover that the heater is blowing cold, this blog post is for it. A heater isn’t just a luxury in the winter, it’s essential. Furnaces are an important part of your heating system. Although the heating season is ending, if your furnace is blowing cold, it is time to get on top of things before you become frozen in the winter months.
Is Your Furnace Blowing Cold Air?
Continue reading to find out five common reasons heaters could blow cold air. This article will help you identify what could be wrong with your furnace, and how to address it before it becomes more serious. Although some of these furnace troubles can easily be solved by DIY projects for homeowners, it is important to contact an HVAC technician for expert AC repair in Vadodara and complete troubleshooting.
1) Incorrect Thermostat Setting
Sometimes it is as easy as changing the thermostat to fix a problem with your gas or electric furnace. The thermostat may not be adjusted correctly if the heater blows cold air. This is often the case with dual units that include both air conditioning and furnace. The easiest way to fix this is to turn the thermostat fan on, adjust the temperature and switch to automatic instead of “on”.
If a thermostat is broken, outdated, or not working properly, the problem can become more complicated. This situation is more serious and requires professional HVAC technicians to diagnose.
2) The Heater Isn’t Warming Up
If your HVAC system is still blowing cold, it could be because the HVAC system was just turned on. You should wait for the hot air to begin blowing out before you turn on your HVAC system. Because there is still heat in the unit, a blower fan will continue to run when it turns on.
This is a common problem when the heater turns on for the first time in the season. It will take some time to warm up, so check back after ten minutes and then move on to the next reason if it is still cold.
3) Failed ignition or flame sensor
Failure to ignite the ignition may also cause the heater not to blow warm air. Old furnace heaters had a pilot light that was responsible for lighting and heating the air. The heater will not generate heat if it fails to ignite, or if the light itself isn’t working properly.
An issue with the gas supply could cause a pilot light to stop working or not to light at all. Either the gas supply isn’t reaching the furnace heat exchanger or the gas supply isn’t sufficient to light the flame and continue it on. An HVAC professional is the best person to inspect it. The furnace repair of the pilot light is dangerous.
4) Leaking Ductwork
Cold air must be sucked into the furnace’s heat exchanger and heated before being pushed out of your home via air ducts. These air ducts may become leaky or have holes. This could be because they are old, worn out, or little animals that get into them.
If your heater is not turning on but you have cold air blowing from the furnace, it’s a good idea to inspect the ducts for leaks or cracks. These could be blocking cold air from getting to the heater.
5) Restricted Airflow
Clogged or dirty filters can reduce the heater’s efficiency to the point it won’t heat. Dirty or clogged filters can cause a reduction in the flow of air through your HVAC system. This will reduce the heat coming into your home. Your heater may also be forced to work harder due to a reduced or restricted flow of air.
Your furnace will shut off if it starts to heat up.
