Ducted heating systems use central air to heat up houses, and when the heater is on, the home gets warm. If your ducted heating is blowing cold air, the reason can be:

  • Clogged or dirty air filters
  • Pilot light
  • Batteries and setting on the thermostat

Is your ducted heating giving you the cold shoulder by blowing cold air? Why so? Well, there could be multiple reasons. So, before calling a ducted heating technician for help, try these troubleshooting tricks. Check the settings of the thermostat Fan. Does your ducted heating blow cold air at times? Let’s have a look at its reasons.

There are various types of heaters, most of them use central air to heat up their house, and when the heater is on, the home gets warm because of the heating system. Based on the size of your home, it may take some time like 30 minutes to 1 hour of running the system to get the home to a warm and relaxing atmosphere.

People have cold air problems with their heating units and the reasons can only be determined by doing some quick checks on the thermostat and the whole system. For those who don’t have time, or don’t want to create a mess doing all the checks mandatory to find a problem, just give a call to an HVAC specialist to figure out why the air coming from the ducted heating is cold?

1) Clogged or dirty air filters

Air filters are made to capture the debris, dirt, and other particles that the air contains, and these particles travel from room to room if the air filter can’t capture them. The important thing you should not ignore about air filters is that they must be cleaned and changed regularly, which is usually every three months - unless the heater is not being used regularly. Even if your ducted heating system has an inbuilt HVAC system that works in both ways to cool and heat the home, it will have air filters. A dirty or clogged air filter will not allow the airflow through the heater, and as a result, it can cut off the burners that provide warmth and cause it to blow out cold air. This doesn’t happen usually, but it’s possible in homes where air filters are not cleaned and changed for months/years.

2) Check its Pilot light

For ducting heating systems with furnaces, an outside pilot light is a regular problem causing ducted heating blowing cold air from the vents. The Pilot light is imperative in a gas heater if the gas or fuel to the heater is going to be ignited to bring warmth to a particular area. Check the pilot light to see if it’s working, if it is placed outside, that may be the reason behind the heater not blowing warm air. Also, check if there’s a problem with the ignition of the pilot, or with the ducting heating system. Maintenance and repair may be necessary to resolve the issue. If you are recommended to replace some parts, including the pilot, you can get it done by hiring a professional ducted heating technician from Heating Experts who knows how to clean, repair, and maintain ducted heaters.

3) Check the batteries and settings on your thermostat

The thermostat is extremely important for a heating source with central air, whether it’s an HVAC system or a furnace. There can be multiple things wrong with a thermostat; resulting in it blowing cool air instead of warm. Set the thermostat to “heat” mode, if it can work on both heat cool modes. Secondly, set the temperature above the existing room temperature. Also, check the heat is turned “on”, and not only the heat source is on. Some thermostats offer two switches that let you pick the “cool” or “heat” tab, so ensure both switches are working fine. Also, check the batteries of the thermostat and change them if necessary. Set the thermostat to “auto” for the automatic fan selection.
