When you turn on the heater in your home, you should be able to expect warm air from the vents to flow through your house. If your system is blowing cold air instead, it could mean one of the following problems.

Thermostat Issue

The first thing you should check is the thermostat. The setting may have been inadvertently changed. This is a common scenario in homes with touch-screen thermostats. Someone merely bumping one could accidentally adjust the setting to a lower temperature or turn the fan on instead of the heat. Otherwise, the thermostat might actually be faulty.

Clogged Filter

A clogged or dirty filter will also have a significant impact on the temperature of the air coming through your heating system. Air must move through the system to bring heat into your rooms. A clogged filtration system can severely interfere with this process. Simply swapping out the clogged filter for a clean one might solve your problem.

Dirty Flame Sensor

The primary role of the flame sensor is to determine whether the burner is producing warmth to heat the air as it moves through the ducts. A dirty flame sensor will not register whether the burner is heating. In most cases, it will give a false reading. If your system starts to blow warm air and then suddenly blows cold air, this is an indication that your sensor is dirty. Do not attempt to solve the problem yourself. To avoid damaging your unit, seek the services of a trained professional from Trade-Mark Air Conditioning in Ingram.

Extinguished Pilot Light

The pilot light provides a sufficient flow of gas, which keeps the burner ablaze. However, any issues with the pilot light mean that the burners will not be heating the air. This is a common problem with some heating systems. A dirty pilot light will not ignite to properly start your furnace, which leads to cold air blowing out.
