4 Reasons Your Furnace Supplies Cold Air And When To Seek Repair Services

After dealing with the snowy conditions outside, you want to curl up in your coach as you enjoy the warm air from your heating system. Unfortunately, the heating system blows cold air into your space this time. What could be wrong? You'll need a heating contractor to help you diagnose the issue and find a suitable solution. In the meantime, the following are some reasons why your furnace distributes cold air.

1. Clogged Air Filters

Over time, the filters trap debris and dirt and may get clogged. As a result, the dirty air filter prevents the free flow of air in the furnace. This traps heated air into the system, concurrently increasing the internal temperatures. The in-built switch will turn off the system if it is too hot to minimize damage. Therefore, your repair technician may recommend replacing the filter and any damaged components to restore normal functions.

2. Faulty Ignition

If your heating unit does not have a pilot light, it could be the reason it doesn't produce heated air. The component ignites the fuel to sustain combustion and produce heat. Replacing or fixing a pilot light issue can be dangerous. It's important that you leave the task to a technician.

Some units rely on an electronic ignition switch. This could also be defective if your furnace fails to produce heat. The technician will find a replacement and install it. This should resolve the ignition issue and prevent fire hazards in your home.  

3. Insufficient Fuel Supply

Another common issue is insufficient fuel supply. When your gas lines are blocked or you have a faulty gas valve, the furnace may receive insufficient fuel to burn and produce heat. Your gas tank could also be low, or there could be a leak along the gas line. If you are unsure about the fuel issue, switch off the system, evacuate the house, and contact the technician for a repair service.

4. Blocked or Damaged Airways

Your vents could be why you receive warm air from the heating unit. The ducts may have huge holes and cracks that allow warm air to escape and cold air to infiltrate the ducts. However, your technician could examine the extent of the damage and recommend a viable solution. Duct sealing or replacement can prevent warm air from escaping the system.

If your furnace does not meet your expectations, you should seek repair services before it fails. So don't wait until things get out of hand. Call a furnace repair contractor to help you fix the problem.
