If you are using a furnace as your primary heating source this winter, you need to make sure it is proper working order. By paying attention to odd or unusual symptoms coming from your heating unit, you can save yourself many headaches this winter season. Here are some things you should be on the lookout for.

No Output of Heat

One of the most obvious ways to know your heating unit is not properly functioning is if there is little to no heat output. There are some things that cause this to happen that are not difficult to fix. For instance, the breaker in the electrical box could be shut off. However, if everything is connected and switched to the "on" position, then the problem is going to require a professional, like G K Mechanical (1997) Ltd, to service the unit to determine what is wrong.

Loud or Unusual Noises Coming From the Unit

Another issue you could have is if you hear any loud noises coming from the unit. Furnaces are typically fairly quiet when they are on. However, loud banging noises when it comes on could be the signal of a problem. There could be a problem with the blower motor. This can be fixed with a simple adjustment or repair. However, the ignition to the furnace could be delayed, which poses a more significant issue that requires immediate repair to ensure your heat runs properly.

Strong Smell of Gas

Many homes have furnaces that are powered by natural gas. When you first turn on a heating system, especially at the beginning of the cold weather season, it is fairly normal to smell a burning smell or the faint scent of burnt fuel. This is due to the fact that the system has been off for a long time. The burning smells are usually due to the presence of dust or residual fuel in the unit from last winter. However, if you notice a scent of natural gas, you may have a significant gas leak. You need to get out of your home immediately and call the gas company and the fire department to handle this problem.

Presence of Carbon Monoxide

If you live in a home that has gas appliances, you likely are using a carbon monoxide monitor. Like other gas appliances, gas furnaces can cause carbon monoxide to be present if they are not vented properly. If the monitor goes off, you will need to have a HVAC professional come and test your furnace and other appliances to see what is causing the leak. In the meantime, you need to turn your gas appliances off and open your windows to vent the home until the problem can be fixed. You may even have to leave your home until the leak is repaired.

If you notice any of these problems with your furnace, you should consult a professional HVAC technician to fix any issues. It may also be smart to test your heating system well before the weather becomes cold to ensure you are not left in the cold this winter.
