Furnace Issues that could happen

Furnace issues can happen out of the blue. It is important to remember to contact us any time the furnace has an issue. By having it inspected regularly, you can help prevent further damage to the parts of it. If there is an issue with the furnace, we can inspect and repair it as soon as possible for you. This will help you to have an efficient furnace as well.

Furnace issues with the filter

One of the furnace issues you might notice deals with the filter. A clogged air filter is one of the biggest causes of furnace problems. If your furnace turns on but does not blow hot air very long, there is a good chance that your filter is too clogged. When dust builds up on the filter it reduces airflow through the system and this can cause your furnace to shut off. So check for dirty air filters. If this is the issue, it could have caused soot to collect in your heat exchanger. So make sure you schedule a non-emergency furnace cleaning and safety check.

Other components

Sometimes the furnace issues occur because of components. If the furnace does not work, it may be from the thermostat. Make sure the thermostat is set correctly. This is more common with programmable thermostats because you might have set a program last season, but forgot to adjust it as the temperatures have changed.

Check the circuit

Occasionally, something has caused the circuit breaker to the furnace to trip, turning it off. Also, there is usually a switch (looks just like a light switch) near the furnace that turns it on and off. Verify that nobody turned this off by mistake, while trying to turn off another light

Modern gas furnaces no longer use standing pilot lights. Instead they use either intermittent pilot or hot surface ignition to start the furnace. These are more efficient than a standing pilot light because they are not constantly burning a small amount of gas just to keep the furnace ready to start. When the thermostat signals the furnace to switch on, electricity runs through the igniter and heats it up. If you notice an issue with the furnace, make sure to contact us so we can inspect it for you.

Furnace Noises you might hear

Furnace noise should not be ignored if you hear them. Heating systems are an important part of your home. They help keep you and your family members warm during the cold winter months. It is important to understand when your heating system might be in need of repairs.  A common sign that your system might need repairs is when you hear the system making strange noises.  It is important to catch the need for repairs in time to have them fixed before they cause larger, more complicated issues.

Grinding furnace noises

If you are hearing a grinding noise, this can be a common noise heard from a heating system that is having problems functioning properly.  When you hear a grinding noise, it usually means that some of the parts in your heating system might be scraping against other parts in the system. The grinding noises could also be a sign that a bent fan blade is striking a metal component that is nearby, a part of the motor could be overheating, or a piece of debris could also be stuck in the blades of the fan.

Banging sounds

A loud banging noise coming from your heating system could mean that your radiator is broken or not functioning properly.  Replacing a radiator can be very expensive. It can also be time consuming. You will want to be sure you investigate a banging noise immediately.  A banging noise that occurs when the heat kicks may mean the radiator is in need of repairs.

Humming noise

Another common noise heard from a defective heating system could be a humming noise.  A common cause of this type of noise could be caused by a few things. One is that the heating system is working too hard and might be in danger of shutting down.  The humming can be caused by the motors in the fan. It could also be another part of the heating system working too hard. The noise could be from the job it is designed for. If you notice an odd noise or anything out of the norm, make sure to contact us. We can inspect the furnace and HVAC system for you.
