How to Fix Most Common Heating Problems


Statistics suggest that furnace repair companies are busiest during the winter season. The rush results from the lack of a periodic maintenance schedule which is essential for every unit. Most people do not check on the furnace until winter beckons or the system becomes problematic.

Furnace problems are relatively easy to fix. An experienced and trained technician like the one from Morris Jenkins furnace services in Charlotte can always help you keep your system in the best condition. Fixing common heat problems on time will ensure your furnace serves you efficiently for a long time. See below some common furnace concerns and how to fix them.

Noisy Furnace

Most furnaces produce reasonable noise when in operation. You may hear a ‘click’ sound when the thermostat reaches certain temperatures. It then sends a signal to the furnace, likely producing a whooshing noise as air travels through the ductwork. In some furnaces, the blower is louder than in others. Most of the noises above are typical.

Whoever knocking or rattling noise may require an expert to check your system. These sounds suggest a loose component in your system that needs tightening, adjusting, or replacement. Also, a loud rumbling noise can occur when fuel is left in the combustion chamber once the system shuts off. Depending on the issue, you will need a technician to inspect, repair or replace it.

The Furnace Does not Turn on Automatically.

After switching on, a well-functioning furnace will produce heat when prompted by a signal from the thermostat. If your furnace fails to turn on automatically and your home remains chilly, it may indicate something wrong. Like other furnace issues, this may be a quick fix or a sign of a more considerable heating equipment concern.

The circuit breaker may be off if your furnace does not turn on automatically. In this case, all you may need is to flip the switch and get your system working again. Also, a thermostat set to cool or off can make the furnace not turn on. Your furnace will not kick on when the thermostat temperature is too low. To correct it, adjust the thermostat settings.

Other reasons, like faulty ignition and clogged air filters, may require a technician for timely repair.

Experiencing Furnace Short Circuits

Typically, a furnace turns on and off while it tries to maintain the set temperature on the thermostat.

If the furnace cycles frequently without reaching the set temperatures, call in an expert to check your system. A common cause for a short cycle is insufficient airflow in the furnace, which causes it to overheat. Clogged air filters are also another reason your furnace may be turning on and off frequently. Replacing the air filter may resolve the issue, but it doesn’t; you may need to engage a technician.

Furnace Not Producing Heat

Your furnace’s only role is to produce and distribute warm air to make your space comfortable during the chilly winter. Some minor issues like the fan setting on, the thermostat being off, or wrong settings may cause the furnace not to produce heat as required. Such heating problems are quick to correct with minimum effort.

However, if your furnace is not producing heat due to a lack of flame to ignite the fuel, then the problem could be the pilot light. The flame will not catch if there is an issue with the ignition. Hence the surface cannot produce warm air. Pilot light issues require an expert to check your furnace and make the required repairs.


Fixing some of these common heating problems as soon as they occur will save you time and considerable repair-related expenses. Work with an established furnace repair expert to extend your furnace lifespan and save yourself from unnecessary heat problems.
