Most homeowners never notice a furnace problem until winter. When the temperatures start falling and you realize that your house is not as comfortable, that is when you bother yourself with your furnace. This is definitely one of the worst practices in home maintenance. Every once in a while, you need to inspect your furnace and ensure that it is working properly. Needless to say, the sooner you notice the furnace problems, the cheaper the repairs will be. The purpose of this post is to help you understand the most common causes of furnace problems.


Poor maintenance

As aforementioned, most homeowners don’t bother themselves with the furnace until the cold season. If you are not scheduling annual furnace inspection and maintenance, it will not be long before you start dealing with serious breakdowns and problems. The purpose of the routine inspections is to help the appliance to run efficiently and reliably all through. Lack of maintenance is the number one cause of furnace problems.


Tear and wear

With time, the furnace will suffer from tear and wear. This is an inevitable problem regardless of how well maintained it is. Tear and wear usually leads to airflow problems. This will in turn cause heat-control-related issues. It is common to start noticing overheating when your furnace is old. This is because of tear and wear. At this point, the best way forward might be a complete appliance replacement.


Dirty filters

When the filters are clogged or dirty, you will start noticing myriad problems. Clogged filters cause a reduction in airflow, thus causing the furnace to work harder in order to circulate air. With time, clogged filters may cause damage to the limit switch. This is the switch that controls the fan. If you don’t act fast to handle the required furnace repair Oshawa, you might end up needing a whole new furnace.

Pilot control problems or electric ignition

When the ignition is faulty, it will lead to problems in heating. This problem can be caused by a number of things among them thermo couple problems, clogs and drafts. All these will result in unlit pilot light. Needless to say, this will lead to heating problems.

Malfunctioning thermostat

At times, the furnace is not the root cause of the heating problem. The heating problem might be caused by a faulty thermostat. This is the unit that regulates the temperatures. A malfunctioning thermostat will cause fan problems or ruin the comfort levels.

Furnace that isn’t heating

There are two problems here; a furnace that doesn’t heat at all or one that doesn’t heat enough. The issue of a furnace not heating at all results from thermostat settings, gas, power or pilot light. If a furnace is not heating enough, the problem may be clogged filters or it may be that the furnace is the wrong size and therefore can’t produce enough heat.

Furnace problems are common. You just need to make sure that you keep an eye on yours and give it the attention it deserves. You also need to change the air filters regularly and keep an eye on the thermostat. These are the two main causes of furnace problems.
