If you already had to deal with a myriad of heating issues during the last cold season, you won't want a repeat of the same this year. Heating issues are not just annoying to deal with, but they can also be quite expensive in the long run. You could be racking up huge energy bills or spending a fortune on spare parts.
If you wish to avoid all this, you should fix the main cause of the problem before the cold sets it once again.
Clean or Replace Your Filters
This is a fairly simple problem but one that is seen far too often in many homes. Air filters tend to get ignored after a while, and once they become dirty or clogged, the airflow becomes restricted. This will not just affect the quality of indoor air, it can also cause the limit switch to blow.
Luckily this is a problem you'll find quite easy to fix, and once fixed, you should notice an improvement in the efficiency of the furnace.
Pilot Light/Ignition Control Issues
If your pilot light or furnace ignition system is faulty, you may not be able to heat your home. These are the systems that start the combustion/heating in the furnace.
These problems can be the result of issues with the thermocouple or just a draft finding its way to the pilot light. The solution, in this case, could be as simple as a few repairs or having to replace the whole ignition system.
A noisy furnace can be hard to live with. Even if the furnace is located in the basement, it is hard to ignore squeaks, rumbles, and rattles, and you shouldn't ignore these sounds. A noisy furnace usually means that there's some sort of mechanical problem, a clogged burner, or a reduction in the airflow. Ignoring these noises could mean that excessive wearing is allowed to take place, and this can reduce the lifespan of your furnace.
The thermostat is what tells your furnace when to turn on and off. If your thermostat is sending the wrong signals to your furnace, it could be turning on at the wrong time, not providing enough heat or not turning on at all.
Thermostats are fairly simple components, and if yours can't be repaired you should replace it. You can even ask your heating contractor to install a smart thermostat instead. This can also improve the efficiency of your heating system.
