If you use a furnace to heat your home, it is important to know what the most common types of issues are that your furnace could develop, so that you can avoid these problems.

#1 Reduced Air Flow

A common issue with furnaces is reduced air flow. This is really easy to solve. To get the air flow going again, all you need to do is change out the air filter. When the air filter gets really dirty and clogged with debris, it can prevent air from flowing into your furnace. This will cause your furnace to continue to work harder, pulling in more air to try to heat to meet the demands of your home.

If your filter gets too clogged up, it can cause additional problems as well. A clogged filter, left un-replaced, can lead to damage to the limit switch and thus the fan for your furnace.

This can be prevented by changing out the air filter on a regular basis. It is better to change out the air filter on your furnace every few months.

#2 Faulty Thermostat

Another issue that comes up with furnaces is a faulty thermostat. You need to make sure that you keep an eye on your thermostat. Purchase a portable thermostat and keep it in your home. Make sure that the temperate on your portable thermostat matches with the one on your wall that controls your furnace.

If you notice a continuous big discrepancy between the temperature on these two devices, your thermostat may be faulty. You can also tell if your thermostat is faulty if it seems to not come on when it is cold or if runs for too long when the house is already warm.

Faulty thermostats are really common as your furnace ages. If you want your furnace to operate effectively, you need to keep an eye on it. Make sure that the temperature in your home and your thermostat line-up and make sense. If the temperature doesn't make sense, or your furnace is not kicking in when your home is cold, you may need to have your thermostat replaced.

When you have your thermostat replaced, consider installing a smart thermostat. A smart thermostat will allow you to control the temperature of your home remotely and will allow you to set and schedule your heating to turn on and off at specific times. 

Make sure that you keep the air flowing in your furnace, and keep your eye out for faulty thermostat issues. These are two of the most common types of issues that your furnace could develop that could impede your furnace's ability to function.
