The furnace is quite possibly one of the most important systems in your home. As such, you need to take good care of it so that it always works optimally. This won't be that difficult as long as you avoid these common furnace maintenance mistakes. 

Not Switching Out the Air Filter 

Many homeowners don't realize just how important the air filter is to the longevity and efficiency of their furnace. Then when it's not changed out regularly, dirt and debris can get in your heating system and cause costly repairs that could have easily been prevented. 

Don't let this happen to your furnace and its integral parts. You need to be changing this air filter out every couple of months, or at the very least when it's completely covered in dirt and other particles. When replacing this filter, make sure you choose a high-quality replacement that fits your housing unit perfectly.

Leaving the Furnace Running 

If you have a busy schedule, it's quite easy to leave the furnace running throughout the day. Although this mistake is pretty common, it will drive up your energy bills and prevent your furnace from lasting as long as it could.

If you're not going to be in the house for some time, lower the thermostat to where the furnace doesn't kick on. It helps to invest in a programmable thermostat as well. You can set a particular heating schedule based on when you're at home. So when you leave for work or attend school, the thermostat automatically will shut off your furnace. 

Blocking Air Vents 

When you move things around in your house, sometimes the vents connected to your furnace can get blocked. This restricts airflow and could cause severe damage to your ventilation system if you're not careful. That's why any time you move furniture or boxes around, make absolutely sure your vents are free of obstructions. 

It helps to go from room to room when completing these inspections just as a precautionary measure. While you're inspecting the vents, go ahead and get close to them to ensure they're open. It's surprising just how many homeowners leave their vents closed on accident.

The furnace is a vital appliance that keeps you and your family warm, and it's also one of the more expensive systems to replace in your household. So that you don't have to deal with costly repairs and replacements, know exactly how to care for your heating system from the beginning.
