How to Fix a Furnace


No matter if you’re in a residential, industrial, or commercial building, having a reliable furnace will definitely help you get the right level of warmth within the area. However, like any other device, it needs to be fully functional in order to serve its purpose. If you encounter any issue, then it’s just right that you fix the right furnace parts to get them working again in no time.

How to Fix a Furnace

The question, though, lies in the how. How can you fix a furnace? Before that, how can you know what problem you are dealing with? This is what we’re going to walk you through in this article.

1. Figure Out What Part Needs Fixing

In general, the first step in fixing something will always point to troubleshooting. This means that you need to look into all the furnace parts and figure out which one of them needs fixing. Doing so will lead you to a definite answer regarding things like what you should focus on, what specific furnace issue you are dealing with, and what repairs will possibly solve it. To do this step, you simply need to check your furnace’s external and internal system, turn it on and off, and look at the plugs and main power system. Checking the thermostat is also recommended to see if the issue lies there rather than the furnace itself.

2. Determine the Issue and Make the Appropriate Repairs

After troubleshooting, you should already have an answer to what is wrong with the furnace. It can range from minor things like leaving the power system unplugged up to major stuff like dealing with a faulty circuit breaker. Whichever it is, expect that there are appropriate repairs that will go with them. To save you time, here is an overview of the most common furnace problems and how to fix each of them:

Dirty Air Filter

If you think your room gets extremely hot despite your furnace being set at the right temperature, there’s a high chance that you are dealing with a dirty air filter. In some cases, this issue may also force the device to stop operating due to the lack of regular airflow, thus, the deactivated system. Fixing this problem is usually just as easy as cleaning your air filter by rinsing it with water or thoroughly spraying it with a hose. Use a gentle brush alongside water to fully get rid of stuck dirt and dust. Detergent can also help, but make sure that it’s mild and not strongly fragranced. It should also be a wash-off detergent rather than a leave-on to prevent further system issues.

Buggy Thermostat

The thermostat in your home or building controls the overall temperature that you will get within the area. It can also be one of the main culprits behind your furnace’s faulty system. You’ll know this if you feel like your home’s temperature can get very irregular at times, even without adjustments. The thermostat may also have issues with its display if this happens. Unfortunately, repairing a thermostat can be complicated. You need the help of a technician if you aren’t used to modifying HVAC systems. You can also just proceed to replace the thermostat if you think that it’s beyond repairs.

Circuit Breaker Issues

Dealing with circuit breaker issues requires bigger repairs. This is because it may involve things like short circuits, breaker trips, overloads, and electricity surges, all of which can be dangerous if done by a non-professional. On the lighter side, some cases may simply involve accidentally leaving the circuit switch for the furnace turned off. Check your circuit breaker first before making any modifications.

3. Consult a Professional

If you don’t want to take the risk of ending up with more serious furnace damage, or if you did the steps above and the issue is still not solved, consulting a professional technician will be your best bet. Since they have all the knowledge, tools, and resources in fixing a furnace, it’s a sure way to finally get rid of whatever is wrong with the device.

Summary

Fixing a furnace can be done either through DIY methods or consulting a professional technician. It will depend on what issue is at hand and how experienced you are in related device repairs. Thus, if you’re not confident in your skills and you are dealing with a somewhat complex furnace problem, then it’s a given that a professional should handle your concerns. Of course, prevention will always be better than cure. This is where the importance of maintenance comes in. Ensure that all of your furnace’s parts have high-quality structures and stay in their best condition. Doing so will significantly reduce your need for constant repairs.
