Posted on in Blog
Though it can be hot in Livingston, Texas in general, you don't want to be left in the cold during the winter. That's why it's so important to take care of your heating and cooling system. The last thing you want to happen during a cold day in the winter is furnace issues. To ensure that your furnace is working properly through the winter, it's important to take care of it year-round. Are you wondering what furnace issues might affect your system? Let's have a look at 5 common issues and how you can fix them.

1. Thermostat Issues

The thermostat works as the brain of your system. If it breaks or malfunctions, it can throw the system as a whole off as well. There can be a few reasons that you're having this issue with it. Firstly, check the batteries. Sometimes a good battery change is all you need to get your thermostat working at its best again. Another simple fix can be setting it back to the correct temperature. It's not uncommon for another member of your household to change the temperature or for someone to accidentally brush up against it. Be sure to check that before calling for help. Finally, it may need to be recalibrated. This is something that you should leave to a professional HVAC company in Lufkin, Texas.

2. No Heat

If you suddenly feel a loss of heat, it can be startling. The good news is that it's usually an easy fix. It can either be due to the filter or the fan. As your furnace works, the filter may start to get excess build-up which can lead to no hot air getting through. A simple replacement can be helpful here. Another issue can be the fan as it only blows air, it doesn't produce heat. It's also good practice to check on the pilot light. This can be the cause of the air not being warm as the pilot light is responsible for the heating. You'll need an HVAC service to rectify this.

3. Air Filter Troubles

Your air filter catches any dirt that goes through it. If it isn't changed often, then you might experience clogs that don't allow the air to flow through. This can put unnecessary strain on your heating and cooling system causing it to lose efficiency. However, this is a simple fix. Be sure to change the air filter regularly and you won't have this issue any longer.

4. Leaks

Your furnace has condensation pipes that run through it that send the water where it needs to be. Unfortunately, these pipes can clog and cause a leak in the system. You may notice water around the system when this happens. Sadly, there's no quick fix for this. You'll need a technician in Nacogdoches, Texas to complete furnace repair.

5. Blower Runs Non-Stop

Have you noticed that your blower hasn't shut off, and seems like it's continuously running? This can indicate a problem with your limit switch. You can start by setting the temperature lower to see if it stops. If it doesn't, the limit switch should be checked. You may need a professional to help you with this process as well as you'll want to be sure that it's done right.
