3 Things That Can Cause Your Central Heating Unit To Mess Up


Now that winter is quickly approaching, it is that time of year when many people start turning on their central heating units. After going several months without being turned on, a lot of things can happen to cause your heat not to work properly. Here are three things that can cause your central heating unit to mess up.

1. Dirty air filters.

It should go without saying that you need to keep your air filters clean in order for your heating unit to function as it is supposed to. However, sometimes it can skip your mind that you need to replace or clean your unit's filter.

After you have turned on the heating unit, if you find that it is not heating your home the way it used to, check the filter. If the filter is dirty, it can cause the heat in the heat exchange to build up. This will then cause the limit switch to tell the heating unit that it needs to turn off. So, even though your home hasn't been heated to where it needs to be, the unit will not continue to put out warm air because it will think that the house is warm enough.

You should always clean or replace your HVAC filter at least monthly. This will help ensure that your unit continues to work efficiently in your home.

2. Faulty thermostat.

Your heating unit can't work if the thermostat isn't working properly, so you may need to troubleshoot it. You should try setting the thermostat several degrees warmer to see if your heating unit turns on.

Another way to see what the issue is with your heating unit is to take the cover off of the thermostat and inspect the wires inside. You should only do this after you have turned the breaker switch to the off position - that will ensure that you do not hurt yourself. If any wires are loose, that could be the problem, so simply tighten them up and turn the breaker back on to see if that fixed the problem. If not, turn the breaker back off and continue troubleshooting.

If you need to continue troubleshooting your thermostat, you will need to unscrew the red and white wires inside and wrap them together. Then, turn the breaker for the thermostat back on to see if the heat comes on. If it does, then you know that you need a new thermostat. If it still doesn't work, it's time to call in an HVAC repair professional.

3. Unlit pilot light.

If your HVAC unit uses gas for heating, then you could possibly just need to light the pilot light. If your pilot light won't stay lit, then you could need to have the thermocouple replaced, or the pilot tube could just be blocked.

My website offers you simple solutions to small plumbing issues and a short guide to help you determine if your best option is to call in the professional plumbers.
