1. Furnace isn’t turning on
If your furnace is not turning on, the first thing to check is the power supply. Make sure the breaker hasn’t tripped and that you have not had an issue with a blown fuse. Also, ensure that no wires have disconnected or are broken.
After confirming all of these elements are in order, it may be necessary to reset your thermostat according to its instructions. If this does not work, you may need to check for blocked air filters and vents to ensure air can flow freely through them.
If none of this does the trick, it is best to contact a professional, like AC services in Groveland, FL, for further help.
2. Furnace is blowing cold air
If your furnace is blowing cold air, it could be a problem with your thermostat settings, air filter, or vent. First, check to make sure the thermostat is set to “heat” and that the temperature setting is not too low.
It’s also important to inspect your air filters and vents to make sure there are no clogs that may be blocking airflow. If the filter is dirty, replace it, and if the vents are blocked, clear away any debris or obstructions to ensure proper airflow.
3. Thermostat isn’t working
If your thermostat isn’t working, it could be a problem with the wiring or the display. First check to make sure all of the wiring is securely connected and that you have adequate power coming into the system.
If these items look okay, try replacing the batteries in your thermostat, as this can often resolve the issue. If you have a digital thermostat, check to make sure it is properly calibrated and that all of the settings are correct.
4. Water leaking from the AC unit
If water is leaking from your AC unit, it could be a sign of a clogged condensate drain line. This happens when the moisture collected during the air conditioning process becomes blocked due to debris or algae buildup in the line.
The first step towards resolving this issue is to check for any standing water near your outdoor AC unit. If you locate any, clear away the debris and then use a wet vacuum to remove any remaining water.
Next, take a look at your condensate drain line and see if there is visible blockage—if so, use a damp cloth to wipe away the dirt or algae buildup. Finally, pour some bleach into the line and let it sit for a few hours before running water through the line to ensure it is completely clear.
5. No air coming out of vents
If your vents are not blowing any air, the first step is to check the fan settings on your thermostat. Make sure it is set to “on” and that you have adequate power coming into the system.
Next, inspect your air filters and vents for clogs or obstructions—if they are dirty or blocked, replace or clear them respectively. Additionally, ensure that all of the ducts and vents are properly connected and sealed so that air is able to freely flow through them.
If none of these solutions work, it may be time to contact a professional for further help. They will be able to accurately diagnose your issue and get you back up and running.
6. Rattling or banging sound coming from the furnace
If you hear a loud rattling or banging sound when your furnace turns on, it may be due to an issue with the blower motor or fan belt. First, check the fan belt for any signs of wear and tear—if it is frayed or broken, replace it immediately.
Next, inspect the blower motor to ensure it is securely attached and functioning properly. If there are any loose connections, tighten them up, and if the motor appears to be malfunctioning, you may need to replace it.
Additionally, make sure there is nothing obstructing the fan blades, such as dirt or debris—clearing away these items can help stop the rattling noise.
