HVAC Not Working? Here are 5 Potential Causes

Are you struggling with HVAC problems? If so, you’re not alone. At some point, all homeowners experience some issues with their HVAC unit. Not getting cold air through the vents? Not getting any air at all? These are some common problems that people report.

If you’re having issues with your HVAC system, there are ways to fix it. Keep reading below as we discuss the HVAC system in detail, including 5 potential causes for your issues. 

Potential causes

There are plenty of reasons why your HVAC system may not be working properly. Below are the top 5:

1. Filter needs to be changed

The most common reason why your HVAC system may be acting up has to do with your air filter. Have you changed it recently? If not, you need to change your air filter immediately. Air filters should be regularly changed out to ensure proper function. Check the filter packaging for more details and ensure that you’re following the replacement directions accordingly.

2. Thermostat is broken

Is your HVAC unit running but the air coming out isn’t quite cold or hot? Or perhaps it keeps running continuously? If so, then your problem may be due to a broken thermostat. Check to make sure the thermostat is working properly and then take a look at the settings. Most thermostats have an “auto” or “on” setting. 

The “auto” setting will make the system start and stop depending on the room temp. This saves energy and keeps your home a consistent temp.  The “on” setting, on the other hand, will make it run constantly. Setting it to “on” is meant for homes with air cleaning systems and isn’t always necessary. 

3. Pilot light is on

Do you have an older furnace that has been acting up recently? Check the pilot light. In some furnaces, there is a flame that produces heat. This flame can sometimes flicker out, causing the system to stop working. You’ll need to reignite the flame to get it back into working order. For help with this, please contact a professional HVAC technician. 

4. Faulty ductwork

There are a lot of components to an HVAC system and one of the most important is ductwork. The air ducts will take the heated or cooled air and move it throughout the home. If they are clogged, cracked, bent, or damaged in any way, they won’t be able to do their job right.

If you suspect that there is an issue with your duct work, call an HVAC technician today. They’ll be able to inspect the air ducts and offer air duct cleaning if necessary. 

5. Mechanical issues

Tried all of the above and still not finding a solution? Chances are, your HVAC system is experiencing some sort of mechanical issue. HVAC units are highly complex, so if you think a mechanical problem is the cause of your problems, you should contact an expert.
