  1. Make Sure Furnace Door is Closed

If the door is not closed, it might not work because this is a protective measure to ensure that it is safe. Try closing the door tightly and then try to start your furnace again. 

  1. Check for Thermostat Issues

The thermostat may have an issue allowing the HVAC system to not work. A bad thermostat will cause problems with the system, either making the system to come on too early, too late, or not at all. Make sure the thermostat has power, replacing batteries if necessary.

  1. Install New Filters in AC Unit or Furnace

Bad or dirty filters can lead to all kinds of problems for your HVAC system. If there is a dusty or musty smell coming from your vents, or if your system is not working as well as it should be, it may be that you need to change your filters. You can replace the filters yourself, but if you need more maintenance, call a professional.

  1. Turn Off Your Air Conditioner

If your air conditioning has been on for a while in the summer, it may have frozen components. Try turning off your system for a little bit, and then turn it back on to see if it works. If it does not work, consider calling the professionals.

  1. Check All Vents for Obstructions

Make sure that there is nothing in or around the vents in your home. If it is just one area of your home that is not heating or cooling, a vent may be obstructed. Make sure there is no excess dirt or dust in the vents, and make sure there is nothing in front of them.

  1. Check All the Wires for Your Air Conditioner or Furnace

Check to make sure that a wire has not broken, disconnected or otherwise damaged. This happens more often to the air conditioning units because they are usually outside the home and can be damaged by animals or from your mowers or weed eaters. If you see an issue, do not handle the wires on your own, call in a professional.
