1. Thermostat

First, make sure that it’s set on “heat.” Yes, it sounds silly but more people than you think don’t realize this is the problem.

Second, check the batteries on the thermostat. It might be as simple as changing the batteries that been sitting there since last winter. 

Third, try turning the fan switch to “on” to force the furnace to start blowing air.

Fourth, check to see if there is an error code that you can use to troubleshoot. Modern thermostats usually will flash a code immediately at any sign of an issue.

2. Air Filter

Changing the air filter can be an easy solution to your problem. This is something that is they aren’t changed routinely they can get clogged up in turn not allowing the furnace air flow. 

Check to see if the filter is clean and then make sure that all the vent registers are clear of any obstructions. It’s highly recommended to follow the manufacturer’s directions on how often to change the filter.

3. Fuse Box

Make sure that your breaker isn’t flipped in your fuse box. If the breaker has tripped then your system will have no power going to it. Once the break has been flipped back make sure that there is power going back to your thermostat and outdoor HVAC unit.

If the breaker keeps tripping it might be time to call in a qualified electrician to see if your home has an electrical problem.
