Troubleshooting Your HVAC System

If your home’s heat or air conditioning stops working, there’s probably something wrong with your HVAC system. 

HVAC stands for “heating, ventilation, and air conditioning,” and figuring out problems on your own can be daunting. 

At Mitten Made Properties, we’ve been buying, selling, and fixing Metro Detroit properties for quite some time now, and we’ve learned a thing or two about troubleshooting HVAC systems. Furnaces get quite a workout here in Michigan! 

So we thought we’d offer a bit of advice. 

Before you call a professional, here are some simple issues you should check:

Air Filters 

If your HVAC system isn’t running like it should, the first thing you should do is check the filters to make sure they don’t need replacing. If you pull out an air filter and it’s covered with dust, definitely replace it. Swapping in new filters is an easy and inexpensive maintenance task that should be done at least twice a year to avoid issues – even if it doesn’t look dirty.


Make sure there aren’t any blockages at the air vents! Look for dust, pet hair, or other debris that could be causing an interruption of air circulation.


Believe it or not, your thermostat can be the source of your HVAC problem. The thermostat controls many aspects of how the system works, so if the thermostat is on the fritz, it will carry over to your heat and AC. So before you call in a pro, be sure to put fresh batteries in your thermostat, make sure the temperature settings haven’t been changed, and check the buttons to make sure they aren’t stuck or slightly out of position. If you have a digital thermostat, you can try restoring it to factory settings. If you don’t see an obvious reset button (you’ll typically need to hold it down for several seconds), check the manual or look up instructions for your brand and model online. 

Circuit Breakers 

It’s also a good idea to check your circuit breakers to make sure none have tripped. The HVAC system losing power is an easy problem to fix – but an equally easy one to overlook.

Reset the System 

If the problem persists, try resetting your HVAC system. You know every tech support person’s go-to first step is “turn it off and turn it back on,” and this can also work on your HVAC! Again, you’ll need to reference your owner’s manual or look up your brand and model online to learn how to do this. 

If all else fails, call in a professional.
