When an essential appliance in your home stops working, it’s easy to think that it’s broken. When it comes to your furnace, regular furnace maintenance is essential to keep it running smoothly. Some common HVAC system problems can cause your furnace to stop working or perform poorly. We’ll discuss how to troubleshoot those common problems in more detail in this post. If those standard issues do not correct the situation, we recommend calling an HVAC technician for furnace repair. 

Common HVAC Problem 1: Thermostat

When you have trouble with your furnace, the first thing to check is your thermostat. There are a couple of issues you can check regarding your thermostat. First, see if the battery is low or needs changing. Many digital thermostats will indicate whether the battery needs replacing or is running low. If that is not the issue, or your thermostat is analog, check for any heating devices that may be interfering with the temperature reading. If you have a portable space heater placed too close to your thermostat, you might be interfering with your thermostat’s ability to read the room’s temperature accurately. Finally, make sure your thermostat is set correctly. Often, automated schedule changes or someone else in your home or office making changes has simply led to it being turned from “heat” to “cool,” or vice versa. 

Common HVAC Problem 2: Check Your Air Filter

Check your air filter. Not only does a dirty air filter lower your indoor air quality, but it can also cause your furnace to work harder, causing long-term problems if neglected. Dirty filters can also restrict airflow, causing your house to stay cold even while the furnace is running. Ideally, we recommend that you change your air filters every three months. Some homes, depending on their location and surrounding air quality, might require more frequent changes.

Common HVAC Problem 3: Power and Settings

This next step may seem obvious, but we recommend checking to see if your furnace is on and that the circuit breaker has not been tripped. While this may seem apparent, you’d be surprised how often this scenario happens. It’s possible that if you didn’t turn it off, someone else in your household might have done it or a previous service worker. 

If the power is on, the next thing to check is the settings on your thermostat. When it starts to get cold, it is common for customers to forget to switch their settings from cool to heat. We recommend double-checking that your heat is on and that the temperature reflects the warmth you desire. If those two steps don’t work, move on to the next common issue. 

Common HVAC Problem 4: Pilot Light

Once you’ve double-checked that the furnace is turned on and the circuit breaker works, you can then check to see if the pilot light is lit. If the pilot light is out, follow the instructions in your furnace manual to light it. If you are unsure how to do it, we recommend calling an HVAC technician. It’s always better to call a professional than to play around with your furnace, potentially causing further damage. 

Common HVAC Problem 5: Examine Your Air Ducts

In some scenarios, the problem may not even be your furnace but your air ducts instead. If you have already checked the issues listed above, the next area worth investigating is your air ducts. You can start by going through your home and checking to see if your air vents are open. As you survey each vent, you may also want to peek inside to see if anything is blocking them or has fallen inside —especially if you have young kids or pets in your home. If all the vents are open and clear, the next step is to survey any exposed air ducts in your home for damage or obvious leaks. If none are visible, then it’s time to call in the professional furnace experts.
