No one wants to deal with winter HVAC issues. Unfortunately, they still happen. The good news is, these HVAC problems can be easier to handle if you know what to expect and how to react.

Use the following guide to learn about the most common winter HVAC issues and what to do if they happen to your home.

Multiple climate zones

Does it feel like a tropical rainforest in one room and the Arctic Circle in another? Uneven temperatures are among the most common winter HVAC issues. It can be difficult to keep your entire home comfortable if you are having HVAC problems.

If uneven temperatures are an issue, there may be problems with your ducts or vents. Some may be blocked and require cleaning; however, this issue could be caused by other factors. Check each room for cracks or holes that might be allowing air to escape. Inspect windows and doorways to see if you need to seal up the rooms that are not staying warm in the winter (or cool in the summer). You may also need to rearrange furniture to prevent the blockage of heat vents.

No flow

A lack of airflow is another common winter HVAC issue. This is often caused by a dirty air filter. With everything homeowners have going on, it can be easy to forget to check and change the air filter; however, when this filter gets too dirty, it prevents the HVAC unit from working properly. Less air will be able to circulate, and your surroundings will not be heated as effectively or efficiently.

Try to remember to check your heater filter each month. If it is dirty, change it. Always keep a spare on hand in case you need to replace it.

Lack of control

The thermostat controls the system, telling it when to run and when to shut down. If the thermostat is broken, this can cause major HVAC problems. The unit may not turn on at all, or it may run longer than it should. The thermostat may have faulty wiring, it may need to be replaced or it may simply need new batteries.

If your thermostat isn’t operating correctly, try replacing the batteries. If new batteries don’t do the trick to restore normal operation, contact an HVAC professional.

Flying without a pilot

Your winter HVAC issues may be caused by a faulty pilot light. This flame typically remains lit constantly; however, if it goes out or doesn’t burn brightly enough, your system will not operate correctly.

These HVAC problems can be caused by a dirty flame sensor that needs to be cleaned—or the sensor may need to be replaced. Consult an HVAC technician if you suspect your system has pilot light issues.
