If you’re worried your heating or cooling may be malfunctioning, here are some warning signs to be aware of. The faster an HVAC malfunction is detected, the faster it can be repaired, saving money and frustration in the long run.

HVAC System Issues: Signs to Look Out For

Does the System Run Constantly?

The first sign to be aware of is an HVAC system running constantly without properly cooling or heating the home. This may not be an emergency repair situation, but it should encourage a maintenance appointment to prevent serious problems from developing. Thermostat issues may also be linked to problems with inconsistent cycling.

Are There Any Disconcerting Noises?

Rattling or grinding noises when turning on HVAC systems is another red flag. The problem may be as minor as debris in the line but should be maintained immediately. This is especially true if the sound is coming from within the unit’s interior.

Is There Any Dirt Near the Ducts?

If you see dirt or dust near the home’s air ducts, this could mean they’re clogged. A specialist should inspect them and clean out any particles before they lead to serious issues in the future. It may be tempting to try doing this yourself, but if done improperly, it can lead to worse complications.

Is There a Strong Odor Near the System?

A strong smell near the HVAC system itself is another potential sign of problems. This could be caused by an accumulation of mold, dirt, or bacteria, none of which should be left in the unit. These particles, especially if aerosolized through the home, could lead to serious health problems.

Are There Puddles of Water Near the System?

Puddles of water or leaks around HVAC systems could be signs of a major HVAC malfunction. It could be symptomatic of problems like a loose connection or faulty seal. Large amounts of water pooling may necessitate replacing the HVAC system entirely.

Any Changes in Airflow?

Marked changes in usual airflow can be a sign of deeper issues in the HVAC system. For example, a clogged line might not be delivering cold air where it needs to go, and whole rooms may be ineffectively cooled.

What About the Indoor Humidity Level?

Finally, a failing HVAC system might negatively impact your indoor humidity levels. Unusual humidity levels could be a sign of problems with the HVAC system filtration systems.
