5 Signs Your HVAC System Needs a Tune-Up

If your HVAC system is acting up, it may be trying to tell you something.

Here are five common signs that your system needs a tune-up:

1. Uneven temperatures throughout your home

If some rooms are significantly warmer or cooler than others, your HVAC system may be struggling with airflow or zoning issues. This often points to ductwork problems or an improperly balanced system.

2. Strange noises or smells coming from the vents

Unusual sounds like banging, rattling, or hissing could mean loose parts or motor issues, while musty or burning smells may signal mold growth or electrical problems. Both are signs your system needs immediate attention.

3. Higher-than-usual energy bills

A sudden spike in your utility bill without a change in usage often means your HVAC system is working harder than it should—possibly due to clogged filters, leaks, or failing components.

4. Reduced airflow from vents

If air isn’t blowing strongly from your vents, it could be caused by a blocked filter, leaking ducts, or a malfunctioning blower. Weak airflow reduces comfort and strains your system.

5. The system is constantly turning on and off.

Known as short cycling, this behavior indicates your HVAC system is struggling to maintain the set temperature. It could stem from thermostat issues, poor insulation, or an oversized unit.
