What Are the Most Common HVAC System Problems?
Your HVAC system is the backbone of your home’s comfort. But like any machine, it can encounter issues that affect its performance. Let’s take a look at the most common HVAC system problems you might face and how to recognize them.
Why is my HVAC system blowing warm air?
A common issue with HVAC systems is blowing warm air when you expect cool air. This can happen due to several reasons, such as:
Low refrigerant levels due to a leak.
Dirty air filters, which restrict airflow and cause temperature imbalances.
Thermostat malfunctions where the settings aren't properly controlling the system.
Why is my HVAC system making strange noises?
Unusual sounds from your HVAC system can be alarming. Common noises include:
Banging or clanking, which may indicate loose parts or a broken fan.
Squealing or screeching sounds usually point to problems with the blower motor or belt.
Rattling often happens when debris is stuck in the system.
These noises signal that something needs fixing and should not be ignored.
Why is my HVAC system not turning on?
If your HVAC system is unresponsive, it could be due to:
A tripped circuit breaker or blown fuse.
A malfunctioning thermostat, which may fail to send signals to the unit.
A dead capacitor, preventing the system from starting.
Always check the thermostat settings and electrical components before calling for professional help.
Why is my HVAC system running constantly?
If your HVAC system never seems to stop running, this could indicate:
A dirty air filter, which blocks airflow and causes the system to overheat.
An improperly sized unit, where the system is too small for your space and struggles to maintain temperature.
A faulty thermostat, which could be reading the wrong temperature and preventing the system from cycling off.
