Understanding Your AC System
What Are the Main Components of an AC System?
To understand why your air conditioning isn’t cooling, it helps to know its main components:
- Compressor: This pumps refrigerant through the system.
- Condenser Coil: This releases heat from the refrigerant.
- Evaporator Coil: This absorbs heat from your home.
- Expansion Valve: This controls refrigerant flow.
Each part plays a role in keeping your home cool.
How Does an AC System Work?
An air conditioning system works by removing heat and humidity from indoor air and transferring it outside. The compressor circulates refrigerant through coils, absorbing indoor heat and releasing it outdoors, while blowing cool air back into your living spaces.
Common Reasons Your AC Runs But Doesn’t Cool
Low Refrigerant Levels
One common reason for inadequate cooling is low refrigerant levels. Refrigerant is essential for absorbing heat; if it leaks or runs low:
- The compressor may overheat.
- The system may run continuously without effectively cooling your space.
Dirty Air Filters
Clogged filters restrict airflow, forcing your unit to work harder. If airflow is restricted:
- The evaporator coil may freeze.
- You’ll notice reduced cooling efficiency.
Regularly checking and replacing filters can prevent this issue.
Faulty Thermostat
A malfunctioning thermostat can misread temperatures or fail to signal the unit properly, leading to inconsistent cooling performance:
- Make sure it's set correctly.
- Consider recalibrating or replacing it if needed.
Less Common Causes of AC Issues
Blocked Condenser Units
Sometimes debris can block condenser units, preventing proper heat exchange:
- Check for leaves, dirt, or other obstructions around outdoor units.
- Clear any blockage to allow efficient operation.
Electrical Problems
Issues with wiring or electrical components can disrupt power flow:
- Inspect for tripped breakers or blown fuses. If you're unsure what to do next, consulting with an HVAC contractor near me can help ensure safe repairs.
