The answer to 'HVAC system short cycling' is that short cycling, where the HVAC system turns on and off rapidly, is often caused by issues with the thermostat, compressor, or airflow. Common symptoms include uneven temperatures, high energy bills, and reduced lifespan of the HVAC equipment. Some potential solutions include checking the thermostat settings, cleaning or replacing air filters, and ensuring proper airflow through the system.
If the short cycling persists or you're unsure of the cause, it's best to call in a professional HVAC technician to diagnose and repair the issue. Attempting to fix the problem yourself without proper training and tools can potentially make the issue worse or even lead to safety hazards.
