When a heating or cooling system does not seem to be working as expected, it can be tempting to call for professional help straight away. However, there are a few simple checks that may resolve minor issues without specialist support. Taking a short amount of time to review these areas can help identify whether the problem is straightforward or whether further assistance is needed.
Check Power, Batteries and Controls
One simple step is checking the thermostat. If the display is blank or unresponsive, replacing the batteries may restore normal operation. It is also worth confirming that settings have not been adjusted accidentally and that the system is set to the correct mode
Look for Visible Damage or Vibration
Outdoor units should be checked carefully for loose parts or damaged wiring. Garden tools and general wear can sometimes affect external components. Excessive vibration may signal worn bearings or unsecured fittings. Identifying these signs early can prevent further damage. If visible issues or ongoing vibration remain after basic checks, contacting a qualified technician is the safest next step.

Inspect Fans, Registers and Airflow
Airflow problems often cause uneven temperatures. Registers should be open and free from furniture or debris. Walking through the property to check vents can highlight blocked areas that restrict warm or cool air. The internal fan should also be running smoothly. If it appears damaged or unusually noisy, it may indicate a more serious fault.
