Heating and cooling problems can affect comfort, energy use, and system reliability. This guide explains the most important things Bay Area property owners should know.
Dirty Filter or Airflow Restriction
Restricted airflow can cause temperature or pressure limits to shut equipment down before the thermostat is satisfied.
Thermostat Problems
Poor thermostat location, loose wiring, incorrect settings, or a failing control can create erratic cycles.
Electrical or Safety Controls
Capacitors, contactors, flame sensors, pressure switches, limit controls, and other components can interrupt operation when a fault occurs.
Refrigerant or Coil Problems
Cooling systems may cycle abnormally when coils freeze or refrigerant conditions are incorrect.
System Sizing
Oversized equipment may satisfy the thermostat too quickly, then restart soon after. A technician can determine whether the cause is maintenance, repair, controls, or design.
