A control unit controls your home’s indoor temperature. When it breaks down, you will not be able to regulate your HVAC system, and in turn, fail to keep your home’s indoor environment comfortable! Often, when a control unit breaks down, it becomes unresponsive, but it fails to detect and adjust to temperature swings as you had anticipated. Occasionally, it may fail to signal your HVAC unit to turn on as expected. In some cases, it would turn the HVAC unit on and won’t turn it off at all, then a control unit could break down because of a wiring defect that disrupts signal transmission between the control unit and your HVAC equipment. This could cause the plan to start and stop unnecessarily. This short-cycling causes temperature fluctuation inside your home, some rooms will not get conditioned air to heat or cool the room. Short cycling also strains the compressor and raises electricity bills, check your control unit’s calibration to ensure it is correct.

Check the wires that run from the control unit to the central AC and repair them if they are faulty. A control unit could also have lost its connection to the compressor when the fan is running. Therefore, the HVAC plan will not blow cool air from the vents. If you experience any of these complications, you need to call an HVAC supplier to repair your control unit, however better yet, troubleshoot your control unit and determine the best course of action.
