Limit Switches

The limit switch on your air conditioning or heating system is the link between the blower on your air handler and the thermostat. When the thermostat senses that the desired indoor temperature has been reached, it stops the air conditioner from producing any more cold air or the furnace burner from generating flames and heat.  At that point, it’s important for the blower to stop functioning as well.

If it doesn’t, the  air conditioning or heater blower will continue to move uncooled or unheated air throughout your home. However, if the blower shuts off too soon, the cold or hot air that’s still being generated by the air conditioner or furnace won’t be able to circulate. So it’s essential that the blower be switched off at the same time the cold or hot air stops arriving. That’s exactly what the limit switch does.

The limit switch in your air conditioner or furnace plays a vital role in keeping your home comfortable and in allowing your HVAC system to function as efficiently as possible. If your HVAC system is shutting off too soon or not soon enough, it may be because of a broken limit switch. Sometimes, the system simply needs to be reset, something you can do with the help of your owner’s manual. However, if your limit switch is broken, you should contact a professional to take a look and determine if it needs to be replaced.
