Do’s & Don’ts of Using Emergency Heat, Prior Lake, Minnesota

With frigid temperatures hitting Minnesota this winter, homeowners may be relying on their heating and cooling system’s emergency heat settings to stay comfortable indoors. However, this system is a backup heat source and should only be used in an emergency. To avoid sky-high utility bills and to keep your family safe in case of an outage, below is some information about emergency heat.


Use it for emergencies only.

If your primary system fails to warm your home at all, switching the emergency heat on will bypass the pump and turn on your secondary source. For example, your electric system could convert your air handler into a temporary furnace while your gas heat pump is malfunctioning.

Know how to turn it on.

heating and coolingEvery heating and cooling system is different, and so are the thermostats that control them. On many thermostats, it’s labeled as the auxiliary or aux heat setting. Familiarize yourself with your thermostat’s user manual to find the appropriate way to turn the emergency heat on, so you’re prepared for any unforeseen circumstances.


Turn it on if your primary heat source is working.

Some homeowners will turn on the emergency heat while their heat pump is working to give it a boost, unaware they’re switching to a new source entirely. Doing so can damage your entire heating and cooling system by using more energy, which may cause it to overheat. Additionally, the increased energy usage will drive up your utility bills.

Leave it on for a prolonged period.

Your emergency heat setting should only be used until your heating system can be repaired by a professional. Ideally, this is no more than a day or two. Using it for long periods will increase your utility bills and put your supplemental system under too much strain.
