is auxiliary heat the same as emergency heat

These supplemental heating sources are things such as the electric resistance heating at the indoor unit, gas, oil or even hot-water back-up systems. The auxiliary heat will kick on if the heat pump needs additional heating capacity to meet your set temperature. The difference between auxiliary heat and emergency heat is simply the name. When you need heating or air conditioning repairs, maintenance or system replacements, you need a company you can count on for dependability and quality service. Switching to the emergency heat setting forces your heat pump to bypass the method it typically uses to produce warm air and instead rely solely on heat produced by the heat strip coils. The outlet temperature with and without Aux heat depends on outdoor temp, wattage of electric heat strips and CFM setting. The reason your thermostat has aux heat is that it indicates when gas or electric power has been triggered to help your heat pump reach a warm enough temperature when the weather outside is extremely cold. The thermostat will sense this and turn on electric heat strips automatically turning on the “AUX” heat light. Emergency heat is a mode the user manually selects if the unit is not providing any heat for some reason such as a malfunction. The difference in name "emergency heat" vs. "auxiliary heat" results from differences in needs based on your local environment. This is why it is only used in an emergency situation.

When a system is put on an emergency heat mode, the heat pump is shut off and completely bypassed. Please call to get service when this happens.
