When should AUX heat come on?
Aux heat should only kick on when the heat pump can’t produce enough heat to warm your home on its own. This is typically caused by one of three factors: when it’s below 35° outside, you’re trying to heat your home by 3° or more, or your heat pump is in defrost mode.
Do heat pumps work below 20 degrees?
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Why is my heat blowing cold air?
Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off so that the heat exchanger does not crack.
Should fan be on auto or on for heat?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.

Although it is possible for a gas furnace to either catch fire or explode, it’s highly unlikely.If you’ve got a good furnace and take care of it, you won’t have to worry about explosions or fires.
What is the burning smell when I turn on the heat?
Burning Dust Smell
If many months have passed since its last use, dust and other types of debris may collect on the burners, heat exchangers, air ducts and other components of the heating unit. When you turn the furnace on, this dust and debris burn off, releasing a smoky odor.
How do furnace fires start?
Yes, a furnace can catch fire.
The following are reasons your furnace can catch fire: Your furnace’s air filter is blocked. Your furnace’s gas pressure is too high. There is a crack in your furnace’s heat exchanger.
When should you turn emergency heat off?
Make sure emergency heating is turned off after your heat pump is fixed. If you run into any heat pump issues make sure you contact Flame Heating and Cooling as soon as possible so you can get your heat pump fixed and save money by not having your emergency heat on for an extended period of time.
How cold can a heat pump get your house?
If your system is not cooling correctly, the heat pump can run all day trying unsuccessfully to reach the 70-degree temperature. Your heat pump temperature shouldn’t be any higher than 80 degrees Fahrenheit (27 degrees Celsius) during the summer.
Why are heat pumps not used in northern states?
But they’re not very common in the North, and there is a very good reason for that. Heat pumps are known to not work well in colder climates during the winter months. The way they’re built makes it so they’re more efficient in climates where the temperatures don’t drop below freezing.
Why won’t my furnace shut off?
If it’s cold, that means that your furnace is not running but the air handler is still blowing air.If the air that the furnace is blowing is hot, that means that the furnace burners aren’t turning off. Two very common causes are that the thermostat is set too high, or the filters being dirty.
