For the winter months I would recommend Auto if you want the warm air to blow only when the system is running. If you want the warm air blowing non stop then I would recommend on. for my personal opinion I would suggest Auto. Just because it's more efficent and it does not bring in as much humidity.
use the lowest fan speed. Strange but true: a heat pump works most efficiently when set to a higher fan speed. Of course, high fan speeds can produce more ambient noise and air movement. Use the highest speed you're comfortable with, then dial in your preferred temperature setting (see #1).
"AUTO" is the more energy-efficient option, as it runs the fan only when heating or cooling is actively needed. "ON" keeps the fan running continuously, which can help with air circulation and filtration but may consume more energy.
Using the “Auto” Setting
This setting offers benefits including: Increased energy efficiency by running the fan only when needed. Extended filter life as the fan operates less frequently. Lower energy bills due to reduced electricity usage.
Lastly, while we do not recommend using “Auto” mode for the heating and cooling function, we do recommend using “Auto Fan” mode to control air circulation as it tends to be the most efficient setting for that function.
For winter heating, aim for the lowest comfortable setting, around 68-70°F when occupied. Recommended configuration includes: Set the system to “heat” or “auto” and increase the temperature to 68-70°F during occupied hours. Program the thermostat to lower temperatures to around 62-65°F when away or asleep.
Pros for “Auto”: If you set your furnace fan to “auto,” the fan will only run when the system tells it to in order to keep your home as warm as you want it based on your thermostat settings. This means it's consuming less energy than when it runs non-stop, which means lower furnace bills.
Which Thermostat Setting Is Best: On, Auto, or Circulate? Given the amount of money it costs in increased utility bills and filter purchases to keep your AC fan running constantly, most of the time, you'll want to keep the fan in the “auto” position.
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.
Should you use the auto function? No. The unit will decide whether to be in heating or cooling mode depending on the temperature in the room and the temperature you have it set to. Many factors such as the sun coming in a window could turn the unit to AC in the winter.
' To achieve an optimal balance between performance and energy usage, we recommend that you set your heat pump / air conditioner temperature between 23-26 degrees (cooling) in summer and 18-21 degrees (heating) in winter.
Keeping the fan on creates a more even distribution of heating and cooling, circulating the air if you have cold or hot spots in your house, like a bedroom above a garage. Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend it's lifespan.
During the winter months it is best to allow your heat pump to run at a lower fan setting and spread heat out more evenly over a longer period of time. The reason for this is two fold: Maintaining temperature over a longer period of time is more efficient than getting a room to temperature quickly.
The main benefit of setting the thermostat to 'Auto' is that it will result in more energy efficient usage. This is because the fan will run only when it's required.
best way to benefit from the heat pump is to use it for as much heating as it can handle. Try to keep doors open to rooms allowing the heat pump's heat to circulate as much as possible. Open the doors and turn up the fan. Use the “heat” or “cool” setting on the thermostat or control rather than the “auto”.
Since the AUTO setting means the fan is only engaged when the system is on, rather than constantly blowing, AUTO is the most energy-efficient option between the two settings. This means you'll be using less energy and saving money on your electric bill by using the AUTO setting.
This is the setting used to move air in your application all the time instead of when the system is running. The Circ (Circulate) position, if available, will run the fan approximately 35% of the time, roughly 20 minutes each hour, minus any time the fan is already running with the heating or cooling system.
The heater might blow cold air rather than warm if the gas line supply has been turned off. This usually happens when something goes wrong with the heater, and it breaks. For example, maybe there was a problem with a gas valve, the gas supply pipe, or something else in your furnace broke down.
In most cases, auto is the best option, but there are instances where you may want to use the on setting or a combination of both called circulate. There is no right or wrong answer, but by understanding the pros and cons of each setting, you can use them more efficiently for your home.
Potential Fan Motor Wear: Your furnace fan's motor is not designed for constant use. Running it continuously may lead to more frequent maintenance and repair needs. However, the added comfort and air quality benefits often outweigh these concerns.
Temperature Settings: Keep your home between 68°F to 72°F during the day and lower to 62°F to 66°F at night or when away. Mode Selection: Use Heat mode over Auto to avoid unnecessary energy use and system strain.
Once you understand how a heat pump operates, we can explore some possible reasons why a heat pump might blow cold air, such as incorrect thermostat settings, clogged air filters, a dirty outdoor unit, or issues with the reversing valve.
Set it and forget it. Heat pumps operate most efficiently when holding a steady temperature. Turning heat pumps down when you're away or asleep may actually use more energy than leaving them on. The reason is that they have to work harder to come back to the desired temperature than they do to maintain it.
