Fan Hold. Creating a Fan Hold will allow your
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.
It varies with the thermostat, but the On/Auto switch usually controls the fan only. Having it to on will recirculate their air, but will have little to no effect on the temperature. Generally all it does is waste electricity and adds wear and tear on your system.
it is actually highly recommended to run fan for 20-30 mins per hour for air circulation, keep house equally cool/warm .
By pressing “Hold”, your thermostat will lock in the temperature it's currently at until you change it again. When you are ready for your normal schedule to resume, simply press the “Run” button and return to your typical programming.
Using the “hold” function on your system means you can suspend the program if you'll be away from home for a while, such as while you're on vacation. This means you can tell your HVAC to stay put at a specific temperature to keep your pipes from freezing in winter but as warm as you want it to be for comfort.
Both features can allow you to save money on your energy bill. For example, the “hold” button can help you set the temperature to an energy-efficient level if you're out of the house for a few hours. On the other hand, the “run” button allows you to ensure that your scheduled temperatures remain energy-efficient.
Fan Hold. Creating a Fan Hold will allow your ecobee to run the fan for a set period or indefinitely. On the ecobee Thermostat. Go to Main Menu > Fan. > On then select the desired runtime from the drop-down menu.
To strike a balance between comfort and efficiency, running the fan for 15-20 minutes per hour is typically recommended. However, in certain situations, longer fan run times may be necessary, particularly during hot and humid weather or for enhanced air filtration and ventilation.
Yes, it's absolutely useless. There's no point in wearing out your fans for nothing even if they can last years like that. Set a custom fan curve, it'll be way more efficient than running them at 100%. And you can have the best fans in the world, with just the noise of the air flow, it'll be noisy at 100%...
AUTO is significantly more energy efficient between the two modes since the fan is only running when your AC is going through its cooling cycle. This takes less power, which is more budget-friendly, with some estimates showing you can save as much as $50 per month just by keeping your AC on AUTO.
If your system's fan is running without a break, the distribution of cool or warm air in your home will be more even. This lessens the likelihood of rooms without a thermostat being too cold or too hot.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
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.
Answer: You can— and should— run your A/C and ceiling fan together. Doing so can help lower your cooling costs each month, but only if you're using them right.
Choose "AUTO" for energy savings and "ON" if you want constant air circulation or improved air filtration. Temperatures can soar or plummet depending on the time of year. Throughout the year, it is important to have reliable heating and cooling systems in order to keep your home supplied with cool or warm air.
The fan will constantly blow air into your room if you have the thermostat turned “ON.” If it is on “AUTO,” it will only turn the fan on when heated air needs distribution. So yes, running HVAC continuously throughout the day and night is perfectly safe!
Optimizing Fan Speed Summary
For your furnace and AC to work properly, and keep humidity in check, your system first needs to be sized correctly. Second, it needs to be installed correctly, and fan speeds need to be set to deliver CFMs between 350 and 400 CFM/ton of cooling.
The average unit has a 500 watt fan, which uses almost as much energy over the course of the year as a refrigerator, resulting in a $50/month bill. During the summer months, the ducts in your attic and close to your walls can fill with warm air, resulting in the fan blowing hot air into your house.
If you own a programmable or Wi-Fi thermostat, keep in mind that a “temporary” hold is supposed to continue your typical schedule at the next programmed time. So you should try the “permanent” or “vacation” hold setting when going on vacation to make sure your preferred temperature sticks.
Your blower motor circulates air through the furnace and can provide uniform temperatures. Many people leave their HVAC fan on all day, while others opt for two to three cycles per hour, ranging from ten to 25 minutes, depending on how close to heating or cooling temperatures they are.
Performance vs Noise
For optimal performance, higher fan speeds are ideal. If your focus is on low noise, however, you can consider setting your fan speeds lower. As a low noise enthusiast, you can even consider running your case fans at 20% until the CPU reaches a temperature of 60°C (as an example).
This means, that in turn, when your setting is turned on auto less electricity is used. When your fan and air conditioner are running all the time, more electricity is produced. All in all, it is better to leave your air conditioner's fan on auto, instead of “On” at all times.
“Hold” on a thermostat will lock the thermostat at a certain temperature. Even if you have preprogrammed temperatures for different days and times, pressing the “Hold” button will overrun those settings.
The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous.
