If the digital numbers represent the temperature then a lower number will make it colder for cooling. If you have a temperature dial with numbers 1-10 for cooling only , a higher number is colder.
Having the fan running between cooling cycles will cause a wet evaporator to raise the humidity somewhat until the coil dries off. Hard to say if extra circulation is still a benefit when you consider giving back a little humidity to the space.
@@tradesmanmechanicalservice1668 I said that because we are defeating the purpose of the coil drainage by reintroducing that water vapor off of the coils back into our homes that the HVAC system just worked on capturing and draining.
Should I keep the fan running during the winter months on my furnace that is located in the Non climate controlled attic? I am concerned it might force some cold air through the system.
so what yall trying to say is that" auto " means if I set it to 68 it'll stop when it does reach 68. then when the temperature goes up its turn back on?
Does it use much energy if you are just using the fan all time with out heating/cooling ? It gets pretty cold at night by the river where i live and i open windows during the night and close them in the morning. Then i just use the FAN ON without AC in the summer.
How does the fan turn on automatically? I am sick and I want to have my room cold so I want to open my window but don’t want to cost my mom money. Does the intake suck the cold air and let’s the heating and cooling know it needs to be turned on? Or should I just close all my vents?
I am so confused I live in an apartment and I have electric heat that’s controlled by a thermostat and I have no idea how to work it . I believe it’s on because I hear clicking and it’s warmer but I don’t know how to regulate the temperature and I’d it normal that the heat is so dry ? My nose and throat are so dry since it’s been on HELP
Temp is my area is finally going up into the high 90’s and my fan turned on on it’s own. It is set to auto but it won’t turn off. I don’t know how to do that. Only options is auto or on. Ac and heater are off. What do I do?
Soooo, it depends on what you want to accomplish. Using auto will run less and be cheaper but will start and stop more often and possibly wear out the capacitor if you have one on your motor. Using Fan ON will use more electricity and may add slightly to wear and tear on the motor bearings, but the extra comfort you should end up with might be worth it to have less hot or cold spots due to better circulation.
@@tradesmanmechanicalservice1668 Please do a Trane thermostat video. I believe it's an Xl 850.. I was always taught to run on auto and the installation guys set it to cooling. 12K for a new unit and the company had to read a manual to program the thermostat in my face. 🤔
My 18 year old Lennox Gas Furnace functioning perfectly except that the "Fan On" option is not working. Can you please advise about what repair is required?
Trill Monger circulate means: fan runs a certain amount per hour about 35% of the time not including ac or heat operation. Do not use this setting because your fan motor has enough stress on it in auto let alone coming on and off 3 or 4 times per hour
Alex Golestani r u sure? I don’t think that’s correct. Circulate is a much economic option than on and certainly better than auto to keep air moving around.
ERIT DJz sorry about the long reply time, I had a Honeywell utilitypro t-stat and it had circulate. It runs the fan at random periods. About 35% of the time. It runs the fan so often that it could put a lot more wear on the blower motor one of the reasons to keep fan in on is to avoid the wear on that motor circulate option triples that wear. Newer ac units/ furnaces have such high efficiency fan motors that leaving it in on will actually save you money because the heating/ air conditioner will cycle less.
I have noticed that having fan on only is triggering my asthma is that possible does the air quality change with fan on only? My thermostat is changing on its own I set it to auto then it changes on its own to fan my house starts feeling hot and I wake up needing my inhaler could fan change the air to trigger my asthma
I have a Honeywell thermostat it says heat but still blowing out cold air i set the temperature to a high heat setting but the thermostat drops back down to a very low temperature
Question, so I have the Honeywell T6 and 2 weeks ago the fine had to be replacement. It was set on Cool, "Fan On" and I do believe this is the reason the fan wear out. Currently it winter, and its on Heat, "Fan Auto", The system is cutting on and off as its suppose to. So, I am wondering that is okay I keep it on: Heat, "Fan Auto", I saw where you stated it may cause damage to the capacitor. So exactly what is the purpose of the capacitor and do I have my thermostat on the right temperature
Hmm not really sure what is going on with mine. The fan is set to auto, heat is on but this can change cycles to aux, aux heat, off, em when needed. The blower is always on even though the fan is in auto. It also shows “heat” when the thermostat is set 1 degree lower than the current in house tempature. The blower isn’t actually pumping heat “at least it doesn’t feel hot” it feels cool
It looks like your thermostat has an emergency heat and aux setting which represents controlling a heat pump or a secondary heating unit for backup. This creates a whole different scenario as to why your fan may be running continuous when set to auto. Not sur I can offer much help without some specific diagnostics.
My fan won’t turned off even when temperature has reached the wanted temp. Any idea how to change it so it will turn off ? It’s set to auto right now at 70 deg
I would check the furnace to see if there is a fan control that may be set to run the fan. Most electric furnaces will have this. If not the you may need to replace the thermostat ot verify the wiring connections. Hope this helps.
No it won’t damage anything unless she does it every 5-10 minutes- if she turns it on for 2 hr then turned it off for a hour - it won’t damage anything
I have a proselect the fan wont come on manually in on position just auto. Im assuming whoever hooked it up did it wrong what wire and where to hook it ??
My guess is that you may be short one wire. If you have heat and air you need a minimum of 4 wires. ( RWYG ) 5 if your thermostat needs a common. ( RWYGC )
You can if you wish to have air circulating all the time. When you have it set to cool, the thermostat will cycle the compressor on and off to maintain the set temperature. Having the fan on with the cool setting will simple keep air moving between when the compressor cycles on and off. Hope that helps you.
Hey can you help me out with a question? If I have my cooling coils off and my fan in auto, will it still run to cool until the temperature I have set? Just wondering whether I have to turn it off manually every time I desire it to stop. Thanks.
The fan control setting is either "on" all the time or set to "auto" where it will cycle on and off together with the heating or cooling. If you have your system selector switch "Heat, Off, Cool" in the off position you will not get any cooling or heating.
If one is pulling cooler air from the basement upward there's no need to worry about the humidity that comes with it. That air begins the evaporation process the instant it hit the blowing air. I'm not even a plumber. I'm a brain surgeon... Just kidding. This is a very good video.
My opinion and experince i set my thermostat ON with in 3 years i hear loud noise from the fan motor i think if the fan on all time there a time the motor wontlast or wornout
You are correct in that the motor bearings can wear out sooner with continuous run. But that may be the cost of having better comfort with air distribution over those 3 years.
The fan selector when switched to the off position will only allow fan operation during a heating or cooling cycle. The only way to be sure the fan will never come on would be to turn the system off entirely.
@@tradesmanmechanicalservice1668 thank you for answering so quickly! I've been in my small apartment for 3 years and I got a bill for 97 dollars. I've been keeping it at 68 because it's been hot at my normal 71 and my last bill came in $20 higher than normal. It was like it just kept going but I checked that it was on auto not fan. I dont know what to do. Should I call my landlord and ask him to have someone check the vents or furnace or call Columbia gas and see what's up?

The circulate is a great option that some thermostat have. Simmilar to the "fan on" option, this option may have timed cycles to run the fan intermittently.
When your thermostat is set to fan "on" that forces the furnace or air handler blower fan to run continuously for the sake of circulating the air between cooling or heating cycles. The outdoor unit (condenser) should cycle on and off as required to cool your home. When it cycles OFF you should hear the unit get quiet, and see the fan turn OFF as well. Hope that helps Jeff.
I'm always wondering if the vent at the basement should be closed or left open. The vent in the basement of my house is located in the ceiling. And it is installed on the ground on the 1, 2 floor. My house is two years old and the basement is unfinished so no one is using it. I keep all vents in the basement closed all year round. Even if the air conditioner temperature is set to 73 in summer and the fan is set to ON, the basement is too cold, the first floor is cool, but the second floor is hot. The ventilation fan is turned on in winter and off in summer. What should I do?
Closing all the vents in the basement is not the best solution since it reduces the total airflow thought the a/c cooling coil (evaporator) thus affecting humidity removal and overall comfort. It appears that you do not have sufficient ducting to your second floor including return air runs. This unfortunately very common in a lot of homes. The easier partial fix is to introduce more return air from the basement.
The Auto/On control has no effect on how the compressor cycles. The control allows the fan that circulated the air (blower fan) to either cycle with the condenser, or stay running between cooling cycles.
Not sure how to answer you. If you are looking to save on electricity, running the fan continuous ("on") will use more electricity but will possibly offer more comfort in areas that take longer to cool.
Tradesman Mechanical Services Ltd. sorry I’m not communicating well. If thermo is set on 80 and fan auto , on a very hot NYC day my AC unit will cycle on and off about every 1/2 hour to maintain 80*. Wondering if that is truly efficient, as opposed to setting thermostat to 72* and having it take longer to heat back up?
I am still not quite getting the drift of your situation. Air conditioning is best left to cycle within a narrow range ( "set it and forget it" ) is what we recommend. This way the unit will have a chance to more effectively remove moisture which adds to your comfort level. Air conditioning means Cooling AND Removing Moisture. Put it this way: It may only take 10 minutes to cool down a space by 2 degrees if it has been left to cycle. Then say you went away for the weekend and turned the a/c off to save energy. Upon turning it on, it would then take much longer ( probably 2-3 hours or more) to drop the temperature by those first 2 degrees since the dehumidifying component is more work that takes priority during a longer recovery cycle.
Forget power usage, that's ubsurd to run fan constantly unless heating or cooling is turned off. Certain times like spring or fall but never when it's extremely hot or cold. I guess common sense isn't common 🤷 😕 🙄

Thank you I am going to turn the fan on For my furnace during the summer I appreciate it
I like mine at 42F in the winter and 55F in the summer. We reptiles like it a bit kewl!!
Thank you! Does it impacts the life of the fan motor? Is running 24/7 non stop an issue.
Thank you I always wondered about that
Thank you very much you explained that very well. I will now switch mine to fan.,
Does using the fan mode increases much the energy consumption?
Older furnaces do not have a fan delay in the design to allow the heat to build up before fan operation.
If the digital numbers represent the temperature then a lower number will make it colder for cooling. If you have a temperature dial with numbers 1-10 for cooling only , a higher number is colder.
I was told the fan on will raise the humidity in your home when running AC, and to only use the fan for heat.

I would set my fan to on all the time speed will be high because I like white noise, and I set my heater to 55 and air conditioning to 60.
If you leave it on in the summer you will be blowing air across a wet coil which will make the home more humid......
