We just had 2 mini split air conditioners put in our home, which previously did not have air conditioning. We have ceiling fans in every room and I am wondering how to use the fans in conjunction with the air conditioners that are at ceiling level. Should the fans be on summer mode? What speed is good to use to enhance the distribution of the cool air in the rooms?
We usually keep the fans on high to keep the air moving, but with the air conditioners, I am not sure if the warm air near the ceiling is making the compressors work more.
Any advice out there?
As for direction / speed a piece I did on that - http://thehtrc.com/2014/faq-ceiling-fan-direction-summer-winter which goes from basics to common exceptions
The biggest things though to keep in mind: if your not in the room it does no good to have it on. The next is just like ducted, the unit pushes out the conditioned air which creates the mixing, it isn't up to the ceiling fan to do that while it is running
Thank you. Good information about the ceiling fans.
Using a ceiling fan as part of a team to bring your maximum home cooling comfort. Adding a ceiling fan can allow you to actually turn up the thermostat, saving you energy and money.
Another way to conserve energy and cost is to make sure your ceiling fan is only on when the room is occupied.
Running a ceiling fan actually heats up air. Allison Bailes has some great articles on it. I would set fans to slowest speed if you are having issues with the mini splits distributing air throughout the room. Otherwise you might be making them work harder depending on where they draw in the return air. Most units draw return air in the top and conditioned supply air out the bottom. You could be making it hard on the system by mixing the air w a fan. Try turning the fans off for a day and see if that helps.
