Explain set it. Generally there is a switch on the fan to reverse, are you attempting reversing by that switch or a wired in wall switch? If it runs in one direction it will run in the other. Something in the control is broken or not wired correctly.

How to cool big home with small air conditioner(s)


A lot of people have only one or two rooms that can take an air conditioner in the window. Often times, the air conditioner is also rated at a cooling power that would make you believe that there is no way that it can to cool the whole house/apartment. You can crank it to the max to try to cool as much as possible, but then this makes one room too cold and the others still stay too hot. You can try blasting the cool air down a hallway with a fan on maximum speed, but that only works so well. And, it's noisy, too. Well, I have two 260 sqr ft rated room air conditioners and I am cooling 2000 sqr feet of house to a comfortable 72 degrees in all rooms and it's been 95 outside all day. How to do it?

The trick is setting up your home to take advantage of laminar air flow. Set your air conditioner to say 68 degrees and start it in the middle of the morning before it feels hot outside. Put the AC deflectors pointing downward and towards the door. Put fans in the doorways pointing out of the rooms that have the AC. Point them level to the floor (not up) and put a fan to one side near the end of long hallways. Set the fans on the lowest power setting (not high). If the hallway branches out into a bigger room, put a fan in the room that is blowing across at a right angle to the entry, pointing the air flow parallel to the wall. This will circulate the cool air around the room. Keep the fans on low and pointed parallel to the floor, not up!

What you have created is a re-circulating air flow system, much like the North Atlantic Current that moderates the temperatures of Europe. You can check this by taking a tissue paper and holding it up to the top of the doorway. The air flow should be pushing the tissue away from the room without the AC and toward the room with the AC. This happens because the warmest air will be toward the ceiling and you want that warm air to make its way across the ceilings and back to the room with the AC, so that it can be cooled again. The cooled air from the AC will sink to the floor and the fans will gently push the air out of the room with the AC. It will stay low and travel along the floor in the opposite direction and into the warmer rooms. If you crank your fans up, you will create turbulent flow and that will not cool your house as efficiently as will laminar flow. Monitor the outside temperature and when it gets cooler outside by a few degrees, turn the AC to fan for about 10 minutes to eek out the last of the cooling. Then open the windows for the night to take advantage of the free cooling that nature provides. That's it! Enjoy the summer!

CEILING FAN w/remote. It worked until removed to paint. When it was reinstalled the speed is backwards (high for low, no med, low for high) & lights do not work. The re installer is not an electrician,...


There should be a small switch or a cord (tied to a switch) that changed the direction of flow. The reason for that is because you want the fan to move air downward CCW in the summer and upward CW in the winter.

My car when i'am driveing during at noon not coming more cool , but in th night alettel good but not 100% ,,, what i have to look


Hi, sounds as though you have a small leak in the unit. When its night its cooler outside, so it will blow cooler. The warmer it gets, the less it will cool. You can raise the hood. Start the car and set the brake. Have someone with you when you do this. Stand and look at the engine. Have them turn the a.c on cool high. You will see and hear the compressor come on, the clutch on the pump. Your fan bely wraps around it. When its on, if you see it go on and then off and back on and off, this is telling the compressor its low on charge, and needs to have some freon in it. If its a newer auto, you can buy a charging kit at any auto store, and it will tell you how. If you are un sure, stop by a auto repair and have them top it off. I am sure this is your problem.

How to set humidistat for different seasons.


Vick, depending on the season and the humidity level in your home, is what determines the setting. For example, in the winter you want to maintain at least a 40% humidity level in your home. It will feel more comfortable, the heat will feel warmer and it will help keep static electricity at bay. In the Summer, you'll want to remove as much humidity as possible, as this will make the air feel cooler. If you have ceiling fans in you home, run them Clockwise at the highest speed you can tolerate. The more wind chill you generate, the cooler the air will feel and you won't have to set your AC at a lower temperature. Thereby, saving money. In the winter, run the ceiling fans Counterclockwise on the lowest speed. This will take the heat off the ceiling, wash the walls and bring it back down.

Clockwise and Counterclockwise are determined by looking up at the fan blades. Also, reversible ceiling fans have a switch on the side (where the pull chain is located). Generally, switch-up is Counterclockwise and switch down is Clockwise.

Hope this helps you to keep your home comfortable year round.

Heat temperature issues with Goodman GMP 100-4 furnace


69,000 btuh is adequate for a 12-1400 square foot house.
Otherwise, your thermostat simply tells the furnace to cycle on/off.
If it calls for heat and does not come on, the problem is with switches and relays within the furnace.
Your setting the temp higher only causes the other parts to keep trying until they finally light and heat.
This is based on your information saying it will cycle on and blow cool air--not hot air.
You will have several temperature variations from floor to ceiling.
You probably have ceiling vents as well.
You need a technician to verify the rollout switches, fan relay, inducer fan etc. if the furnace is not firing everytime you call for heat.

Compressor fan not running


Does it look like the coils are frosting over? Is it steaming? Keep watching, after about 30 min does the fan come back on?

If yes to any/all the above then the unit is probably in defrost mode and yes the fan will stop blowing during that time, but restart when the unit goes back into regular heat mode.

During this time you will likely notice warmer heat from the vents than normal and the "AUX or EM HEAT" light will be on.

That is your backup heat system. It should automatically come on during a defrost cycle.
