my ac unit is not cooling correctly there is a 6 degree difference between upstairs & downstairs how do i fix?

Answer 1

Cooler downstairs I assume...

It takes a lot of power to push that heay cold air up stairs. Try closing all the registers on the ground floor. That will force the coolair up there. Don't worry, plenty of cool air will spill down the stairs and into the lower area.

Answer 2

This happens a lot in two-story older homes. The roof may need to be replaced. An old roof allows too much heat to pool in the attic space. Also a poorly insulated attic allows this heat to move into the second floor, heating it more than the lower floor. Also, the location of the thermostat is usually on the first floor, where it is cooler, so the upstairs stays warmer since hot air always rises.

There are a few things you can try:

Put in a second thermostat or multiple thermostats to control the temperature from whatever room you are in. We have put one downstairs for during the day and one in the bedroom for at night.

Install dampers in your ductwork that will force more of the cool air to the second floor. This is probably of menial value since the cold air will roll downstairs anyway.

Install new insulation in the attic, newer windows, and if your roof is old, re-roof your house. The newer roofs have vents and air gaps built in that allow less heat into the attic and promote air circulation in the attic which prevents heat from seeping to the second floor.

Answer 3

Hot air rises, cold air sinks. So a 6 degree differential can be expected. When you're trying to cool your home, close the downstairs registers and open the upstairs registers to force all the cols air upstairs. It will sink and cool the downstairs also, thereby leveling out your temperature differential. The A/C unit will shut off automatically when the setting on the thermostat is satisfied.

Answer 4

Your thermostat is probably located downstairs, right? It is responding to the temp downstairs not upstairs. You might want to consider a separate AC unit for upstairs if there is that much difference. You could also set your thermostat lower to keep the upstairs cooler than it is, but it would make the downstairs cooler, too.

Answer 5

I had a similar difficulty. a superb pal of ours owns an a/c organization, so I were given suited suggestion. in the starting up, he made particular that the vents downstairs were not totally open, and that the upstairs vents were totally open. because the blower is on the first floor, rooms closest to the blower get carry of extra air, rooms farther away get carry of a lot less so the vents could accommodate for that. perhaps it really is part of your difficulty. It did not make a huge difference in our abode, the blower replaced into too small to manage the upstairs. We ended up having to purchase a 1/2 ton more beneficial blower (air handler), and now it really is tremendous, electric powered costs are down, too. He did say that there replaced right into a booster accessible to help blow the air upstairs through the duct equipment, ours replaced into old, so we opted for the hot blower. solid success, desire it really is merely the vents. I merely remembered, our air handler had a leak from the unit to the position it meets the ceiling, air replaced into leaking out at contemporary on the unit. See in case you could sense any chilly air popping out from the blower itself, it would want to not were sealed wisely.

Answer 6

I don't believe there's much you can do about that. Warm air rises and it is usually warmer upstairs than downstairs. The only thing I can think of is using a ceiling fan or even a regular fan to get more air circulation.

Answer 7

Ceiling fans or anti gravity. Hot air is less dense therefore it rises cold air is more dense therefore it falls. If you are serious multiple temperature sensors and automatic dampners will make sure your home is equally cooled or if you want to save several thousands of dollars, close the downstairs dampners enough to balance the temperature of the two floors.

Answer 8

Hi Hot one,
Make sure your ac units' filter screen is clean. Assure that the ac unit is on it's own circuit and not sharing power. It may be to old
and out of freon.
Love and blessings,

Answer 9

Switch the fan setting from fan auto to fan on. This will keep the air circulating in between the A/C cycles.

Answer 10

turn the fan from "Auto" to "On." I have the same problem in my house and this was the advice from a HVAC tech. It worked wonders very cheaply.
