why is my home airconditioning not cooling enough even when I already put it to 70 degrees?

Question

after an hour it still is 80 degrees, what causes this?

Answer 1

could be bad filters

Answer 2

When this happens the AC cooling energy (BTU's) is much less than the heat energy (BTU's) inside the house--cooking creates heat as does the heat coming from outside the house or apartment.. Even though the AC setting is 70 degrees it will take any AC unit some time belore it actually cools the room temperature down to the AC setting. If the room temp stays at 80 after another hour or two then something needs attention. If the AC was working well before, then it is possible that the air filter is clogged and needs cleaning or replacement. Also your AC unit may have lost some refrigerant due to a leak in the unit. You can usually change the filter easily but repairing a refigerant leak will require the services of a technician/repairman. If the AC unit was recently purchased and/or installed it is possible that its capacity (BTU's) is not adequate for the size of your room or house. In this case consult with a service person or company to replace the unit with one of adequate capacity.

i assume your ac was working fine yesterday, correct? and it's not today? well, something has gone wrong. i doubt if it is a refrigerant problem. more than likely it is an electrical issue. is the outside fan AND compressor coming on?

it is the first of the season so you will want to check and change your filter which should be done on a regular basis depending on type of filter used.

is there any indication that the indoor coil is icing up, (h2o on the floor)? then your evaporator, (indoor coil), is not exchanging heat due to dirt or a dirty filter.

as far as the outside unit goes, is the fan and compressor coming on? (also, check your outside coil, (condensor coil for ac), for dirt and clean with water. care should be taken not to bend the fins). well it almost doesnt matter because compressor will open on overload if the fan doesnt come on and overloads are typically internal auto reset and can take hours to close. typically you can expect a fan realy, contactor, or a fan capacitor to be at fault here.

many many things to consider, but i doubt if you have a refrigerant leak. BUT the only way to tell is to check the pressures and see.

more than likely you have an elictrical issue and a component has failed. BELIEVE ME, that's better than a "FREON" leak as everyone calls refrigerant, cause that typically may indicate a bad leaky evaperator. OUCH!

Answer 4

The most common reason for this is that your air conditioner is low on freon. If it has not been tested and serviced for more than a couple of years, this is most likely it. Another possibility is obstructions around the unit that prevent proper air circulation. Last, and least likely, is a problem with the calibration of the thermostat, but this is unlikely sice that would have shown up during heating season as well.

Answer 5

This use to happen with ours. It would just be caused from a dirty filter. Once you've checked that and either washed it (if it's a permanent one), or replaced if it's a disposal one, that should fix you up. If still not working, hose down the coils on the main unit. If these two fail to fix, then it's time to call a professional. Good Luck!!! Hope it's a simple fix!

Answer 6

Sammy has it precisely backwards as to which must be warm or chilly. it extremely is somewhat a threat which you will desire to envision fuses and/or circuit breakers. they could be placed in a field outdoors the domicile and additionally interior the domicile. now and returned the condensing unit fan is working however the compressor isn't. this could be by way of a minimum of something so hassle-free as a foul run capacitor. in case you alter the disposable air filter out month-to-month you will in all risk be ok. stable success.

Answer 7

if your upstairs its because your HOT air is still rising. if you not upstairs, windows are open or you should probably clean out your filter. cleaning out the filter even though it may not be the problem helps alot. if thats n ot the case then talk to a air conditioning company.

Answer 8

Either your condenser is shot or you're a little short on coolant. Call a pro, they don't sell Freon to us peons anymore and if that's what yours uses, you'll be outta luck.

Answer 9

Either your air conditioner isn't big enough or it needs to be recharged...the latter is most likely the case. Change your furnace filter too....

Answer 10

It may need freon and be sure to change your filters on it.
