My PAC CN120E was working fine until the outlet that is above it started to smoke. I plugged it into another outlet and red lights came on but quickly disappeared. Can you advise if the unit is blown out,...


I cannot tell from which country or area of the world you are, but in the USA, your 12,000 btu a/c unit would take a special plug and electrical circuit in many homes or apartment, because it is so large.

Today, most circuits are protected with a 15 amp circuit breaker, which can usually handle only a 5,000. or 6,000 btu unit. The next size up it often a 7,500 unit, and that is a lot for a 15 amp circuit .Some older homes have a 20 amp circuit breaker, which can handle up to a 8,000 btu a/c.
Before you start a fire in your house, have an electrician check all this, and see what is going on.
One reason I am talking about such small a/c units it that usually, household electrical circuits have other loads on them besides the a/c.
Be blessed.

My Continental Portable Air Conditioner only blows partially cool air and will not cool my house. I am I just expecting too much? It seems like it needs freon or something like that.


Unless your home is less than 400 square feet, total. You are expecting to much. As the maximum cooling output is only 9800 Btu's These unit's despite being portable, they are only considered as room air conditioners, because of the low Btu output. Any more than 400 and maybe 450 square, it's a struggle for the unit to cool any more than that. It just simply can not do it. Freon ( which has been banded by the EPA) wouldn't help at all.

The best option for you, is to place the unit in a room you spend most of your time in and close the doors to that room, so that it will stay really cool and the AC unit won't struggle.

I'm really sorry. I wish I had better news for you.

I have an older 8000 btu unit - i have no manual. its 98 outside - when i start up this unit , should i have it on hi- med - or lo ? if i run it too hard will i freeze it up?


If everything is clean and the unit is properly charged with freon then it should not freeze up and I would start it anywhere you want to as that just controls the fan speed. It's108 here. Best of luck and thank you.

I live in a very small one room studio,and have a comfort aire window unit...air and heat.The heat works real well,but in the spring and summer,I would set the unit on the coldest setting.I can hear the...


Lets look at the output of the system first. Take your square footage of the area you are trying to condition and times it by 15. We try to get 15 Btu's per square foot of air conditioning. If your area is say 10 by 15, you have 150 square feet; times it by 15 = 2250 Btu unit is required. If you have a 5,000 Btu unit, it should be more than enough to cool the room. If this is correct, the problem may be because you have the unit set for Dry. In Dry mode, the compressor will cycle less frequently than if on Cool. If in fact the unit is on Cool, you may need to lower the temperature setting to fool the sensor from turning off the compressor prematurly. If you still can't cool the area, your unit has an issue with either refrigeration or air circulation and will need to be serviced.

My 30,000 btu Blue Flame gas wall heater wont stay lit, pilot light stays lit but the blue flame went out and had smell of gas I shut off the gas supply but, dont know what is the problem thanks, marty


you could have a overdraft problem causing your flame to go out. check your draft setting at the burner and make sure it's not open too wide. If it is, simply close it it slowly and make sure that the flame remains totally blue.

I need to know the seer number for an air handler. I'd


On the air handler take the top panel off, look to the left on the inside, this will give you general information on the unit on a stampede plate. This will
give you the date of manufactuer as well.

On the outdoor unit, there is a stamped plate on the
condensing unit. Should have year of manufactuer, it
should also say how many pounds of freon should be
in it. The Model number is what you need to know
to find out how big it is.

024=24,000 BTU= 2ton unit
030=30,000 BTU=2 1/2ton
036=36,000 BTU=3ton
040=40,000BTU= 3 1/2ton
and so on.

My guess is that it is an older unit and since I have
been installling units since 1995 I have only known
any older units to be at least a 10 SEER and no more.
