HELP!!! SWEATING TO DEATH IN FLORIDA ac not cooling house but does blow out cold air?

QUIT YELLING !!!

The house was built in the 40's so the insulation is probaly lacking and there is likely much air infiltration through cracks around the windows, etc..

If the humidity is very high, the ac must work much longer to bring the temperature down to a comfortable level.

The ac is supposed to drain water, that is the water removed from the air it is cooling. Moisture in the air must be cooled also and water takes much more energy to heat and cool than dry air.

Take a thermometer and measure the temperature of the air coming from the supply vent nearest the blower and measure the temperature where the return is being taken back to the blower unit. If the difference is between 17 and 20 degrees, the unit is working as well as can be expected and is simply too small to handle the current cooling load. If outside this range, you need to have the system serviced.

You can reduce the load with insulation, sealing cracks, putting shades on the windows and painting outside surfaces lighter colors. A white roof will reflect a lot of solar energy.

If you are sweating, take advantage of some evaporative cooling and sit in front of a fan. As the sweat evaporates it is releasing body heat into the air. Spraying an occasional mist of water on yourself while using a fan will create the same effect.

Did u kno and Pat from Ohio have a good point. And I'd surely investigate that possibility. In the mean time Has anyone including you and the tech you hired looked at the out door unit. See if you have cotton or willow wood lint covering the outside coil, clean it off. Better yet Wash out the out door coil with an water hose that delivers pressure in a stream but not so strong as to bend the fins. And do it reverse, I.E. the fans outside usually pull air over the coil and exhaust it out thew top (or side to side, front to back depending on make and model). Turn off the power and wash the coil with the pressure nozzle close but away from the coil fins if you see anything other than clear water comming out wash out the whole coil. Cut grass clippings and plastic bags are another thing that tend to play havoc with air flow outside.

After your sure the outdoor coil is "breathing" try your cooling again. I just have a suspission that its not all insulation or cracks in the floor Because Im thinking in Florida where its above 70 a lot of the time insects would be a problem and since you didnt mention this I dont believe it to be your major problem.

No I believe the teck was tired or inexpieranced and just looked the the coils and decided they were clean. If you get out dirty water washing it backwards this is the problem as it has cut your cooling capicaty thus making a longer run time to get to your set point temp. Also the refrigerant has not lost all of the heat within its capicaty because of blocked air flow OUT SIDE. Feel the smaller line and if its too hot to hold your hand on your outdoor unit deffinately needs cleaning or your fan motor there is not doing what it is suppose to. YOu mentioned the water dripping this make me think this is where you need to consentrate or at least for the short run confirm that their is not a problem there.

Also as a matter of fact if there is any history you know of on the AC system it may or may not apply to your current problem. You didnt mention any other history associated with the unit so I assume there is nothing else it could be. If you have more information about the history of the AC send it along I'll read it and send you back an opinion (worth about what you pay for it though).

You did not specify whether your AC is a window or split type. But whatever it is, evaporator fan motor must be the problem. Check the evaporator fan motor capacitor first if it is in good working condition. If your unit is a split ype, capacitor is most probably located in the PCB inside the evaporator unit. If it is a window type, you can easily spot where the capacitor is. Capacitor looks like a piece of round or oval shaped aluminum metal with electrical terminals on top. If the capacitor is good, then you have to check the fan motor itself. If the fan motor is good, check the speed relay in the PCB if it is making contact. You may also check the remote control. Sometimes the fan speed is set to low. If this is so, change the fan motor setting A good technician knows what to do in this kind of situation. Troubleshooting an AC involves several logical steps and I cannot specify what is the exact problem unless I see and check it personally. I just hope the tips above help you at least do the basic things. Placing an electric fan facing the AC unit will help push the hot air into the AC unit while you are waiting for the repairman.

Sounds like an insulation problem to me. Heat is a radiant form of energy. So, is sound..so if you can hear the sounds from outside pretty easily that means that the heat can transfer just as easily.

I'd suggest getting trims and sealings for your doors and windows. They're the most likely cause of your problem. If that doesn't work and you've tried to sure up the insulation in other parts of your home..buy a bigger AC unit.

The cool air is leaking out through every crack in your house and the AC is dripping water because the condenser is working like crazy trying to cool a building that is impossible to cool.

You need to insulate your house and seal up cracks in old window frames and stuff. You'll ave money in electric bills and will be much cooler.

Check it out,Run your blower ONLY for 30-45 minutes and turn cool off.Then put it back to cool and the fan to auto.

See if that helps.

cool in the am hot in pm dirty condenser coil water driping from air handler clogged evap coil clean both of them youll be cool ac tech should have caught both of them im an ac tech i do this for a living not like theses bozos

keep your curtains and blinds shut and add some insulation to attic take your showers at night and dont use your oven and shut off every thing electrical IE computers tvs during the day
