Question about Heating & Cooling

Open Question

Great site. I have a Simplicity SPAC 8499-5 Portable Air Conditioner and it was working fine up until yesterday (~2 years old). The unit is running and the fan operational but while the green light for Cool/Dry is illuminated that actually cooling unit for the air conditioner is not kicking in. The system is just blowing air (like in Fan) mode. I have checked the water reservoir and it is empty and placed properly in the unit so the switch is engaged but no AC.

It could be as simple as being low on refrigerant. Depends on how expensive the unit is if its worth recharging and how big the unit is. Some small units will need to have a recharge point fitted which cost more of course.

A few basic principles for air conditioner troubleshooting. For both central home air conditioner or window air conditioner, the first thing to check is whether the unit is getting proper power. If the unit uses 220 volt power be sure that the proper voltage is getting to the unit. Same for 110 volt units. A voltage meter can be used to assure that the voltage is correct.

For window air conditioning units the voltage can also be checked before and after the thermostat. If voltage is being supplied to the thermostat but not from it then the thermostat probably needs replaced. This is a fairly common problem. Another place to check is the fan motor voltage. The fan on window air conditioners runs both the indoor blower and the condenser fan. If that motor fails than the compressor may run for a short time, but will overheat and shut off. Continued operation like this will result in compressor failure. This motor can be economically replaced for larger window air conditioners, but for smaller ones the cost of replacement will be more than a new unit.

Central air conditioners for the home are more complex and there are more things that can go wrong. As with the window air conditioner the thermostat can also be a problem. The central air conditioner thermostat will only have 24 volts going to it. So don't look for high voltage there. Some units the voltage will be coming from the outdoor unit and others the voltage will be supplied by the indoor air handler or furnace. Most home central air conditioning will be supplied by the indoor air handler or the furnace. If the air conditioner is for cooling only the unit will usually have only two wires going to the condenser unit. Make sure that you have 24 volts across those wires.

The next thing to check will be the indoor blower. If your thermostat is calling for cooling then the indoor blower should be running. If there is no air moving across the indoor cooling coil then you will soon have a big block of ice formed on the coil. This can happen for a few reasons. The indoor blower is not working, the air flow is restricted and not allowing air to move across the coil. A clogged air filter would also do this. Or the outdoor condenser unit has lost the charge of refrigerant.

Finally and worst of all is when you have a complete compressor failure. Often when this happens the compressor will "lock up" or not be able to turn when power is supplied to it. Overheating or lack of lubrication are usually the main causes of compressor failure. Overheating can be caused by the outdoor coil around the compressor getting clogged with dirt, leaves, or grass. Loss of the refrigerant charge will also cause the compressor to overheat. It is the cool return gas coming back to the compressor that helps to keep it from overheating.

As you can see there are many things that can go wrong with an air conditioner and I have not come close to exhausting the possibilities here. I have just touched on the most common problems in a very basic way.
There are some basic trouble shooting things that can be done very easily. Most problems are above out of the range of comfort for many homeowners and professional help should be consulted before any attempt is made at repairs. Remember also, that the release of refrigerant gases into the atmosphere is a federal offense in the
US. Proper care must always be taken to minimize the release of any gases. A license is also required to handle refrigerants. Make sure that the professional you call has the proper certifications to handle refrigerants properly.

You may need to reset the unit, if you did not turn it OFF & unplug it when you drained the tanks
To reset the units electronics, turn the unit OFF and unplug it for 15 minutes. After the time has elapsed, plug the unit in & turn it ON. The electronics should have reset and reverted back to the original factory settings. If so, you can adjust the settings to where you like.

Hope this helped you & thanks for choosing FixYa.

Cooloing is not coming down from room temperature


The unit needs service. Call a technician! You can:
Check your air filters
Clean outdoor coil by turning off all power at breakers and tstat, clean o.d. coil with water hose
Inspect indoor coil (if you can) for build up or debris
Other than that? May be low on freon. A service tech will cost $ BUT not having the unit service will cost more due to electrical consumption and excessive run times shortening the life of the system.

Only recently my portable heller air conditioner is oosing out buckets of water each night. does it mean it finished and needs replacement,


Portable air conditioners cool the air, and in so doing, dehumidify the air. The "buckets" of water are coming from the humid air in your environment, so you need to do things that will reduce humidity, of be prepared to empty the condensate receptacle fairly often.

Using a small room, closing doors and windows to the room you want cooled, avoiding cooking or heating water, reducing the frequency of people walking into/out of the room and limiting the number of people in the room will all help in reducing, and keeping low, the ambient humidity.

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed

Water is dripping on your ac from a duct? Or is the unit it self leaking Are you sure you don't need a Professional Air Duct Inspection?
