It may just be a contacts issue. Try this: Disconnect the power to the outside unit, both 220 and 110v. Open the service panel, and then open the metal enclosure around where the wiring enters the case. This is 220 volts to the contacts, controlled by a 110v relay. Inspect the contacts, and clean if necessary. For some reason, critters like to get into the contacet (ants and such), and they also foul over time. Make sure that there is no power on before you make any attempts to inspect or clean! If you have an electrical test meter, always verify that the circuit is dead! I clean my contacts with a fine sandpaper or emery board, and contact cleaner to further clean and lubricate the mechanical portion of it. Reassemble, and try it.

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

My outdoor AC unit is not coming on. Air is blowing out of my vents inside but the snowflake symbol on my thermostat is blinking and the air isn't cold. The fan on the unit isn't even running. Any...


check power to outside unit, check if it has a fused disconnect, if you have power and no blown fuses it could be a blown capicator that starts the fan and compressor...............

The fan is running and it is blowing air through the vents but its hot air. This happened overnight so I'm thinking it's not needing freon ???


The question would be, is your outside condensing unit working, fan and compressor? If not, you might have a capacitor out or a burnt motor/compressor. If everything on the outside unit is working properly, then you might have a refrigerant problem, and it can seem like it happens over-night sometimes. The charge just slowly decreases and eventually it will not condense or evaporate the way it needs to. Just some things to consider, hope it helps!

Sounds like compressor not running. may be a bad capacitor, could also be low on freon.

Heater air conditioner unit does not expel air


unless you have zones installed i.e. day and night you will probably find that the main duct off the unit has fallen off

Goodman PHJK048 Heat Pump Package


ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions hillbuck29@aol.com Hope this helps,Dave

check to make sure that the kids didn't change any other settings. Is the themostat still set for cold not hot? Also check the temp setting. Hope this helps.

Non-working outside unit


If your unit is blowing heat inside and it's not a heat pump. It will be most likely electric heat in your case.
Sounds like you have a split unit meaning the condenser is outside and the cooling and the heat features are inside or under your home.If your Rudd is a heat-pump the outside unit will cycle/blow cold air outside in winter and hot air will cycle/blow outside during the summer season. Now, if for some reason the heat  is not coming on inside the house, would be the only reason that you would need to be concerned. Being a heat relay or breaker of could cause that problem. Hope this helps you, Sea Breeze
