Tips on chosing air conditioners and why thy are not cooling

Some one was asking why their airconditioner is not getting cold. here are soome tips.

1. low on coolant

2. tubular temperature unit is not functioning.

3. temperature of room is beyond the capacity of the unit. overworking
the unit beyond its capacity

4. a unit should be working to cool the room. It is not good for the size of the unit in btu's to be to large or too small. It is better to over work than under work an air conditioner.

Why isn't it heating?


Because its an air conditioner, not a heater?

Unit motor runs OK, but I have standing water. Water is not draining from sink.


The trap has a clog.
Put bucket under trap.
Get out some old towels.
Remove 2 nuts on trap, and it falls loose.
Clean the tubular pipes and then re-assemble.

05 dodge cummins,driving down roadway ,throttle will climb erratically for about 3-4 seconds when coming to a stop, it has electrical throttle connections ,no cables that i can see. When parked idling and hit throttle it over revs for 3-4 seconds also.


To retrieve OBDII Error codes from your Chrysler/Jeep/Dodge vehicle, do the following sequence with the key: ON-ACC-ON-ACC-ON and look at the odometer, that is where codes will be displayed. Here are the codes that you may/can get.

my 93 mercury topaz idles high doing warm days, and idles low doing cold days,what could that be.


1) weak anti freeze 2) defective thermostate 3) out of range coolant temperature sending unit

Any of these or combination of these will give you the sympthoms you are experiencing

Heating System


The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

See Figures 3 and 4
  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.
