Remove the front cover of the unit to expose the cooling coil. Put the unit on and observe if there will be formation of frost (ice) on the coil. If there's frost formation, the common cause is dirty cooling coil. Have it cleaned using an alkali base coil cleaner. If the coil is clean, then the problem is the fan motor. It might be turning slow due to copper loss. Have it replaced.

SOURCE: Our air conditioner seems to be working fine yet t

check outside unit large pipe should be cool or even very cold small pipe should be warm to touch that will eliminate some questions in order to solve problem also check circuit breaker for outdoor unit see if fan on outdooor unit is running and listen for compressor hum

SOURCE: doesnt cool room as in prev years

yes the side vents need to be outside the window and if they aren't - the unit will not cool correctly.

Hope this helps.

SOURCE: My outside a/c condensing unit's fan runs, but

Start the unit and go outside to see if the insulated pipe is sweating or cold, hot air should be discharging from top of outside unit. Since the breaker is not tripping, my best guess is the compressor is not operating. You might have to replace the capacitor.

If you can hear the compressor operating, then most
likely needs refrigerant

Testimonial: "Thanks for providing some additional clues and methods to pin down what needs replaced. Now I need to determine whether the run capacitor or the other part, for which I can't find the name, is at fault, unless the compressor is bad."

Should air cooling unit vent be in or out


If this is a forced air system and you are talking about the wall vent. It is very ossible you will need to
make sure your blower motor on the indoor unit is
on high speed. Sometimes in the duct work they put
a manual damper, follow ductwork back from room until you find one or not and make sure it is open.

Reverse cycle air conditioning unit theremostat is only a couple of feet away from return air vent. The room where the vent and thermostat are located is in the middle of a building and has no windows....


ok i will try if there is only one return then you need one move the stat= thermostat to a area where temp is about same as the outside rooms. and have a retrun in each room near to the back of the room away from windows. if can not move the stat then move the returns. do have cool air on the windows if not you need to move them the air duct! or are there any supply in the middel room? if there are then ether remove them or greatly reduse the amount of air to that room do it at the unite if you can, a Dapper.Basic idea here is you find your Heat or cool load which is the windows.
so need your air on them. if you leave your return where it is are the door touching carpet it should have about 1" to 1"1/2 off the bottom so air can to the retrun. Hope this helps Paul

Ac unit cools entire home except for one bedroom


The issue may not be confined to airflow alone. An air conditioner makes us more comfortable through two basic rules of physics.
It removes sensible heat (the temperature you feel) and removes moisture from the air. Dry air enhances the bodies own cooling system allowing perspiration to evaporate more quickly which speeds the removal of heat from the body, this is why 85 and dry feels more comfortable than 72 moist degrees.

to ensure the ducts are balanced properly one must use an anemometer which is a tool used to calculate airflow by the pro's. Being that most homeowners do not have access to one there are some good observations to make using a pocket thermometer and your own senses:
  1. Ensure the guest room vent is the same size as the master bedroom.
  2. Ensure the supply duct for the suspect vent is the same diameter and approximate distance from the main plenum (where the ducts originate) as the master bedroom.
  3. Is the air emminating from the suspect vent approximately the same in volume as the master bedroom (does it feel and sound the same).
  4. The issue exists even if the guest bedroom door is left open.
  5. The air temperature measured at the vents is within 3-5 degrees of each other.
If 1 - 4 are true check for #5, if # 5 is false make sure the suspect ducting is insulated or covered well by attic insulation.

If 1, 2, 3 or 4 are false: Ensure the following:
  • The guest room ducting does not have a damper hidden under insulation or duct wrap.
  • The duct has not been crushed or restricted.
NOTE: internaly insulated ducts can be restricted on the inside by fallen insulation while appearing normal on the outside.

If #5 is false (issue goes away if the door is left open) the door may need to be cut off a bit more at the bottom or a grill installed to allow the air coming into the room a place to go.

If none of the above reveal the culprit concider the room itelf, it may have a higher heat load than the others.
A higher heat load may be due to dislodged, compacted and or wet insulation in the walls or attic, feel the walls and ceilings with your hands, how does it compare with cooler rooms?
If the walls and ceiling feel about the same and the tests above did not expose an issue its time to call the contractor back in, make sure the static pressure is checked in each duct a foot or so downstream of the the plenum and again just upstream of the vent. A duct with air pressure higher or lower when compared with the others could mean a variety of issues with the duct or where it connects to the plenum.

I am living in a home with a carrier furnace. The furnace is in the back part of the house in a store room. It has two- 2 1/2 inch plastic pipes. One that suppplies air to the furnace and the other is...


As long as the fresh air intake pipe to the furnace is not plugged up the second vent is not needed some homes when they are new are air tight and need a fresh air circulation system
