Question about Air Conditioners

1 Answer

Central air is not cooling this evening. We shut the system off for a couple of hours to make sure if it was not frozen up. I have taken the cover off the thermostat ..there are two vials inside---should I be looking for the bubbles on the top and bottom to be level? Unit is 10 years old.

    Will take a look at this when I get home this evening. Wow! That would be great! Someone at work told me the "compressor might be grounded" any idea what the heck that means and is that a problem or just a fact. Thanks..

Neither. Your problem is simple. If you look inside your unit which is located outside. The compressor. There should be a silver, oval in shape, part usually affixed to the wall of the unit. This device, if swollen or mishapen, thats your culprit. Replacement cost is approximately $15.00. The only other problem you may have without looking at the unit is. It may have a serious leak that have allowed all freon to escape. If there are no freon your unit will not freeze up.

    Inside the unit the compressor is located. A large black cylinder. On the side of the compressor is a black box with wires going inside of it. Usually there are three wires. If one of these connections works loose (which is rare) your unit will react similiar to your original problems described. The important word is similiar. "Compressor is grounded" ???? That terminology has not been used in my field of interest as something derogatory. Beats me what they are trying to convey.

Works fine on cooling mode but on heating mode will sometimes make a noise like air brakes and then switch off.


Not sure what type of unit your speaking of, On a central Ah from what your describing, sounds like the outside txv is causing your issue and the high or low pressure switches are shutting down the system on safety.

My central air conditioner wont blow out cool air and wont blow enough to cool the house what could be the problem?


Check the Filter 1st, that might lead you to find either a frozen coil.If neither of those things
are the problem, check to make sure the blower is operating.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

We have bought a home with the wite rodgers thermostat 1f85-275 it doesn't seem to be working. on the top right of the screen it states 1&2 stages? anyway, help would be appriciated


Hi, this thermostat is for central heat and air systems that have more then 1 stage of heating or cooling. For example, your unit may have 2 stages of cooling, as in 2 compressors, or 1 stage of cooling and 2 stages of heating as used in commercial heat pumps. This is a multi-stage heat pump thermostat. It may be just a matter of programming the stat. If you can find a manual on it, this would help. If you open the cover, it should have directions on how to program it.Make sure you have power to everything, check all breakers to see if they may be shut of, even if you have a display, doesn't mean you have high voltage to run the unit. Make sure fan is in auto, and on heat or cool, and temperature set for it to come on. Please keep me posted.

Central air/heat pump not putting out cold air


I have some things for you to check. If you look at the outside unit the lines going into the house. Are they frozen? Have you had any yard work done, the reason I ask is they could have accidentally cut or pulled out the thermostat wires to the ac unit. Also, inside check for the same thing, frozen lines. Also, you may want to check the drain coming from the inside unit, it may be clogged.

Neither Roof Air Works


Yes and no .. Freezing temps should not affect your A/C at all ... BUT .. there is a freeze control box, its called a control unit to prevent itself from freezing up and burning out, take down the lower cover and you will see it. Your problem is more likely to be more central since neither are working Thermostat or even the control box's in genera, even could be a freon problem if the cold weather was really bad and you could have a leak on your lines, check it out and see what you got!

Large office air conditioner


Shut off the cooling and leave the fan in the on position. If the A/C cooling coil is frozen over it will stop air circulation. After you shut the cooling off look down through the fan on the roof top unit and look for any sign of ice on the big line going to the compressor. This would be a sign of the frozen A/C coil. After about an hour or so you should start to feel air movement.

To prevent the coil from freezing up operate the fan in the on position while the air conditioning system is in the A/C mode. Not automatic.

Not cooling


every single component in your cooling unit is needed for it to work, so anything can shut it down. If you could provide more information as to what type of unit you have: is it a central heat and air package unit? or central split system (furnace indoors and condenser outside)? or a wall a/c? Does any part of the system/unit do anything?
