Central Air Conditioning

Check on there warranty via the website or another means. I am under the understading that the warranty is 5 years on the cabinet items and 10 on the compresser. The coil is part of the sealed system and my guess is it ts fine, get another written service order as somthing is wrong here. My guess is a bad fitting or a leak in the line and you are getting raped for another coil. Call the local area Carrier rep (numbers may be on web site) this is not right.

Ripsnort , if you have already purchased your Carrier central air, my advice to you is request a serviceman come out to your place and do a leak inspection on the coils, while the unit is still under warranty.  I think my coils had a very slow leak from the day of installation.

I stood there as they did this during installation.  I will do so again before the warrranty expires, thks for that info.

The installer told me to never set the thermostat for lower than 70 deg because this *will* cause the coils to freeze up.  We keep the thermostat at 74 deg. with the airconditioner on. This keeps the house comfortable when the temp exceeds 80 deg. and the upstairs gets about 76 deg. since we had the hot air purge fan moved from the floor of the upstairs hallway to the ceiling.

Rip an AC unit that has the proper air flow (no cloged filters ect.) should not ice up. Ice is caused from low airflow or low Freon. If the evaporatior coil (inside unit, air hander) gets too cold ice can form and this will slow the air flow down even more, then  more ice will form. The air entering the unit must get very cold for this to happen in a normaly operating unit. If the freon is low then the  heat is not removed to the condenser unit properly and this can ice up the coils. Think of a can of compressed air it gets hot when you pump up the can (compresser pumps up the freon) then return to room temp while under pressure (freon is cooled out side in the condenser) then it gets cold when you release the pressure (freon is returned to the house as a high pressure gas and then pressure is released and gas absorbes heat and returns to liquid taking heat with it back to the outside) Think of it as a heat pump moving the heat to the outside. Ice should not form unless the temp is low (40's) and you need a great deal of humidity (hard to get with such cold air) for this to happen. Your unit should NOT freeze up at 70's if everything is working properly.  

The freon is a hot high pressure gas from the compressure then it goes to the condenser coils and the heat is removed (still a high pressure gas) then it is sent to the evaporator coils where it's pressure is released and it gets cold and turned back into a liquid as it absorbes the heat and returns to the comp.

rinse and repeat

I am amazed at the myths and voodoo surrounding AC units, it is a very simple process really.

Carrier and Trane are both fine

Regards,

I didn't say it would freeze up at 70, what I said was below 70, and I might add he said on extremely hot days, keep it at 70 or above. You tell me (shrugs) me know nothing about A/C, and this guy that installed it has done it for 27 years (shrugs)

Sorry I thought he said It *will* freeze up by your statement.

It would need to get in the 40's for it to do so. I only responded as some folks turn the units down for a party and this should be no problem. I have set my unit at 65 with a house full (unit runs nonstop) with nary a problem, course the temp never gets below 74 or so with all the people and the doors opening all the time.
