Question about Ruud UBHC Air Conditioner

RUUD AC cycles warm & cold 24/7

Hello I have a ruud central ac which I bought in 2005. The compressor was chg'd 2 yrs ago under warrenty. Lately I notice that for quite a few hours during the day the air blows warm, then suddenly it will blow cold again. Repeat, repeat, repeat. It is a pattern or cycle of warm then cold. I originally thought it was blowing warm due to it being the hottest part of the day. But that's not right b/c it blows warm in the middle of the night too.I have it set at 77 but the temp inside can go as high as 84 during a warm 'cycle'.I have a digital thermostat that is 6 yrs old. Filter is chg'd every 30 dys. What do you think the problem is? I have someone coming to look at it in a few days & don't want to be taken for a ride.Thx----Mrs. Cornwall

Hello Anna Sounds like the compressor is overheating and stoping on overload internally.Then it cools down restarts and runs into overload again.I would like to see the freon pressures when running.Could have a clog/restriction in piping.I dont like that you went thru a compressor already, the original installition is suspect.The original (1st) failure cause must be corrected.Check the TXV valve replace, filter/dryer look for a kinked pipe are ideas for overheating.Make sure condenser coil is free (ari flow)& clean also.

I have a 2 ton central unit for my upstairs. It is 25 years old and still runing. Lately it will run all day when the outside heat is peaked and then when dark falls it will catch up at about 10:00pm and...

Hello, it could be that the unit is slightly undercharged and has a small leak. Usually when the cooling is needed the most the ac wont be able to keep up with the heat load as you mentioned.

We have a fairlynew 5 ton Central Ruud or Rudd unit that it is so noisy in the yard that we can not stay out there. We thinkit is the compressor. Help

I have a new 13 seer rheem or ruud same thing. I can not here it run. Uou must have a bad compressor. Ruud put schroll compressor in and when they start to go out they will drive you nuts they are so loud. Get it changed before your warranty runs out. Ruud will change your compressor if it to noisy. No problem. Russ
