Will it break a one room air conditioner to leave it on 64 degrees every night?

Question

Will it break a one room air conditioner to leave it on 64 degrees every night?

Answer 1

not at all.

Answer 2

"Break" it, no.  The compressor and fan motor are designed for continuous duty.  Running it at a lower temperature simply means the compressor runs longer.

However the more time the compressor runs, the shorter the life.  But, as a typical ac unit will last for 10 years or more, it's hardly worth considering

Answer 3

No it will not damage the unit provided the unit is operating correctly. However it will certainly run up you electric bill

Answer 4

It could cause damage if there are any air flow problems and your coils are freezing.  The fact that it runs constantly would never give it a chance to defrost.  If all conditions are perfect with your system then it probably should run OK.  Design conditions for most AC systems are to hold a 75° room temperature on a 95° day.
