Xcel Saver's Switch - hurt A/C longevity?

[Barry Robbins]

I have a saver's switch on the A/C unit on our primary residence. A friend of mine told me he had asked a friend of his who is a HVAC professional tell him those hurt the life of your A/C unit.

I did a search for "saver switch" and "saver's switch" on biggerpockets and throughout the internet and I have not seen this mentioned anywhere else.

I thought it would be a worthwhile topic to get some input on as it's not worth the $60 savings a year if it's going to burn out my compressor.

Does anyone have any thoughts or experiences with this?

Thanks!
