How long should AC compressor last?
How long should the compressor last on a AC system?
My home almost never gets to the temperature that I set although (oddly) it doesn’t run constantly either. The problem presents especially on hot days—no surprise. The room temperature on the thermostat agrees with two other thermometers. If it matters, 3/2 courtyard villa. Sun-facing windows have blinds and lanai has awning. If I have to replace the compressor, what is a reasonable pirice? TIA. |

I suggest you call an HVAC contractor and have them check out the system.

Our unit lasted 19 years, Chuck Ferrell replaced Rheem with American Standard, $4600 after rebate.

If so, is it all the way to 'ON?' If not, give that a try...before calling anyone. Don't ask me how I know this. |

With humidistat functionality (humidity control), the system should still honor the temperature set point. What often happens is you will actually get below the temperature set point in an attempt to meet the humidity set point. Typical values are 2-3 degrees below the temperature set point, YMMV. He should still be calling a professional.

It's a very quick, easy thing to check and do...and could potentially solve his issue. Last edited by ColdNoMore; 05-05-2018 at 06:17 PM. Reason: Looked at humidistat control...had wrong %. |

I believe the OP stated that the system could not meet the temperature set point. With a properly functioning system, whether the humidity control is enabled (or not) should not impact whether the temperature set point is met. There could be any of a number of things wrong with his system. Instead of speculating and fiddling around he should, IMO, get a professional in to take a look. Depending on what system he has (and if it actually does have humidistat functionality) he may need to go into the service menu to check on the status and change it. I believe most homeowners should avoid going into the service menus. I go into my service menu occasionally but I RTFM. I would guess that he hasn't had the system looked at in some time. Periodic checkups are a good idea.

My guess is something is wrong. Maybe the unit is icing.
A safety switch could also be turning the system off and after the problem (maybe a backup of water) subsides lets the unit come back on. Probably best to have a company do an "annual" maintenance check. |

There is no "fiddling" required...to simply turn the dial to 'ON.' Last edited by ColdNoMore; 05-05-2018 at 06:28 PM. |

Yes, good ideas. That fact that he stated the system doesn't meet the temperature set point (on some days) yet doesn't run all the time would suggest a fault.

Sigh... You don't know what system the OP has and whether it requires going into a service menu (as does my 4 year old Carrier system), as I already stated. One more time, a properly functioning (and sized) system should still meet the temperature set point regardless of whether humidistat functionality is enabled (assuming it is even supported). The only advice the OP needs is stated in post #3.

The life expectancy of an a/c compressor depends on many factors from assembly line to the conditions it's unit is installed, average run time and continued care of unit. I've seen 2 condenser units with 2 continuous serial numbers and one had many problems while the other had no issues with both units having the same heat load conditions.
