HVAC Outside Unit Buzzing - Fan Running Intermittently

I was wondering about the service life myself.

A friend has a fairly new home with a high dollar lennox system. He's had nothing but trouble & is already thinking about replacing it.

Seems like nothing lasts like it used to.

you are going to do that, the capacitor is the most likely suspect part an d is also not very expensive.  So I would try that first.  The fan moto r will be a bit pricer so I'd hold off on that.  Most places will not tak e back electrical parts.- Hide quoted text -

OK, got that wrong then. I thought only the compressor had a cap. So, could be either the cap, the motor, or some intermittent wiring problem.

try oiling the fan motor if you can

Sadly practically none of them are oilable. While you can greatly extend t he life of a motor with periodic oiling less than 1% of the general populat ion is likely to do it on a regular basis.

Yep, I have three 1 1/2 ton r22 heat pumps. Two tranes and one goodman. Contrary to the ads the tranes have been more trouble than the goodman. And I have a nearly full can of r22. I'm hoping to keep them running as long as I can :-)

I didn't read this whole thread, but if you're hearing a buzzing noise, try tightening the screws on the outer panels of the unit.

Also, an iron core transformer is essentially an electromagnet that changes it's polarity 60 times per second, and the attraction to and repulsion from any nearby metal panels can cause both the transformer and panel to vibrate. So, tighten any mounting screws or bolts on transformers, too.

Buzzed driving is Drunk driving !!!!

Yeah, the fan hums intermittently. But, can you sing the secone verse of intermittentlly?
