My heater or AC when it's turned on during the summer hours, makes a very strange noise but works just fine. It's pretty loud and goes constantly from a low to high noise about every 2 seconds. Kinda like revving an engine, then taking your foot off the pedal. I know that's a horrible way to describe it, but it's loud.. too loud. Even though it works, I still would rather replace the part if it will mean the sound will go away. I was thinking this may be normal, but the sound seems to be coming from the large cylinder to the right of the unit that's standing straight up. Any ideas?

I know that I described the sound strangely but does it sound kinda like that? Surely this isn't normal. Could just be wear and tear over time and being a 13 year old unit. Assumptions, of course.

Why don't you take a video (or audio recording) of the noise and post it... people will be able to tell better.

I will take care of this tonight, and post it. Not sure how I'm going to set up an audio file on here... Maybe I can do a video with my iPhone.

Might be a bearing going out on the fan motor.

Wow! That is loud. Ck. the compressor mounting bushings. Does it change when you put your hand on it and try to move it around?

No.. I tried that. You're talking about the white cylinder piece right? I showed it about half way through the video. I lit it up with my spotlight. I put my hand on it, still rattled.

To be honest, you really think mounting bushings would cause the fluctuation in sound? Lets pretend that it needs to be replaced because its getting ready to go. Where can I get one?

Very possible. Ours has been like that since we bought the boat in 2011. Heat and AC make same noise.
Works like a charm -- just sounds god awful....

Yes, I agree. It works.. well. I'd rather spend the money and replace the unit if that awful sound goes away. I can't even watch TV with it turned ALL the way up!

If its worth $1200 or so for the new unit to you 
go for it. I'm waiting for death... Especially since my unit is under the stairs in the '98.
Although, our water outlet is showing rust, so I'd suspect I'll be replacing next season...

Just the compressor = $1,200? Good grief.. Surely it isn't that much. I can understand the whole unit being that much.If its worth $1200 or so for the new unit to you

With that unit, you generally do not just replace the compressor. It's not a financially smart move (what I've been told).
I'm sure others on here have more experience. Watching this unfold though as I'm in the same spot.

Just looked it up with help from the general discussion board, to replace = $2,600 online.
