Sanyo Mini-Split; New Outdoor Unit or New Condenser

Hi,

I live in Mihcigan and have a late 80s Sanyo Mini-Split system (18,000 BTU) in an addition over the garage (20x22). The condenser just failed. Quotes from one contractor for a new Mitsubishi unit came in really high, ~$XXXXXX.

To my surprise, I was able to locate a new outdoor unit (which has been discontinued), but I would have to find a contractor that would be willing to install it.

The contractor also called back to say they could replace the condenser for about 40% of the cost of a new unit.

My questions:

1) Are there any issues with simply putting in a new condenser on a unit this old?

2) Am I better off putting in the new outdoor unit? or are there issues with mixing a new consender unit with an old indoor unit?

I have other heating/cooling updates to do, so spending $XXXX on the addition is what I'm trying to avoid.

Thanks.

Talk to some more contractors, but edit out those prices, we can't talk price on this forum. We also can't discuss step by step DIY, but replacing the whole mini split with a new unit shouldn't be considered brain surgery. A bit of searching for a 18,000 btu mini split gave me a few options with 3 digits in the price.

And, What may I ask is that suposed to mean??
No ductwork issues, no thermostat wiring, nothing one person couldn't carry easily, flare nuts instead of soldering, what I mean is that it is much simpler and easier provided the person knows a bit about what to do.

It was maybe a caution as well against some installers that see mini splits as big threat to the investment they have in conventional AC equipment and training, and price installations to discourage sales vs central air.

Sorry about the pricing, but it's difficult to talk about repair versus replace without some sort of perspective....but I will follow the rules!

In any case, I guess my question boils down to whether repairing a 20 year old system is worth it? or more specifically, is putting new parts with 20 year old parts really a short term fix? Perhaps this is a question that can't be answered...maybe simply a risk/reward debate.

Right now, if I look to replace, I have one quote for a Mitsubishi mini-split system. Can anyone suggest which companies make the best mini-split for a competitive price?

Thanks.

Hitachi seems fairly top of the line, but I haven't really looked that much.

If the old condenser thing is repairable, 'maybe', but inside and out need to be matched, so I would replace the whole thing.

Seems like what you need to find is a local installer that does a lot of mini split work and understands the issues.

20 years old?
I wouldn't spend 10 cents on it.
Put it out of its misery. That system has done its job and doesn't owe you anything.
Watch what kind of advice you give folks dangler.
You've been on this site a little over a month and give out advice like you've been in the trade for decades.

Replacing my mini-split myself would be the last thing I would do.

I'm just trying to be financially smart and not spend more than I have to. And since most contractors seem to focus on one type mini-split manufacturer, I have to get several quotes to understand what my costs will be.
