DANBY air conditioners JUNK?

Hi!

that

That is a good idea...but I differ with you on how long the unit needs to operate. Maybe some of them can come up to cooling nearly instantly, but the various units I've worked with over the years have required a few minutes to "get up to full speed" after having sat idle for a while.

I don't know that age has to do with this effect...I've got a 30+ year old Coldspot dehumidifier and some nearly-new Frigidaire window A/C units, with plenty of things in between and all take a while to come up after having been stored.

Ironically if the condenser is _very_ cool you get no pressure and hence no cooling. Once the condenser is hot the pressure builds up and you get the pressure differential required to provide cooling.

Really? Do you know why this is?

I doubt such a broad statement can be made.

A BTU is a BTU. Since the coils in a high efficiency unit are more extensive, it may take a bit longer to get going but this really shouldn't affect the validity of a quick test.

No they don't, the cooling time depends on the BTU capacity of the unit. Higher efficiency A/C units will generally be physically larger for a given BTU capacity so a higher efficiency unit of the same physical size as a lower efficiency unit will take longer to cool but if you go just by the BTU (or tonnage in which case 1 ton = 12,000 BTU) two units of the same spec will cool similarly.

stuff

Either the compressor isn't running or the system has lost it's charge. Make sure you've got it set properly and if that's the case then return it for a new one.

never

There was probably a pinhole leak in one of the soldered plumbing connections, it may have opened up during normal shipping. There's not much difference between brands of A/C units.
