A 30-second minimum run-time for every compressor call


What exactly does this mean?

Generally means. That if you accidentally adjust the stat that the compressor starts. The compressor won't shut off right away if you turn the stat back down.

Some commercial units, have a built in 5 minute min compressor run time.

It was in a sale pitch. So a "compressor call" is a demand for cooling. . .

While I have y'alls attention, and 'cause there any many ways to do a bad install but only one way to do a
proper install,
what fraction of HOs are happy with new HVAC installs?
1/2?
1/4?

That would depend on the contractor you asked.

Judging by the number of complaints I see on the net.

75% are happy

Keep in mind, that most happy customers are not on the net talking about how happy they are. They're just enjoying it. Or busydoing other things, because the system is working good.

Yes. Self-selection clobbers randomness. Like you said, the people on the Net complaining over-represent the unhappy HOs so your 75% is a maximum.

There are many wrong ways to do statistics, HVAC installs, health care, you name it. . .

Having dealt with customers that didn't like, or think their system was running right.

I find that few are not happy, compared to the over all total systems installed.

Now, when you consider that more then 1,000,000 systems/units are installed in a year.

100,000 complaining people, compared to 900,000 not saying a word, makes it seem that more peopleare unhappy, then happy.
