Okay, so reading the (hundreds of) posts below, I get the impression that when
replacing my central A/C, it's important to
make sure the installer is competent and does the job correctly.
Only one little problem... *how* do I make sure the installer is competent and
does the job correctly?
Any particular questions to ask, certifications to check for, etc?
Should I be looking for them to do a complete manual J / manual D / ?? assesment
when replacing existing equipment? The
replacement is due to a compressor failure so I'm probably looking at an outside
unit plus evaporator coil (should the lines
be replaced also?), but to reuse the existing furnace.
Speaking as a semi-ignorant homeowner, it doesn't seem to me the old unit was
grossly under- or oversized - it cooled quite
well but not excessively and did a good job of controlling humidity.

Consider the following:
a.) Ask neighbors and/or anyone knowledgable for names of good hvac
contractors.
b.) Go to BBB, pick, say, 6 contractors in your area with best records.
After this, I worked up specs for the job (given full details, folks
here will help), started calling contractors asking for name of
someone who could render informal estimate, then faxed the specs
to them. They call back with a number.
Then called the 2 or 3 best estimates to do on-site evaluations.
If it's really a simple job and old ac worked fine, old specs
= new specs (i.e. tonnage, btu's).
Beeeeeeeeeeeeeee careful (evaluating the job).

Ask everyone you know if they've used (and been happy with) a particular
HVAC contractor, and for how long they've used them.

You can only do that by personally understanding the technology yourself.
If you're ignorant of the technology, then you're depending on hiring
derivative opinions of others for advice, but properly selecting an advisor
is also impossible with that ignorance. They all claim competence and
quality and sound believable, or they wouldn't be in business. It matters
not what they say or how they sound, only how they perform. And
performance is only known to you by direct examination.
The only exception to this is if someone you love is an expert, and you can
trust them to be critical in your place.
