One way, is if they have to pull a permit asked the inspector what he or she thinks about what the job looks like?
At lest you will know the job will operate in a safe manner because they have followed the existing codes for your area.
Another way is hire another HVAC company and have them send out a NATE Service Technician to double check the job. You have spent all that good money to have the job done right so why not A good technician can look over a job and be able to tell you something within a hour or so.
That way if you get a good review from the second company you have a peace of mind of having the job done right..

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