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.
