How much tech support and hardware coverage do I get with a refurbished MacBook Air if I don

Refurbished hardware sold by Apple comes with a 1 year warranty. Not that the ONLY place to purchase refurbished Apple equipment with a warranty is directly from Apple. Beware of so-called factory refurbished Apple hardware sold by 3rd parties. Those are NOT refurbished by Apple and do not have any Apple warranty coverage at all.

Everything about a refurb from Apple is just like new, except the box. It's plain brown cardboard. But the warranty for both hardware and software is the same as if you walked into Apple and bought a brand new device. It's really a great deal. I bought my 2011 MBA that way.

90 days of free phone support. 1 year hardware warranty. Just as if it were brand new.
