Bigger coils is most of it. Also would need a high efficiency blower motor inside if you want the "16 SEER" unit to really get it. Usually if you put a high SEER outdoor unit on a standard blower motor you get around 14 SEER.
Im not sure were to post so Im just going to ask:
Im looking at a comfortmaker 16 seer compressor... there is also a 13 seer compressor. Both are single phase. So what makes a 13 seer become a 16seer?
There is also a 16 seer single phase vs a 16seer dual phase. I understand that the compressor runs a two speeds ( I think) hence the dual phase. The dual phase is about 500 bucks more... but both are rated 16 seer...
I would think one is more efficient that the other, so why are they both rated 16 seer???

2-speed equipment only comes in 2, 3, 4 or 5 ton sizes. Don't make the mistake of installing too big of a unit.
Most A/C units installed are oversized to begin with.
