replacing system/deal?
 

Hi
I have a HVAC friend who removed a Heil Heat pump system modeph5542aka made in 2000 with a seer of 10.2&1/2 ton.
He quoted me 1600 for everything including install .Is this a good deal/brand .I dont want to spend a fortune but want something long lasting and have never owned a Heil .I dont want any major problems off it.They removed it when older couple built on to house so they needed a bigger system.
Just want to find out what i can before/if i buy it.
Any info is appreciated.
Thanks

12 year old used heat pump, and want long lasting shouldn't be used in the same sentence.

Could last 4 days, 4 months, or 14 years.
