HVAC Install for primary residence/partial rental

[John Fakish]

Hello!

I need a 3 ton system for a split level home. The basement is rented out and in approximately 5 years, I will be moving out of the upstairs unit and renting out both the upstairs and the downstairs. I live in Salt Lake City. My current system is very old

I've been quoted $10,000 for a Carrier 80% 2-stage furnace and the Carrier 13 Seer AC unit. This comes with an Aerus Air Scrubber and an Ecobee smart thermostat and sensor to ensure I can keep the basement and upstairs temps nearer to each other and at least some cooking smells don't permeate. I have also been quoted about $8,000 for an Amana system with air scrubber and smart thermostat.

What are your thoughts? Is the Carrier worth it? I would say that longevity is important and temperature homogeneity. I feel that getting a High Efficiency unit is not worth the investment if I am moving out within 5 years - and I'll see a some efficiency from even just a low upgrade based on my current outdated system. I can't find enough info on Carrier vs builder grade.

Appreciate all the insights!
