My Heatpump died this week. 11 Years old. And I'm getting a few quotes.
1)Some of the rooms in the upstairs (AH is in basement - 2 floors below) get little or no air from the registers. I have asked the contractors to let me know if I can upgrade from the current 3 ton and if it would make a difference. A couple of the contractors measured the ducts and recon I can go to 4 ton and that I would get more air movement.
House is 2600sq with another 1200sq for finished basement if it matters
Would it make a difference? Price seems to be about $ more.
Some of the contractors checked the returns and registers and no problem there (i.e. its not a problem with return air).
2)Next I'm seeing a 20%-30% premium for Carrier over Trane (in part I think the guys that install Carrier seems to be bigger operations and thus cost more). In short I realize the price differential is probably not just equipment cost. But I still would like to know if Carrier is worth the premium ITO life expectancy and cost of ownership over the life.
3)I'm getting some discrepancy on heatpack. Some quote 10kw, most 15kw and others quote 20kw. How do I figure out which it is? And should I run away from quotes that got it wrong?
4)SEER 13/14 vs 15: Costs savings over an assumed 10yr life would not pay for the price differential. Is it worth it?
5)Last question that I'm just not understanding from the contractors: 2 stage compressor vs 1 stage (current unit is 1 stage with variable fan on the AH). Again - is it worth it?
