Help! I'm trying to make the difficult choice between HP's with advice from "sales guys". These thing's ain't cheap so I figure it is worth careful thought. No offence to the sales guys out there - but let's just say they all say different things and it is hard to make sense of it.
So here goes, I am looking a 3 models from Lennox: HPX12, HPX15 and HPX16 - there is a pretty big span in pricing, the 16 is nearly 50% more than the 12 - and I'm not sure it is worth it. I would really appreciate any advice from the pros. Here are the facts:
1) I am located in Montreal, Canada, 2000sqft house.
2) recommended unit size is 3tons
3) I have a new G61V lennox furnace
4) Elec rates here in Quebec are cheap, for comparison, we pay about 1/3rd the rate of someone in Calif, and in addition, HQ gives consumer a 40% discount on power when the temp is above -12C (ie, 75%+ of the year)
HPX12 vs 15: Really, the only real benefit I see between the 12 and 15 is efficiency. Now, I figure we pay low elec rates so at best the cost difference is going to be $50-100 in operating/year. The cost diff between these two units (installed is $600). The 15 is a little quieter as well, but just 1dB. So I don't really see a strong argument for going for the 15 over the 12.
What the sales guy says: One sales guy told me the HPX12 is a discontinued (or soon to be) model and is 2X more expensive to service. Even if this is true, why does that matter, it is warranteed by Lennox and even if I bought the HPX15 and it 7yrs it breaks, it will probably not be a current model at the time anyway. So why does this matter.
As for the noise issue, one sales guy said the 12 has nearly the same dB as the 15 - but the 12 was higher pitched and "sounded" noiser. (ok, this sounds like complete crap to me, but I figure, why not ask the pros).
HPX15 vs HPX16: Ok, the 16 is a lot more efficient than the 15 or 12. And it is 2 stage - which is good. Maybe that would save me $200/yr at best. However, this unit is a lot more expensive, nearly $2000 more than the HPX12. So the cost difference would take 10yrs to pay back or more. Other than efficiency, I really don't see a lot of advantage to going with a 2 stage unit.
What the sales guy says: I have a 2 stage furnace so I should go with a 2 stage HP? He really could not justify why, but that was his argument.
Based on the above I figure just go with the HPX12, it is good equipment from a reputable supplier, the efficiency differences of the more costly units would take many years to pay back (I figure if pay back is more than 5 years it is not worth it).
What would you do?
