Currently I have a 23 year old Duomatic Olsen Ultramax. I think this is 80% efficient. It's been through 3 blower motors and last year when the gas company came for the yearly maintenance the tech noted there was corrosion on the heat exchanger(but didn't detect any leaking CO)--they haven't come yet for this year's maintenance yet. If the heat exchanger is starting to go I'm thinking this year might be a good year to replace the furnace because of all the government grants, tax credits and store incentives.
So far I've gotten two ball park quotes one for a trane xv95 and the other a lennox gv61v. The two companies are coming next week to do load calculations and give me an actual quotes and model numbers. They're basically comparable and both include 10 years parts & labour. This is a 1950 sqft house in Ontario, Canada with all windows replaced with double pane low-e argon. I'll post again when I have some specifics but this is more of a general question I have right now:
In a lot of posts I see mention of a quality install being more important then brand. But I don't know how to judge one? Or how do I judge before there's even an install? Both sales people have been no-pressure; both mentioned a load calculation as part of the free estimate and both haven't trashed other brands(or even asked if I had gotten quotes elsewhere) If this is all I can go on to judge who will do it best how do you pick in the end when everything else is equal? The only people I know who have hvac work done have gone for the no-name companies that are pushing random "high efficiency" furnaces for very little money in those flyer packs that come in the mail so I don't have neighbour referrals.
