View Full Version : Recommendation for a 3 ton AC??
Jun 29th, 2012, 08:13 PM
it's summer time, I don't think I can survive w/o AC....
2700 sized house, probably need a 3 ton AC unit.
Any recommendation on which model/brand to go with?? Feel free to throw in any good installers.

You will get lots of recomendations but I'd recomend:
Try to get as much seer as you can afford and make sure they don't use the existing lines since some installers like to pocket the money on the new copper and reuse the old stuff, which also saves them labour.
I personally went with Lennox 16.4 seer 2.5 ton of which there are several models but would not hesitate in getting the others I've suggested. My previous was Trane and it still worked after 25 years but I still changed it since it was 8 seer and just used to much electricity. I changed everything including the sub breaker panel.
Have a happy cool summer.

Get a real heat gain loss calc done. It will cost $100 or so but it is the only way to make sure you get the right size. There is a LOT more to it than sq ft. If you are around Kitchener I can give you a name.
Use this calculator from Lennox to get an idea of how much you will save by buying a higher SEER machine. http://www.lennox.com/resources/energycalculator.asp
You may be surprised how little difference it may make. For example, in Ontario going from 13 seer to 16 seer will save you $100 over 5 years or $20 per year. I expect the pay back period is a LONG time.
The higher SEER machines are built more for the southern US where cooling is much more intensive.

oh wow, thanks so much for the tips!
Just had a direct energy "consulting meeting" today. Totally an over priced sales pitch....didn't check my house at all.
Too bad I am in Markham.

The other thing is to get a number of quotes. I got 5 for my furnace+AC. They only take you an hour or so and I saved about $1000 by finding someone who was hungrier than the rest (but still qualified and recommended). The first 3 were similar but on the 4th I hit paydirt.
