Central A/C Unit Help
I've just purchased and moved into a new home (3,106 sq. ft.) north of Toronto, Canada, that has:
- central air roughed-in (all ductwork is existing)
- south facing exposure with lots of windows (mainly south/north - not direct sunlight)
- very good insulation
- cellular binds on windows that also provide some insulation
Our summers here don't go much higher than 30+ degrees celsius at hottest points - and even when it does get that hot, it's usually for a day or so. Our warm weather can go from June to September, at best.
I recently went to a home show and was recommended some of the more recognized brands: Carrier, Lennox, Trane and York. I was told that I will need either a 3-ton or 3.5-ton unit. It was explained to me that the higher the SEER, the more efficient/less energy consumption the unit. Of course, as the SEERs increase, so does the price.
I am familiar with Lennox because the builder of my former home (half the size of new one) installed that brand. In 8 years, I had no problems/complaints with it but I also don't know any details about it like model/seer, etc.
The estimate I got for a Carrier unit was the lowest. Trane was the most expensive. One person I spoke to said York has the toughest construction (where coils are housed).
I'm hoping that someone(s) has some advice, recommendations for me. I'd greatly appreciate the help!
