Between Carrier, lennox ,Keeptrite , and Am Standard which product is the best.
My house is 4000 sq ft. and 17 year old.

Lennox Signature Series is good.
Then the higher the Efficiency, Higher the cost.

Mostly depends on what freon you are getting r-22 or 410, and then the warranty of the unit.

410 for A.C.
All are giving 10 yrs warranty.
So Catrrier or Lennox or keeprite for Furnace and A.C

If I had to pick from those 3 I would go with lennox

Thanks

Any one having any diff views.

Buy Carrier. Lennox can be a pain in the A$$ when it comes to getting replacement parts.
Make sure that all warranty are from the factory. Do not buy an additional warranty from a dealer unless it is a factory extended warranty. Many folks around here were made unhappy when the dealer they bought the warranty from went out of business and there warranty went out with the dealer. Factory backed warranty only.

My vote, no to Lennox, no to Keeprite,, in that order,, so take your choice from the other 2,, most very important is warranty and a well experanced installer with referances
