The 15-yr old A/C on my house is on its last legs... the R-22 leaks out every year and the compressor is on the fritz. So I'm in the market for a new A/C.
I live in northern Illinois, near chicago. My house is 15-yrs old, 2500 sq. feet, two stories, 4 bedroom, with big vaulted ceilings. Lots of windows, but they're decent units. My current A/C is 3.5 ton - some of the contractors recommend I replace it with a 3.5 ton, while others are quoting 4.0 ton units. (Others say 3.5 ton compressor with 4.0 ton evap)
How do I determine which size is correct?
Which of these units is more reliable? Are the prices fair?
Lennox 13ACX-48 13-seer 4-ton $
York LX YCJF 14.5 seer 4-ton $
Every company I research has people writing good and bad reviews, it's hard to make a choice I feel good about.
