I got estimates for a couple of options on a replacement ac system for the downstairs in my house. One is a two stage system with a zone system and one is a variable speed system. The two stage is a Lennox XC16 and the variable system is the Lennox XC20. While I feel like the variable system would be a more efficient option, I'm not sure it would justify the extra cost.
Is it worth the extra $3k for the variable speed system compared to the two stage system?
From the AC guy.
"Option B is a 5 ton two stage system with a variable speed furnace which we could put a zone system into and be able to control the common area separately from the master. The only catch with this option is that we would have to put a few registers from the common area on the master zone because there is too much airflow on a 5 ton system even in first stage for you master bedroom and bathroom space."
"Option C is a 5 ton XC20 variable speed complete system which would allow us to more precisely adjust airflow in your bedroom area."
