[QUOTE="CV355, post: 16188325, member: 181885"] Deja-vu, I had the same conversation when we had our HVAC system replaced in February. You're at the mercy of your existing vents/ductwork, unless you add more to have better control over flow. At the end of the day, it's dollars for comfort levels. Personally, I didn't feel like springing the extra money for crazy levels of control. The owner of the company said (paraphrasing) "Most modern 14/16 SEER systems are going to get you a little better efficiency than what you had when it was operating normally. Beyond that, you can pay out like crazy for higher levels of efficiency, but the return just isn't there. Where the money goes is towards comfort. I can sell you a system that keeps your house comfortable for $5500. Or I can sell you a system that controls each room individually within 2 degrees for $15k. It's up to you." Your Option B is already a step above what I had my entire system replaced with. It comes down to your personal preference, if you need that level of control. Just remember, more control = more hardware = more potential failure modes. A faulty zone control system cost me a LOT of money in 2014, so I said screw it and went as simple as possible. Was the option B to C cost delta of $3k including the cost of the added registers for the flow concerns? I find that our EcoBee with a single sensor helps regulate the temperature just fine by circulating air on regular intervals until the average of the two temp sensors (one in the t-stat, one remote sensor) hits the set point. Never really have a problem. [/QUOTE]
