3 ton Waterfurnance Evision unit $20,000
We just got a quote for 3 ton Waterfurnace Envision unit, 5 series $20,000. We live in SC. House is 1,550 sq ft. It is new construction. The system will be pond looped. Or $23,000 for the 7 series. Two questions. Is the quote comparable to what others have paid? And is there much of a difference between the 2 series? Also is there any disadvantage with having the system pond looped?
