Yesterday I had a sales rep from a reputable hvac contracting co visit my house.
My systems are old - 26 yrs.
We talked about replacment, since my utility bills are so high.
The number ( aka price, which I will not mention) that he showed me made me very depressed.
I just don't think that I can swallow a bowling ball that size at this time.
Part of what we discussed was a Zone Control System.
Today it occurred to me to ask you this:
Do you think that, instead of replacing everything and adding a Zone Control System, if I just added a Zone Control system to my existing systems, might that drop my hvac bills any significant amount?
