This is pretty good, I`d only rearrange some of the sentences for priority of your point:
Q: "So, what is it you do?" (Meaning, what will I get if I use your company?)
A: "We help you save money on
your utility bills by making your house more energy-efficient. We run an inspection, then develop ways to
save you money while, at the same time, keeping the house comfortable."
As for the tagline:
Sage B Green --- Saving you money by reducing your utility bills.
:-) It`s not flashy or great, but I don`t think it needs to be. Everyone wants to save money...right?
