JXA Homes provides excellent design and build service, here is a letter from an owner

John, 

I am writing this letter to appreciate your excellent job of building my energy 

efficient home. Last month was the hottest month I ever had in DC areas for 

the past 15 years. And the electricity bill is low, this is unbelievable. 

You must have done everything right to make the house energy efficient, from the 

setting of the house, window design, roof design, insulation, A/C planning to the 

build quality. Everything must be perfect to achieve this result.
