I love Halco, but I have friends who don't. I just ignore them and other friends the good stuff. But some people think Halco is a ripoff. They're just wrong.

Please note that I cannot recommend HALCO until after the project has been completed in September. The initial contact (energy audit, solar array plan, contract signing, etc.) has been excellent but we need to see how implementation goes.

James C. E. River Road

Planning (responsive and complete); Execution (rapid, creative and careful); Follow through (every detail attended to, no snafus). Perhaps most impressive was the quality of the personnel, from sales to final inspection, all outstanding. Your installation team (Aaran, Dalton, and Jeff) could not have been better.
