They have done several jobs for me on home, business and rentals. Called one time because the A/C stopped working on my rental property on a very hot day.

Just this week, they handled a complex (at least for me!) problem with my heat pump. Jerry showed up when he said he would, and got right to work. The job took two visits to fix, but Jerry showed nothing but professionalism and focus to get my A/C and heat pump working properly. GNS sure picked a helluva guy when the signed Jerry up. Even better? THE PRICE WAS REASONABLE! Companies like GNS and people like Jerry are the reason why I go local when I need help with stuff going wrong at the house.
