Ron really knows his products and took his time explaining & demonstrating his windows. Ron was sensitive to my budget and gave me probably the best window on the market at an affordable price. His workers were punctual, professional, & extremely neat. They finished the job in one day. The heating bill went down 40% (winter months) after the windows were installed. The air conditioning doesn't need to run that much in the summer months. This is the only window company I would recommend.
