“Mark was friendly and professional. He answered my questions very well. He also was available for follow up questions and concerns.”

“Our company has worked with Diamon - Fusion International for several years. We have found their products to be superior among the "surface protection" products and we have used them all. Customer service is top notch! Very professional. We would highly recommend this company and their products!”

“We finally decided to replace our 25 year old windows and sliders. This was not an easy decision considering we have 33 windows and 3 sliding glass doors. We had 3 different companies come out and give us information and estimates. Although all estimates were comparable in price, Michael Lewis (sales) far surpassed the others with his knowledge and experience. He provided us details and recommendations that suited our needs perfectly. He has a wonderful attitude and made this process go very smoothly. Since Ameristar manufactures their own windows, and their factory is located in Riverside, I was invited to take a tour before deciding. I met with Maribel who gave me a tour. What a treat to see American made products being manufactured right in my own home town. I was sold! My beautiful new windows were completed and installed exactly as proposed. The installers were very professional and it was obvious they know windows and love what they do. Once again, Michael Lewis was outstanding in over seeing the project. He was on-site during the installation and clean up. He even jumped in and helped out. He definately provided us great customer service and went well above his expected job duty. If you are looking to replace windows, give Ameristar a call. You will be so glad you did!”

“We recently purchased a new home and contacted Air Tech to figure out how to install large sliding screens. The owner herself and her installer came out to show us how it could be done and explained exactly how ihey would look and work. That was followed up by a quote and an installation date. I would highly recommend using Air Tech if you want professional and timely service at a very fair price. Paula DeMars The Coach.”
