Rated 5 out of 5 by from This dealer has great products and services Trying to find a reputable company to replace my windows was not an easy task. Arizona Specialty exceeded my expectations. There kindly staff performed all tasks that they said they would do from the beginning of the project up to the end of the install. There was never any guess work as to when they were coming to do final measure, when product was set to come in and then the final install. The crew over did a fantastic job. Dealing with John and his staff at Arizona Specialty was such a wonderful experience. You can tell that customer satisfaction is there #1 goal. From start to finish they kept me in the loop and told me what to expect every step of the way. Overall the company met all my expectations. I will definitely be telling all my friends and family.

Rated 5 out of 5 by from Nice company and quality windows I had the Tuscany Milgard windows installed about a month ago the staff was very knowledgeable and cared about my concerns. When the installers came out to my home they were also very kind and worked hard the install came out great and everything was nice and clean when they left. It was a good experience all around I would definitely recommend this company.

Rated 5 out of 5 by from Great Dealer, Great Product! I am extremely happy with my new Milgard windows installation. Arizona Specialty did a professional job in protecting my floors and furniture throughout the whole installation process. The installation went smoothly and went exactly like they told us when I purchased them. After they were installed, I instantly noticed the difference in how quiet it was in my home and it seems like my AC is not running near as frequent. Also, I can no longer feel the wave of heat that i previously noticed came through with my old windows. These new windows definitely make a difference in keeping the heat out like I needed!
