AJ was extremely professional, friendly, and a pleasure to work with. He took his time to go over examples and costs of other windows and other companies warranties. The windows that AHT offer are much more efficient and a higher quality overall, including a 50 YEAR WARRANTY! Great company to work with. I highly recommend for windows and doors.

We worked with Craig who was amazing and friendly. He had so much knowledge on windows that helped us make the decision to make the switch to a new sliding door that was secure and energy efficient. If you're looking for new windows and sliding doors that will last a life time, i would highly recommend this company. Services: General door installation, Custom doors

We made a mistake signing up for their drawing at the Home show in Green Bay For free window. They called to verify information and tried to set up an appointment. We Advised them we were not interested at this point as we are not ready to start this project. They called again and on 3 calls we told them you already called us and we told you we are not interested.
They Continued to call us every day for a few weeks leaving messages To call them back, Until we finally had to block their number. They would not leave us alone. If they are this pushy now there's no way we'd have them come to out home to quote or even consider hiring them. Not impressed at all. They ruined their chance of us using their company for our window replacements.

My experience with AHT was nearly identical to 2 other reviewers here. I tried to schedule a consultation with this company twice to replace the windows in our home. Initially, they asked questions that felt personal, uncomfortable, and unnecessary for a window replacement quote: how long I've owned my home, what my work hours were, if there was anyone else on the deed, my husband's first, last, and middle name, his work hours.
As I got more uncomfortable, I politely refused to answer any more questions over the phone. Then it came time to schedule a visit. They pressed me to schedule something where both my husband and I can be present. I told them that was going to be difficult because of our conflicting work schedules but also we'd prefer not to have our young, unmasked kids here when people outside our household are going to be in the house.
It is the pandemic, after all. They then said they'll call back when my husband and I have looked at our schedules and can find a common time for them to come out. They called again several times over the next week. Finally, I picked up. Again, we tried to schedule something, and again they refused to schedule me without my husband. I told them my husband and I trust each other to make decisions and keep each other informed.
They said that it's about more than just quoting a price. At the consultation they'll discuss color and styles too. So what? That is also something my husband will trust me to make a decision about. I told them it's strange that they're turning away business. Here I am, trying to get them to come out to give a quote. They just reiterated their policy of needing both people present at the consultation.
So I said I guess I'll call someone else. My guess is they want both people present at the consultation so they can get the contract signed then and there without the excuse of "I'll need to talk to my partner."

Anissa Trefren was very informative and knowledgeable explaining from replacing, installing windows in our home. She made the process very easy and hassle free. She sold us on purchasing AHT windows when she demonstrated the heat shield and how well the new windows will keep the outside elements from entering in the the house. She did a great job in demonstrating the quality of the products used in the manufacturing of the windows.
