See What Our Customers Are Saying
"We received several bids for the project. We chose AJ based on my friend's strong recommendation, as they had previously hired AJ to install a mini split. Although some bids offered to match or beat AJ's price, I agree with my friend that they are great people. They are very efficient, keep the site clean, maintain good communication, and are always on time. I highly recommend them!"
- Iris B.
