Whitney M. Warrior-Deerinwater
Had a great experience, especially the consultation! The information was as they presented, no hidden extras, it was a successful home project and the boys were so great to talk to and ask questions. All were knowledgeable and all worked efficiently. They also seemed to enjoy their work and how they happily carried one with each other. They needed to take more of the snacks but they were such a great representative of Girdners to have on our home projects! Highly recommended. Owner is also great to work with. Looking forward to working with the company again!!

Wyatt and Braxton were amazing. Very timely, cleaned up behind themselves all the way. Incredibly polite and professional. They even remembered my dog from the last time they were here. Re-upped for the subscription. Well worth of the cost. Tons of value

They gave us an excellent deal and were really helpful when replacing our whole heating and air system! A big thanks to Joe, Wyatt and Garrett; they did an amazing job and worked an extra long day trying to get our AC working for us!
Definitely a great job and highly recommend them!
Deborah White
We had our HVAC system replaced in August 2024, and the experience was excellent from start to finish. The team completed the installation in a very timely manner and has been a pleasure to work with ever since. The system has worked perfectly, and anytime we’ve had a question, they’ve responded quickly and professionally. We are very, very happy with both the product and the service—highly recommend!
