The Welzig team evaluated and provided solutions for cooling issues in our home. We were able to quickly get an appointment for an initial evaluation, and the technician, Bob, arrived timely and listened to our concerns and offered options. We had a follow-up appointment with Casey Welzig to discuss installing a new system. He was very thorough in his explanations and transparent about potential limitations. We opted for a new system, which the team was able to install 2 days after we decided to purchase. James, Anthony, and the team did a great job on the installation. They went above and beyond and stayed late to finish so that we would not be without cooling overnight. Our new system has been performing well - able to keep the house cool in 90+ degree weather that our prior system could not handle. All-in-all, a great experience with the Welzig team.
