★★★★★
"We spent 3 days getting quotes from various companies… The team at Dilmak were not pushy, explained the differences in units and how those units would perform in my home. They were extremely patient, informative and professional. The install went great and quick… They stayed in contact through the whole process including assisting with CPS rebates. Today, 2 months later, I can't be happier, it's 102 degrees outside and my unit is keeping us at temp… even the neighbors are jealous 🙃 Thanks Trevor, Mario, install team and office ladies, you're amazing!!!!!!"
