D&H took care of us quickly and professionally. AC system not working over the weekend. I reached out to D&H for … More a service call and they send Austin out early the next day. He made his assessment, discussed all options, and allowed me time to review my options with no pressure. Ultimately, we decided on replacing the unit. That very same day, Curtis arrived to discuss various replacement options. He was an amazing assistance to us and thoroughly went over the finance options. The next day Darrell arrived and took measurements for our new system. He also thoroughly described the system components and how they will be installed. Finally, Marty and his professional crew arrived for the installation and completed the job in less than 4 hours. He took me step by step on what was being installed and provided instructions for the new thermostat. I went from having no AC on Sunday to a complete installation by noon Wednesday that same week. This company is truly amazing!
