We had a AC unit that went out and needed to be replaced at our church. We were concerned because we wanted our congregants to be able to come to church and be comfortable as we all gathered to worship. Our unit went out in the peak of the summer heat and we knew it would be very uncomfortable if we didn’t get a new unit installed quickly. I called D&R and they came quickly to properly diagnose the issue, and then they moved quickly and efficiently to get us a new unit installed. We are now up and running and our congregants will be able to gather and worship comfortably. I highly recommend D&R for good, honest and fast work.
