“I’m so glad we had Resource Central’s audit this year! Your sprinkler tech was very friendly and knowledgeable. He was happy to teach me about my system and how I could make slight tweaks to water my lawn more efficiently. Our lawn looks way better this year, and we’re not watering any more. What an awesome free service! Thank you!“

“The technician was excellent in knowledge and customer service. They found a broken sprinkler that was really adding to loss of water. Thanks for this program and the staff.”

“It is a great program, and every household should do it. It gave me a lot of useful information that I didn’t know about my lawn and how to water it!”
