A smart watering system takes the guesswork out of your lawn care by adjusting based on local weather. Once installed, it runs on its own, saving you hours of manual labor and keeping your utility bills from spiking during the peak of the summer heat.
You should aim to have this installed by late spring. Booking contractors before the rush of the season usually gets you a better price. Get at least three quotes from local installers to make sure you are not overpaying for the hardware or the labor.
That 18-month window is a deadline, not free money. If you have a remaining balance after the window ends, you will start paying interest on whatever is left, which will quickly cost you more than you saved.
