"I got sprinkler system installed in summer of 2020 and the initial team did a fantastic job. They were professional and knowlegeable. I often called once or twice per year to get tuned up. The guy they usually send, Steve, was always very unprofessional and always in a rush..but he's just there for tune up so what? In november -december of 2022 I called Automatic irrigation design frequently, keeping them up to date on a project I would be starting, which would involve moving a few of the sprinklers further back to do an extension. Steve came out several times and always made excuse about not being able to do something, or why the job cant be done. Finally he came out on 1/30/23 to move and re-run the water lines to the sprinkler main box. My contractor didn't want to have anything to do with touching the sprinkler system nor plumbing to prevent the issue i am having now. I updated Automatic Irrigation System on everything, asked their opinions and agreed with them on when to do what. I paid $754.94 to have this new main run. When my project was finished in March, we called them back to reconnect and turn on system to prepare for spring. Again they sent Steve, and as usual, within 5 minutes of being there he started shouting that its a bigger job than he thinks, and that he cant do it alone, because the sprinkler valves were damaged and blocked by the contractor. He tried to explain that when the contactors were doing their plumbing they might have gotted sauder dust in the system blocking the valves. Only probem is, Steve was the one who ran the pipes from the old building to the valve box. He and my contractor had a back and forth about who did what, while I have to finally come up with the funds to get my system fixed. This happened in March, and today May 16th, they have not been back to repair my system, even though I agreed to pay the $950, plus what ever issue come up after they are done with the job. Debra , the office clerk at first seems ok. Later I found her to be rude and unprofessional. First, they gave me a 6-weeks date for service, after the damage was announced. Each time I called..she would pull Steve into our conversations ( and for some reason, Steve is always in the office as busy as they say they are...9am, 11am, 2pm, 4pm, he is always there). My final call today was to request an earlier service date as my newly laid grass was drying out and dying from lack of water. Why do I have to suffer anymore, when we have been going at this since december/november. Debra became upset when I mentioned, that even though it could be Steve that cause the damage, that im willing to pay for, they were not even showing common courtesy by trying to work with the customer. Instead, she put Steve on the line, and after several minutes of me and him going back and forth ( where he stated, "how can you blame me? I blame you for digging up your yard before calling us." (That was a total lie as I mentioned before, that i kept calling them every step of the way, asking them what they needed to do, and working with them. They did nothing to show loyalty, they were not apologetic, and they did absolutely nothing to de-escalate the situation. Debra tried to get me to stop talking, after having difficulty getting Steve to stop shouting at me. I could not believe I was a loyal cutomer to a company that was rude, disloyal, defensive and watented to take no responsibility for their part in destroying my 2 year old sprinkler system that was working quite fine before Stee made the cahnges and did his saudering, without blowing out the pipes. Still, I have no prove who did what. But my plumber /contractor was willing to go half with me to get the system up and running. Even though I was not asking , AID offered nothing. All they did was gave me a date of May 28th..6 weeks from problem...and had Steve in the office cursed me out on 2 separaste ocaasions. The one star i gave this company is for the work the guys did initally in 2020. Overall service, especially customer service, 0 stars."

FAQs for lawn irrigation projects in Smithtown, NY
While watering your lawn by hand might save you money upfront, installing and using a lawn irrigation system does save you money over time. You are less likely to overwater your lawn with a professional irrigation system, which will cause a reduction in water usage. These systems use the right amount of water without waste. In addition, watering your lawn the correct amount will also help prevent different fungi from growing, saving you money in fungi removal costs.
Lawn irrigation is the process of getting water to your lawn, grass and all, for it to grow. There are five main types of lawn irrigation methods:
Manual irrigation puts you in charge of the flow of water. Using a sprinkler head on your hose is best to evenly distribute the water across your entire lawn. This doesn’t take much time but requires you to be physically outside holding the hose.
Above-ground sprinklers attach to your hose and rotate or oscillate around your lawn. Since these are above-ground, they’ll need to be moved when it’s time to mow, and depending on the size of your property, you might need to move it around your yard for full coverage.
In-ground sprinklers are flush with the ground when not in use but pop up above the ground level when it's time to water the lawn. Piping for these sprinklers is all found underground, and there are different types of sprinkler heads for different uses and lawn sizes.
Drip irrigation involves drip lines that are more efficient than sprinklers for more extensive lawns. This involves a lot of digging since they are installed underground, but it makes it easy for you to mow.
Rainwater collection and irrigation uses nature’s precipitation to water your lawn. This option might not be available in every area since semi-reliable rainfall is needed, though the barrels for this system can range from 15 gallons to 10,000 gallons or more.
Even though having a lawn irrigation system to water your lawn is efficient, you do not want to run it daily. It’s best to run your system two to three times a week. The length of time to run your system varies on factors like wind, temperature, and the variety of your grass, but 10 to 20 minutes each time is generally preferred. If you water too frequently, you’ll drown your grass and plants.
The cost of a lawn sprinkler system is $2,550 for the average homeowner. However, this price can range from $350 to $5,000 or more, depending on the type of sprinkler system you install, the size of your yard, and the type of sprinkler heads you choose. For example, rotating or oscillating sprinkler heads are more expensive than stationary ones, making the cost for one sprinkler head $2.50 to $30 each. Likewise, a yard that is 1/4 of an acre in size averages a total average price of $2,460; however, a one-acre yard averages a cost of $9,840.
The total time it takes to install a lawn irrigation system is roughly one to two days. This includes digging trenches for any necessary underground piping, placing the piping, wiring, sprinkler heads, and valves, and connecting your sprinkler system to your water supply. If you have a lawn larger than one acre, or if there are any municipality regulations that extend the project, you can expect the timeline to be closer to two days.
