Harbor Irrigation at 502 New York Avenue, Huntington, New York.

It is a pleasure to work with this company. After 15 years of the original installation, I thought I needed a lot of replacement heads. Turned out it was an adjustment and cleaning for all but two out of 26 heads. I wasn't misled into having more work done the necessary and was charged a fair price.
They also winterize properly so I haven't had a problem with frozen or burst lines or heads since I've started using them for the last five years.
