Lesley Mccadden

We had our hot water tank go out last weekend. Haller Enterprises was recommended to us. The Technician Rocci Shuima was awesome to work with, very friendly, Knowledgeable and on time. He explained everything clearly, handled the install efficiently and made sure everything was running perfectly and kept the area very clean. We could not be happier with the install. Definitely recommend Haller Enterprise and Rocci!

M Rutkowski

Rob Royer

Called Haller cuz I had a problem with my generator they came out the same day and fixed it

Jill Pisano

The employer wasn’t able to repair our problem w the kitchen sink, so he referred us to Agentis Kitchen & Bath, bc we hv granite countertops, which no plumber is permitted to drill. It’s not in their job description. I paid $79.00 via check for the home visit.

Fred Carrer

The technician's new the job,
very courteous and thoughtful and played with our puppy which was a good thing

Shawn Sottosanti

Called Haller for an emergency service. They were able to get us on the schedule for Sunday which I know is very difficult to do. We were able to have someone come out and diagnose the problem before they could arrive and had to cancel on them last minute. I do truly appreciate their concern and customer service as we have animals at home that was our primary worry. We’re in the market for a new AC Unit this summer and will definitely remember Haller because of this
