Anderson Water-Power-Air is a family-owned business serving New York State, providing the highest-quality products and service available in the industry.

"Five minute repair that could have been explained to me on phone. Instead they send a repairman to literally tighten a screw and charge me $179 for a service call. Less than five minutes work and the screw came loose again, so I put thread lock on the screw and permanently fixed the problem. This probably should have been done during installation. This sort of work is a ripoff and I will never call for service again. The lifetime warranty is on the equipment, they will still hit you hard for a service charge. I fully retract my previous evaluation. This not a service, it is a money machine designed to get every penny they can, even if the equipment was done poorly. (a screw that keeps backing out is always locktited in the machine world, I know, I did it for years)."

"I paid Jim nearly $400 to replace a sump pump. A few months later it was running constantly and he did come out twice.. for 2 minutes each time and did NOTHING! I had to pay Roto Rooter who diagnosed the issue in the first minute as a problem with the check valve. After coming out, Jim refused my calls and didn’t return any messages. I had referred many people to his business. Now I will let everyone know his true lack of follow up and knowledge since he had no idea of what was wrong. Don’t waste your money here!"
