The Smith G Series typically costs $3,000 - $5,200 for a complete installation in Nassau County, NY. This includes the boiler unit, professional installation by EPA-certified technicians, permits, and a standard warranty.

It is rated at 86% AFUE. Key features include High-capacity cast iron and Heavy construction. It is particularly well-suited for large multi-family or commercial-residential.

What is the warranty on the Smith G Series?

Smith Cast Iron Boilers provides a 2 years parts warranty and 25 years on the heat exchanger. For the best warranty protection, we recommend registering your boiler within 60 days of installation. Our installations include a workmanship guarantee on top of the manufacturer warranty.

How long does the Smith G Series last?

With proper maintenance, the Smith G Series should last 15-25 years or more. We recommend annual tune-ups to maximize lifespan and maintain peak efficiency.

Are current utility or manufacturer programs available for the Smith G Series?

An AFUE rating does not automatically establish program eligibility. Current utility or manufacturer programs may change and must be confirmed in writing for the customer, exact equipment, project scope, contractor, installation date, funding availability, and current rules before an incentive is reflected in the quote.
