Smithtown Boiler Repair & Service FAQ

Should I replace my old boiler?

If it's cast iron and still efficient enough, it may have years left. If it's leaking or the repairs keep stacking up, a high-efficiency boiler can cut fuel use.

Why are my radiators cold at the top?

That's trapped air. Bleeding the radiator usually fixes it.

Do you really cover Nissequogue?

Yes. Coming in on the LIRR Port Jefferson branch corridor, give or take a deli stop. Circulator? Zone valve? If you can tell us what this is, we'll do the whole job free. (It's a pump.)
