Franklin is a compact borough with a mining past — the zinc deposits worked here are why the Franklin Mineral Museum sits in town and why the place is known for its fluorescent minerals. Route 23 runs straight through the middle, and the housing is mostly older: mining-era frame homes on small lots, with newer construction at the edges. Houses of that vintage tend to keep their original supply piping and heating layout until something finally forces the issue.
Heights Plumbing, Heating & Cooling is a family-owned, licensed and insured plumbing and HVAC company serving the borough of Franklin in Sussex County, New Jersey. ZIP 07416. We offer same-day service, on-time arrival and upfront No Worries Pricing on every job, and we handle residential and commercial work.
What We See in Franklin Homes & Buildings
- A good share of the housing predates modern plumbing standards, so galvanized supply lines and undersized service piping turn up regularly.
- Small lots and low basement clearance limit equipment access, which shapes how a boiler or water heater replacement gets planned.
- The built-up part of the borough is served by public water and sewer, unlike much of the rural township land around it.

Franklin Plumbing & HVAC FAQs
Our older Franklin house still has galvanized water pipes. Does all of it have to go?
Rarely all at once. Galvanized pipe scales shut from the inside, so we check flow and pressure and usually repipe the worst runs first — typically the branches feeding the upstairs bathrooms.
Do we need a permit to swap out a furnace here?
Yes. Furnace, boiler and water heater replacements are permitted work in New Jersey. We file the permit with the borough, install to code, and stay with the job through the inspection.
Is a high-efficiency boiler worth it in a house this small?
Often, but only if it is sized to the house. We run a heat loss calculation rather than matching the old unit's rating, because oversized equipment short-cycles and costs more to run than it should.
