Branchburg spreads across the Raritan and its North Branch, cut through by Route 22 and I-78, with a community college campus and open farmland still mixed into the map. One road here can hold a working farmhouse, a 1970s ranch and a 2000s colonial, and each of those came with a different generation of heating, cooling and water equipment. We work on all three in a given week, which means the first thing we do is find out what you actually have.
Heights Plumbing, Heating & Cooling is a family-owned, licensed and insured plumbing and HVAC company serving the township of Branchburg in Somerset County, New Jersey. 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 Branchburg Homes & Buildings
- Farmhouses and converted older buildings sit alongside newer subdivisions, so neighboring houses often have nothing in common mechanically.
- Properties beyond the public water and sewer lines run on private wells and septic, and hard well water is the usual reason water heaters, valves and fixtures wear out early.
- Open lots and long duct or pipe runs make heat loss and heat gain calculations genuinely worth doing before anyone sizes a replacement system.
Sections of Branchburg we serve include North Branch, Neshanic Station, along with every other part of the township.

Branchburg Plumbing & HVAC FAQs
We are on a well and our water leaves spots on everything. What fixes that?
Spotting and scale point to hardness, which a properly sized softener handles. We test the water first, because sediment, iron and odor each need a different piece of equipment and a softener alone will not solve them.
Does well water shorten the life of a water heater?
Untreated hard water does, because scale builds on the tank bottom and the element or burner has to work through it. Treating the water and flushing the tank on a schedule makes a real difference to how long it lasts.
Our farmhouse has been added onto twice. Can you make the heating even?
Usually yes, and the answer is rarely a bigger furnace. Additions are often fed by ducts or piping sized for the original house, so we measure airflow and temperatures room by room and fix the distribution before we talk about equipment.
