Lopatcong Township climbs the hills just above Phillipsburg, so it runs from older streets that feel like an extension of the town to newer subdivisions and townhouse developments on the high ground. Homes closer to the Phillipsburg line tend to be older with radiator heat and original piping, while the newer sections have forced air and equipment that is now a decade or two old. Route 22 and Interstate 78 put the township within easy reach for our trucks.
Heights Plumbing, Heating & Cooling is a family-owned, licensed and insured plumbing and HVAC company serving the township of Lopatcong in Warren County, New Jersey. ZIP 08865. 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 Lopatcong Homes & Buildings
- Elevation changes across the township mean the houses at the top of a hill feel supply pressure differently than those at the bottom, which is worth checking before assuming a fixture or valve is at fault.
- The newer subdivisions were built out in phases, so whole streets reach the end of their original furnace, condenser and water heater life within a few years of each other.
- Older homes near the Phillipsburg edge still run boilers and radiators, and adding cooling to them usually means a ductless system rather than new ductwork.

Lopatcong Plumbing & HVAC FAQs
Our house is on a hill and the pressure feels weak upstairs. What causes that?
Elevation costs you pressure on the way up, and an older service line or a partly closed main valve makes it worse. We take a pressure reading at the meter and at an upstairs fixture so you can see where the loss actually happens before spending money on a pump.
We have radiators and no ductwork. Can we get central air?
You can get whole-house cooling, just not through ducts you do not have. Ductless mini splits handle this well in older Lopatcong homes, and they let you cool the rooms you actually use without opening up plaster.
Do you work in the townhouse developments here?
We do. Townhouses have their own constraints — closet or attic air handlers, shared walls and limited condenser placement — and we size and lay out the equipment around them rather than forcing a standard installation.
