Lawrence Township runs from the Trenton line up Route 206 through the Lawrenceville village and out along the Route 1 corridor, where Quaker Bridge Mall, office parks and the Rider University campus sit. The housing is a genuine mix — old farmhouses and Victorians along 206, large postwar and 1970s subdivisions through the middle, and condominium and townhouse complexes closer to Route 1. Which of those three an address belongs to decides how we plan the job.
Heights Plumbing, Heating & Cooling is a family-owned, licensed and insured plumbing and HVAC company serving the township of Lawrence Township in Mercer County, New Jersey. ZIP 08648. 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 Lawrence Township Homes & Buildings
- The Route 1 side has a heavy share of condominium and townhouse units where the equipment lives in a closet or on an attic platform, so access is the first thing we look at.
- Subdivision houses from the 1960s and 1970s are on their third round of equipment, and the original duct layout rarely matches the addition somebody built later.
- Finished basements are the norm in the newer parts of town, which is why we would rather locate a hidden leak with test equipment than start opening ceilings.
Sections of Lawrence Township we serve include Lawrenceville, Slackwood, Eldridge Park, along with every other part of the township.

Lawrence Township Plumbing & HVAC FAQs
Our attic air handler is dripping onto the ceiling below. What is going on?
That is almost always a plugged condensate drain or a rusted drain pan, and the float switch that should have shut the system down has either failed or was never installed. We clear the drain, address the pan, and make sure a working safety switch protects the ceiling next time.
Can you handle a restaurant or retail space along Route 1?
Yes. Grease-line and main-line backups, rooftop heating and cooling units, and commercial water heaters are routine work for us, and we can come in outside of business hours where the schedule allows.
What does No Worries Pricing actually mean?
You get the price before the work starts, in writing, and that is the price — no surprise add-ons at the end. First-time customers also get $25 off, and financing through Synchrony is available on larger jobs.
