Hanover Township covers the Whippany and Cedar Knolls sections and the office and light industrial parks that grew up around Route 10 and Route 287. Residential streets here are mostly postwar capes, ranches and colonials, with newer townhouse and condominium developments filling in former industrial land. The Whippany River crosses the township, and the flatter ground near it drains slowly.

What We See in Hanover Homes & Buildings
- Whippany and Cedar Knolls are sections of the township rather than separate towns, and both carry a similar mix of 1950s-70s housing with later additions.
- Townhouse and condo units built on redeveloped parcels often have the furnace and water heater in a utility closet, where clearance and venting rules drive what can be installed.
- Central air added to older capes usually runs through undersized ducts in a knee wall, which shows the up-and-down temperature swings homeowners notice most in August.
- Flat, low ground near the Whippany River means some basements and crawl spaces need pump and drainage attention after heavy rain.
Sections of Hanover we serve include Whippany, Cedar Knolls, along with every other part of the township.

Hanover Plumbing & HVAC FAQs
Can you replace equipment in a townhouse utility closet in Whippany or Cedar Knolls?
Yes, and the closet is usually what determines the model. We measure the clearances and the existing vent before quoting so the new unit fits, vents correctly and can still be serviced without dismantling the closet.
Do you service rooftop HVAC units on smaller commercial buildings?
We do. Rooftop units are common on the office and retail buildings here, and we handle service, maintenance and replacement, including the curb and electrical side of a changeout.
Our 1960s cape has terrible airflow upstairs. Is new equipment the answer?
Rarely on its own. In a cape the ducts serving the upper floor are usually the bottleneck, so we measure static pressure and airflow first. Fixing the duct and return path often does more than a larger unit would.
