Heating, cooling and plumbing for Millburn and Short Hills homes
Short Hills is a section of Millburn Township, in Essex County. The township was formed in 1857 from part of Springfield, and much of Short Hills grew out of the planned community Stewart Hartshorn started in 1874. Today the Short Hills Park Historic District covers roughly 1,000 acres, with 266 designated properties built between about 1875 and 1940. Millburn’s Wyoming Historic District has 79 properties, mostly modest late-1800s homes on 50-foot lots.
The rest of the housing stock is old too. Millburn’s 2018 Housing Element, citing American Community Survey 2012–2016 data, reports that about 40.6% of the township’s housing units were built before 1939, and roughly 69% were built before 1960. Houses from those decades were usually built around a boiler and radiators, not ductwork, and many have been remodeled several times since. That history shows up in the work we do here:
- Steam and hot-water boilers still heating original radiators
- Central air added later, with ducts squeezed into attics and closets
- Cast-iron drain lines and older sewer laterals running under mature trees
- Galvanized or mixed supply piping left over from past renovations
- Water heaters and sump pumps working hard in finished basements
AC replacement and AC repair in Millburn and Short Hills
When a central air system stops keeping up, the first question is usually whether to repair it or replace it. We look at the system’s age, its refrigerant type, how often it has needed repairs and whether the ductwork is sized for the house. Then we lay out the options so you can decide. If a repair makes sense, see our AC repair service. If it’s time for new equipment, our AC installation team sizes the system to the house rather than to the old unit.
Many older Short Hills and Millburn homes have no ductwork at all. For those houses, ductless mini-split systems and heat pumps can add cooling, and often efficient heating, without opening up plaster walls for new ducts. Utility rebates may apply to some equipment; see our savings and rebates page for current details.
Furnace, boiler and steam heating service
We repair, maintain and replace every common type of heating system found in the township, from gas furnaces to hot-water and steam boilers. For no-heat calls and noisy or short-cycling systems, see furnace repair and boiler repair. If you’re weighing a new system, our boiler installation and furnace installation pages explain the process, and our article on heating installation options for Millburn homes walks through the choices in more detail.
Steam heat in particular needs a technician who knows it. Sizing, venting and water-level problems are common in older steam systems, and getting them right makes a big difference in comfort and noise.
Plumbing for Millburn and Short Hills
Millburn’s public water comes from New Jersey American Water’s Short Hills System, which combines water from its own wells with water purchased from other suppliers, according to the system’s 2025 annual water quality report. Once that water reaches your house, the pipes, fixtures and water heater are what we work on. Our plumbers handle:
- Drains and sewer lines. Root intrusion and old cast iron are common causes of backups here. See our guide to clogged drain repair in Short Hills, plus drain cleaning and sewer camera inspection.
- Water heaters. Tank and tankless repair and replacement. Read about water heater repair or replacement in Millburn and how to tell when a Short Hills water heater needs service.
