Ductless Mini-Splits: The Best AC Solution for Older South Jersey Homes
Why ductless mini-splits are often the perfect retrofit for older Mount Ephraim, Audubon, and Haddon-area homes that were never built for central air.
South Jersey is full of beautiful older homes — 1920s bungalows in Haddon Heights, brick rowhomes in Audubon, plaster-walled Cape Cods in Mount Ephraim. They have one thing in common: they were never designed for central air conditioning. Here's why ductless is usually the answer.
The Problem with Forcing Central Air Into an Old Home
To add traditional central A/C, contractors typically have to bury ducts in soffits, drop ceilings, or carve up the second floor. It's expensive, it's ugly, and it almost always leaves at least one room uncomfortable.
Why Ductless Just Works
- No ductwork needed — refrigerant lines run through a 3-inch hole in the wall
- Each zone has its own thermostat, so the back bedroom can finally be the right temperature
- Modern units are heat pumps, so you get heating in shoulder seasons too
- SEER2 ratings of 22+ mean they sip electricity
- They're quiet — the loudest sound is often the refrigerator across the room
Where It Makes the Most Sense
- Finished attics that bake in summer
- Additions where the existing system can't reach
- Sunrooms and 3-season rooms
- Bonus rooms over garages
- Whole-home retrofits in homes without existing ducts
What It Costs
- Single-zone (one room): $4,500 – $7,500 installed
- Two-zone: $7,000 – $11,000 installed
- Whole-home multi-zone (4–5 heads): $14,000 – $22,000 installed
What About the Indoor Heads — Are They Ugly?
Modern wall units are slim and white and disappear into the wall above a doorway. We also install ceiling cassettes and concealed ducted heads when wall-mount isn't an option. We'll walk the house with you and plan placements.

Frequently asked
How long do ductless mini-splits last?+
With basic annual maintenance, 18–22 years. They're built with fewer moving parts than central systems and they age very well.
Can one outdoor unit handle the whole house?+
A single outdoor unit can usually run 2 to 8 indoor heads, depending on the model. We size it based on total cooling load, not just zone count.
Do mini-splits work for heating in NJ winters?+
Modern cold-climate heat pumps work efficiently down to about 5°F, which covers nearly every NJ winter day. For the handful of brutal nights, electric resistance backup or a small gas furnace handles it.
