Stay Cool in Rochester—The Smart Way
When summer heat and humidity hit Rochester, keeping your home comfortable becomes a top priority. But here’s the big question many homeowners face: Should you go with central air or ductless mini-splits?
Both systems have their advantages—and depending on your home’s setup, cooling needs, and budget, one might be a much better fit than the other. In this post, we’ll break down the differences in cost, efficiency, comfort, and installation to help you make the right decision. And if you’re ready to upgrade or install a new system, the pros at Trident Heating & Cooling are here to help.
What’s the Difference?
Central Air Conditioning
Central air uses one main system (typically in your basement or attic) to cool and distribute air through ductwork into every room of your home. It’s ideal for homes that already have ducts in place.
Key Features:
-
Uses a single thermostat for temperature control
-
Air is pushed through vents via ductwork
-
Requires filters and duct cleaning for maintenance
Ductless Mini-Splits
Mini-splits consist of one or more indoor air-handling units connected to an outdoor compressor. Each indoor unit is mounted on a wall or ceiling and cools a specific zone or room.
Key Features:
-
No ductwork required
-
Zoned temperature control (each room can be set independently)
-
Great for additions, renovations, or older homes
Installation: What to Expect
Central Air Installation
-
Best for homes with existing ductwork
-
Installation takes a few days on average
-
More invasive if ducts need to be added
-
Costs range from $6,000–$12,000+, depending on home size and duct complexity
Ductless Mini-Split Installation
-
Quicker and less disruptive
-
Ideal for homes without ductwork
-
Just a small hole is needed for refrigerant lines
-
Single-zone systems cost around $3,000–$5,000; multi-zone setups can reach $15,000
If your home lacks ductwork, going central could mean a full remodel. In that case, a mini-split system is a no-brainer.
Energy Efficiency & Operating Costs
Central Air
-
Typically rated at 16–20 SEER
-
Can lose up to 30% of cooling efficiency through duct leaks
-
Uses more energy to cool the entire house evenly
Ductless Mini-Splits
-
Often rated at 20+ SEER, with higher efficiency
-
No duct losses = more direct cooling
-
Zoned systems let you cool only the rooms you use
Winner for Efficiency: Ductless mini-splits. They’re often 20–30% more efficient, especially in homes with no existing ductwork.
Comfort & Climate Control
Central Air
-
Consistent temperature across the whole home
-
Can’t easily accommodate different comfort levels in different rooms
-
Thermostat placement can affect performance
Ductless Mini-Splits
-
Customize temperature room-by-room
-
Perfect for families with different comfort preferences
-
More responsive in Rochester’s humidity-prone summers
Bonus: Mini-splits are also excellent at dehumidifying the air, which is a big win during muggy Upstate NY days.
Aesthetics & Noise Levels
Central Air
-
Vents are discreet and built-in
-
Equipment is located away from living spaces
-
Runs quietly if properly maintained
Ductless Mini-Splits
-
Indoor units are visible but sleek
-
Mounted high on walls or recessed in ceilings
-
Extremely quiet operation—great for bedrooms or nurseries
If a minimalist aesthetic is a priority, central air may edge out. But today’s ductless units are far from bulky or intrusive.
Maintenance & Lifespan
Both systems can last 15–25 years with proper care.
Central Air
-
Annual tune-ups recommended
-
Duct cleaning may be necessary every 3–5 years
-
Filter changes every 1–3 months
Ductless Mini-Splits
-
Monthly filter cleaning (can be done at home)
-
Professional servicing once per year
-
No ducts = no duct cleaning
