Ductless heating & cooling
Comfort for the Rooms Ducts Can't Reach
Third-floor bedrooms, finished basements, additions, rowhomes with no ductwork at all — mini splits heat and cool them beautifully, room by room.
Zoned, ductless, efficient
Philly's housing stock was built before ductwork. Mini splits solve that.
Rowhomes, twins, converted flats — much of Philadelphia was never built for central air, and retrofitting ducts means tearing open walls. A ductless mini split skips all of it: a slim outdoor unit, discreet indoor heads, and a three-inch wall penetration per room. Full heating and cooling, no demolition.
Each indoor head is its own zone with its own remote — cool the bedroom at night without paying to cool the whole house. Modern cold-climate mini splits heat efficiently through Philly winters too, making them a genuine one-system answer for additions, top floors, garages, and whole small homes.
AJM installs and services the major mini split brands, sizes each zone to its actual room, and runs linesets clean and hidden. A mini split install should look like it grew there — not like an afterthought bolted to the wall.
What's included
Ductless from design to service
One room — an addition, attic office, or garage — conditioned independently and efficiently.
One outdoor unit driving up to five indoor heads, each with its own thermostat.
Mini splits rated for real winter heating — not just summer cooling with a heat mode.
Error codes, leaks, and failed boards diagnosed and repaired on all major brands.
Head deep-cleaning and coil service that keep efficiency high and air healthy.
For homes with no ducts at all — a zoned system replacing radiators or window units entirely.
Know the warning signs
Six signs a mini split is your answer
The third-floor bedroom that's an oven in July and an icebox in January — one head fixes it.
Loud, inefficient, insecure, and blocking your windows. A mini split retires all of them.
Extending ductwork to new space is expensive and often underperforms. Ductless is built for this.
Radiator-heated rowhome with no cooling? Ductless adds AC without opening a single wall.
Zoning ends the war. Everyone sets their own room.
Cooling the whole house to use two rooms is expensive. Zones cool only what you're using.

How it works
From site visit to zoned comfort
- 1Room-by-room assessment
We measure each space and its real load — sun, insulation, use — and design zones to match.
- 2Placement & quote
Head locations, lineset routing, and pricing agreed before anything is drilled.
- 3Clean installation
Most single-zone installs are one day; multi-zone typically two. Linesets run hidden.
- 4Commissioned & tuned
Every zone tested heating and cooling, refrigerant verified, controls walked through.
Common questions
Ductless Mini Split Systems FAQs
Do mini splits really heat through a Philly winter?
Cold-climate models do — they're rated to well below zero and heat efficiently through everything our winters throw at them. We spec cold-climate units whenever heating is part of the job.
How visible are the indoor units?
The standard wall head is a slim white unit high on the wall. Where looks matter more, ceiling cassettes and floor consoles are available — we'll show options during the site visit.
Are mini splits noisy?
The indoor heads run at whisper levels — quieter than a refrigerator. The outdoor unit is dramatically quieter than a traditional condenser.
What maintenance do they need?
Rinse the filters monthly (two minutes, no tools) and get a professional deep clean annually. Skipping the cleanings is the number-one cause of efficiency loss and musty smells.
