Comfort, Zoned to Every Room.
Ductless mini-splits and heat pump systems, sold, sized, and installed across the greater Sacramento region. No ductwork required, no wasted capacity, no finger-pointing between the shop that sold the unit and the crew that installed it. Every project begins with a free in-home assessment and ends with a system commissioned zone by zone.
From a single stubborn bedroom to a five-zone whole-home retrofit, every system in the Citadel catalog is sold direct, sized to the house, and installed by Sacramento-based crews.
A wall-mounted head unit and a matched outdoor condenser, sized to the exact room. The fix for the back bedroom that never cools, the garage gym, the ADU, one three-inch wall penetration and no ductwork.
One outdoor unit feeding up to five indoor heads, each with its own set point. Line-sets routed clean, condensate managed properly, every zone balanced on commissioning day.
One inverter-driven system that cools through a Sacramento July and heats through a Delta-fog January. No gas line, no separate furnace, no duct losses.
The unit and the install come from the same house. We stock and sell Senville systems direct, one point of accountability from the box to the commissioning walkthrough.
Sacramento summers run past a hundred degrees, then the Delta breeze drops the evening twenty degrees in an hour. Inverter-driven ductless systems are built for exactly that swing: they modulate continuously, holding the room within a degree while sipping power.
And this is an old-housing-stock town. Most Midtown four-squares and Land Park cottages were never built with ductwork, and retrofitting ducts means tearing open ceilings. A ductless system respects the house: one small penetration per head, original plaster untouched.
| Ductless Mini-Split | Central Ducted | Window / Portable | |
|---|---|---|---|
| Install footprint | One 3-inch wall penetration per head | Full duct network through attic and walls | None, but takes the window |
| Room-by-room control | Per-head zoning built in | One thermostat for the whole house | Single room only |
| Noise | Whisper-quiet indoor heads | Air handler rumble and vent hiss | The loudest option in the room |
| Efficiency | Highest, inverter-driven, no duct losses | Loses up to a quarter of output through ducts | Lowest efficiency per BTU |
| Best for | Zoned comfort, older homes, additions | Homes with healthy existing ductwork | Stopgaps and rentals |
Single room or whole home, every Citadel install runs the same rail, built around the realities of Sacramento construction, panel capacity, and summer heat.
A Sacramento-based specialist walks the home with you: measures each space, checks the electrical panel and breaker capacity, and talks through where heads should live and what each zone needs to do. Free, and no obligation to move forward.
Head count, capacity, condenser placement, and line-set routing designed to the home, not a catalog default. You get a fixed quote covering equipment and installation before any work is scheduled.
The crew mounts heads, sets the condenser, routes and insulates line-sets, pulls vacuum, and charges the system to spec. Most single-zone installs finish in a day; multi-zone systems typically run one to two days.
Every zone is run, tested, and balanced before the crew leaves, and you walk the whole system with them: modes, remotes, filters, and maintenance rhythm. The install is not done until you have driven it yourself.
Citadel installs HVAC across the greater Sacramento region, homes, custom builds, ADUs, and remodels. If your project sits in any of these areas, our team can be on-site for a free quote within a week.
The questions Sacramento homeowners ask most before going ductless, answered so you can spec with confidence.
Talk to Our TeamNo. Ductless systems need only a three-inch wall penetration per head, which is what makes them ideal for older Sacramento homes without existing ducts.
One head per area you want to control independently. A single outdoor unit can feed up to five heads; the free in-home assessment confirms count and capacity.
Yes. We stock and sell Senville systems directly through our HVAC collection, so the unit and the install come from the same house with one point of accountability.
Most single-zone installs finish in a day. Multi-zone systems typically run one to two days depending on head count and line-set routing.
Yes. Sacramento winters are mild by heat-pump standards; modern inverter systems heat efficiently well below any temperature this valley sees.
Inverter-driven systems modulate instead of cycling, so they hold temperature using a fraction of the power of window units or aging central systems. Exact numbers depend on zones and usage, and we walk them with you at the assessment.
