Short answer: A ductless mini-split is the most practical way to cool and heat older Paradise homes that have no ductwork, rental units and casitas near UNLV, room additions, garage conversions, and west-facing rooms your central AC never quite reaches. The Cooling Company installs single-zone and multi-zone inverter heat-pump systems, sized with a Manual J load calculation, with a clean line set, proper electrical, and quiet indoor heads. We have been licensed in Nevada since 2011 (C-21 #0075849 and C-1D #0078611). Call (702) 567-0707 for a Paradise mini-split estimate.
Paradise is one of the oldest and densest parts of the Las Vegas valley, wrapped around UNLV, McCarran (Harry Reid) International, the convention corridor, and the south end of the Strip. A lot of the housing here went up decades ago: small single-family homes, duplexes, fourplexes, and converted units rented to students, hospitality workers, and travelers. That older stock is exactly where ductless mini-splits do their best work. When a home was never built with central ductwork, or when one stubborn room runs ten degrees hotter than the rest of the house, running a refrigerant line to a wall-mounted head solves the problem without tearing the place apart.
Where ductless makes the most sense in Paradise
We see the same handful of situations over and over in this part of the valley, and ductless answers all of them:
- Older homes with no ductwork. Many Paradise homes used wall or floor furnaces and window units their whole life. Retrofitting full ducts into a finished home means cutting into ceilings and soffits and losing closet space. A mini-split skips all of that.
- Rental units, duplexes, and fourplexes. Near UNLV and the airport, landlords need each unit to control its own comfort and pay for its own usage. A separate mini-split per unit gives tenants independent control and replaces the loud, leaky window units that are still common in older rentals.
- Casitas, ADUs, and guest quarters. A detached casita or accessory dwelling rarely justifies extending the main system. One outdoor unit and one head climate-control the space on its own.
- Room additions and bonus rooms. When a home grows, the original AC was sized for the original square footage. Rather than overload it, a dedicated zone keeps the new space comfortable without starving the rest of the house.
- Garage conversions and home offices. Converting a garage into a bedroom, gym, studio, or office is popular here. Garages have almost no insulation and brutal afternoon heat gain, so they need their own cooling and heating.
- Hot west-facing rooms. A bedroom or living room that bakes in the afternoon sun often defeats a central system, which has to average the whole house. A single head turns that one room into its own zone.
- Small offices and light commercial. Storefronts and suites along the corridor use ductless to cool a space precisely without a rooftop unit.
How a ductless mini-split actually works
A ductless system has two main pieces: an outdoor condenser/heat pump and one or more indoor heads (also called air handlers). They connect through a slim line set, a bundle that carries refrigerant lines, a condensate drain, and control wiring, that runs through a roughly three-inch hole in the wall. There is no bulky sheet-metal ductwork, which is the whole point. Refrigerant moves heat directly between the outdoor unit and each indoor head, so you avoid the energy that central systems lose pushing air through long duct runs.
Indoor heads are usually mounted high on a wall, though ceiling-cassette and floor-mounted styles exist for rooms where a wall unit will not work. Each head has its own thermostat and remote, so every zone is set independently.
Single-zone vs multi-zone
A single-zone system pairs one outdoor unit with one indoor head. It is the right call for a casita, a converted garage, a home office, or one problem room. A multi-zone system connects several indoor heads to a single outdoor unit, which lets you condition a whole no-duct house, or several rooms, while running just one condenser outside. For a Paradise duplex or a three-bedroom home without ducts, multi-zone is often the cleanest path to whole-home comfort.
Why inverter heat pumps beat window units
The window units still rattling away in a lot of older Paradise rentals are the comparison that matters most. Modern ductless systems use inverter-driven compressors that ramp up and down to match the load instead of slamming on and off. That delivers high efficiency (strong SEER2 cooling and HSPF2 heating ratings) and far steadier temperatures than a window unit can manage. The difference shows up on the power bill during a Las Vegas summer, where the AC runs for months straight.
Because they are heat pumps, these systems also heat. Paradise winters are mild, and a mini-split heat pump covers our heating season efficiently without a separate furnace, which is ideal for an addition or a casita that has no gas line. Add quiet operation (indoor heads run far quieter than a window unit or a portable), real zoned control, and no window blocked by a box, and the upgrade is easy to justify.
When ductless beats adding ductwork to an old home
Retrofitting ducts into a finished older home is invasive and expensive. You lose ceiling height, closet depth, and often pay to patch and repaint everything the install touched. A ductless system reaches the same rooms with a slim line set and a small wall penetration, and it adds zoning a single central system cannot. When the bones of the house were never built for ducts, ductless is the smarter spend.
What a professional install includes
Mini-splits are simple to live with but unforgiving when installed poorly. A botched line set, an undersized unit, or a bad electrical run shows up as weak cooling, short cycling, or refrigerant problems down the road. Our Paradise installs include:
- Manual J sizing. We calculate the actual heat load of each space, factoring square footage, insulation, windows, sun exposure, and ceiling height, so the system is sized right. Oversized units short cycle and waste energy; undersized units never keep up in July.
- Clean line-set routing. We plan the path from the outdoor unit to each head, properly evacuate the lines, and protect the run with line-set cover where it is visible.
- Solid mounting. The condenser sits on a level pad or wall bracket, and each indoor head is mounted securely and pitched for proper condensate drainage.
- Correct electrical. We install the dedicated circuit, disconnect, and whip the system needs, all to code.
- Commissioning. We pressure-test, pull a vacuum, verify the charge, and confirm every zone heats and cools before we leave.
Our 5-step ductless process
- In-home assessment. We walk the home, identify which rooms need zones, and weigh single-zone versus multi-zone for your layout and budget.
- Load calculation and proposal. We run Manual J on each space and recommend the right number of heads, capacity, and placement, then give you a clear written estimate.
- Schedule and prep. We confirm equipment, line-set routing, and the electrical plan, and set an install date that works for you or your tenants.
- Installation. We mount the outdoor unit and indoor heads, run and protect the line set, wire the electrical, and seal the wall penetration cleanly.
- Commissioning and walkthrough. We test every zone, verify the charge, and show you how to run the remotes and keep the filters clean.
Ductless mini-split FAQs for Paradise homeowners
Will a ductless mini-split cool my whole house or just one room?
Both are possible. A single-zone system handles one room, a casita, or a converted garage. A multi-zone system connects several indoor heads to one outdoor unit and can cool and heat a whole home that has no ductwork. We size the system to your goals during the in-home assessment.
How many indoor heads do I need?
It depends on your floor plan and how open it is. Open layouts may need only one head per area, while a home with several closed-off bedrooms typically needs a head in each room that has to stay comfortable. We determine the exact count with a room-by-room load calculation rather than a guess.
Is a mini-split really better than the window units in my rental?
Yes, on efficiency, comfort, and noise. Inverter heat-pump mini-splits modulate to match the load instead of cycling hard on and off like a window unit, so they hold temperature better and use less power across a long Las Vegas summer. They also run much quieter and do not block a window.
Does a ductless system heat as well as cool?
Yes. These are heat pumps, so they reverse to provide efficient heating. For Paradise winters they cover the heating season comfortably, which makes them a strong fit for additions and casitas that have no furnace or gas line.
How long does a ductless installation take?
A single-zone install is often completed in a day. Multi-zone systems with several heads can take a day or two depending on line-set routing and electrical work. We give you a realistic timeline with your proposal so you can plan around it.
