A new AC system in West Hollywood typically runs $3,500 to $7,500, with heat pump and ductless mini split installations landing in the same range, and we give you the written price before any work starts. Our crews work in West Hollywood every week, from the high-rises on Sunset to the courtyard buildings off Santa Monica Boulevard, and we know what this city’s housing stock demands. If you’re weighing a central air install, a heat pump upgrade, or a ductless system for an older building, call (213) 531-5904. A live person answers 24 hours a day, seven days a week.
West Hollywood is not like the rest of Los Angeles. The buildings are older, tighter, and often protected by historic designation. A one-size-fits-all install won’t pass inspection and it won’t keep you cool the way it should. That’s why we start every job with a load calculation and a straight conversation about what will actually fit in your space, and we put the price on paper before a single tool comes out.
Why Cold Harbour Heating and Air Los Angeles Is West Hollywood’s Preferred AC Installation Company
We’ve been installing and servicing AC systems since 2003, and West Hollywood neighbors have come to know our uniformed, background-checked technicians by name. Much of our work in the area is repeat business and direct referrals. When a courtyard building on Harper Avenue needs a ductless retrofit, or a hillside home off Doheny Drive needs a multi-zone heat pump, we get the call because the last job held up.
Our AC Installation team regularly works with the materials found in 1920s and 1930s West Hollywood buildings: lathe-and-plaster walls, flat roofs, tight basements, and no space for conventional duct runs. That local experience is the difference between an estimate that makes sense and one that falls apart on the first day of the job.
We back every installation and repair with the 365-Day Done Right Promise. If anything fails within a full year, we come back and correct it at no charge, and that promise is written down before the technician leaves. We answer the phone around the clock, because a cooling failure during a Santa Ana heat spike in September is not something you should have to wait until Monday to address.
You’ll find the West Hollywood locations we serve span the entire city, from the Norma Triangle to West Hollywood West. If you want a crew that already knows your building type, call (213) 531-5904.

Heat Pump Installation in West Hollywood
Heat pump installation in West Hollywood makes particular sense for homes and condos where the city’s push toward all-electric buildings means replacing a gas furnace with electric heating and cooling in one unit. The job involves removing the old furnace or air handler, setting a new outdoor condensing unit, and connecting it to an indoor air handler or, in ductless applications, to wall-mounted heads. A full heat pump installation in West Hollywood runs $3,500 to $7,500 depending on capacity, zoning, and whether ductwork already exists.
West Hollywood’s mild climate means a high-efficiency heat pump rarely strains. Cooling load stays low because we only get three to five days over 100°F in a typical year, but the urban canyon effect on streets like Kings Road and Wetherly Drive means west-facing units can trap afternoon heat. A variable-speed heat pump handles that swing better than a single-stage system, holding temperature without short-cycling.
Why West Hollywood Retrofits Go Electric
Many 1920s courtyard buildings still have original gravity furnaces sitting in tiny basement closets. Replacing those with a conventional furnace and duct system usually means opening walls and losing closets. A ducted heat pump with a slim vertical air handler often fits where the old gravity unit sat, especially if we route flexible duct through the same chases that once held the original registers.
Commissioning a Multi-Zone Heat Pump
Our crew installed a multi-zone Daikin heat pump for a hillside home off Doheny Drive where three concealed ducted air handlers went into existing closets. The condenser was matched to a 3-ton load calculation and we held static pressure under 0.5 inches. The owner keeps temperature-sensitive art, so we set the blower for continuous low-speed circulation and verified the refrigerant charge to the ounce before final commissioning. That’s how a complex system actually delivers what the brochure promises.
Ductless Mini Split Installation in West Hollywood
Ductless mini split installation in West Hollywood is often the only practical answer for older units, historic buildings, and rooms that were never designed for central air. The job involves mounting one or more indoor wall units, running a small refrigerant line set through an exterior wall, and connecting them to a quiet outdoor condenser. Typical ductless mini split installation in West Hollywood runs $3,500 to $7,500 depending on how many indoor heads the layout requires.
In the Norma Triangle and Boystown, we see 1920s courtyard apartments where original gravity furnaces sit in basements so small they leave almost no room for a conventional air handler. The fix is often a slim-duct or fully ductless system threaded through closets that once doubled as elevator shafts. That arrangement preserves the historic character of the building while delivering real cooling to each unit.
Noise Control on Tight Lots
West Hollywood enforces strict noise limits, and a condenser mounted on a small patio or side yard can cause real friction with neighbors. We use isolation pads, sound blankets where appropriate, and location placement that accounts for bedroom windows and property lines. The quietest systems from Daikin and Mitsubishi-style units run below 50 decibels, which is quieter than most conversations.
Zoning for Additions and ADUs
West Hollywood encourages accessory dwelling units, and a ductless mini split is often the fastest way to condition a converted garage or rear unit without extending the main system. Each indoor head gets its own thermostat, so the main house and the addition stop fighting over one setpoint. That independent zoning also helps homes with west-facing glass, where a single zone can’t address afternoon heat gain in one room without overcooling the rest.
Trusted Brands We Service in West Hollywood
Our technicians are trained on major residential brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For West Hollywood installs, we often recommend Daikin for ductless and heat pump systems because of their low operating noise and exacting humidity control, plus Goodman and Rheem for budget-conscious courtyard retrofits where a simple, serviceable system makes more sense than a flagship model. We keep common parts and filters in local stock so West Hollywood customers aren’t waiting on a part from a warehouse across the county when a repair is needed. That fast turnaround matters during a September heat wave.

AfterCommon AC Installation Problems We See in West Hollywood Homes
- Undersized ductwork in pre-1940 courtyard units. The original ducts were sized for gravity systems, not for newer high-efficiency blowers. When a high-static-pressure system forces air through those old runs, blower motors wear out early and rooms stay unevenly cooled.
- Rooftop condensers on mid-century flat-roof buildings. A condenser bolted directly to a roof deck transmits vibration into bedrooms below. Without isolation pads and sound blankets, the system gets noise complaints within the first week, especially with the city’s strict noise ordinance.
- All-electric retrofits that double the electrical load. Removing a gas furnace and adding a heat pump plus a backup electric strip can draw far more amps than the old panel ever handled. Skipping a proper load calculation means breakers trip on the first heat wave after the switch.
- Historic building constraints that put aesthetic limits on placement. West Hollywood’s design review rules can restrict where outdoor units sit, and many buildings don’t allow visible line sets on the facade. Concealed ducted units and careful line-set routing are often required simply to get the permit approved.
None of these problems are unsolvable. They just require planning before installation begins, not after the unit is ordered.
Pricing for AC Installation in West Hollywood, CA
Most full-system AC installations in West Hollywood land between $3,500 and $7,500. The low end covers a straightforward single-zone mini split or a small central air replacement where ductwork already exists and is in good shape. The high end reflects multi-zone ductless systems, concealed ducted air handlers, rooftop work, or a full heat pump replacement with new electrical circuits. The biggest variables are system capacity, the number of zones, and how much of the existing ductwork can be reused.

FAQs About AC Installation in West Hollywood
Yes, typically with a ductless mini split or a slim-duct system rather than full central air. Many of these buildings have original gravity furnaces in tiny basements and no chases for conventional ductwork. We route compact duct or refrigerant lines through closets that once served as elevator shafts, preserving the building’s footprint while giving each unit real cooling. Call (213) 531-5904 and we’ll walk the building with you to figure out the most honest option.
For most West Hollywood condos, a SEER2 rating of 16 to 18 hits the balance between upfront cost and operating cost. West-facing glass off streets like San Vicente or Robertson creates intense afternoon heat gain, so a variable-speed compressor in that range helps the system ramp up for the hottest hours without overshooting in the morning. Units with a SEER2 above 20 are worthwhile mainly for multi-zone homes run many hours a day. We can give you an exact recommendation after a load calculation.
We mount rooftop condensers on isolation pads, use sound blankets where the unit sits near bedroom windows, and position the condenser away from direct sight lines to neighboring courtyards. West Hollywood’s noise limits are tight, and a poorly mounted condenser will generate complaints fast. Our installs are designed to run below the noise threshold from day one. Call (213) 531-5904 and we can inspect your roof and tell you what’s achievable.
Yes, you need a load calculation for every installation, even a one-bedroom. The point isn’t size, it’s accuracy. A one-bedroom with thick 1920s walls and a shaded courtyard needs far less cooling than a top-floor unit with a west-facing wall of windows. When a contractor skips the calculation, you end up with an oversized system that short-cycles, fails to dehumidify, and drives up utility bills. We do the calculation on every job, and we show you the numbers.
Yes, in most cases a ducted heat pump can use the existing chases from the old gravity system, or we can go ductless and avoid the chases entirely. The original furnace closet often fits a slim vertical air handler, and flexible duct can follow the old register paths without opening more than a few small access points. The city’s historic review process is easier when the exterior stays untouched, which is exactly what a ductless or slim-duct approach allows.
