AC installation in Las Vegas is not a job to gamble on. A correctly sized, properly installed system is the difference between a house that holds 74 degrees in July without breaking a sweat and one that runs nonstop from May through September, delivers lukewarm air, and still hands you a $600 power bill. Cold Harbour Heating and Air Las Vegas has been putting in residential cooling systems across the valley since 2003, and every install comes with a written price before the first tool comes out of the truck. Victor Mancini and our install crews work in Summerlin, Centennial Hills, Southern Highlands, Winchester, and every neighborhood in between. If your AC is dying or dead, call (725) 726-3813 and a live person answers, day or night.

Styles & brands we work with
Furnace Installation
Furnace Installation is the process of replacing or newly installing the gas or electric heating unit that pushes warm air through your home’s ductwork during Las Vegas winter nights. You need it when your existing furnace is over 15 years old, when the heat exchanger has cracked, or when repair costs would exceed half the price of a new unit. Cold Harbour Heating and Air Las Vegas installs furnaces sized to your home’s square footage and duct layout, not to a rule-of-thumb guess. In Las Vegas, a furnace installation typically runs $3,500 – $7,500 depending on the efficiency tier and whether the existing ductwork can be reused. Every quote includes the written price up front and the 365-Day Done Right Promise in writing before we leave.
The Las Vegas Winter Reality
Desert winters drop into the 30s at night, and a failed furnace in a slab-on-grade home in Sunrise Manor or Whitney gets uncomfortable fast. We size furnaces for the cold snaps, not just the mild afternoons, so the system cycles correctly without short-cycling.
Written Price, Firm Window
Victor Mancini’s crews arrive in the window we gave you on the phone. The price we hand you before the job starts is the price on the invoice. That is The Kingswell Way, and it applies to every furnace installation we do in Las Vegas.
HVAC Installation
HVAC Installation covers the full heating and cooling system: the outdoor condenser, the indoor air handler or furnace, the evaporator coil, and the controls that tie them together. You need it when both halves of your system are at the end of their life, or when a new build in Las Vegas needs a complete comfort package from scratch. Cold Harbour Heating and Air Las Vegas installs complete HVAC systems as matched pairs so the efficiency rating on the label is the efficiency you actually get. A full HVAC installation in Las Vegas generally costs $3,500 – $7,500, with the final number driven by system tonnage, SEER rating, and whether new line sets or duct modifications are required. We hand you the written price before any work begins.
Matched Systems, Real Efficiency
A high-efficiency condenser paired with an old, mismatched coil will never hit its rated performance. We install matched systems and verify refrigerant charge and airflow before we call the job done.
When to Replace Both at Once
If your furnace is from the early 2000s and your AC condenser is just as old, replacing both at once usually costs less than doing them two years apart. One install date, one written guarantee, one team on the roof and in the closet.
Heat Pump Installation
Heat Pump Installation means putting in a single outdoor unit that both cools your home in summer and heats it in winter by moving heat rather than burning fuel. It is a strong fit for Las Vegas homes because our cooling season is long and our heating demand is modest, which is exactly the climate where a heat pump earns its keep. Cold Harbour Heating and Air Las Vegas installs heat pumps from Lennox, Goodman, Rheem, and York, sized to your home’s actual heat gain and heat loss. A heat pump installation in Las Vegas typically runs $3,500 – $7,500, with the spread driven by capacity, cold-climate performance, and whether you are replacing an existing furnace or adding a heat pump as the primary system. The written price comes before the work, every time.
Why Las Vegas Homes Suit Heat Pumps
With cooling loads dominating the year in communities like Aliante and Spring Valley, a heat pump gives you one system to maintain instead of two, and it moves three to four times more heat energy than it consumes in electricity.
Dual-Fuel and Full Electric Options
Some Las Vegas homeowners keep a gas furnace for the coldest nights and add a heat pump for the rest of the year. We will walk you through both options and put the numbers in writing so you can decide on facts, not a sales pitch.
Ductless Mini Split Installation
Ductless Mini Split Installation puts a small outdoor unit outside and one or more slim indoor wall, floor, or ceiling units inside, connected only by a small refrigerant line instead of ducts. You need it when a Las Vegas home has an addition, a garage conversion, a sunroom, or a room that never quite cools because the existing ductwork does not reach it properly. Cold Harbour Heating and Air Las Vegas installs ductless systems in homes across Paradise, AC Installation - North Las Vegas, and Summerlin, with each indoor zone controlled independently. A ductless mini split installation in Las Vegas generally lands between $3,500 and $7,500 depending on the number of indoor heads and total capacity. We give you a written line-item price before the first bracket goes on the wall.
Zoned Comfort Without Ducts
Each indoor head runs on its own thermostat, so a home office in Centennial Hills can hold 72 degrees while the rest of the house idles at 78. That is real savings, not a brochure claim.
Clean Install, Minimal Disruption
The refrigerant line runs through a small opening, usually hidden behind the indoor unit and along the exterior wall. Our crews leave the site cleaner than they found it, which is part of the written promise we make on every job.
AC Replacement
AC Replacement means removing your old outdoor condenser and indoor coil, and installing a new, properly matched cooling system in its place. You need it when your current AC is over 12 years old, uses R-22 refrigerant, or has needed multiple repairs in the last two seasons. Cold Harbour Heating and Air Las Vegas replaces AC systems across Las Vegas with units sized by a full load calculation, not by reading the old unit’s data plate and hoping it was right. An AC replacement in Las Vegas typically costs $3,500 – $7,500, driven by tonnage, SEER rating, and whether the existing lines and electrical disconnect can be reused. The written price is in your hand before the old unit comes off the pad.
Old Systems and R-22 Refrigerant
If your system still runs on R-22, the refrigerant alone now costs more per pound than many repairs are worth. Replacing with a modern R-410A or R-454B system stops that cost forever.
Replacement Done Right the First Time
A replacement is only as good as the install: the evacuation, the charge, the airflow settings, the drain line pitch. Our crews are trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so the new system performs the way the factory intended.
Central Air Conditioning Installation
Central Air Conditioning Installation is the installation of a complete ducted cooling system: outdoor unit, indoor evaporator coil, and the blower that moves conditioned air through your home’s existing ductwork. You need it for a new build, a major remodel, or when your current central system has reached the end of its service life. Cold Harbour Heating and Air Las Vegas installs central air conditioning throughout Las Vegas, including Whitney, Sunrise Manor, and AC Installation in Nellis AFB, and every installation starts with a written price and a firm arrival window. A central air conditioning installation in Las Vegas typically runs $3,500 – $7,500 depending on capacity, efficiency, and any duct sealing or minor modifications the system needs to perform correctly. We put the 365-Day Done Right Promise in writing on every job.
Ductwork Matters as Much as the Unit
A brand new AC attached to leaky, undersized ducts in a 1980s home in Winchester will cool poorly and cost a fortune to run. We check the ducts and tell you honestly what the system actually needs.
The Kingswell Guarantee on Every Install
The Kingswell Way means the price is on paper before the work starts, the crew shows up in the window you were given, the job site is left clean, and the guarantee comes home with you in writing. That is how Cold Harbour Heating and Air Las Vegas has operated since 2003.
Brands We Service
Our technicians carry factory training and service experience on Lennox systems, and we stock common OEM parts for the Lennox units found throughout Las Vegas neighborhoods like Summerlin and Southern Highlands. We know the quirky control boards and the coil designs particular to that line, and we install them right the first time.
Goodman units are common in Las Vegas for their straightforward design and reasonable parts pricing, and our crews have replaced and installed dozens of them across Aliante and Spring Valley. Rheem and York systems also come through our shop regularly, and whether you have a Rheem heat pump in Winchester or a York condenser in Centennial Hills, we can service it, size a replacement, or install a new one. Whatever make you have, we can help.

- Warm air blowing from the vents. If the system runs and the air coming out is not noticeably cooler than room air, the refrigerant charge is low, the compressor is failing, or the coil is frozen. In Las Vegas heat, this gets worse by the hour.
- Short cycling, on and off every few minutes. A system that kicks on and shuts off rapidly is tripping a safety or struggling against a failing component. It wastes power and will eventually leave you with no cooling at all.
- Ice on the refrigerant lines or the indoor coil. Ice means airflow is blocked or refrigerant is low, and running the system while frozen can destroy the compressor. Turn the system off and call us before it becomes a full replacement.
- Strange sounds from the outdoor unit. Grinding, squealing, or banging from the condenser points to failing bearings, a dying fan motor, or a compressor on its way out. A quick repair trip costs far less than ignoring it.
- Your power bill spiked with no obvious cause. A cooling system that has lost efficiency will run longer and work harder to hit the same temperature. When the July bill jumps 40% and your habits have not changed, the AC is usually the culprit.
Our Process, Step by Step
- 1
Call and talk to a person. You call (725) 726-3813 and a live person answers, any hour, any day. We take your address, note what the system is doing, and give you a firm arrival window on that call.
- 2
Arrival in the window we promised. A background-checked, uniformed technician arrives in the window you were given. We introduce ourselves, put on shoe covers inside your home, and listen while you describe what you have been seeing and hearing.
- 3
Full system inspection and load review. We measure the home, check the ductwork, inspect the electrical service, and assess the existing equipment. If this is a replacement, we run a load calculation based on square footage, window exposure, insulation, and the orientation of your home, not a rule of thumb.
- 4
Written price, no surprises. We hand you a written line-item price before any work begins. The equipment, the labor, the parts, the disposal of the old unit, everything. If the scope changes during the job, we stop and put the new number in writing too.
- 5
Install, test, and clean up. Our crew installs the system, verifies refrigerant charge and airflow, tests the thermostat, and then cleans the work area until it looks like we were never there. Before we leave, you get your written 365-Day Done Right Promise. When a repair is involved, that guarantee means if it fails inside a year, we come back and fix it at no charge.
How Much Does AC Installation Cost in Las Vegas?
A typical AC Installation pricing in Las Vegas runs $3,500 – $7,500 depending on the size of the home, the efficiency of the system, and the condition of the ductwork. A basic 3-ton system in a modest single-story home in Sunrise Manor or Whitney will sit at the lower end, while a high-efficiency two-stage unit with variable-speed air handling for a larger two-story in Summerlin or Southern Highlands will land toward the top of the range. What drives the price is tonnage (the cooling capacity sized to the home’s heat gain), SEER rating (higher efficiency costs more up front and less to operate), and any duct or electrical work required to bring the system up to code. To avoid overpaying, always insist on a written line-item quote before the work starts, and ask whether the contractor has sized the system with a load calculation or just matched the old unit’s capacity. Our free estimates include the full inspection, the load calculation, and a written fixed price that does not change at the door.
