A new AC system in North Las Vegas typically runs $3,500 – $7,500 installed, and the job usually takes one full day. That includes removing the old unit, setting the new one, connecting ductwork, charging refrigerant, and testing airflow before we leave. If you’re replacing a builder-grade system in Aliante or Eldorado that never quite kept up, we’ll get it right this time. Call (725) 726-3813 for a written quote before any work starts.
We know North Las Vegas because we work here constantly. From the newer subdivisions off Aliante Parkway to the older streets near Nellis Air Force Base and downtown, the homes, the heat, and the equipment all have their own character. A 112°F day doesn’t leave room for guesswork. We size every install with a real load calculation, not a rule of thumb, and we put the price in writing before a single tool comes out of the truck.
Why Cold Harbour Heating and Air Las Vegas Is North Las Vegas’s Preferred AC Installation Company
The work we do in North Las Vegas has to stand up to one of the harshest cooling climates in the country. Summer afternoons regularly push past 105°F, and those are the days a marginal install shows its cracks. We’ve pulled enough failed builder-grade units out of mid-2000s homes to know exactly where the shortcuts were taken, and how to correct them so the replacement actually delivers what it should.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands, including Carrier, Trane, Lennox, and American Standard. That means the person at your door can service whatever system is already there and install whichever brand fits your home’s load, budget, and ductwork. We don’t push one brand; we install the right one for the job.
Victor Mancini leads our team with a simple expectation: say the price before the work, show up in the window given, leave the property cleaner than found, put the guarantee in writing, and come back if something fails. That’s the Kingswell Way, and it’s been our operating standard since 2003 as an independently owned and operated member of the Kingswell network.
Homeowners in North Las Vegas have been let down before. A no-show technician, a price that jumped at the door, a brand-new system that quit in July. We hear it every week. So we put it on paper: a written price before any work begins, a firm arrival window, and every repair and install backed by our 365-Day Done Right Promise. If a repair we make fails within a year, we return and correct it at no charge. Written down. Not verbal.
Styles & brands we work with







AC Replacement in North Las Vegas
AC Replacement in North Las Vegas is a different job than in most markets, because so much of the equipment we pull out was chosen for speed rather than fit. The first sentence of many of these jobs is the same: the system was installed too small, too cheap, or too fast during the building boom, and it limped along until the first serious heat wave exposed it. A proper replacement here means running a full Manual J load calculation, checking static pressure, inspecting duct transitions, and then selecting a system that matches the actual house, not the house the builder imagined.
Replacement cost in North Las Vegas follows the same $3,500 – $7,500 range as new installation, because the job is nearly identical: remove old equipment, address any ductwork problems, set the new unit, charge it correctly, and verify airflow room by room. The biggest cost drivers are system tonnage, brand, whether you’re replacing a rooftop package unit or a split system, and any duct corrections needed to fix airflow problems in the original install.
Correcting the Builder’s Shortcuts
The mid-2000s boom in Aliante and Eldorado produced thousands of homes with builder-grade heat pumps sized by rule of thumb. Many of those systems were missing filter dryers, had kinked line sets behind the condenser, and carried undersized tonnage that simply couldn’t hold setpoint above 105°F. When we replace those systems, we address the original install errors too. A new unit on top of a kinked line set is still a compromised system.
When Replacement Beats Repair
If your system is 12 to 15 years old, uses R-22 refrigerant, and needs a major compressor or evaporator coil repair, replacement usually makes more sense. In North Las Vegas’s climate, that’s not a stretch, it’s the reality of 100+ days above 100°F every year. We’ll show you the numbers for repair versus replacement so you can decide with the full picture.
Central Air Conditioning Installation in North Las Vegas
Central Air Conditioning Installation in North Las Vegas starts with the house, not the equipment. Before we quote a system, we look at square footage, ceiling height, window orientation, insulation levels, and the condition of the existing ductwork. A home near downtown built in 1985 has different needs than a 2010 Aliante two-story, even if they’re the same square footage. That’s why every install begins with a load calculation, not a phone call with the office asking “what size did the last one say?”
The installed price for central AC in North Las Vegas runs $3,500 – $7,500. That covers the outdoor condenser, indoor air handler or coil, line set, pad, electrical disconnect, thermostat wiring, refrigerant charge, drain line, and labor. If your ductwork needs sealing or repair, we’ll include that as a separate line item so you’re not surprised. You get the written number before we start anything.
Replacing a Rooftop Package Unit
Older North Las Vegas homes, especially 1970s-80s tract housing near Nellis Air Force Base, often have rooftop package units that have been baking in direct sun for decades. Replacing one means crane or manual lift work, new curb adapters if needed, and careful attention to the roof penetration. We’ve done enough of them that the roof work is routine for our crew, not a reason for a change order.
Ductwork and Airflow Corrections
The old flex duct in some 1980s-90s subdivisions around downtown has degraded badly in the dry Mojave air. Crushed runs, disconnected boots, and undersized returns starve even a new system. When we install central AC, we measure static pressure and test airflow in every room. If the ductwork can’t carry what the new system produces, we tell you before we sell you a bigger unit. That’s how you avoid paying for a 4-ton system that only delivers 3 tons of cooling.
Trusted Brands We Service in North Las Vegas
Our technicians are factory-trained on Carrier, Trane, Lennox, and American Standard equipment, among others, so the brand discussion comes down to what fits your home and budget, not what’s on the truck. Carrier brings solid heat pump performance in high desert heat. Lennox offers high SEER2 ratings for efficiency-minded homeowners. Trane’s build quality appeals to people planning to stay in the house for decades. We keep common parts for these brands stocked locally for our North Las Vegas customers, which shortens turnaround when a board or a capacitor fails during the season.
Common AC Installation Problems We See in North Las Vegas Homes
- Missing filter dryers on builder-grade installs. A filter dryer is a small, cheap component that removes moisture and debris from the refrigerant line. Builders skipped them on hundreds of mid-2000s Aliante and Eldorado homes, and the compressors failed years early as a result. If we’re installing a new system, we always verify one is in place or add it.
- Kinked line sets starve the compressor. The line set carries refrigerant between the indoor coil and the outdoor condenser. A kink restricts flow, which makes the compressor run hot and shortens its life. We’ve found kinked line sets in a large share of 12-to-15-year-old homes we’ve replaced equipment in.
- Undersized tonnage from rule-of-thumb sizing. Many newer North Las Vegas homes got a 3-ton system when a proper Manual J load calculation says they need 4 tons. The system runs constantly, never satisfies the thermostat, and the upstairs bakes. A new correctly-sized system is often the only fix.
- Leaking evaporator coils from old swamp cooler conversions. Some older downtown North Las Vegas homes were originally built with swamp coolers and converted to refrigerated air later. The early conversions used coils that corroded from alkaline tap water, and many are still leaking today. Replacement means a modern coil matched to the current system.

What moves the final number in North Las Vegas? System tonnage and SEER2 rating are the big two. A 3-ton 14 SEER2 unit for a 1,500-square-foot rancher costs less than a 5-ton 18 SEER2 unit for a 3,200-square-foot Aliante two-story. Ductwork corrections add cost when the original install botched the airflow. Rooftop package units often run a bit more than ground-level split systems due to roof access and lift work.

FAQs About AC Installation in North Las Vegas
My 2007 Aliante home still has the original builder heat pump. What should I check before replacing it?
The smartest move is to have a technician check static pressure, subcooling, and superheat to see what’s actually failing before you commit to a new system. But on a 15-to-18-year-old builder heat pump in Aliante, the odds are you’re dealing with a missing filter dryer, a kinked line set, or undersized tonnage, or all three, and those aren’t band-aid repairs. The quick check: if your upstairs never holds below 80°F above 105°F outside, the system was likely sized wrong from day one. We’ll run the load calculation and show you the numbers before recommending replacement. Call (725) 726-3813 and we’ll schedule it.
Why does my upstairs in North Las Vegas never cool below 80°F on hot days even with a new AC?
Because the system was either sized by rule of thumb instead of a load calculation, or the ductwork can’t deliver what the air handler produces. Most of these homes are two-story boxes with high heat gain and long duct runs to the upper floor. If the static pressure is too high or the return can’t pull enough air from upstairs, no amount of BTUs fixes it. In our experience across North Las Vegas, the fix is usually a combination of corrected tonnage and duct transitions, not a bigger unit by itself. That’s exactly what we did in the Aliante two-story last July where the original install had kinked the line set behind the condenser.
How does registering my new AC warranty in North Las Vegas protect me, and what does it not cover?
Registering your equipment with the manufacturer within 60 days of installation activates the parts warranty, usually 10 years for major components like the compressor and coils. If you don’t register, most brands drop you to a 5-year base warranty. What it does not cover is labor, refrigerant, or damage caused by poor installation practices, which is why the installer matters as much as the brand. Our installs come with our written workmanship guarantee on top of the manufacturer’s coverage. If our repair fails within 365 days, we come back and correct it at no charge.
Do I need a heat pump or a furnace plus AC in North Las Vegas?
For most North Las Vegas homes, a heat pump is the right answer. Cooling is the dominant load here, with over 100 days above 100°F per year and very mild winters. A heat pump handles both, and modern high-efficiency heat pumps hold their rated capacity better at high outdoor temperatures than the units from 15 years ago. A furnace plus AC makes sense only if you have a strong existing gas furnace that’s in good shape, or you prefer gas heat for the handful of cold nights. We’ll walk through both options and show you the numbers either way.
What is SEER2 and why does it matter for a new AC in North Las Vegas?
SEER2 is the updated efficiency rating for central cooling equipment that took effect in 2023, measuring seasonal cooling output per unit of energy consumed under more realistic testing conditions. In North Las Vegas, where your AC runs hard from May through September, the difference between a 14 SEER2 and an 18 SEER2 system shows up directly on your NV Energy bill every month. Higher SEER2 units cost more upfront but buy back their premium in a few years in this climate. We’ll show you the payback math for your home when we quote the job.
When Your AC Is Done Wrong, You Pay Twice
The whole point of this page is simple: North Las Vegas has a lot of homes with AC systems that were under-designed from the day they were installed. Builder-grade equipment, skipped filter dryers, kinked line sets, undersized tonnage. Those systems failed early or never worked right, and now the homeowner is staring at a replacement bill when the system should have lasted another decade.
We don’t want you to pay twice for a mistake someone else made. When Cold Harbour Heating and Air Las Vegas installs your system, we size it correctly, charge it properly, verify the airflow, and put the price in your hand before we begin. Then we back the work with a written 365-Day Done Right Promise.
If your North Las Vegas home still has the original builder AC, or a replacement that never cooled like you expected, call Victor Mancini and the team at (725) 726-3813. We’ll come out, run the load calculation, give you a written quote, and answer every question you have. No voicemail maze. No price that changes at the door.
