Short answer: A 15-year-old AC system with a 10 SEER rating costs a typical Las Vegas homeowner $1,800 to $2,400 more per year than a modern 16 SEER system — combining excess energy costs, rising repair bills, comfort penalties, and accelerated wear. Over five years, that is $9,000 to $12,000 in avoidable spending, which is more than most new systems cost to install after rebates and tax credits. If your AC is 12 years or older and you are heading into another Las Vegas summer, call (702) 567-0707 for a free cost-of-ownership assessment — we will show you exactly what your old system costs versus what a replacement would cost, with no obligation.
Key Takeaways
- A 15-year-old 10 SEER AC costs $1,000-$1,400 more per year in energy alone than a modern 16 SEER system running the same number of hours in a Las Vegas home. NV Energy's tiered rate structure amplifies this gap — old systems push you into the highest rate tiers faster.
- Repair costs accelerate after year 12. A system in years 11-15 has a 35% chance of needing a repair each year at an average cost of $500. By years 16-20, that jumps to 55% probability and $750 average cost. The cumulative five-year repair bill for an aging system runs $2,500-$5,500.
- The "comfort penalty" adds 12-16% to your energy bill. When an old single-stage system cannot hold temperature in 115-degree heat, you set the thermostat 3-4 degrees lower to compensate — each degree below 76°F costs roughly 3-4% more energy.
- Over five years, keeping a 15-year-old system costs $23,000-$32,000. Replacing it with a 16 SEER system costs $18,000-$24,000 including the purchase price. The new system is cheaper — and you get reliable cooling, a full warranty, and better air quality.
- Emergency summer replacement costs $500-$1,500 more than a planned spring installation. Equipment availability drops, scheduling is rush-only, and every contractor in the valley is booked solid.
- NV Energy rebates ($300-$2,000) reduce the net cost of a qualifying new system — money that disappears if you wait for an emergency replacement with no time to research incentives. (Note: the federal Section 25C tax credit was terminated for 2026 installations.)
The Monthly Bill You See vs. The Costs You Don't
Most homeowners judge their AC by one metric: the NV Energy bill. It shows up every month. You wince in August, feel relief in November, and move on. But that bill only captures one of five cost layers an aging AC system generates. Here is the full picture:| Cost Category | What Most People Track | What It Actually Costs (Old System vs. New) |
|---|---|---|
| Energy (electricity) | NV Energy bill | $1,000-$1,400/year excess |
| Repairs | Only when the system breaks | $300-$1,200/year average after year 12 |
| Comfort penalty | Rarely tracked | $200-$400/year in extra energy from overcompensation |
| Health and air quality | Never tracked | Poor filtration, higher allergen exposure, humidity issues |
| Property value | Only at sale | $3,000-$8,000 resale impact from HVAC age |
Energy Cost — The Biggest Line Item
Las Vegas cooling costs rank among the highest in the nation. Our AC systems run six to eight months per year — typically late March through early November. A system in Phoenix or Tucson sees similar temperatures, but few other U.S. metros combine our sustained heat with our electricity rate structure the way Las Vegas does. The core variable is your system's SEER rating — Seasonal Energy Efficiency Ratio. It tells you how many BTUs of cooling your system delivers per watt of electricity consumed. A higher SEER number means lower electricity costs for the same amount of cooling. Here is what the numbers look like for a typical 4-ton system running 2,500 hours per year in Las Vegas at NV Energy's current residential rate structure (approximately $0.12-$0.14/kWh blended rate):Annual Cooling Cost by SEER Rating
| SEER Rating | Typical Install Era | Annual Cooling Cost (4-ton) | Monthly Cost (Jun-Sep) | Monthly Cost (Oct-May) |
|---|---|---|---|---|
| 10 SEER | 2006-2012 | $2,800-$3,200 | $420-$500 | $80-$130 |
| 13 SEER | 2013-2022 | $2,200-$2,600 | $330-$400 | $60-$100 |
| 16 SEER | 2023-present | $1,600-$2,000 | $240-$310 | $45-$75 |
| 20+ SEER | 2023-present (premium) | $1,200-$1,600 | $180-$250 | $35-$55 |
Why NV Energy's Tiered Rates Make Old Systems Even More Expensive
NV Energy uses a tiered pricing structure. The more electricity you use, the more you pay per kilowatt-hour. This is where the math gets painful for old AC systems. An inefficient 10 SEER system consumes roughly 60% more electricity than a 16 SEER system for the same cooling output. That extra consumption does not just cost you the base rate — it pushes your total household usage into NV Energy's higher rate tiers. You end up paying a premium rate for electricity your efficient neighbor does not even use. Here is what that looks like in a peak summer month:| Usage Tier | Approximate Rate (2026) | 10 SEER Household | 16 SEER Household |
|---|---|---|---|
| Tier 1 (first 1,000 kWh) | ~$0.105/kWh | Uses all of Tier 1 | Uses all of Tier 1 |
| Tier 2 (1,001-2,500 kWh) | ~$0.128/kWh | Uses all of Tier 2 | Uses most of Tier 2 |
| Tier 3 (2,501+ kWh) | ~$0.145/kWh | 500-1,000 kWh in Tier 3 | Little to none |
| Typical August bill | $380-$500 | $210-$310 |
Real-World Degradation — Your 10 SEER Is Not Really 10 SEER Anymore
That 10 SEER rating was your system's efficiency when it was new — 12, 15, maybe 18 years ago. Every year of operation degrades that number. Dirty coils, worn compressor valves, refrigerant loss through micro-leaks, degraded insulation on refrigerant lines, and clogged ductwork all compound. Industry research shows AC systems lose 5-10% of their original efficiency over the first decade even with perfect maintenance. Without regular maintenance, that number climbs to 20-30%. A 10 SEER system that has not been professionally maintained may be operating at 7-8 SEER — which means it is consuming 50-60% more electricity than it did when it was new. This is why your NV Energy bill seems to go up every year even though your habits have not changed. It is not just rate increases. Your system is slowly getting worse at its job.Repair Costs — The Death by a Thousand Cuts
Nobody budgets for AC repairs. The capacitor blows on the hottest day of the year. The fan motor starts screaming at midnight. The refrigerant leak that was "fixed" last summer is back. Each repair feels like a one-time event. But when you zoom out and look at the probability curve, a pattern emerges.Repair Probability by System Age
| System Age | Chance of Needing Repair (Per Year) | Average Repair Cost | Expected Annual Cost |
|---|---|---|---|
| Years 1-5 | ~5% | $200 | ~$10 |
| Years 6-10 | ~15% | $350 | ~$53 |
| Years 11-15 | ~35% | $500 | ~$175 |
| Years 16-20 | ~55% | $750 | ~$413 |
| Years 20+ | ~70%+ | $900+ | ~$630+ |
Common Repair Costs for Aging Las Vegas AC Systems
| Component | Repair/Replace Cost | Typical Failure Window | Notes |
|---|---|---|---|
| Capacitor | $200-$350 | 8-15 years | Most common failure. Heat accelerates degradation. |
| Contactor | $150-$300 | 10-15 years | Electrical contacts wear from repeated cycling. |
| Fan motor (condenser) | $300-$600 | 10-18 years | Desert dust and heat are brutal on bearings. |
| Fan motor (blower) | $400-$700 | 12-20 years | Indoor unit. Often requires coil removal to access. |
| Refrigerant recharge | $200-$500 (R-410A) | Any age (leak-dependent) | R-22 systems: $500-$1,200+. Supply shrinking annually. |
| Control board | $300-$600 | 12-20 years | Power surges and age degrade circuit boards. |
| Compressor | $2,000-$4,000 | 12-20 years | If this fails after year 12, replace the entire system. |
| Evaporator coil | $1,200-$2,500 | 12-20 years | Las Vegas hard water causes scale buildup and leaks. |
The Repair Trap
Here is the conversation I have with homeowners almost every week: "We just spent $600 on a repair three months ago. Now they are saying the compressor is going. We cannot throw that $600 away." That $600 is already gone. It is a sunk cost. The financial question is not "how do I protect the $600 I already spent?" The question is "what will the next 12 months cost me if I repair versus replace?" If you are spending $500 to $1,000 per year on AC repairs, you are financing an inefficient system with no warranty, no efficiency improvement, and no guarantee it will not need another repair next month. That is the repair trap — each individual fix seems reasonable, but the cumulative spending exceeds what a new system would have cost. For a structured framework on when repairs stop making financial sense, see our repair vs. replace decision guide.Comfort Cost — The Invisible Tax
This is the cost that never shows up on a bill but affects your quality of life every day from May through October. An aging single-stage AC system has one mode: full blast. It runs at 100% capacity until the thermostat is satisfied, then shuts completely off. In mild weather, this works fine. On a 115-degree Las Vegas afternoon, it creates problems.The Temperature Swing Problem
A single-stage system fighting extreme heat cycles on and off constantly. Each time it shuts off, the house immediately starts warming again. The result: temperature swings of 3-5 degrees throughout the day. Your thermostat reads 76 degrees, but that is the average. Some rooms — especially upstairs bedrooms, rooms with west-facing windows, or rooms at the end of long duct runs — may be sitting at 80-82 degrees. You know this because you feel it. You walk from the living room into the master bedroom in July and the air hits you like a wall. That is not just a comfort issue. It changes your behavior.How You Compensate — And What It Costs
When parts of the house are too warm, homeowners do the natural thing: they turn the thermostat down. If the bedroom is 82 when the thermostat says 76, you set it to 72 trying to get the bedroom to 78. Now you are overcooling the living room to undercool the bedroom. Every degree you drop the thermostat below 76 degrees costs approximately 3-4% more energy. If you are setting it 3-4 degrees lower than you would with a well-functioning system, that is 12-16% more energy consumption — an extra $200-$400 per year on top of the baseline inefficiency of the old system. Modern variable-speed and two-stage systems solve this completely. They run at partial capacity for longer periods, maintaining consistent temperature across every room without the on-off cycling that creates hot spots. The difference is not subtle. Homeowners who upgrade from a 15-year-old single-stage to a modern variable-speed system describe it as living in a different house.Humidity — Las Vegas Is Not as Dry as You Think in Summer
During monsoon season — typically late June through September — Las Vegas humidity can spike to 40-60%. An oversized or aging AC system that short-cycles does not run long enough to pull moisture from the air. You end up with a house that feels clammy even at 76 degrees, which prompts you to lower the thermostat further. A properly sized modern system runs longer at lower capacity, which means more air passes over the evaporator coil and more moisture gets removed. The result is a home that feels comfortable at 77-78 degrees instead of needing to be set at 73-74.Health and Air Quality Cost
Your AC system is not just a temperature machine. It is the primary air filtration and circulation system for your home. Every cubic foot of air your family breathes passes through it multiple times per day. When that system is aging, the air quality implications are real.Filtration Limitations of Older Systems
Most AC systems installed 12-15+ years ago were designed for standard 1-inch filters with a MERV rating of 6-8. These filters catch large dust particles but allow fine particulates, pollen, pet dander, and mold spores to pass through. In Las Vegas, where desert dust, construction particulate, and windblown allergens are a constant presence, this matters more than it does in most cities. Modern systems can accommodate MERV 11-16 filters or even whole-home air purification systems that remove 95-99% of airborne particles. Upgrading the system often means upgrading your ability to clean the air your family breathes.R-22 Refrigerant — The Ticking Clock
If your AC system was installed before 2010, there is a strong chance it uses R-22 refrigerant, which was fully phased out of production in 2020. The remaining supply is reclaimed or recycled, and prices reflect the scarcity — $75 to $150 per pound compared to $10 to $20 per pound for modern R-410A. Beyond the cost issue, R-22 systems that develop leaks release an ozone-depleting substance into the atmosphere. If environmental impact matters to your family, this is worth weighing. And from a purely practical standpoint, every year that passes makes R-22 harder and more expensive to source. A recharge that costs $600 today may cost $900 next summer.Carbon Footprint
An old 10 SEER system consumes 60% more electricity than a 16 SEER system. In Southern Nevada, where a significant portion of the electricity grid is powered by natural gas, that excess energy use translates directly to higher carbon emissions. If reducing your household's environmental impact is a priority, your AC system is one of the single largest levers you have.Property Value Impact
Las Vegas is a market where the age and condition of your AC system directly affects what a buyer will pay for your home. This is not theory — it is a documented pattern that real estate agents, home inspectors, and appraisers in this valley see every day.Why AC Matters More Here Than Anywhere
In Seattle, a buyer might glance at the HVAC system and move on. In Las Vegas, the AC system is one of the first five things a serious buyer evaluates. The reason is obvious: a bad AC system in a mild climate is an inconvenience. A bad AC system in Las Vegas is an emergency waiting to happen. Buyers know this. Their agents know this. Their inspectors definitely know this. A home inspection that flags a 15-year-old AC system triggers one of two outcomes: the buyer demands a price reduction (typically $5,000-$10,000, reflecting replacement cost plus a risk premium), or the buyer walks. In a competitive market, listing with a new HVAC system removes one of the biggest objections a buyer can raise.The Numbers
Industry data from the National Association of Realtors and HVAC trade groups consistently shows that new HVAC systems recoup 60-80% of their installation cost in added home value. On a $9,000 system, that is $5,400 to $7,200 in resale value — and in a Las Vegas market where AC condition carries outsized weight, the recovery rate likely exceeds the national average. More importantly, a new system reduces days on market. Homes with updated HVAC systems sell faster because they eliminate a negotiation point and pass inspection without a major flag. In a market where every week on the listing costs you money in mortgage payments, maintenance, and stress, that speed has real financial value.The 5-Year Comparison — Keep the Old System vs. Replace
This is where the math comes together. Let us run a complete five-year cost comparison for a realistic Las Vegas scenario.Scenario: 2,400 sq ft Home, 4-Ton System
Option A: Keep the existing 15-year-old, 10 SEER system
Option B: Replace with a new 16 SEER system ($9,500 installed, before incentives)
| Cost Category | Option A: Keep Old System (5-Year Total) | Option B: New 16 SEER System (5-Year Total) |
|---|---|---|
| Energy costs | $14,000-$16,000 | $8,000-$10,000 |
| Repairs | $2,500-$5,500 | $0-$200 (warranty covers most) |
| Comfort penalty (extra energy) | $1,000-$2,000 | $0 |
| Equipment purchase | $0 | $9,500 |
| Rebates and tax credits | $0 | -$2,500 to -$4,000 |
| Emergency replacement risk (probability-weighted) | $1,500-$3,000 | $0 |
| 5-Year Total Cost | $19,000-$26,500 | $15,000-$19,700 |
Where Is the Breakeven Point?
For most Las Vegas homeowners replacing a 10-12 SEER system with a 16 SEER system, the breakeven point — where cumulative savings equal the net purchase cost — falls between year 3 and year 4. After that, every month of operation is pure savings. If you are upgrading to a 20+ SEER variable-speed system, the upfront cost is higher but the energy savings are larger, and the breakeven typically still falls within 4-5 years. After year 5, you are saving $1,500-$2,000 per year compared to the old system. Our 2026 replacement cost guide breaks down pricing by system size, brand, and efficiency tier.What About Financing?
Many homeowners hesitate on replacement because they do not want to spend $7,000-$12,000 upfront. That is completely reasonable. But look at it through a monthly lens. A $9,500 system financed at 7.9% APR over 10 years costs approximately $115 per month. The energy savings from upgrading a 10 SEER to a 16 SEER system on a 4-ton unit are $83-$117 per month. In many cases, the monthly financing payment is roughly equal to — or less than — the monthly energy savings. You are paying for a new AC with money you were already spending on electricity for the old one. Zero-percent promotional financing, when available, makes the math even more compelling. And some utility and manufacturer programs offer reduced-rate financing specifically for high-efficiency equipment.When "One More Summer" Becomes the Most Expensive Decision
I hear this every spring: "The system is still running. We will replace it after this summer." It is a completely understandable impulse. Nobody wants to spend money on something that is technically still working. But "after this summer" often becomes the most expensive three words in a Las Vegas homeowner's vocabulary.What Happens When It Fails in July
An emergency AC failure in peak summer triggers a cascade of costs that a planned replacement avoids entirely:Emergency pricing. When your AC dies on a 115-degree day, you are not shopping. You are desperate. Some contractors charge emergency premiums of 15-25% above standard pricing. You do not have the luxury of collecting three quotes and comparing them over a week. You need cold air today.
Limited equipment availability. Every HVAC distributor in Las Vegas carries less inventory in peak summer because demand has already depleted stock. Your contractor may not have the exact system that is the best fit for your home. You end up with whatever is available — which may be oversized, a different brand than optimal, or a model that costs more than what you would have chosen with planning time.
Rush installation quality. A contractor installing your system during a heat emergency is under pressure from dozens of other customers waiting. A planned spring installation gets four to six hours of unhurried attention — proper load calculation, careful brazing, correct refrigerant charge, thorough ductwork inspection, and detailed commissioning. An emergency install gets done as fast as possible so the crew can reach the next emergency. The quality difference affects how the system performs for its entire 15-20 year lifespan.
The cost gap is real. We track this internally. A planned off-season replacement saves $500-$1,500 on average compared to an emergency summer replacement for the same equipment. Our guide to the best time to buy a new AC covers seasonal pricing patterns in detail.
The Temporary Cooling Cost
When your AC fails and you are waiting 24-72 hours for a replacement, what do you do? Portable AC units ($300-$500 each, and you need at least two), hotel stays ($150-$250/night for a family), eating every meal out because the kitchen is unbearable, lost work productivity from heat stress. These emergency costs add up fast and never get counted in the "keep the old system" calculation. I have had customers tell me they spent $800-$1,200 on hotels, portable units, and restaurants during a three-day wait for their emergency replacement. That is money they would never have spent on a planned replacement in April.The Peace of Mind Factor
What is it worth to walk into summer knowing — truly knowing — that your AC will not fail? That the system has a 10-year parts warranty and a manufacturer's guarantee? That your energy bills will be predictable instead of climbing every year? That you will never open a text from your spouse saying "the AC is blowing warm air and it's 114 outside"? I cannot put a dollar figure on peace of mind. But every homeowner who has lived through an emergency failure in a Las Vegas summer knows exactly what I am talking about. The anxiety of entering June with a 17-year-old system is a cost that does not show up in any spreadsheet but is absolutely real.Making the Smart Move — Your Options
I am not here to sell you an AC system. I am here to show you the math and let it speak for itself. But you deserve to know your options, so here they are — honestly:Option 1: Professional Assessment and Tune-Up
If your system is under 12 years old and has not needed major repairs, a professional maintenance tune-up may be exactly what you need. A thorough tune-up restores some lost efficiency, catches failing components before they break, and extends your system's usable life. Think of it as buying time with data — after the tune-up, your technician can tell you honestly how much life is left and what to watch for. This is the right move for systems that still have good years ahead. A $150-$200 tune-up that prevents a $600 midsummer repair and restores 5-10% efficiency is an excellent return on investment.Option 2: Strategic Replacement Before Summer
If your system is 15 years or older, uses R-22 refrigerant, has needed two or more repairs in the past 18 months, or consistently fails to keep your home comfortable in peak heat — the financial case for replacement is strong. The optimal window for Las Vegas replacement is March through May. Contractors have open schedules, equipment is fully stocked, and there is time for a proper load calculation and unhurried installation. You also have time to research and claim every available rebate and tax credit before they are drawn down. For a full breakdown of what a new system costs in 2026, what rebates are currently available, and how to compare quotes, see our 2026 AC replacement cost guide.Option 3: The Comfort Club — Maximize What You Have
If replacement is not in the budget right now, our Comfort Club maintenance plan is designed to get the most remaining life out of your current system. It includes two tune-ups per year (spring and fall), priority scheduling if something does break, and discounts on repairs and parts. The maintenance plan does not change the fundamental math — an old, inefficient system will still cost more to run than a new one. But it reduces the probability of catastrophic failure, catches problems early when they are cheaper to fix, and gives you a professional relationship with a company that knows your system's history when the time to replace does come.Option 4: Get a Free Cost-of-Ownership Assessment

How much does it cost to run an old AC all summer in Las Vegas?
A 15-year-old 10 SEER system cooling a typical 2,000-2,800 square foot Las Vegas home costs $2,800-$3,200 per year in electricity — with $1,800-$2,200 of that concentrated in the June through September peak cooling months. When you add the comfort penalty from overcooling to compensate for hot spots, the real energy cost is closer to $3,000-$3,600. By comparison, a modern 16 SEER system running in the same home costs $1,600-$2,000 per year. The difference — $1,200-$1,600 annually in energy alone — is enough to cover the monthly payment on a financed replacement system.
At what age should I replace my AC in Las Vegas?
The national average AC lifespan is 15-20 years, but Las Vegas systems see significantly harder use. Our systems run 2,500-3,500 hours per year compared to 1,000-1,500 hours in moderate climates, plus they endure extreme heat differentials, desert dust, and hard water. In Las Vegas, plan for 10-15 years of useful life with regular maintenance. If your system is 12 years or older and showing signs of declining performance — rising energy bills, more frequent repairs, rooms that will not stay cool — it is time for a serious financial analysis. By age 15 in Las Vegas, the cost of continuing to operate almost always exceeds the cost of replacement. To learn more about how our extreme heat accelerates AC wear and tear, read our guide on how heat destroys air conditioners in Las Vegas.
Is it cheaper to repair or replace a 15-year-old AC?
In almost every scenario for a 15-year-old system in Las Vegas, replacement is cheaper when you account for the full picture. A single repair may only cost $400-$800, but you also need to factor in the ongoing energy penalty ($1,000-$1,400 per year above a modern system), the rising probability of additional repairs (35-55% chance each year at this age), and the risk of catastrophic failure requiring emergency replacement at premium pricing. Over a five-year horizon, keeping a 15-year-old system typically costs $19,000-$26,500 while replacing it costs $15,000-$19,700 including the purchase price. Our repair vs. replace guide provides a step-by-step framework for making this decision.
How much can I save with a new high-efficiency AC system?
The savings depend on what you are replacing and what you are installing. Upgrading from a 10 SEER to a 16 SEER system on a 4-ton unit saves $1,000-$1,400 per year in energy costs alone. Upgrading to a 20+ SEER variable-speed system saves $1,400-$1,800 per year. Add in avoided repairs ($300-$750 per year for aging systems), the eliminated comfort penalty ($200-$400 per year), and reduced health-related costs from better air quality, and the total annual savings range from $1,800 to $2,800. Over the 15-20 year lifespan of the new system, that is $27,000-$56,000 in cumulative savings — many times the cost of the system itself. For a detailed look at how different AC technologies compare, see our system comparison guide.
Do new AC systems qualify for rebates or tax credits in 2026?
The federal Section 25C tax credit was terminated for equipment installed after December 31, 2025, under the One Big Beautiful Bill Act (signed July 2025). However, NV Energy's PowerShift rebate program remains fully available and offers $300-$2,000 for qualifying high-efficiency systems depending on efficiency tier. Some manufacturers also run promotional rebates that can stack with the NV Energy incentive. Combined, these rebates can reduce the net cost of a new system by $500-$2,500. The key is to research and secure these incentives before you buy — during an emergency replacement, there is rarely time to optimize your rebate strategy.
How long does a new AC system take to pay for itself?
In Las Vegas, faster than almost anywhere else in the country. The payback period depends on three variables: the net cost of the new system (after rebates and tax credits), the energy savings per year, and the avoided repair costs. For a typical scenario — replacing a 10 SEER system with a 16 SEER system at a net cost of $6,000-$8,000 after incentives, with annual energy savings of $1,000-$1,400 and avoided repairs of $300-$500 — the breakeven point falls between year 3 and year 4. After that, every month of operation represents pure savings. For higher-efficiency systems (20+ SEER), the upfront cost is higher but the annual savings are larger, and breakeven typically occurs within 4-5 years. The high number of annual cooling hours in Las Vegas (2,500-3,500) is what makes payback so much faster here than in milder climates where systems run 1,000-1,500 hours.
What is the most expensive month to replace an AC in Las Vegas?
July, without question. July combines peak demand for HVAC contractors, depleted equipment inventory at distributors, and maximum desperation from homeowners whose systems just failed. Emergency replacement in July typically costs $500-$1,500 more than the same installation performed in March, April, or May. Beyond the direct price premium, July replacements often mean accepting whatever equipment is available rather than choosing the optimal system for your home, and rushed installations under extreme time pressure. The most cost-effective replacement window in Las Vegas is March through May — contractors have open schedules, full inventory is available, and there is time for proper load calculations and unhurried installation. Even September and October offer better pricing than peak summer. Read our full analysis in the best time to buy a new AC in Las Vegas.
The Bottom Line
I started this article with a promise to show you the real math. Here it is, one more time: A 15-year-old 10 SEER AC system in Las Vegas costs $1,800-$2,400 more per year than a modern 16 SEER system. Over five years, that is $9,000-$12,000 in avoidable costs — money that could pay for a new system, a family vacation, a kitchen remodel, or simply stay in your savings account where it belongs. The old system is not saving you money by continuing to run. It is costing you money every hour it operates. The numbers are not ambiguous. If you are heading into another Las Vegas summer with an aging system, you have two choices: spend $3,800-$5,300 this year operating and repairing the old system, or invest in a replacement that costs less to own over the next five years and delivers better cooling, cleaner air, and complete peace of mind. As a CFO, the decision is straightforward. As a Las Vegas homeowner, the relief is immediate.Call The Cooling Company at (702) 567-0707 for a free cost-of-ownership assessment, or book online to schedule at a time that works for you. We will show you exactly what your old system costs versus what a new one would cost — your numbers, your home, no pressure.
