As the summer heat in Nevada intensifies, many residents are concerned about high energy bills while trying to stay cool. We understand the challenge of balancing comfort and cost during our state's extreme temperatures. That’s why energy-smart practices like proper AC maintenance and repair, shading, insulation, and thermostat control are more important than ever.
The Nevada summer brings unique challenges, with temperatures regularly exceeding 100 degrees in many areas. Strategic planning now can help you avoid discomfort and excessive costs in the coming months. Simple adjustments like planting trees on the south and west sides of your home provide natural insulation against the relentless heat.
In this article, we've gathered practical, cost-effective solutions that don’t require expensive renovations or complex installations.
From sealing your home properly to installing window coverings, these strategies work together to form a comprehensive AC energy-saving plan that keeps your home comfortable and your energy costs manageable.
How air conditioning works during Nevada’s heat
Air conditioning systems play a crucial role in Nevada homes, especially during scorching summer days when temperatures regularly exceed 100°F. These systems operate under far more intense conditions than in cooler climates, which means they must be properly sized, well-maintained, and energy efficient.
The cooling process in extreme heat
A typical home cooling system operates on a simple principle: it removes heat from inside your home and expels it outdoors. Most homes in Nevada use one of the following systems:
- Central air conditioning systems, which distribute cool air through ductwork to multiple rooms
- Ductless mini-split systems, which cool individual zones and are ideal for smaller homes or additions
- Evaporative coolers (swamp coolers), which are effective in dry climates by cooling air via water evaporation
In Nevada’s desert climate, evaporative coolers are cost-efficient during dry months but lose performance during monsoon season when humidity rises.
System sizing is another major factor. An undersized unit will run constantly without effectively cooling the space, while an oversized unit will short-cycle (turning on and off too often) leading to energy waste and system wear.
If you’re unsure whether your current system is sized appropriately, consider reviewing your setup with a professional. Explore our cooling system installation services to ensure optimal efficiency.
The role of the compressor and refrigerant
At the heart of your AC system is the compressor, which pressurizes refrigerant and drives the heat exchange process. Here’s how it works:
- Warm indoor air passes over the evaporator coil, transferring heat to the refrigerant
- The now-heated refrigerant travels to the outdoor condenser coil
- The refrigerant releases heat to the outdoor air and cools back down before circulating again
In Nevada’s summer, with outdoor temperatures often exceeding 110°F, the compressor must work significantly harder to push heat into already hot air. This strain reduces system efficiency and increases the likelihood of breakdowns if the system isn’t regularly maintained.
That’s why regular AC maintenance and repair is essential, especially before peak season. Dirty coils, worn parts, or low refrigerant levels can drastically reduce your system’s performance and drive up energy usage.
Energy demand during heat waves
Nevada heat waves create massive pressure on both your cooling system and the power grid. During peak summer afternoons, electricity usage can double compared to cooler months. Thousands of air conditioning systems running simultaneously increase the risk of power surges, brownouts, and rising utility costs.
Smart energy strategies for peak demand
To reduce your cooling expenses and support grid stability, consider the following practices during heat waves:
- Set your thermostat to 78°F when at home, which offers a comfortable balance between cooling and efficiency.
- Raise your thermostat by 7–10°F when you're away for more than two hours to save energy.
- Pre-cool your home in the morning, then limit AC use during peak hours (typically 1–7 PM).
- Use ceiling fans to maintain comfort while allowing higher thermostat settings.
- Close curtains or shades during the hottest part of the day to block solar heat gain.
Each degree below 78°F can increase energy usage by 3–5%, so keeping temperatures consistent can yield noticeable savings. These habits form part of a complete AC energy-saving strategy that adapts to Nevada's most extreme summer days.
Time-of-use energy pricing
Many Nevada utility companies employ time-of-use (TOU) pricing during the summer months. This means energy used during peak hours can cost significantly more. Avoid running appliances, especially your AC, during these times if possible.
Smart thermostats are excellent tools to help manage usage and automate your cooling schedule. They allow for pre-programming and remote adjustments via smartphone apps, making it easier to align your home’s cooling with lower-rate periods.
If you’re unsure whether your current system can handle the load efficiently, consider a system check-up or upgrade. See our available HVAC services for support.
Maximizing energy savings with AC
Reducing electricity usage without sacrificing comfort is possible with the right combination of system settings, home upgrades, and smart behavior. This section breaks down actionable techniques to help you implement a full AC energy-saving strategy.
Setting your programmable thermostat efficiently
A programmable or smart thermostat is one of the most effective tools for reducing cooling costs. To optimize it:
- Set it to 78°F when you're home. This is the most efficient cooling temperature recommended by energy experts.
- Raise the temperature by 7–10°F when you're away for extended periods.
- Use the “eco” or “energy-saving” mode, available in most modern thermostats, to automatically balance comfort and efficiency.
- Program temperature changes to align with utility time-of-use rates (e.g., reduce AC use during 1–7 PM).
Smart thermostats can also learn your schedule and adjust accordingly, giving you full control over your AC energy-saving plan—even when you're not home.
Improving insulation for better cooling
One of the least visible but most powerful upgrades for cooling efficiency is attic insulation. Nevada homes benefit greatly from upgraded insulation because of the extreme outdoor heat.
- Aim for R-38 to R-60 insulation in attic spaces.
- If you can see your ceiling joists, you likely need more insulation.
- Consider installing radiant barriers, which reflect heat rather than absorbing it.
- Ensure attic ventilation is adequate, stagnant hot air buildup negates the benefits of insulation.
Adding proper insulation can reduce cooling costs by up to 15% and dramatically improve comfort during heat waves. These changes are foundational to your home’s AC energy-saving infrastructure.
Leveraging shade trees and window coverings
Strategic use of exterior and interior shading is one of the most cost-effective AC energy-saving techniques available to Nevada homeowners. With temperatures often soaring past 100°F, any reduction in solar heat gain has a significant impact on both comfort and energy bills.
Natural shading with trees
Planting deciduous trees, particularly on the south and west-facing sides of your home, can block direct sunlight during the hottest parts of the day. These trees lose their leaves in winter, allowing sunlight to warm your home during cooler months.
- According to the U.S. Department of Energy, well-placed trees can reduce a household’s cooling costs by up to 30%.
- Medium-sized shade trees begin providing noticeable cooling within 5–10 years of planting.
- A tree planted just 20 feet from a window can reduce solar exposure by up to 70%.
When combined with proper AC maintenance/repair and system efficiency improvements, these natural cooling tactics become even more powerful. Learn more about maintaining your system for optimal performance here.
Interior window treatments that reduce heat gain
While trees offer long-term benefits, window coverings deliver immediate impact:
- Close blinds and curtains during peak sun hours (11 AM to 5 PM) to cut indoor heat gain by up to 45%, especially on south- and west-facing windows.
- Use cellular (honeycomb) shades, which trap air in pockets that create insulation against heat.
- Light-colored window treatments reflect rather than absorb sunlight, helping to maintain cooler room temperatures.
- Add thermal curtains or blackout panels to block UV rays and maintain indoor climate control.
By combining natural shade with interior and exterior window coverings, you’re not only reducing solar heat gain but also relieving stress on your AC unit. This contributes to better system longevity and deeper AC energy-saving gains across the summer season.
Comparing window air conditioners and central AC
When it comes to cooling your Nevada home efficiently, the right type of air conditioning system can make a significant difference, not just in comfort, but in your monthly bills. Choosing between window AC units and central AC systems depends on your home’s size, layout, usage habits, and long-term goals for energy efficiency.
A Window AC is best for focused, short-term cooling:
- Ideal for small homes or single-room use
- Consume between 500 to 1,500 watts, making them more energy-efficient when cooling only one space
- Less expensive to purchase and install
If you only use specific rooms during the day, window units can cut cooling costs by 30–50% compared to a central system cooling the entire home. However, they typically lack advanced filtering or humidity control features.
On the other hand, a central AC is better for full-home comfort and long-term savings:
- Suitable for larger homes with consistent cooling needs
- Use 3,000 to 5,000 watts, but can be more efficient when properly zoned and maintained
- Provide whole-home temperature consistency and better air quality control
Modern central AC systems with SEER (Seasonal Energy Efficiency Ratio) ratings of 16 or higher offer significant AC energy-saving advantages over older units with ratings of 10 or less.

Supplemental cooling strategies for hot days
When Nevada’s desert heat peaks, your AC system doesn’t have to work alone. Supplemental cooling techniques can significantly reduce system strain, lower energy usage, and improve comfort without major investments.
Using ceiling fans the smart way
Ceiling fans use minimal electricity (usually 15 to 90 watts) and enhance your cooling strategy by creating a wind-chill effect.
- In summer, set fans to spin counterclockwise, which pushes cool air down
- With proper use, you can raise the thermostat by 4°F and feel just as cool
- Turn fans off when you leave a room—fans cool people, not spaces
Tip: Make sure your fan is the right size for the room. A 42–48 inch fan is ideal for rooms up to 225 square feet.
Ventilation strategies that actually work
Natural ventilation is powerful, especially during early mornings or evenings when outdoor air is cooler than indoor temperatures.
- Create cross-ventilation by opening windows on opposite sides of the house
- Use exhaust fans in kitchens and bathrooms to remove hot, humid air
- Install a whole-house fan, which pulls cool air in through windows and pushes warm air out through attic vents, best used when temps drop in the evening
Supplementing your AC system this way helps you get more from your AC energy-saving efforts and reduces wear on critical components. If your system is struggling to keep up despite these techniques, it may need inspection. Schedule a maintenance check to keep things running smoothly.
Health and safety precautions in extreme heat
While AC energy-saving is essential for managing costs and sustainability, safeguarding your health during heatwaves is even more critical. Nevada’s summer temperatures can be dangerous, especially for children, seniors, and those with underlying health conditions.
Avoiding dehydration and heat exhaustion
Staying hydrated and cool is your first line of defense against heat-related illnesses. Follow these recommendations during peak heat events:
- Drink 8–10 glasses of water daily, even if you don’t feel thirsty
- Avoid alcohol and caffeine, they dehydrate the body
- Eat smaller, lighter meals that don’t overheat your metabolism
- Use cooling towels on your neck or wrists for fast relief
- Schedule outdoor activities for early morning or evening hours
Wearing loose-fitting, light-colored clothing helps your body regulate temperature naturally. Indoors, ceiling fans and natural ventilation can help support your AC system without adding energy load.
Recognizing signs of heat stroke
Heat stroke is a medical emergency. If someone shows the following signs, act immediately and call 911:
- Body temperature above 103°F
- Hot, red, dry or damp skin
- Rapid pulse, dizziness, nausea
- Confusion, loss of consciousness
While waiting for emergency services, move the person to a shaded or air-conditioned space, apply cold compresses or cool towels, and avoid giving them ice-cold water too quickly.
And remember: Never leave people or pets in parked cars. Even with windows cracked, cabin temperatures can become deadly in minutes.
