Deciding to get a generator is easy; figuring out which one to buy can feel overwhelming. You’re faced with choices between standby and portable models, various fuel types, and a dozen different brands, all with their own technical specs. It’s enough to make anyone’s head spin. Our goal is to cut through that confusion and give you a clear, straightforward path to making a confident decision. We’ll break down the essential factors, like sizing, cost, and key features, so you can find the perfect generator for your house that fits your family’s needs and budget without all the stress.
Key Takeaways
- Decide on your priority, convenience or cost: Standby generators provide seamless, automatic power for your whole home, while portable generators are a lower-cost, manual option for just the essentials.
- Properly size your generator for reliability: To find the right size, total the running watts of your essential appliances, add the single highest starting wattage, and include a 20% power cushion. This prevents overloads and ensures your generator runs efficiently.
- Prioritize safety with professional installation: A generator is not a DIY project. Hiring a licensed electrician is the only way to guarantee your system is installed safely, meets all local codes, and protects your family and expensive electronics from damage.
Standby vs. Portable: Which Generator Is Right for You?
When a power outage hits, having a backup plan is essential for keeping your family safe and comfortable. The two main choices for home backup power are standby generators and portable generators. Each comes with its own set of benefits, and the right one for you depends on your power needs, budget, and how much convenience you’re looking for. Making the right choice means you won't be left in the dark when the grid goes down. Let's break down the differences to help you decide.
What is a standby generator?
A standby generator is a permanent backup power solution that’s installed outside your home, similar to an air conditioning unit. It’s wired directly into your home’s electrical panel through a device called an Automatic Transfer Switch (ATS). This is the key to its convenience. The ATS constantly monitors the power from the utility company. The moment it detects an outage, it automatically disconnects you from the grid and starts the generator, restoring power to your home in seconds. You don’t have to lift a finger. This seamless transition makes standby generators the ultimate solution for uninterrupted power and total peace of mind, especially during severe weather or extended outages.
What is a portable generator?
A portable generator is a smaller, mobile unit that you can move to where you need it. Unlike a standby model, it requires manual setup every time you lose power. You’ll need to wheel it outside to a safe location (at least 20 feet from your house), start it up, and run heavy-duty extension cords to the appliances you want to power. While they are a much more affordable option upfront, they demand more effort during a stressful situation. They’re a great choice for powering just a few essentials like your refrigerator and some lights, but they require careful handling and safe storage to prevent carbon monoxide hazards.
Key differences at a glance
Choosing between a standby and a portable generator comes down to a few key factors: convenience, power, and cost. A standby generator offers ultimate convenience by turning on automatically, so your life is barely interrupted. A portable generator requires you to do all the work manually. In terms of power, standby models are workhorses, capable of running everything from your lights to your central air conditioner. Portables have a much lower output, designed to handle only essential appliances.
Of course, there’s the investment to consider. Standby generators are more expensive due to the equipment and professional installation, while portables are significantly cheaper. If you want a hands-off solution that powers your entire home, a standby model is the way to go. If you just need to keep the basics running and are comfortable with manual setup, a portable unit can get the job done. Our team can help with professional generator installation and repair for a safe, reliable setup.
How to Size a Generator for Your Home
Picking the right size generator isn't just about getting the power back on; it's about keeping your home running smoothly and safely. A generator that's too small will struggle to power your essentials, leading to frustrating overloads and shutdowns right when you need it most. On the other hand, one that's excessively large can be an unnecessary expense and may not run as efficiently. Finding that "just right" fit ensures your investment works perfectly for your family's needs, protecting both your appliances and your peace of mind.
Sizing a generator might sound technical, but it's a straightforward process. It all comes down to understanding what you want to power and how much electricity those items use. By following a few simple steps, you can confidently calculate your power requirements and choose a generator that will be a reliable partner during any outage. Think of it as creating a power plan for your home. We'll walk through how to list your essential appliances, calculate their power needs, and add a smart buffer to ensure you're always prepared. This way, you can face the next power outage with confidence, knowing your home is protected.
Step 1: List your must-have appliances
First things first, grab a notepad and walk through your house. Think about what you absolutely can't live without during a power outage. Your list might include the refrigerator and freezer to save your food, a few lights for safety, the Wi-Fi router to stay connected, and maybe a sump pump if you have a basement. If someone in your family relies on medical equipment, that goes to the top of the list. The goal is to identify the essential appliances you'll want to power at the same time. This simple list is the foundation for figuring out exactly how much power you'll need to keep your household running comfortably and securely.
Step 2: Calculate your running watts
Now that you have your list, it's time for a little math. Every appliance has "running watts," which is the amount of power it uses to operate continuously. You can usually find this number on a sticker on the appliance itself or in its owner's manual. To get a general idea, powering just the essentials like lights, a fridge, and Wi-Fi typically requires 3,000 to 5,000 watts. A partial house backup might need 7,000 to 12,000 watts, while a whole-house solution with central air can exceed 15,000 watts. Add up the running watts for all the items on your list to get your baseline power requirement. This total tells you the minimum continuous power your generator must provide.
Step 3: Factor in starting (surge) watts
Here’s a crucial step many people miss: accounting for starting watts. Appliances with motors, like your refrigerator, air conditioner, or well pump, need an extra jolt of power to get started. This is called "starting" or "surge" wattage. To properly size your generator, you need to add the highest starting wattage from a single motor-driven appliance to your total running watts. For example, if your fridge needs 700 running watts but 2,000 starting watts, you need to account for that initial surge. Ignoring this can cause your generator to overload and shut down just as it’s getting started, so be sure to factor it in for reliable performance.
Step 4: Give yourself a power cushion
Once you have your total wattage, the final step is to add a buffer. It’s wise to choose a generator that can handle more than your calculated minimum. Opting for a slightly larger generator means it won't have to run at maximum capacity all the time, which reduces strain and can extend its lifespan. This power cushion also gives you the flexibility to plug in an extra device or two without worry. A good rule of thumb is to add 20% to 25% to your total required wattage. This ensures your generator runs efficiently and you have the power you need, with a little extra just in case. Regular maintenance through a VIP membership can also keep your perfectly sized generator ready for anything.

Breaking Down the Cost of a Home Generator
Understanding the cost of a home generator is a major step in deciding which option is right for your family. The final price tag isn't just about the generator unit; it also includes installation, permits, and any necessary upgrades to your home's electrical system. Let's break down the numbers so you can get a clear picture of the investment and find a solution that fits your budget and your needs.
Portable generator price range
A portable generator is the most budget-friendly option upfront. You can expect the unit itself to cost anywhere from $800 to $2,500. This price range typically gets you a generator that provides between 3,000 and 15,000 watts of power. While the initial cost is lower, remember to factor in the manual effort required. During an outage, you’ll need to move the generator outside, start it up, and run extension cords to your essential appliances. It’s a practical choice for powering a few key items, but it requires hands-on management every time you use it.
Standby generator investment
A standby generator is an investment in automatic, whole-home power and peace of mind. The total installed cost for a standby system typically ranges from $7,000 to $15,000. This price covers a complete, seamless solution: the generator unit, a transfer switch that automatically kicks on, professional installation, and connection to your home’s fuel source. When you invest in one of these permanent generators, you’re getting a reliable system that keeps your lights on and your family safe without you having to lift a finger.
Factoring in installation and other costs
Several factors influence the final price of a standby generator installation. The size of the generator you need is the biggest variable, as a larger home with more appliances requires a more powerful unit. The complexity of the installation also plays a role. For example, the location of the generator on your property, its distance from the fuel source, and the condition of your current electrical panel can all affect labor costs. This is why a professional on-site assessment is so important; it ensures you get an accurate, upfront quote with no surprises.
Exploring your financing options
We understand that a standby generator is a significant home improvement project. That average cost of $7,000 to $15,000 can feel like a lot to handle all at once. The good news is you don't have to. Many homeowners choose to finance their generator installation to make the investment more manageable. This allows you to get the security and comfort you need now while paying for it over time with predictable monthly payments. We believe every family deserves to feel secure during a power outage, which is why we offer flexible financing options plans to help fit this essential upgrade into your budget.
Must-Have Features for Your Home Generator
Once you know the right size and type of generator for your home, it’s time to look at the features that make a real difference in convenience, safety, and performance. The right combination of features ensures your generator isn’t just a machine in your yard, but a reliable source of power that seamlessly protects your home and family during an outage. From automatic operation to smart monitoring, these are the details that provide true peace of mind.
Choosing your power output and fuel type
First, let’s match the generator’s power to your family’s needs. You can calculate this by adding up the wattage of everything you want to run simultaneously. A smaller generator (3,000 to 5,000 watts) can handle essentials like the fridge, lights, and Wi-Fi. For partial home backup, you’ll want something in the 7,000 to 12,000-watt range. If you need to power everything, including your A/C, you’ll need a whole-house unit with 15,000 watts or more.
Next, consider your fuel source. Most standby generators run on natural gas or liquid propane. Natural gas is incredibly convenient because it hooks directly into your utility line, providing a virtually endless supply. Propane is stored in a large tank on your property and also offers a long runtime before needing a refill.
The convenience of an automatic transfer switch
An automatic transfer switch (ATS) is the key to effortless power backup. This device connects your standby generator directly to your home’s electrical panel. When it detects a power outage, it automatically disconnects you from the grid and signals the generator to start, restoring power to your home in seconds. You don’t have to do a thing.
This hands-off operation means no more searching for flashlights or fumbling with extension cords in the dark. The ATS handles the entire process safely and seamlessly, ensuring your home’s essential systems are running before you even notice the power is out. Since it integrates with your home’s main electrical system, a professional should always handle the panel work.
Considering noise levels and runtime
No one wants a generator that sounds like a jet engine in their backyard. Noise level is a major factor for your comfort and your relationship with your neighbors. Many modern generators, especially inverter models, are designed to run much quieter than older units. They also produce “cleaner” power, which is safer for sensitive electronics like computers and TVs.
Runtime is determined by your fuel source. As mentioned, a generator connected to your home’s natural gas line can run indefinitely as long as the gas is flowing. If you opt for a propane model, the size of your tank will determine how long it can run before a refill is needed. Regular tune-ups as part of a VIP membership can also ensure your generator runs as efficiently as possible.
Smart features, safety, and warranty
Today’s generators come with smart features that give you more control and insight. Many models are Wi-Fi enabled, allowing you to monitor your generator’s status from your phone, whether you’re home or away. This is perfect for checking fuel levels or confirming the system is ready for a storm.
Safety should always be your top priority. A critical feature to look for is a built-in carbon monoxide (CO) sensor that automatically shuts the generator off if CO levels become dangerous. Finally, a strong warranty is a must. It protects your investment and ensures you have support if anything goes wrong. Professional installation of your generator guarantees that all these features, especially the safety mechanisms, are set up correctly from day one.
Why Professional Installation Is a Smart Investment
Buying a generator is the first step toward securing your home’s power supply, but the most critical part is the installation. While it might be tempting to save money with a DIY approach, installing a generator is a complex electrical project that’s best left to a professional. A proper installation ensures your generator operates safely and effectively, integrating seamlessly with your home’s existing electrical system. It’s not just about plugging something in; it’s about safeguarding your home, your appliances, and your family.
A licensed electrician handles every detail, from securing the right permits to making sure the unit is perfectly calibrated for your home’s needs. This initial investment in professional service pays off by preventing costly repairs, ensuring your warranty remains valid, and giving you complete confidence that your power will be there when you need it most. When you work with a trusted expert, you’re not just buying a machine; you’re investing in a reliable, long-term solution for your family’s comfort and safety.
Navigating permits and electrical codes
One of the biggest hurdles in generator installation is dealing with local permits and electrical codes. These regulations are in place to ensure safety, and they can be complex and specific to our Sacramento area. A professional electrician is already familiar with these requirements and will manage the entire permitting process for you. They can also assess if your home’s current electrical system, particularly the panel, can handle the new load or if it needs an upgrade. Getting this right from the start helps you avoid potential fines, failed inspections, and the major headache of having to redo the work later. It’s all about ensuring your installation is safe, compliant, and built to last.
Protecting your home, family, and appliances
An improperly installed generator poses serious risks, including electrical fires, carbon monoxide poisoning, and back-feeding, which can endanger utility workers. Professional installation is essential for generator safety and is the best way to protect what matters most. A licensed technician will ensure your generator is placed correctly with proper ventilation, connected safely to your home’s electrical system, and equipped with a transfer switch to prevent dangerous power surges. This protects your sensitive electronics, like computers and TVs, from damage and gives you peace of mind knowing your backup power system won’t create a hazard for your family. It’s a crucial step for a truly secure and reliable power solution.
Keeping your generator ready with regular maintenance
Your generator is a machine that needs to be ready at a moment’s notice, and professional installation sets you up for long-term success. An expert installer will not only get your system running but can also guide you on the routine maintenance needed to keep it in top condition. Just like your car, your generator requires periodic checks to ensure it remains a reliable source of backup power.

Frequently Asked Questions
What happens if I choose a generator that's too small for my home? Choosing a generator that's too small can cause frustrating problems right when you need power the most. The generator will likely overload and shut down, leaving you in the dark. This happens because it can't handle the combined power demand of your appliances, especially the extra surge needed to start items like a refrigerator. Consistently overloading a generator can also cause unnecessary strain on the machine and potentially damage the sensitive electronics you have plugged into it. This is why taking the time to properly calculate your wattage needs is such a critical step.
A standby generator sounds great, but is a portable one "good enough" for most outages? A portable generator can absolutely be a good solution, as long as you’re comfortable with what it entails. If you just want to keep the refrigerator cold, a few lights on, and your phones charged, a portable unit can get the job done. The trade-off is convenience. You will need to manually set it up, run extension cords, and refuel it during the outage. A standby generator is for homeowners who want a seamless, automatic solution that powers large portions of their home (or the whole thing) without any manual effort, which is especially valuable during extended outages or for families with medical equipment.
How long does a professional generator installation typically take? A standard standby generator installation is usually completed within one full day. The process is quite thorough, which is why it’s a job for a professional. It involves preparing the site, setting the generator on a concrete pad, and then making the crucial electrical connections. This includes installing the automatic transfer switch and wiring it into your home’s main electrical panel. Finally, the technician connects the fuel line and tests the entire system to ensure it works perfectly.
I see options for natural gas, propane, and gasoline. Which fuel type is best? The best fuel type really depends on your home's setup and your priorities. For standby generators, natural gas is the most convenient option because it connects directly to your utility line, offering a virtually endless supply. If you don't have access to natural gas, liquid propane is an excellent alternative; it's stored in a large tank on your property and also provides very long runtimes. Gasoline is primarily used for portable generators and requires you to store it safely and keep it fresh, which can be a challenge during an emergency.
Do I really need to maintain my generator if I only use it a few times a year? Yes, regular maintenance is essential for ensuring your generator will work when you need it. Think of it like your car; even if you don't drive it often, it still needs oil changes and tune-ups to stay reliable. A generator has a motor and moving parts that need to be checked periodically. Most standby models run a weekly self-test, but an annual professional inspection is key to catching any potential issues, checking fluid levels, and making sure the battery is ready to go. This proactive care is the best way to protect your investment and guarantee it will start without a problem during the next outage.
