Understanding Whole Home Generators
Whole home generators keep your life moving even when the power takes a hike. They jump in, like a trusty sidekick, making sure your power-hungry gadgets and crucial systems don’t skip a beat during those annoying outages.
Importance of Whole Home Generators
These generators are a game-changer for keeping your home snug and secure when the lights go out. Whether it’s holding the fort with the lights, making sure the heat or AC is still kicking, or keeping medical gear online, they bring a comforting sense of continuity. In places like Houston, TX, where the weather can be wild and unpredictable, a solid generator isn’t just nice to have—it’s a must for dodging the chaos and hazards of long blackouts.
Why Proper Sizing is Crucial
Picking the right sized generator is a bit like Goldilocks looking for the perfect porridge—not too small, not too big, but just right. If it’s too tiny, it might end up wheezing under the pressure and could even mess up your stuff. Too big, and you’re just burning cash and fuel for no reason. Getting it spot-on involves jotting down what your home really eats up in terms of power—like figuring how many watts each of your beloved appliances need to kick off and keep running. If you’re scratching your head wondering how to figure this all out, our handy generator sizing calculator or whole house generator wattage calculator can act as your guide.
Nailing the perfect size not only makes your generator hum smoothly but keeps it happy and healthy for years, sipping fuel like a Prius. Once you grasp why sizing really matters, you’ll score a generator that ticks all your boxes without breaking a sweat.

Factors for Sizing a Whole Home Generator
Choosing the right generator isn’t just about making sure the lights stay on during the next big storm; it’s about finding one that fits just right, like Cinderella’s slipper. To get it spot on, think about your house size, how much juice everything needs, and what kind of fuel you’re comfortable with.
Home Size and Layout
Your house’s square footage and the way it’s laid out are big pieces of the puzzle. Bigger homes tend to suck up more power, and your house’s unique setup might mean some gadgets and areas need more priority.
| Home Size (sq ft) | Estimated Power Needs (kW) |
|---|---|
| 1,000 – 1,500 | 14 – 20 |
| 1,500 – 2,500 | 20 – 24 |
| 2,500 – 3,500 | 24 – 30 |
| 3,500+ | 30+ |
If your house stretches over several floors or has sprawling outdoor spaces, you might need extra kick for outdoor lights and heaters. Use our nifty generator sizing calculator to get a clearer picture.
Electrical Load
This bit is about figuring out the total power all your gadgets and appliances need. You’ll want to look at both running watts (how much power they use while operating) and starting watts (the power needed to get motor-driven appliances, like fridges, up and running).
| Appliance | Running Watts | Starting Watts |
|---|---|---|
| Refrigerator | 800 | 1,200 |
| Central AC (24,000 BTU) | 3,800 | 4,500 |
| Heater | 1,500 | 1,500 |
| Washing Machine | 1,150 | 2,300 |
Don’t sweat the numbers too much—let our whole house generator wattage calculator do the heavy lifting.
Fuel Source Considerations
Deciding on the fuel type is like picking between coffee, tea, or soda—each has its perks and quirks. The fuel you choose can change how much you spend on running your generator, how often it’s maintained, and how efficiently it runs.
| Fuel Type | Pros | Cons |
|---|---|---|
| Natural Gas | Always available, runs clean | Might not work during gas line issues |
| Propane | Doesn’t spoil, burns like a dream | Needs tank storage |
| Diesel | Packs a punch, easy to find | Loud, can be dirty |

Putting all these puzzle pieces together will make sure you don’t end up in the dark next time you really need power. For the nitty-gritty on wattage calculations, our guide on calculating generator size for home has everything you need.
Calculating Generator Size
Picking the right-sized generator for your whole house is like finding the right puzzle piece. It’s gotta fit just right to keep everything running smoothly when the power decides to bail on you. Getting this right means figuring out how much juice your place needs—think of it as totaling up the watts, the steady kind and the ‘let’s get this thing moving’ starting ones.
Calculating Total Wattage Needs
Step one is figuring out how much power your home craves. Start by listing out all the must-have gizmos and gadgets along with their watt gobbling habits.
Common Household Appliances and Their Wattage:
| Appliance | Running Watts | Starting Watts |
|---|---|---|
| Refrigerator | 700 | 2200 |
| Air Conditioner (3 ton) | 3500 | 7200 |
| Electric Water Heater | 4500 | 0 |
| Microwave Oven | 1000 | 0 |
| Washing Machine | 1200 | 2400 |
| Television | 200 | 0 |
| Lights (10 Bulbs) | 600 | 0 |
Round up all the steady running watts for the stuff that’s gonna be buzzing at the same time. Check out our whole house generator wattage calculator for some extra hand-holding.
Accounting for Starting Watts vs Running Watts
Starting watts are like the first push you need to get motor-driven stuff going. Your generator’s gotta be ready to handle that initial ‘oomph’ to do its job right.
Example: Wattage Calculation
| Appliance | Running Watts | Starting Watts |
|---|---|---|
| Refrigerator | 700 | 2200 |
| Air Conditioner (3 ton) | 3500 | 7200 |
| Electric Water Heater | 4500 | 0 |
| TOTAL | 8700 | 9400 |
Here, your house settles in at 8700 running watts, but don’t forget about those 9400 watts needed when things start spinning up.

Making sure you count both running and starting watts means your new power pal can keep everything from your fridge to your A/C humming along happily. Want to dig deeper? Our residential generator sizing guide is just the ticket.
