Storms, outages, and random blackouts aren’t just inconvenient; they can seriously disrupt your home and routine. That’s why more homeowners are turning to backup power solutions. But before you shop for a generator, any seasoned Seattle generator installer will tell you it’s worth knowing the common traps people fall into.
Picking the right setup takes more than just grabbing something off the shelf. That said, let’s walk through the eight most common mistakes people make (and how to avoid them).
Mistake #1: Underestimating How Much Power You Need
This is the most common mistake: thinking a small, portable generator will magically power your entire home. Unfortunately, that’s not how it works.
Every appliance, light, and device in your home requires a certain amount of wattage. Add those up, and you’ll quickly realize your power needs are higher than you thought — especially if you want to keep essentials like your fridge, sump pump, HVAC, or well pump running.
Solution:
Make a list of the items you want to power during an outage, then check their wattage. Multiply startup wattage for large appliances (they need more power to start than to run). Use this list when shopping or talk to a generator pro for help with sizing. A licensed electrician or generator installer can calculate your total load and recommend the right unit.
Mistake #2: Focusing Only on Price, Not Long-Term Value
We get it — generators aren’t cheap. However, choosing the lowest-priced option can backfire quickly if it doesn’t meet your needs, is hard to maintain, or breaks down too soon.
The real value of a generator comes from reliability, fuel efficiency, and ease of use, not just the price tag.
Solution:
Look for a generator that balances quality with cost. Read reviews, compare warranty coverage, and consider the brand’s reputation. Think long-term: a solid generator might cost more upfront but save you money in fuel and repairs later.
Mistake #3: Choosing the Wrong Type of Generator
There are two main types of generators for home use: portable and standby. A lot of homeowners buy one without fully understanding what it can (and can’t) do.
Portable generators are affordable and flexible, but they usually power only a few essentials and must be manually operated (and refueled). Standby generators are permanently installed, automatically kick on during outages, and can power most or all of your home — but they’re a bigger investment.
Solution:
Ask yourself how much convenience, power, and coverage you want. If you’re okay with plugging things in manually and refueling every few hours, a portable might work. But if you want full-home backup and zero hassle during an outage, a standby generator is worth considering.
Mistake #4: Not Thinking About Fuel Type
Generators typically run on gasoline, propane, natural gas, or diesel. Each fuel type has pros and cons: some are easier to store, others burn cleaner, and some are better for long-term use.
Many homeowners buy a generator and only afterward realize they have nowhere to store gasoline, no propane hookup, or no access to natural gas.
Solution:
Before you buy, decide which fuel is most practical for your home. If you already have a natural gas line, a standby generator that hooks into it could be the most convenient. No gas line? Propane might be better. Just make sure you can easily and safely store the fuel required.
Mistake #5: Overlooking the Installation Requirements
Buying the generator is just part of the story; installing it is where many surprises pop up. Some standby generators require permits, utility approval, and a licensed electrician. Even portable units need proper setup and safety precautions.
Skipping this step or hiring someone unqualified can lead to serious issues, from code violations to electrical hazards.
Solution:
Plan for installation from the start. For standby generators, talk to a local pro who can assess your home, handle permits, and ensure everything is installed safely and up to code. Portable generators should at least have a transfer switch installed to avoid backfeeding and other safety risks.
Mistake #6: Ignoring Noise Levels
Have you ever tried sleeping while a loud generator hums just outside your window? Some homeowners are shocked at how noisy their new generator is, especially with cheaper or older models.
Noise might not seem like a big deal… until your neighbors start complaining or you’re trying to get through a week-long outage.
Solution:
Check the decibel (dB) rating on the unit before buying. Some generators, especially inverter models, are designed to run quieter. You can also ask about placement options and sound enclosures to keep things peaceful for you and everyone nearby.
Mistake #7: Forgetting About Maintenance
Like any major appliance, generators need regular care. That includes oil changes, air filter replacements, fuel stabilizers (for gasoline models), and routine inspections.
Homeowners often buy a generator and leave it untouched in the garage until the next storm. Then, when they need it most — it won’t start.
Solution:
Follow the manufacturer’s maintenance schedule. If it’s a standby generator, sign up for a maintenance plan with your installer. For portables, start and run the generator every few months to keep it in working order. Remember to keep extra oil and filters on hand, too.
Mistake #8: Not Being Prepared When the Power Actually Goes Out
This is the ultimate facepalm moment: you invested in a generator but don’t have the fuel, extension cords, or know-how ready when the lights go out.
In an emergency, every minute counts. The last thing you want is to stumble around in the dark, trying to figure out your setup.
Solution:
Do a trial run!
Practice setting up and starting your generator before you actually need it. Store fuel safely and keep everything in a designated spot. For standby generators, double-check that the automatic transfer switch is working and that the unit starts during regular test cycles.
Bonus Tip: Work with a Local Generator Pro
If you’re in the market for a generator, working with a Seattle generator installer can save you a ton of stress (and money) down the line. While you could try to go it alone, having someone who knows the area, the regulations, and the quirks of local homes makes all the difference.
Here’s what to look for in a generator expert:
Licensed and Insured
First things first, make sure they’re fully licensed and insured. This protects both you and your home if anything goes sideways during installation or service.
Knowledge of Local Codes & Permits
A reputable local installer will know what’s required to get your generator up and running legally. That includes handling permits, coordinating with utility companies, and making sure everything meets Seattle’s specific building codes.
Experience with Your Home Type
Whether you live in a downtown condo, a suburban craftsman, or a rural property, you want someone who’s familiar with installing generators in homes like yours.
Fuel Source Expertise
A good local pro will walk you through your best fuel options — whether that’s natural gas, propane, or diesel — based on what’s available and reliable in your neighborhood.
Maintenance & Support Options
Ask if they offer ongoing maintenance plans. A great generator installer won’t just set it and forget it; they’ll ensure your system stays in tip-top shape year-round.
Strong Reviews & Local Reputation
Word-of-mouth goes a long way. Look for a company with solid reviews, local references, and a track record of satisfied customers.
