What Size Generator To Run Furnace And Refrigerator

Okay, let's talk generators. Not the boring kind. We’re diving into the quest: powering your furnace and refrigerator when the lights go out. It's a survival skill, really.

The Great Power Outage Panic

Picture it: the wind howls, trees dance dangerously, and then… darkness. Your furnace coughs its last breath. The fridge starts its slow descent into lukewarm chaos.

Suddenly, generator size becomes a life-or-death question (okay, maybe not life-or-death, but definitely comfort-or-misery). So, what size generator do you actually need? Prepare yourself. My answer might be…controversial.

Forget Overkill, Embrace Reality (and Extension Cords)

Everyone shouts "Bigger is better!" in generator-land. They scream about surge watts and continuous watts. It's like they're trying to sell you a monster truck for driving to the grocery store. My opinion? It's generally wasteful.

Here's my (unpopular) opinion: Unless you're running a hospital, a small generator might be your best friend. Think portable, easy to start, and relatively fuel-efficient.

Decoding the Wattage Mystery

First, the fridge. Check the label inside. Find the "running watts" or something similar. It's usually surprisingly low. Most standard refrigerators only need around 150-200 watts to keep running.

The furnace is a bit trickier. It's the inducer fan motor that matters most. Look at the nameplate on the furnace itself. That will tell you the motor's amp draw.

Multiply those amps by 120 (standard household voltage). That gives you the running watts needed for the furnace fan. It is typically somewhere between 600 and 800 watts.

The "Add It All Up" Myth

So, you add the refrigerator's 200 watts to the furnace's 800 watts. You get 1000 watts, right? You now need a 1000-watt generator? Not so fast, my friend!

The fridge cycles on and off. The furnace blower might only kick on periodically. They aren't constantly demanding power at the same time.

Here's where I get heretical: A good quality 2000-watt (surge) / 1600-watt (continuous) generator might just be enough. Yes, I said it!

Why I'm Sticking to My (Small) Guns

A smaller generator is lighter. You can actually move it. Imagine lugging a giant generator out of the shed in the dark. No fun.

Smaller generators are often quieter too. Your neighbors (and your sanity) will thank you.

They sip fuel, not guzzle it. During a prolonged outage, fuel becomes precious. You will be glad you're not burning gallons per hour.

The Extension Cord Tango

Here's the trick (and the part that makes some generator snobs shudder): Extension cords. Yes, plural.

Run one heavy-duty extension cord to your fridge. Run another to the furnace. This allows you to only power those essential items.

You're not trying to run your entire house. You're trying to survive. And maybe watch some Netflix on your laptop. (Okay, maybe not.)

Addressing the Haters (and the Surge)

I know, I know. The surge! Everyone worries about the surge. Appliances need extra power to start.

A decent quality 2000-watt surge generator should handle the fridge and furnace fan startup. It will grunt a little, but it should manage.

If you're really worried, stagger the starts. Turn on the fridge first. Wait a few minutes. Then fire up the furnace. Problem solved.

The Unpardonable Sin: Ignoring Safety

Before anyone yells at me, let's be clear: Safety first. Always!

Never run a generator indoors or in an enclosed space. Carbon monoxide is a silent killer. I will repeat: Never, Ever!

Use heavy-duty extension cords. Don't overload circuits. And read the generator's instruction manual. Seriously.

The Bottom Line (and My Final Heresy)

You probably don't need a generator the size of a small car to run your furnace and refrigerator. A 2000-watt (surge) unit will likely suffice.

Embrace the extension cord. Conserve fuel. And enjoy the relative peace and quiet. You will have less to worry about in tough situations.

Now, if you'll excuse me, I'm going to go hide from the generator purists. My unpopular opinion might just get me banished.

The Inverter Generator Advantage

Let's talk about inverter generators. These are generally quieter and more fuel-efficient than traditional generators. They also produce cleaner power.

This "cleaner" power is important for sensitive electronics. Think laptops, phones, and modern appliances with electronic controls. It's another strong point for a smaller inverter generator.

An inverter generator smooths out the power output. It adapts to the load, providing only what is needed at any given moment.

Beyond the Basics: A Few Extra Tips

Consider a generator with an automatic low-oil shutoff. This can prevent engine damage if the oil level gets too low.

Test your generator regularly. Don't wait until the power goes out to discover it won't start. Regular maintenance is essential.

Store extra fuel safely. Use a proper fuel container. And keep it away from heat sources.

Think Strategically, Not Overkillishly

The key is to think strategically about what you need to power. Don't get caught up in the "what if" game.

Focus on the essentials: keeping your food cold and your home (relatively) warm. A smaller generator can handle that, with a little planning.

Remember, a generator is a tool, not a status symbol. Choose the right tool for the job. And don't be afraid to challenge conventional wisdom.

Debunking Generator Myths

Myth #1: You need a generator that can power your entire house. Reality: You only need to power essential appliances.

Myth #2: A larger generator is always more reliable. Reality: A well-maintained smaller generator is often more reliable than a neglected behemoth.

Myth #3: Surge watts are the only thing that matters. Reality: Continuous watts are just as important, if not more so, for sustained operation.

My Last Stand: Smaller Is Smarter

I stand by my (possibly crazy) belief that a smaller generator is often the better choice for home backup power, especially if you're only concerned with running your furnace and refrigerator.

It's practical, economical, and manageable. It's a tool that empowers you, not burdens you.

So, go forth and choose wisely. And remember, if the power goes out, you'll be the one laughing (quietly, of course, because you have a nice, quiet generator).
