Unexpected power outages can bring everything to a halt. It’s not just about the lights. Your heating, cooling, fridge, and even your home security may go dark in a flash.

At Platts Heating & Air, we know how unsettling that can feel. Homeowners like you depend on steady power, especially during storms or emergencies. Let's break down what you need to know about home generator installation—so you can weather any storm with confidence.

Why Install a Home Generator? ⚡

Picture this: A storm rolls in. Wind howls, lightning cracks. Suddenly, your house plunges into darkness. No heat. No AC. The food in the freezer starts thawing. The sump pump goes silent. It's more than an inconvenience—it can put your comfort and safety at risk.

Here’s why a generator makes sense:

  • Storm Prep: Storms, ice, and high winds can knock out power for hours or even days.
  • Home Security: A blackout can disarm alarms and leave your home vulnerable.
  • Medical Needs: Refrigerated medications or powered equipment need reliable electricity.
  • Comfort: Keep radiant heating, AC, and appliances running when the grid goes down.

The U.S. Department of Energy estimates millions face outages each year, especially with severe weather on the rise. A generator is your safety net.

Types of Generators

Not all generators are created equal. Like picking the right tool for a job, you'll want to match your generator to your needs.

Portable vs. Standby

  • Portable Generators:

    • Moveable, smaller, and typically less expensive.
    • Power a few essentials (fridge, sump pump, heater).
    • Require manual setup and fueling.
    • Downside: Need to be run outdoors and never inside a garage or basement due to deadly carbon monoxide.
  • Standby Generators:

    • Permanently installed outside the home.
    • Automatic—kick in when the power cuts out.
    • Can power your whole house or select circuits.
    • Run on natural gas or propane, so no refueling in the rain.

Fuel Options

  • Gasoline: Easy to find, but short shelf life.
  • Propane: Clean-burning, stores well, but needs a tank.
  • Natural Gas: No refueling, but requires a gas line.
  • Diesel: Reliable, but noisier and bulkier.

Sizing: How Big Should You Go?

Think of sizing like packing for a trip. Too little, and you’ll leave essentials behind. Too much, and you’re lugging around what you don’t need.

  • List out must-have appliances (fridge, heating, medical).
  • Check their wattages. Add them up.
  • Add 20% for startup surges.

Safe Installation Practices 🛑

A generator is a powerful piece of equipment. Install it wrong, and it can be dangerous for you and your neighborhood.

Permits and Codes

  • Local Permits: Most areas require permits. Skipping this risks fines—or worse, insurance denial after an accident.
  • Code Compliance: National Electrical Code (NEC), National Fire Protection Association (NFPA) standards, and local ordinances set the rules.
  • Licensed Electrician: Always use a licensed electrician for the hookup. Not just for the paperwork—your safety is on the line.

Location, Location, Location

  • Outdoors Only: Generators produce carbon monoxide—an odorless, deadly gas.
  • Clearances: At least 5 feet from doors, windows, and vents.
  • Solid Surface: Keep it level and dry, away from pooling water or debris buildup.

Pro Installation: Why It Matters

  • Properly sized wiring and transfer switches prevent overloads and backfeeding (which can threaten utility workers).
  • Gas lines must be sealed and tested for leaks.
  • Our team partners with licensed electricians to ensure every generator install is safe, legal, and reliable.

Ongoing Maintenance

A generator is like a car—you can’t just park it and forget it.

Routine Testing

  • Run Weekly: Even if you don’t need it, run your generator for 10–15 minutes each week.
  • Listen for Odd Noises: Rattles, knocks, or stutters mean it’s time for a checkup.

Fuel Checks

  • Propane/Natural Gas: Inspect tanks for leaks and corrosion.
  • Gasoline: Use fuel stabilizer; always rotate fresh fuel.

Professional Service

  • Annual inspections: Test batteries, change oil and filters, check electrical connections.
  • Keep a maintenance log. It’s your proof of care for insurance and warranty claims.

The National Fire Protection Association (NFPA 110) and manufacturer guidelines offer more on safe generator upkeep.

Safety Checklist: Before, During & After Use

  • [ ] Only use outdoors, 5+ feet from openings.
  • [ ] Keep dry and off the ground.
  • [ ] Never plug into a wall outlet (danger of backfeeding).
  • [ ] Use heavy-duty, outdoor-rated extension cords.
  • [ ] Store fuel safely in approved containers.
  • [ ] Test carbon monoxide detectors in your home.

DIY vs. Call a Pro

It’s tempting to DIY. But generator wiring isn’t like swapping out a lightbulb.

  • DIY Risks: Electrical shock, fire, gas leaks, code violations.
  • Pros Bring: Licensed expertise, code compliance, and a full safety checklist.

For most homeowners, calling an emergency hvac or electrical pro is peace of mind you can’t put a price on.

What Pros Do On Arrival

  • Assess your power goals (essentials vs. whole-house).
  • Perform a home energy audit.
  • Advise on generator type, fuel, and size.
  • Secure permits and inspections.
  • Install transfer switches for automatic operation.
  • Test the setup—every circuit, every load.

Prevention & Maintenance

Prevention is the best insurance. Here’s how to keep your generator ready:

  • Monthly: Visual checks, clear debris, test run.
  • Quarterly: Inspect fuel and oil levels.
  • Annually: Full professional service.
  • After Every Use: Let it cool, wipe down, and refill fuel if needed.

Don’t forget—change air filters and check for rodent nests, especially before storm season.

Costs & Time Factors

How much will it cost? It depends on your needs, home size, and generator type.

  • Portable Generators: Lower upfront cost, but manual setup and limited capacity.
  • Standby Generators: Higher investment, but seamless power and higher property value.

Time Factors:

  • Permitting and inspections can take days to weeks.
  • Installation: Usually 1–2 days for standby systems.
  • Maintenance: 1–2 hours per visit.

Remember: The cost of spoiled food, frozen pipes, or lost work during outages often far outweighs the upfront investment.

When It’s an Emergency 🚨

If your power is out, and you need heat, AC, or medical equipment now, call for 24 hour emergency hvac help. Never risk DIY fixes in the dark.

Frequently Asked Questions

How do I know what size generator I need?
List your must-have appliances and their wattage. A pro energy audit gives you the most accurate answer.

How often should I run my generator?
Test it weekly and after every outage. Don’t let it sit unused for long periods.

Is it safe to install a generator myself?
For portable units, follow the manual to the letter, but all standby systems should be installed by licensed pros. Mistakes can be deadly.

What’s the lifespan of a home generator?
With proper maintenance, standby generators often last 10–20 years.

Local & Seasonal Considerations

When the weather turns, radiant heating near you and reliable backup power are more than luxuries—they’re essentials. Winter storms and summer heat waves both strain the grid. Schedule your installation before peak season for the smoothest experience.

Check local rules—some areas require noise controls or restrict generator types. Our team stays current on all local and national codes so you don’t have to worry.
