Can a Backup Generator Keep Your AC Running in a Storm?
Florida is the Sunshine State for a good reason. It enjoys over 230 sunny days each year, on average. But the state is no stranger to thunderstorms and hurricanes. In fact, the state usually gets hit by at least one to two hurricanes each year.
When the power goes out, like it often does, it’s imperative to have backup power in place during a storm or hurricane to keep your home comfortable. When outages occur during heat waves, you’ll appreciate being able to keep your AC running. This is why so many homeowners choose to install generators. But not just any generator will do. You need one with certain features, like voltage protection and sufficient wattage capacity, to ensure your system operates safely and without overload.
Understanding all of the different options is an excellent way to select a backup generator that will fully meet your needs. It also helps to have a consult with a company like Mister Sparky that specializes in backup generator installations.
Can a Generator Run Your AC?
Air conditioners are appliances that constantly turn on and off. Their starting wattage alone demands a significant amount of power to kick the system into operation. Pair this with their continuous cooling demand and you can see why they require a much larger power source than most household appliances. Whether or not your generator can power the AC during an outage depends on its type and size. Portable units work best with smaller appliances, like fans or refrigerators. A whole-home generator is what you need to keep the AC running without interruptions.
Understanding AC Power Requirements
A central AC has two primary wattage needs: starting watts (3,000 to 6,000 watts) and running watts (1,500 to 4,000 watts). These wattages determine the size generator you need.
Portable generators only provide 2,000 to 5,000 watts. This is why they don’t work well for keeping a central AC running during a power outage. A whole-home generator, on the other hand, can provide wattage up to 20,000 watts or more, depending on the type you purchase. This is plenty of power to keep multiple major appliances running at the same time, including a central AC.
Choosing the Right Generator for AC Use
A portable generator may be sufficient for running a window AC unit but not a central cooling setup. The starting wattage often exceeds the generator’s available surge capacity, preventing the AC from being able to turn on.
For a central AC, you need to consider its tonnage to choose the right size whole-home generator:
- 1.5–2 tons: 12,000–18,000 watts
- 2.5–3 tons: 18,000–22,000 watts
- 3.5–4 tons: 22,000–26,000 watts
When you don’t size the generator correctly, you make the AC vulnerable to power surges and premature equipment failure. Working with licensed electricians who specialize in generators is a smart move for picking the best backup generator for your needs.
Benefits of Running Your AC During a Storm Outage
When the power goes out, the last thing you want to stress about is trying to stay cool and comfortable. With a generator, you can keep the AC running so the whole house stays safe and livable.
- Better temperature and humidity
- Reduced mold and moisture issues
- Safer conditions during extreme heat
- Greater comfort for vulnerable family members
Fuel Source Considerations
Choosing the correct fuel source is as important as selecting the right size generator. You have three main options to choose from: natural gas, propane, and diesel.
Each type offers varying runtimes for powering your AC during an outage:
- Natural gas: Unlimited runtime as long as the utility supply remains active.
- Propane: Runtime depends on tank size.
- Diesel: Requires regular refueling during extended outages.
Why Professional Installation Matters
You don’t just plug in a whole-home generator. It requires connecting the device to your electrical panel to keep all of your circuits and essential appliances running during outages. Professional installation matters because it guarantees safe connections to the panel. Plus, we’ll confirm the generator’s compatibility with your air conditioner so you don’t install the wrong type.
Furthermore, we’ll install the transfer switch, which is the component that controls where your home draws power from: either the utility power or generator. You won’t have to worry about electricity backfeeding into utility lines when the backup generator is running. This reduces fire risk and also keeps the home safer by protecting circuits and preventing accidental overloads.
When to Upgrade Your Electrical System
No matter the type of generator you choose, you may need to make certain upgrades to your electrical system. Older panels often limit AC compatibility because of their lower amperage capacity. Letting us install a new panel with modern wiring, breakers, and updated safety features is a smart upgrade. The panel will have everything it needs to safely handle the added load from the generator.
