A generator can supply the lights and appliances in your Annapolis, Maryland, home with power after a severe storm or another emergency. There are many different models available, but before you choose a generator, make sure you consider all of its features. Think about the capacity, the cost, and the type of generator you need to make sure you find the best one for you and your family.


A whole-home generator can provide power for your entire home, including your HVAC system. Many models will switch on automatically if the power goes out. This feature protects your home from mold and mildew by keeping your HVAC system running.

With a portable generator, you’ll need to attach appliances with an extension cord to use them. However, a portable unit is great for camping, tailgate parties and other activities away from a reliable power source.


Whole-home generators are more expensive than portable models because of their higher capacity. A professional must install the generator in your yard on a concrete pad and connect it to your home’s electrical system. You’ll also need to use more fuel. You can store a portable unit in your garage or a storage shed until you need it instead of paying to install a whole-home unit. 

Fuel Type

Many types of generators are available, including natural gas, propane, diesel and gasoline. Natural gas models don’t require refueling, so many whole-home generators use this fuel. Diesel is efficient, but it usually makes more noise. Propane generators are quieter, but the fuel is more expensive than many other type. Gasoline is often easy to find, but it’s difficult to store safely. Make sure you can get the fuel you need in an emergency or store enough to last for a few days.
