Maryland winters can knock out power. Ice storms, heavy wet snow, and high winds bring down limbs and lines, and outages tend to strike when you need heat and power the most. A standby generator is only as good as its readiness, so the time to make sure yours will start and run is before the first big winter storm, not during one.

Here is how to get your Maryland home’s generator ready for winter.

Why winter readiness matters

Winter outages are often the longest and most dangerous of the year, because cold weather adds the risk of frozen pipes and loss of heat on top of the usual inconvenience. A generator that has sat unused since the last storm can fail to start when called on, leaving you without power in exactly the conditions where it matters most. A little preparation turns your generator from a hopeful backup into a reliable one.

Schedule a maintenance check

The foundation of readiness is service. Before winter, have your generator checked and maintained, which typically includes:

• Changing the oil and filter as needed
• Inspecting and replacing the air filter
• Checking the spark plug and battery
• Inspecting fuel lines and connections
• Confirming the transfer switch operates correctly

A weak battery is one of the most common reasons a standby generator fails to start in the cold, so battery condition deserves particular attention heading into winter.

Test it before you need it

A generator should be exercised regularly, not left to sit. Many standby units run a periodic self-test, but you should confirm yours is actually cycling and running properly. Testing before winter lets you catch a problem while it is a minor repair rather than a cold-night emergency. If your generator has not run in months, that is a signal to test it now.

Check your fuel supply

Fuel readiness depends on your generator type:

• Natural gas units draw from your gas line, so supply is generally continuous, but the connection and regulator should be confirmed in good order.
• Propane units rely on tank level, so make sure the tank is adequately filled before winter and monitor it during extended outages.
• Diesel and gasoline units need fresh, properly stored fuel, and stale fuel is a common cause of starting problems.

Knowing your fuel situation ahead of time prevents running dry partway through a storm.

Keep it clear and accessible

Winter weather can bury or block a generator. To keep it ready:

• Keep the area around the unit clear of snow and ice.
• Make sure exhaust and air intakes stay unobstructed, which is critical for safe operation.
• Keep the unit clear of drifting snow and falling ice from the roof.
• Never operate a generator in an enclosed space, since carbon monoxide is deadly.

Safe clearances and unobstructed exhaust are not just about performance, they are essential for preventing carbon monoxide hazards.

Confirm the transfer switch and connections

Your transfer switch is what safely connects the generator to your home and keeps it isolated from the utility. Confirm it is working and that your critical circuits are covered. If your needs have changed, such as wanting to power additional circuits, winter prep is a good time to discuss it with your electrician.

Winter generator readiness for a Maryland home comes down to service, testing, fuel, and clearance. Have the unit maintained, confirm the battery and transfer switch, test that it starts and runs, check your fuel supply for your generator type, and keep the unit clear of snow and ice with unobstructed exhaust. Doing this before the first winter storm means your generator will be ready when an ice storm or heavy snow takes the power down.
