Frost on the lawn is one thing. Frozen pipes are another. 🥶

With colder nights making an appearance, now is a good time to give your plumbing a little attention before winter settles in. Pipes tucked into colder parts of your home can be easy to overlook until a faucet stops flowing.

Our frozen pipe prevention guide explains which areas deserve a closer look, how to help protect your plumbing, and the warning signs to watch for when temperatures drop.

The leaves are changing, the mornings are chilly, and someone in the house has officially been appointed head of thermostat security. 🍂

“It’s too early for the heat.”
“Put another sweatshirt on.”
“Grab a blanket.”

Meanwhile, someone’s bundled up on the couch, waiting for the thermostat guardian to leave the room so they can make their move.

What finally ends the debate in your house: a certain temperature, a certain date, or one very determined family member?

We’re going to add a few more things to your fall checklist. Somewhere between the apple picking, pumpkin decorating, and finding your favorite sweatshirt, your heating system deserves a little attention, too. 🍂

Fall weekends fill up fast, and an unexpected heating problem probably isn’t how you want to spend yours. Give your system a little attention now so there’s time to address any concerns between all the fun you’ve already penciled in.

What’s on your fall home checklist?

Fully charged? Time to unplug.
It is easy to leave a phone, laptop, tablet, or other rechargeable device connected long after the battery reaches 100 percent. However, leaving it plugged in longer than needed can create additional heat and place extra stress on its lithium-ion battery.

Try to charge devices while you are awake and nearby. Once charging is complete, unplug the device instead of leaving it connected overnight or while no one is home. This also gives you the chance to notice if the charger or device becomes unusually warm.

Before Fire Prevention Week comes to an end, take a look at your everyday charging habits. One small change, like unplugging when the battery is full, can become an easy part of your regular routine.
Safe charging is a superpower. Small action. Big impact.

Your rechargeable devices can give you warning signs when something is wrong. Knowing what to look for can help you act before the problem becomes more serious.
Stop using a device right away if its battery feels unusually warm, smells strange, makes popping or hissing noises, changes shape or color, begins to swell, leaks, or produces smoke. These can all be signs that the lithium-ion battery is damaged or failing.

If it is safe to do so, unplug the device and move it away from anything that can catch fire. Do not continue using or charging it to see if the problem goes away. If the device begins smoking or catches fire, move away from the area and call 911.

Phones, laptops, toys, and other devices can be replaced. Your safety cannot. Pay attention when a battery tells you something is not right.

A blocked drain can put your day on hold, but getting help shouldn’t add to the headache!

From an easy scheduling experience to helpful appointment updates, this homeowner felt supported before Darius even arrived. Once there, Darius got the drain flowing again and shared recommendations to help prevent future issues.

That’s the kind of experience we want our customers to remember: clear communication, helpful people and one less thing to worry about.

Thank you for choosing Haller and giving Darius a well deserved shoutout! ⭐

Today's Fire Prevention Week tip is all about where you charge your devices.
Charging your phone next to you on the couch or leaving a tablet plugged in on the bed may seem harmless, but soft surfaces are not safe places to charge rechargeable devices.

Phones, laptops, tablets, gaming devices, and their chargers produce heat while charging. Beds, couches, pillows, blankets, and other soft surfaces can trap that heat and block airflow around the device. That can cause the battery to overheat and increase the risk of fire.

Instead, place your device on a hard, flat surface such as a table, desk, counter, or floor while it charges. Keep it uncovered and give it plenty of room for air to circulate.
It only takes a few seconds to choose a safer charging spot. Small action. Big impact.
