As temperatures begin to drop, we spend more time indoors—and the risk of carbon monoxide exposure can increase. Every month, take a minute to test your carbon monoxide alarms and double check the expiration date on devices. If you use a portable generator during a power outage, remember that generators should only be operated outdoors in a well-ventilated area. A few simple precautions can help keep your family safe all winter long.

OFFICE CLOSURE

Our office will be closed on Monday, November 2nd, 10:30 a.m. - 12:30 p.m. as we take time to support one of our own while they say goodbye to their beloved mother-in-law.

Please join us in keeping their family in your thoughts and prayers during this difficult time.

Thank you for your understanding and support.

Our phones will be switched over to our 24/7 on-call service for any emergencies during this time.
