HORSEHEADS, N.Y. (WENY) -- Temperatures may not be expected to stay as cold as they'll get Friday night, but the first freeze of the season is a good reminder to prepare for the harsh winter months. 

"We're bringing in our rock salt and snow shovels and winter products to get ready for the winter," says Max Bernhard, Sales Associate at the Horseheads Do-it Center.

Employees spent time Friday afternoon stocking the Do-it Center in Horseheads with salt bags, wood pellets, heaters and more. While the harsh weather is still a ways away, the first freeze of does require some prioritizing. 

"Any fragile flowers or anything like that bring them inside. If they're planted cover them probably either with plastic or blankets or something just to insulate them for the night, and see where well go from there," Bernhard says. 

Another recommendation for this time of year is to check your furnace filter and igniters to make sure you're getting the right fuel flow. There are a variety of filters you can use," too. 

"It depends on your unit. Some units can take a standard fiber glass filter which is flat and then there's other ones that can take pleated, which are anywhere from Merv 6, Merv 8, Merv 10 and then a high allergen filtration system," Bernhard explains. 

Along with checking batteries on your smoke detectors, it's suggested to check all alarms. 

Get your CO2 detectors checked for the winter. Make sure their batteries are up -- they're within the reason of 'born-on' dates within 8 years if they're the old style. 10 years sealed battery units are out now by law," says Bernhard. 

On the subject of the furnace filter options, 'MERV' stands for Minimum Efficiency Reporting Value which was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers. Levels can range between 1 to 16, with the higher numbers reflecting a greater ability to effectively filter more particles in the air.
