NASHVILLE, Tenn.-The cold weather prompts changes to both the inside and outside of homes. Furnaces will be firing up for the first time, and patchy frost could threaten plants.
Saturday night, John Anderson and his wife flipped the switch on their thermostat to heat instead of cool, but when they did, nothing happened in part of the house.
"The frontiersman has come out, and me and the wife and I are hunkered down in the one warm area, but we look forward to getting the rest of the area up and running," said Anderson.
With temperatures expected to dip into the 30's for the first time this fall, many homeowners are getting annual maintenance on their heating units.
"If they're not having preventative maintenance done, a lot of times your pressure switch tube port will get blocked with rust or debris, and we'll need to clean those out. Also the flame sensors get dirty, and those need to be cleaned," said Dan Glaves with Hiller Heating and Cooling.
In both cases the furnace won't operate properly, and the homeowner could be left out in the cold. Heat is just one of the issues homeowners will face as the temperature drops; safety is another other reason to keep the heating unit up-to-date. A leak could release carbon monoxide or even start a fire.
Scattered areas of frost are predicted outside of Nashville as well. That means it's time to bring those tropical plants that sit on the patio inside, but a local nursery owner says before bringing them in, spray them down with insecticide.
"The danger you run when you bring plants in from the outside, is the things that you bring with them. Those are things such as scale, or mealy bugs, or other pest problems that can affect your plants inside that are totally clean," said David Bates.
