(WHAS11) -- For the first time this season our temperatures are dropping down consistently into the 40s overnight and that means it could be time to turn up the heat.
Is your furnace tuned up and ready for the winter challenge?
The average family spends at least $2,000 on energy bills with half of that spent on heating. If your furnace isn't running efficiently those costs grow even higher. Depending on the age and energy efficiency of your furnace, it may even be cheaper to replace the furnace.
"The average life of a heating/cooling system is somewhere between 12-18 years so obviously as you get older things start to break down in your body, the same thing happens with heating and cooling equipment," HVAC contractor Kris Conover said.
There are warning signs your furnace may need replacing, and they include mounting utility bills. Furnaces lose efficiency as they get older, and if you're constantly adjusting the thermostat to make your home more comfortable it may be time to take the plunge.
Angie hicks from Angie’s List said it may even be time to double down.
"If you have the funds to also upgrade your air conditioner you can actually save some money because the installation crew is already on site. Also, manufacturers offer discounts when you bundle the two products," Hicks said.
Now may be an especially good time because there are tax credits for qualifying products that expire at the end of the year.
