MOUNT PLEASANT, SC (WCSC) - If you see lights, or hear banging noises coming from your heater, there's no reason to worry. Your heater is working hard to keep you warm.
Frank Allen, general manager of Olde Towne Heating and Air in Mount Pleasant said, "What I always tell my customers is whatever you're comfortable with."
Allen says there is no magic number for setting your thermostat in the winter.
"If you're comfortable with 68 degrees, then I'd say set it at 68 degrees," said Allen.
Some may have a different approach, but Allen says heating, ventilation and air condition systems in our region usually don't have a hard time keeping your home warm until the temperature dips below 42 degrees.
"What they'll [heating system] do is they'll bring on electric heat to help out at that time and with those thermostats, that's when you are going to see those lights coming on and going off again. It's just trying to maintain the temperature."
Allen says there's usually no need to worry when the light on your thermostat comes on.
"If those lights are coming on and off and we're above 42 degrees then there may be a problem with the system," said Allen.
Allen says one of the best things you can do for your heating system is to change your air filter every 30 days. He says a good way to remember is to just do it whenever you pay your utility bill.
Allen says when it's bitterly cold; your system will also fight frost on your unit outside.
"That's where you hear the loud noise and the swishing and the banging. That's actually the system shutting down, the fan motor rushing hot gas outside to take care of that," said Allen.
Heating systems do a lot more than some may realize, so it's important to take care of them to keep warm during every cold snap.
Allen also says you should have your system inspected twice a year so it's ready under extreme temperatures.
He also says homeowners should be sure to clear any debris around outside units.
