While newer systems should handle the temperature changes better, the frequent on-and-off cycling can still cause problems."When it flings - going from hot to cold - so, normally on a newer system there should be nothing wrong with it. The constant off and on can cause a problem - speaking heating wise or your heating element or your gas furnace," Ruiz said.Older systems face more significant challenges. The constant temperature changes can lead to burned-out elements and failed motors. Repairs can range from a few hundred dollars to the cost of an entirely new system.Older units may also be harder to fix, with parts that are tougher to find and less efficient over time."To make sure everything is operating for when the temperature does switch like that - make sure everything is in coordinates. Make sure there is no element that's popped. Make sure the cooling is working," Ruiz said.Ruiz also warns that skipping maintenance can mean missing damage caused by unwelcome guests.
