“I turned my heat on and it smells like something is burning.” This is a call we receive numerous times during our first “cold snap” here in Florida. Once you turn on your heat, it’s normal to smell burning dust. Dust settles on the heating components, but burns off as soon as the unit heats up. Open a window to dispel the odor quickly. If the smell lasts for more than a few hours, it’s probably time to change filters or sanitize your ducts. Apple Air conditioning offers low cost seasonal maintenances and annual service contracts that can save you money all year long.
