Whether you use your AC every day or almost never, simply switch your AC to heat and let it blow a few moments. This will dust off the heating coils. If you notice a bit of a "burning dust" smell, that's okay. Anything greater than that, including smoke, will need an inspection.
It is better to call us out now, before you need us on a chilly night or with a house full of guests.
