Musty smell when the heat pump switches to heating

The first heating days sometimes bring a musty startup smell. Dirt and moisture on accessible coils and pans are a common cleaning path.

Questions about this service

Is the smell mould?

Appearance or smell alone may not identify a substance. Climeo cleans accessible dirt and residue; specialized assessment may be needed for building contamination.
