These hidden passages can become filled with Dust, allergens, and microscopic particles that progressively Construct up out of sight. On the subject of preserving these systems, Experienced air duct cleaning is a crucial Portion of it.

The horizontal traces are for quantity stream price. The downward diagonal strains are for velocity, the upward diagonal traces are for duct diameter.

While ductless systems (usually often called mini-splits) and ducted air-source warmth pumps operate in the same way to air conditioners during the warmer months, it’s how they run throughout the colder months that sets them apart.
