FAQs
Why is my top floor hot and my garden level cold?
Many multi-story homes experience a vertical “chimney effect.” We design multi-zone strategies to balance floors so the whole home performs consistently.
Can you add air purification for allergies and pets?
Yes—whole-home purification strategies can be integrated, including HEPA and UV-C options depending on system type and goals.
