Who we are

Hello. We’re Duality.

Duality Heating and Air LLC is a Denver heating and cooling company run by one licensed technician and the people he trusts. We fix furnaces, ACs, heat pumps, and the air in your home, and we do it the way we’d want it done at our own house. Comfort, in perfect balance.

  • Denver-based

    One technician who lives here, not a call center in another state.

  • Price in writing

    You approve the number before we touch a tool. It never changes.

  • Fix before replace

    We repair what can be repaired and show you both numbers when it can’t.
