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.

What you get

Everything in the plan.

  • Fall furnace tune-up

    Combustion test, heat exchanger inspection, flame sensor and cabinet cleaning, and a CO safety check before the first cold snap.

  • Spring AC tune-up

    Coil and cabinet cleaning, refrigerant check, capacitor and contactor test, and a drain flush.

  • Priority scheduling

    Members go to the front of the line on the days everyone else is calling.

    A flat percentage off every repair for as long as you’re a member.

  • No overtime fees

Good questions

Comfort Plans FAQ.

Is a maintenance plan really worth it?

A tuned system burns less, fails less, and lasts years longer. Between two tune-ups, repair discounts, and no overtime fees, most members come out ahead in the first year.

Do you service rental properties?

Yes. Landlords and property managers get one plan covering several addresses with a single point of contact.
