A calmer way to buy HVAC

Turn three contractor bids into one comparable decision.

A low quote is not automatically a good quote. Compare load assumptions, equipment efficiency, included electrical work, permit scope, warranty, and commissioning—not just the total.

Compare written proposals
  1. 01
    Size the project

    Estimate capacity and challenge oversized proposals.

  2. 02
    Model ownership cost

    Compare purchase price with annual energy cost.

  3. 03
    Verify the scope

    Confirm permits, electrical work, controls, and commissioning.
