Light commercial HVAC in Seattle.

We focus on light commercial work: tenant improvements, small offices (under 10,000 sq ft), retail buildouts, restaurants, and small medical/professional spaces. We're sized for jobs that need fast turn and tight permit coordination. Off-hours install on every occupied space. Dust containment, tenant communication, and daily progress reports are standard. Permits and inspections handled in-house, including DCI + L&I coordination.

What drives the price

Equipment class, TI scope, permits, occupied-space install.

  1. 01

    Equipment class

    Light commercial RTUs vs split systems vs VRF. We focus on the first two.

  2. 02

    TI scope

    Existing ductwork + electrical condition. Most TIs reuse, some need new runs.

  3. 03

    Permits + inspections

    Commercial work is more permit-heavy. We handle Seattle DCI + L&I coordination.

  4. 04

    Occupied space install

    Off-hours work, dust containment, tenant communication. We have a playbook.

Light commercial focus

We focus on light commercialtenant improvements, small office, retail, F&B.

We don't chase 100-ton rooftop jobs. We focus on light commercial: tenant improvements, small offices (under 10,000 sq ft), retail buildouts, restaurants, and small medical/professional spaces. We're sized for jobs that need fast turn and tight permit coordination.

Off-hours install on every occupied space. We work nights and weekends to avoid tenant disruption. Dust containment, tenant communication, and daily progress reports are standard.

Permits and inspections are heavier in commercial. We handle Seattle DCI + L&I coordination, mechanical permits, and energy compliance docs. That cost is in the quote, never billed separately.

Why homeowners pick us

Three operational choices that change how the install lands.

Real Manual J load calculations.

We don't quote from square footage. Every system is sized from a measured load calculation accounting for insulation, windows, orientation, and air sealing. Oversized equipment is the most common failure mode we see on competitor installs.

In-house electrical.

HVAC and electrical under one roof. No subcontractor coordination, no second permit, no surprise add-ons after the gas guy leaves. If your panel needs work, we do it with the same crew on the same week.

Final payment after walkthrough.

You sign off after we walk the install with you. Anything you flag, we fix. Your money clears only after you say it's right. That clause is in writing on every install.

Black Lotus might not currently have the marketing chops of the bigger outfits, it's worth giving them a meeting. We're glad we did. They charged us 1/2 of other bids I had gotten.
