Tips for Starting a HVAC in Washington
1. Start the license process early
Washington hvac licenses can take 4-12 weeks to process. Apply BEFORE signing a lease — a denied license on a signed lease is the #1 start-up disaster.
2. Budget 20% contingency
In Washington, unexpected costs — construction delays, permit revisions, equipment installation — typically add 15-25% to planned start-up costs. Build this into your funding request upfront.
3. Negotiate your lease aggressively
At $30/sq ft median rent in Washington, negotiating just $2/sq ft off a 1,200 sq ft space saves $72000/year. Ask for: 3-6 months rent abatement during buildout, tenant improvement allowance, and a 5-year lease with 2 renewal options.
