Stop rebuilding the same spreadsheet
The free tools cover the quick decisions. The Pro toolkit is the stuff I built for my own crew over 25 years — estimating templates, curb cheat-sheets, and permit playbooks — cleaned up so you can put them to work tomorrow.
RTU Swap Estimating Template
The full estimate workbook: equipment, curb/adapter, crane and rigging, electrical, structural allowance, permit, and labor — with the markup logic baked in so nothing falls through the cracks.

Curb Adapter Cheat-Sheet
A laminated-ready field reference: the dimensional decision rules, the duct and penetration checklist, and the exact info a fabricator needs to build the adapter right the first time.

Permit-by-Jurisdiction Guide
The mid-Atlantic permit playbook: who pulls it, who inspects it, energy-code triggers, and the exact questions to ask each AHJ — organized by county so you're not guessing at bid time.

Refrigerant scale & recovery
A proper charging scale and recovery machine pays for itself fast on commercial work. Don't guess a charge on a new unit.
View options →Anemometer / airflow meter
Verify CFM at the diffusers after a swap. The number on the data plate isn't the number in the building until you measure it.
Check price →Rooftop safety & fall protection
Harness, anchor, and a roof warning-line kit. Non-negotiable on a commercial roof. Spend the money.
