• Scope of Work: Repair/replace/maintain; systems covered (split/packaged, heat pumps incl. cold-climate, gas furnace/boiler & hydronic, mini-split/VRF, RTUs; ERV/HRV; controls).
• Service Levels: Standard vs. emergency response; after-hours rates; snow/ice/freezing, wind, and smoke/air-quality rescheduling language.
• Pricing Model: Flat-rate vs. time-and-materials; trip fee policy; parts handling/mark-up.
• Materials & Parts: OEM vs. equivalent; high-altitude derating/orifice notes; low-ambient/defrost controls; condensate freeze protection; hail guards for exposed coils.
• Customer Responsibilities: Filters, clearances, utilities, HOA/roof access, keeping paths clear of snow/ice for safe work.
• Warranty: Labor window; manufacturer pass-through; exclusions (misuse, neglect, freeze/smoke/hail damage, corrosion, non-payment).
• Code & Safety: Local permits/inspections; IMC/IECC-based adoption with municipal amendments; EPA refrigerant rules; rooftop fall protection; combustion and makeup air at altitude.
• Change Orders: Written/e-signed authorization for hidden conditions and price changes.
• Payment Terms: Deposits/milestones; due-on-completion; late fees.

Idaho-Specific Notes (Read Before You Sign)

DBS licensing: Idaho HVAC work is regulated by the state’s Division of Building Safety (contractor and journeyman licensing). Display your legal business name and license number(s) on proposals and the contract; use properly licensed electrical/plumbing subs where applicable.

Permits & inspections are local/state-administered: Mechanical/gas permits are issued by the local AHJ or the state where the jurisdiction is under DBS (e.g., Boise, Meridian, Nampa, Idaho Falls, Pocatello, Coeur d’Alene, Twin Falls). Confirm permit needs, plan review, and inspection timing before change-outs or new installs.

Energy/mechanical codes: Cities/counties enforce IMC/IECC/IRC variants with amendments. If your scope triggers duct sealing/leakage testing, ventilation/HRV balancing, economizers on certain RTUs, or commissioning, reflect responsibilities and testing fees in the agreement.

Altitude, freezing & hail: Above ~5,000 ft, many gas appliances require derating and adjusted combustion air. Specify orifice/pressure adjustments, verification, and freeze protection for condensate and piping. Consider hail guards for exposed outdoor coils.

Wildfire smoke & AQ: Add language for poor air quality service limits, filter upgrades (MERV), and rescheduling where AQI is hazardous to work.

Cooling-off (in-home sales): For covered door-to-door/home solicitations, customers generally have a 3-business-day right to cancel. Attach the written notice when applicable.

Liens: Idaho recognizes mechanic’s lien rights with specific timelines. Keep clear payment terms and retain proof of required notices/waivers.
