What Your Ohio HVAC Contract Should Include

The builder formats these into a clean, professional agreement:

• Parties & Premises: Legal names, service address, site contact, access windows; attic/roof/mech-room access if applicable.
• Scope of Work: Repair/replace/maintain; split/packaged, cold-climate heat pumps, gas furnace/boiler & hydronic, mini-split/VRF, RTUs/DOAS; ERV/HRV; controls/BAS.
• Service Levels: Standard vs. emergency; after-hours; snow/ice/freezing, severe thunderstorm/wind, and hail rescheduling language (especially rooftops).
• Pricing Model: Flat-rate vs. time-and-materials; trip fee; parts handling/mark-up.
• Materials & Parts: OEM or equivalent; low-ambient/defrost controls; condensate freeze protection & overflow safeties; curb adapters & hail/wind guards for RTUs; vibration isolation.
• Customer Responsibilities: Filters, clearances, utilities, HOA/condo approvals, roof/elevator access, snow/debris removal for safe access.
• Warranty: Labor window; manufacturer pass-through; exclusions (misuse, neglect, wind/hail/freeze/flood damage, non-payment).
• Code & Safety: Local permits/inspections; Ohio Mechanical & Energy Codes (IMC/IECC-based) with municipal amendments; EPA refrigerant rules; rooftop fall protection.
• Change Orders: Written/e-signed authorization for hidden conditions and price changes.
• Payment Terms: Deposits/milestones; due-on-completion; late fees.
• Termination: For convenience vs. cause; cure periods; demobilization costs.
• Dispute & Venue: Ohio law; optional county venue (Franklin, Cuyahoga, Hamilton, Lucas, Summit, Montgomery, Butler, Stark, Lorain, Mahoning, etc.).
• Licensing/Registration: Show your legal business name and the applicable license/registration numbers. OCILB issues state licenses for commercial HVAC, hydronics, refrigeration, and electrical; many municipalities also require contractor registration, especially for residential jobs.

Ohio-Specific Notes (Read Before You Sign)

Licensing: For commercial scopes, the Ohio Construction Industry Licensing Board (OCILB) licenses HVAC, hydronics, and refrigeration contractors. Residential scopes may require municipal registration. Display your legal company name and the relevant numbers on proposals and the contract; use properly licensed subs for electrical/plumbing/gas-fitting as required.

Permits & inspections: Issued by the local building department (e.g., Columbus, Cleveland, Cincinnati, Toledo, Akron, Dayton). Confirm permit needs, plan review (rooftop units/curb adapters/wind), fees, and inspection timing before change-outs or new installs.

Codes: Jurisdictions enforce Ohio Mechanical & Energy (IMC/IECC-based) with local amendments. If your scope triggers duct leakage tests, ventilation/ERV balancing, economizers/DOAS, or commissioning/controls, assign responsibilities and testing fees in the contract.

Weather & site conditions: Include freeze protection for condensate/piping, auxiliary pans/float switches for attic AHUs, anchorage and hail/wind guards for RTUs, and rescheduling language for snow/ice or severe thunderstorms.

Fuel-burning equipment: Where gas/oil appliances are involved, reference trade credentials and safety steps (leak checks, venting/make-up air, CO testing).

Cooling-off (in-home sales): Covered door-to-door/home solicitations generally include a 3-business-day right to cancel. Attach the written notice when applicable.

Liens: Ohio law provides mechanic’s lien rights with specific notices/timelines. Keep clear payment terms and retain proof of any required notices/waivers.
