HVAC Replacement: Installation Responsibilities to Review
Replacing a furnace, air conditioner or heat pump can involve electrical work, gas connections, venting, refrigerant handling and changes to ducts. Ask the proposed installer how the equipment will be sized, connected and checked at startup.
Permits and refrigerants
Michigan’s mechanical permit guidance describes permit requirements and exemptions. Confirm the requirements with the authority responsible for your property; do not assume every project has the same permit process.
EPA Section 608 certification requirements apply to technicians performing covered refrigerant work. Certification is a specific refrigerant-handling requirement, not a substitute for checking other licensing, permits or project responsibilities.

Warranty terms
Read the warranty for the actual proposed models. Installation, registration, ownership and service conditions can affect coverage. Ask separately about manufacturer parts coverage and the installer’s labor warranty. Do not assume every brand or purchasing channel provides identical terms.

Request model numbers, installation scope, required permits, startup checks, disposal and responsibility for follow-up service. A lower equipment-only price may exclude work included in an installed proposal.
