PLANNING / SELECTION / HANDOVER
Before choosing the equipment
Compare the retained furnace condition with the cost and scope of a matched replacement. Ask how changeover settings account for equipment capacity, local rates and comfort priorities.
What belongs in the quote
Require the control sequence in plain language and confirmation of equipment compatibility. Handover should include the chosen settings and a demonstration of both heating modes.
Think about the surrounding system
Ask for the proposed equipment combination, its capacity at your design outdoor temperature and a written backup-heat strategy. Compare electrical work, distribution changes, condensate handling and controls alongside the outdoor unit. A brand name alone does not describe the complete system.
Three questions for your contractor
- What determines the changeover point?
- Is the existing furnace compatible?
- Who verifies both operating modes?
Prepare a useful first conversation
Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.
This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
