Comparing HVAC replacement proposals
Canonical HVACentric knowledge for all questions on this topic.
DIRECT ANSWER
Compare proposals against the same written scope: load calculation, equipment and matched components, efficiency, airflow and duct work, electrical or fuel work, controls, permits, removal, startup, commissioning, warranties, schedule, and exclusions. Model numbers and price alone do not show whether the installation scope is equivalent. Ask each contractor to clarify missing or assumed items in writing.
