New installations & complete replacements

Complete commercial HVAC system replacement.

A complete system replacement is a planned capital project, not a repair visit. Air Zone takes replacement inquiries from owners, property managers and facility teams who are ready to retire existing heating and cooling equipment.

What counts as a full system replacement?

A full replacement removes the existing heating, cooling or air-handling equipment and installs new equipment with the connections, controls and duct changes the new system needs. If the current system only needs a part or a service visit, a repair contractor is the right call. Air Zone handles complete replacements.

Gather what you know about the existing equipment

List the equipment types, approximate ages, model numbers and the areas each system serves. Note recurring comfort complaints, equipment that has already failed and any planned renovations. Photographs of nameplates and mechanical rooms help explain the project.

Decide what the replacement should change

Tell Air Zone whether you want like-for-like equipment or a different approach, such as new zoning, a heat pump, or consolidating several units. Ask each proposal to explain how the equipment was selected for the building rather than matched to the old nameplate alone.

Plan the work around tenants and operations

Describe operating hours, occupied areas and spaces that cannot lose heating or cooling. Ask whether the work can be phased, what temporary conditions to expect, and who communicates with tenants. Schedule depends on the actual building and equipment availability.

Request a comparable written scope

Ask for exact models, removal and disposal, duct and control changes, electrical and fuel work, rigging or crane access, permits and inspections, and handover documentation. Compare scopes line by line before comparing totals.
