What is already in the house?
Write down the current heating fuel, furnace model, cooling equipment, and any rooms that are uncomfortable. If you have ducts, ask whether they are suitable for the proposed system. If you do not, discuss ductless heat pumps or the work involved in adding ducts.
How will the house be heated in winter?
Ask for the proposed heat pump’s heating capacity at the outdoor conditions used to design the system for your home. Ask whether supplemental heating is included, when it runs, and how the controls switch between sources. Cold-climate equipment exists, but the model and installation design still matter.

Can a furnace stay with a heat pump?
A heat pump can be combined with a gas furnace in a dual-fuel system. That does not mean every existing furnace can stay. Ask which components are compatible, what controls are required, and whether the proposal includes retaining or replacing the furnace.

Compare options that cover the same work
A heating-only furnace quote is not the same scope as a heat pump quote that also replaces cooling. Ask each proposal to identify the rooms served, heating and cooling equipment, controls, duct changes, electrical work, removal, and any required permits. Have each contractor identify what remains from the old system.
Keep installation cost separate from running cost
Request the installed price and the assumptions behind any operating-cost estimate separately. Provide your current fuel and electricity bills rather than relying on a generic savings percentage. Ask whether the estimate includes supplemental heat. Confirm any incentive directly with its administrator before treating it as a reduction in the project price.
Bring your priorities to the first conversation
Tell Air Zone what needs replacing, whether cooling is part of the project, your property location, and your preferred timing. Mention equipment you hope to keep and any planned renovations. Air Zone must confirm project fit and availability before you make installation plans.
General planning information. Equipment selection, price, scheduling, and project scope need to be confirmed for your property.
