Louisville / HVAC installation
For a Louisville replacement, decide whether you are changing the air conditioner, the furnace or both. Ask each bidder how the new equipment will work with anything retained, what happens to the ducts and which permit applies. Compare proposals on scope, not just total price.
Local homeowner guide / Reviewed October 10, 2026
A furnace-only, AC-only or combined replacement are different projects with different prices. Write down which you want quoted and ask every bidder to quote the same boundary. If a bidder recommends changing the boundary, ask for the reason in writing.
When one half of a split system stays, ask how the new equipment will be matched to it and whether the indoor coil, blower or controls are affected. Ask whether the existing ductwork was evaluated and whether any changes are included in the price.
Ask whether the project requires a permit in your jurisdiction and who obtains it. Confirm that removal and disposal of the old equipment are included. Keep the Kentucky license reference, the permit details and the final scope together with the signed agreement.

It depends on the age and condition of each unit and how well they will work together. Ask bidders to explain both options in writing rather than accepting a single recommendation without reasons.
Compare the written scope line by line: equipment, ductwork, controls, permit, removal and warranty terms. A lower total that leaves out work can cost more later.
