Start with the distinction below, then define the deliverables and boundaries. If something is unknown, ask the provider to assess it.
Duct replacement · the key conversation
Identify accessible runs, insulation, registers and testing.
What to ask for in return
A written description of duct replacement, the assumptions behind the price and which items need further assessment. Ask the provider to explain equipment model numbers, sizing assessment, duct and electrical scope, commissioning record in the context of your request.
| Detail | Get this in writing | Keep the comparison fair |
|---|---|---|
| Equipment schedule | List the outdoor unit, indoor unit, controls and backup heat by model. | Compare the complete matched combination. |
| Distribution and connections | Identify ducts, electrical work, refrigerant lines, drainage and any fuel or venting work. | Show retained, replaced and excluded items. |
| Site preparation | State equipment location, access, removal, supports and surface repairs. | Confirm who handles each trade and permit. |
| Startup and support | Describe commissioning, balancing, warranty documents and follow-up. | Compare deliverables as well as warranty duration. |
UNDERSTAND THE PRICE
See the parts. Then compare the total.
A useful budget explains what the money covers. Keep these cost areas visible rather than relying on a package name or headline figure.

What changes the scope?
Compare the proposed system and the installation together. Equipment model numbers alone do not explain sizing, duct changes, electrical work or commissioning.
Ask providers to explain how equipment model numbers and sizing assessment affect their assumptions. Separate confirmed information from items still awaiting assessment.
What does the chart show?
The planning tool compares amounts you enter over the same period. Fixed charges, rate × quantity, monthly charges and extras stay separate. Its cumulative-cost graph makes different upfront and recurring arrangements easier to understand.
Published references, where available below, show their own units, source and period. They remain separate from your calculator inputs. Employee wages and producer-price indexes are context, not the price a provider will charge. Ask for current proposals for your actual scope.

A provider’s charge also covers costs such as nonbillable time, supervision, vehicles, equipment, insurance, administration and profit. The selected occupation may cover only part of a multitrade project. OEWS does not measure self-employed contractors’ fees. No wage-to-quote multiplier is applied, and these snapshots do not establish a current labor-price trend.

Agree any visit or diagnostic fee. Ask what must be checked before the price can be final.

Complete
Approve changes in writing and collect the agreed completion records.
A planning sequence, not a promised duration. Actual timing depends on the service, the information available and the provider's agreed scope.
WHEN YOU WANT THE DEEPER VIEW
The details worth resolving early.
Start with the comfort problem: rooms that never feel right, humidity, noise, repeated repairs or high running costs. A replacement should address the house and its air distribution as well as the equipment. Ask each installer to explain the proposed design before you compare model numbers.
For this particular project
Request a drawing or clearly described list of the runs, returns, registers and insulation included. Clarify access limitations and whether ceilings or finishes must be opened. Ask what testing or balancing is included and how excluded ducts affect the result. Compare the actual network being replaced rather than a single whole-house price.

- 02Check loads
- 03Specify system
- 04Install & test
- 05Review comfort
Replace one component or the complete system?
Ask which indoor and outdoor components remain, how the combination is matched, and who warrants the resulting installation. A quote for an outdoor unit alone can differ substantially from a complete system with an air handler, controls and duct changes. Put the retained components in writing.
Ducted, ductless or a combination?
Ducted equipment uses an air-distribution network. Ductless systems use indoor units serving defined spaces. Ask for the rooms served, proposed indoor-unit locations, line routing, condensate drainage and control strategy. A room-by-room plan is more useful than assuming that every room needs the same equipment.
What is the sizing based on?
Ask for the heating and cooling load assessment and the assumptions about insulation, windows, air leakage and planned renovations. The old unit’s size or floor area alone should not end the conversation. Ask how airflow, duct condition and backup heat affect the proposed system.
What will prove the installation is complete?
Request a commissioning record appropriate to the equipment: startup checks, measured settings, control setup and any required balancing or testing. Ask who registers the equipment, explains filters and maintenance, and handles a comfort complaint after startup. Separate product coverage from installation labor coverage.
What changes with location and conditions?
- Cold-weather performance and backup heat need a location-specific discussion. Ask for the equipment’s performance at the design conditions used by the installer.
- Hot or humid locations make moisture control and air distribution part of the comfort conversation. Ask how the proposed controls address both.
- Local electricity and fuel tariffs affect operating costs. Compare estimates using your rates and usage assumptions; an efficiency label alone does not predict your bill.
Documents to collect at completion
- Equipment model and serial numbers
- Startup and commissioning record
- Warranty and registration documents
- Filter, controls and maintenance instructions
Compare these promised records before choosing a provider. Keep the originals alongside your planning pack.

GOOD QUESTIONS, CLEARER CHOICES
Before you choose.
What should I include in a duct replacement request?
Identify accessible runs, insulation, registers and testing. Include equipment model numbers, sizing assessment, duct and electrical scope, commissioning record where known. Leave unknowns for the professional to assess.
Can I compare prices before an assessment?
You can compare the stated assumptions, scope and fee basis. Ask what must be checked before an offer is final and whether a consultation, inspection or diagnostic visit has a separate charge. For this service, start by clarifying equipment model numbers.
How should I handle a lower price?
Ask which tasks, deliverables and terms differ. Use the cost tool to compare the same period and quantities, then review exclusions and professional fit. The smallest calculated number is not a recommendation.
Does the planning pack create an agreement?
No. It records your brief and entered scenarios. You still need to review and agree the provider’s actual proposal and terms. Keep original documents and approvals.
What happens after I continue to my request?
Your reviewed brief enters the existing PickYourPro.ai request process. You will need an account and can confirm the remaining details before completing the request. Provider participation and availability vary.
Are these live market prices?
The planning calculator uses your entered figures. Published references elsewhere on the page are separate, dated observations with their own sources and limitations. Neither is a live provider quote. Employee wages are not billable labor rates, and a producer-price index is not an installed project price.
