HEATING & COOLING · HIRING GUIDE
How to compare heating and cooling replacement proposals
A useful replacement proposal explains the equipment, the work around it and the assumptions for your home. Compare those details before you compare totals.
Heating and cooling systems are not interchangeable boxes. A proposal may involve the existing equipment, ductwork, electrical work, controls, drainage and the layout of the home. Ask each contractor to explain the information they used and which parts of the job are included.
Ask what the contractor evaluated
Tell each company about the rooms you use, comfort concerns, energy history you want to discuss and relevant changes to the home. The Department of Energy describes heat pumps as equipment that transfers heat and notes that system type and operation vary. Source: Department of Energy heat-pump systems overview.
Do not select a system from a headline efficiency number alone. Ask the contractor to explain how the proposed equipment fits the home, climate and existing distribution system.
Compare the written scope
- What equipment, controls and related work are included?
- What existing equipment will be removed, and who handles disposal?
- Are duct, electrical, drainage or structural changes included or excluded?
- What site work, permits or inspections does the contractor expect?
- What happens if a condition changes the scope after work starts?
The FTC says written estimates should describe the work, materials, completion date and price. It advises asking why estimates differ instead of choosing automatically on the total. Source: FTC contractor guidance.
Keep incentives and operating costs out of the sales shortcut
Equipment availability, local rules, energy use and any utility offer can change. Ask for the exact product information and verify current details with the relevant manufacturer, utility or local authority. A contractor’s proposal should not be treated as a promise of a particular bill, approval or incentive.
Ask for the proposed installation schedule, disruption to occupied rooms and the plan for removing old equipment. If electrical or duct changes are proposed, have the company say whether those are included, estimated separately or subject to a later inspection. This helps reveal two proposals that are not pricing the same job.
Before signing, read the agreement for the exact equipment, start assumptions, payment stages and process for changes. Check local contractor requirements independently. The aim is a clear project record, not a prediction that a particular product will produce a fixed comfort or energy result.
Question: Why can two heating and cooling replacement proposals recommend different systems?
Answer: The contractors may use different assumptions about the home, existing equipment, distribution, comfort needs or work included. Ask each company to name those assumptions in writing, then compare the full scope.
When you are ready to compare proposals, start a heating and cooling request. PickedPros is a matching service. Contractors provide their own proposals, and you decide whether to hire.
