Understanding replacement estimates
Compare HVAC estimates. Then compare the price.
A useful replacement estimate explains the job you are agreeing to. Before comparing totals, check that the proposals describe the same equipment, installation work and responsibilities.
Ask about current availability.
Bring an existing estimate if you would like help comparing the equipment and installation scope.
The equipment and the space.
Ask for enough equipment detail to understand the recommendation. The proposal should relate to the building rather than simply repeat the size of the old unit.
- Identification
- What indoor and outdoor equipment is proposed? Which existing components and controls will remain?
- Selection
- How was the system's capacity determined for the property? Were the comfort concerns you described considered?
- Compatibility
- How do the proposed components, controls and existing installation work together?
The installation scope.
A short equipment list is not a complete description of installation. Ask what the price covers and what conditions could change the work or cost.
- Included work
- Clarify removal and disposal, installation, connections, controls, site protection and cleanup.
- Related work and exclusions
- Ask about any airflow, duct, electrical or access issues that may need separate work. Identify allowances and exclusions in writing.
- Permits and completion
- Confirm the applicable jurisdiction, any required permits and inspections, who handles them, and what startup or completion checks are included.
The terms after the total.
Review payment terms, scheduling arrangements and the process for approving changes. Ask which written equipment terms and parts-and-labor commitment apply to the work being proposed, and whether there are exclusions, registration steps or care conditions.
A short comparison you can use.
For each estimate, write down the proposed equipment, included work, excluded work, permit responsibility, payment terms and any written equipment or work terms. If an item is unclear, ask before assuming it is included. That conversation can be more useful than comparing totals that cover different jobs.
Get at least three estimates.
If you are considering a complete system replacement, we evaluate your existing system at no charge. We recommend getting at least three estimates so you can compare the equipment, installation scope and written terms.
Your questions
Questions, answered.
How can I tell whether two HVAC estimates cover the same job?
Compare the proposed model numbers, capacity, indoor and outdoor equipment, controls and installation work. Then check removal and disposal, ductwork, permits, inspections, startup checks and exclusions. A price comparison is meaningful only after you understand what each contractor is including.
What should I ask about parts-and-labor coverage?
We stand behind our work, including parts and labor. Ask the team to explain how that commitment applies to the proposed work and whether any separate equipment terms, exclusions or care conditions apply. Do not assume a product-related issue includes every cost involved in a future repair.
What if extra work is discovered during installation?
Before approving the job, clarify how changes are priced and authorized. Known ductwork, electrical or access issues should be identified in the proposal, along with allowances or exclusions. If the scope changes, understand the additional work and cost before authorizing it.
Is the evaluation free if I am considering a complete replacement?
If you are considering a complete system replacement, we evaluate your existing system at no charge. We recommend getting at least three estimates so you can compare the equipment, installation scope and written terms.
