Three ways to frame the project
Use the same home details and assumptions for every contractor so the proposals can be compared fairly.
Professional control upgrade
Best for multi-stage, communicating, zoned or heat-pump systems.
Utility-connected program
Compare rebates and demand-response terms before enrollment.
Installed scope
What a complete proposal should address
Not every item creates extra work, but every contractor should state whether it is included, excluded or not applicable.
- 01System and wiring identification
- 02Compatibility check
- 03Common-wire or adapter work
- 04Equipment staging and lockouts
- 05App, account and privacy setup

Built for US homes
Your ZIP code changes the comparison.
Climate, utility rates, fuel availability, building codes, permit offices and incentive administrators vary across the United States. A national average is only an orientation point.
Heating and cooling loads, humidity control and equipment performance must match the home’s actual climate.
Use current electricity and fuel prices, rate structure and any demand-response or electrification program terms.
Ask who obtains permits, schedules inspections and documents required electrical, mechanical or structural work.
Check the installation year, ZIP code, system tier, income rules, funding status and official reservation process.
