Replace an existing system
Reuse sound infrastructure only after airflow, duct leakage and electrical checks.
WHOLE-HOME COOLING
Compare central AC as a complete installed project
Match the equipment to a documented load calculation, then compare duct, electrical, permit, commissioning, warranty and financing scope on the same basis.
Choose your route
Three ways to frame the project
Use the same home details and assumptions for every contractor so the proposals can be compared fairly.
New central-air project
Plan equipment, ducts, returns, drainage, controls and power as one coordinated system.
Repair or replace
Compare the repair, remaining life, comfort issues and future energy cost before deciding.
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.
- 01Heating and cooling load calculation
- 02Indoor and outdoor equipment
- 03Supply and return duct assessment
- 04Electrical circuit and disconnect
- 05Condensate management
- 06Permits, startup and commissioning
Cost drivers
Why local installed prices vary
- Home size and design conditions
- Duct repair or replacement
- Efficiency and equipment tier
- Panel or circuit upgrades
- Access, crane and permit needs
CoolCompare does not present a national sticker price as your project price. ZIP code, property conditions, code requirements and proposal scope must be evaluated together.
Ownership viewEnergy Maintenance Warranty 5/10 years
Compare 5- and 10-year cost
Compare modeled annual use with the same thermostat and weather assumptions.
Include filters, coil care and annual service.
Separate parts, labor and registration requirements.
Add installation, energy, maintenance, repairs and financing—not just equipment price.
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.
Quote checklist
Ask every bidder for the same six items
Comparable documentation makes price differences easier to understand and reduces hidden-scope surprises.
- 01AHRI-matched equipment reference
- 02Manual J load calculation
- 03Duct and airflow findings
- 04Itemized electrical and permit work
- 05Commissioning report
- 06Labor and parts warranty terms

US project questions
Answers to use before requesting bids
What should be included in a compare central ac as a complete installed project quote?+
The quote should identify the exact equipment or materials, installation scope, permits, electrical or fuel work, commissioning, exclusions, schedule, payment terms and separate labor and product warranties.
How should I compare central ac contractors?+
Give each contractor the same home details and ask for an itemized scope. Compare credentials, measurements, assumptions, cash price, financing, warranty and post-installation verification—not the headline price alone.
Can incentives reduce the project cost?+
Federal, state, Tribal, local and utility programs can differ by installation year, ZIP code, equipment tier, income and funding status. Verify eligibility with the official program administrator before signing or spending.
