01
Score my home comfort
Screen six risks from ZIP and home facts.
02Check my HVAC quote
Screen price, scope, warranty and financing.
03Repair or replace?
Compare age, repair burden and replacement context.
04Find incentives
Verify current state, utility and local routes.
05Estimate replacement cost
Start with a broad ZIP-adjusted planning band.
Every major home system
One decision platform.
Start with the home and the project. Compare compatible equipment, installation scope, operating cost, incentives, financing and warranty together.

CoolCompare Project Planner
Turn your home into a quote-ready brief.
Organize your home facts and project needs. Choose an equipment path for a broad budget screen, then carry the brief into written quote, energy and ownership comparisons.
A better comparison model
Price is only one line in the proposal.
A low equipment price can hide incomplete electrical work, undersized duct changes, short labor warranties or expensive financing.
Scope
Normalize labor, permits, electrical, ductwork, disposal and commissioning.
Own
Model energy, maintenance, financing and likely repairs over 5 and 10 years.
Select
Compare eligible local contractors on price, scope, credentials and warranty when matching coverage is available.
