HVAC Project Cost is a free, independent resource built for U.S. homeowners who are researching HVAC replacement costs. The site was created by Eric Moore to solve a simple problem: homeowners deserve to know what HVAC replacement actually costs before a contractor shows up to give a sales pitch.

Who This Site Is For
This site is built for homeowners who are facing a significant home expense and want to understand the cost landscape before committing. Whether you are replacing a failing AC unit, upgrading to a heat pump, or budgeting for a full HVAC system replacement, our free cost estimator and research guides are designed to help you make informed decisions.
Our Editorial Approach
Every cost range on this site is built from publicly available industry data and cross-referenced against multiple independent sources — not from contractor partnerships, affiliate deals, or lead-generation platforms. We explain exactly how every number is calculated, and our editorial policy is published for anyone to review.
Our core editorial commitment: estimator results are never gated behind an email address, phone number, or account registration. You enter your details, you get your estimate. That is the entire transaction. We believe that gating pricing information behind a contact form serves the contractor, not the homeowner. Our goal is to give you the pricing context you need to have productive conversations with contractors, understand what is fair in your market, and avoid overpaying for a system that does not match your actual needs. When you walk into a contractor meeting with a realistic cost range in hand, the dynamic changes in your favor.
How Cost Ranges Stay Current
HVAC pricing shifts over time as labor markets, equipment costs, and regional economies change. Our cost data is reviewed regularly and updated when source data indicates a material change. See our full Data Sources list for details on each source. Every update is versioned and documented. For the full technical explanation of how calculations work, see our Methodology page.
What This Site Is NOT
- Not a contractor. We do not install, repair, or service HVAC equipment. We provide pricing information only.
- Not a marketplace. We do not connect homeowners with contractors or receive referral fees from service providers.
- Not a lead-generation operation. We do not collect your information to sell to contractors. Your estimator results are yours — we do not share them with anyone.
