We don't ask for all the money up front. Fresh Air uses milestone billing. You pay in steps tied to work done. This keeps the project clear and fair for you.
Home size is the first cost driver. A 1,500 sq ft home needs a smaller unit than a 2,800 sq ft home. Unit brand and efficiency level also matter. High-efficiency units cost more up front but save on bills over time. SMUD rebates may apply, so check current amounts at smud.org.
