Confirm the equipment pairing and electric territory
Folsom heat-pump planning starts with the electric account and exact property address. Use SMUD's territory lookup to confirm service before applying its residential incentives; a city name or ZIP code alone is not an eligibility decision.
For rooms that warm unevenly, compare duct delivery and thermostat behavior before increasing capacity. If a variable-speed system is proposed, ask how the indoor unit, outdoor unit and controls will work together at partial output.
For commercial split systems, bring matched systems and controls into the scope discussion. Ask whether a partial replacement is approved and practical for the existing equipment. Compare it with a complete matched option using serviceability and total scope, not only the cost of the failed component.
