Plan heating around the building and site
For an El Dorado Hills heat-pump proposal, record the existing fuel, number of zones and any difficulty maintaining heat during colder conditions. Capacity retention and minimum operating temperature are different specifications and should not be treated as interchangeable.
Where multiple systems serve the property, ask for a separate evaluation of each. Replacing one unit should include its actual indoor pairing and controls rather than assuming every system should be sized or configured alike.
For packaged units, bring multi-system heating performance into the scope discussion. Compare the existing fuel arrangement with suitable replacement choices. If a heat-pump conversion is considered, evaluate electrical requirements and the approved equipment configuration before relying on a rebate.
