We still need practical routes for refrigerant piping, electrical connections and drainage. We assess the rooms and finishes together, so improving comfort does not leave the effect on your home as an afterthought. ## Start with the existing building, not its age An older home may have usable ducts, unsuitable ducts or no distribution system serving the room you care about. Age alone does not establish which condition you have. We review the actual equipment and layout before deciding whether dedicated room equipment is appropriate. Tell us what stays uncomfortable and when. If you are renovating, explain the planned changes to windows, insulation and room use. We want the load assessment to match the intended home, rather than size for conditions that will soon change. ## Dedicated zones can avoid substantial duct construction Where no suitable ducts serve the space, a wall head may provide a direct room solution. Several enclosed rooms can need multiple units or another designed arrangement. We do not assume a large living-room head distributes air into bedrooms with their doors closed. A concealed-duct mini-split is another option where space allows it, but it still needs ducts and a return path. We explain that construction rather than describe every mini-split as ductless. The configuration should fit the building and the way you use the rooms. ## Trace the routes before settling the appearance A preferred indoor wall must connect to an outdoor location and suitable drain. We review possible penetrations, visible line covers and any openings in finished construction. A route that hides piping may involve more work than a direct exterior connection. The scope should identify responsibility for finish repairs. Preserving interior details is easier to discuss while route choices remain open. We aim to limit unnecessary disruption without promising that every installation avoids opening any surface. ## Historic requirements are parcel-specific If your property has applicable preservation requirements, we identify them in the project discussion. The adopted West Adams Terrace plan addresses visible mechanical equipment and less invasive attachment for affected properties. It is not a universal rule for all older Los Angeles homes. A building’s appearance or a historic survey mention alone does not establish its current designation. We need the actual parcel and applicable requirements. Less visible equipment still needs airflow and service access; preservation and practical installation must be considered together. ## Existing electrical equipment needs assessment We compare the selected system’s requirements with the property’s supply. A spare breaker position does not establish available capacity. The proposal should distinguish the mini-split circuit from panel or service work and identify further investigation where needed. Existing heating also needs accurate identification. Electric resistance baseboards, hot-water radiators and gas furnaces use different arrangements. An air-to-air mini-split does not connect refrigerant lines to hot-water heating pipes. We define what remains, what is removed and how separate equipment will be used. ## Drainage should be planned for a finished home Cooling creates water at the indoor coil. We look for a suitable gravity route and discuss a pump where the layout requires it. Its sound and maintenance access can matter in a quiet bedroom or concealed position. The chosen route should remain maintainable after furniture and finishes are in place. Hiding a pump or drain component behind permanent construction can make later access difficult. We explain the access provisions before the installation is agreed. ## Define a complete retrofit scope We bring the room loads, equipment choice and routes into the proposal, with electrical work, permits and verification responsibilities identified. Conditional incentives should stay separate from the installed cost. At handoff, we explain the controls, filters and project records so you can use and look after the new system.

[Get an Installation Estimate](#shared-estimate) ## Your project questions ### Does an old house automatically need a larger unit? No. The actual windows, insulation, leakage, layout and local conditions establish the load. Age is context, not a capacity calculation. ### Can we keep existing heat? Possibly. We identify the equipment and intended operation, then define what remains or is removed as part of the agreed scope. ### Can all piping be hidden? That depends on the building and routes. We explain openings, drainage and maintenance access before treating a concealed route as feasible.
