Request ductless ac installation for a property in Richmond Hill. Include the equipment, the problem or planned work, and your location so the request can be reviewed.
What should be assessed before choosing locations for ductless mini-split units?
A ductless mini-split can be considered where a room or addition needs cooling and extending central ductwork is not suitable. Installation scope depends on the area to be served, indoor-unit locations, electrical capacity, outdoor-unit placement, and the route for refrigerant and condensate lines. If replacing an existing unit, inspection should establish whether the problem calls for repair or a new system and whether existing penetrations and connections can be reused.
Measure the areas to be served and note room use, window exposure, ceiling and wall construction, and existing cooling equipment. Confirm electrical capacity, drainage options, line routing, and suitable indoor and outdoor mounting locations. These details affect equipment selection and installation work. If a unit already exists, its model, fault history, and the condition of lines and openings help determine whether repair or replacement fits the request.

Assessment and Scope
Questions for the Proposed Work
01
Match equipment and indoor-unit locations to the space
Room dimensions alone do not establish the right system. The assessment should consider how connected spaces communicate, where occupants need cooling, and whether an indoor head can deliver air without obstruction. Electrical capacity and the proposed outdoor-unit location also shape the available options. A written installation scope should identify the areas served, equipment configuration, and any construction or electrical work that affects placement.
02
Plan line routing, drainage, and existing openings
Refrigerant lines, wiring, and condensate drainage need a practical route between each indoor head and the outdoor unit. Where an existing opening is being reused, inspect its size, condition, and location rather than assuming it suits new equipment. A slow drain or musty odor from an existing head may call for diagnosis and cleaning before replacement. Line covers, mounting supports, and condensate pumps should be included only when the site requires them.
03
Distinguish a replacement from a new installation
A like-for-like replacement may be simpler where the equipment arrangement and connections are compatible, but existing penetrations do not guarantee that a new model fits. Confirm refrigerant compatibility, electrical requirements, line condition, controls, and mounting locations. If the current unit has a suspected fault, diagnosis may show that repair is the narrower scope. A new installation instead requires planning the served rooms, equipment locations, and line routes from the outset.
Compare the next step
Agree on the rooms and seasons assigned to the new ductless system and the equipment that remains. Ask how settings avoid competing heating and cooling calls. Record the supported controls and maintenance responsibilities for each system so occupants understand which appliance to use for a particular comfort need.
