What should a West Kelowna homeowner confirm before AC installation?

Start with the home's actual cooling problem and the equipment already in place. Record the rooms that overheat, when the problem appears, existing furnace or air handler information, ducted or ductless layout, thermostat location, filter size, electrical panel location, and any recent renovation. Photograph accessible equipment nameplates and the proposed outdoor-unit area from safe ground-level locations. These notes help a contractor assess the property, but they do not establish the correct system size or prove that an existing duct system can support a new unit.

Describe constraints that can change the installation: strata or landlord approval, narrow access, hillside or retaining conditions, bedroom noise concerns, drainage, snow or vegetation, roof or wall penetrations, and the need to protect finishes. Ask each bidder to identify what was observed, what still needs an on-site assessment, and which assumptions affect the quote. Keep air conditioning, heat-pump, electrical, building, and any gas or ventilation work as separate scope lines when they are not the same project.

• List rooms, comfort symptoms, existing equipment, access limits, and the preferred control location.
• Photograph nameplates, panel and service equipment, ducts, condensate routes, and the proposed outdoor-unit area.
• Ask for a written distinction between confirmed conditions, design assumptions, allowances, and exclusions.

The City of West Kelowna says permits are required for most projects on private property and that owners or their authorized contractor or agent are responsible for obtaining required building permits before work begins. Its building-permit material includes alteration work and asks for a detailed scope. An AC installation can involve more than equipment placement if it changes walls, openings, structural support, heating or ventilation systems, drainage, or other building components. Describe the complete project to the City rather than relying on a generic statement that an AC unit is minor work.

Electrical and refrigeration requirements are separate questions. Technical Safety BC identifies heat pumps as regulated refrigeration equipment and separately addresses the electrical work required for installation. Its homeowner electrical permit guidance specifically lists connecting permanently installed equipment such as a heat pump as work that often requires a permit, while a hired licensed contractor applies on the homeowner's behalf. For a conventional AC project, ask the responsible contractor to identify the current permit route for the exact equipment and electrical scope, and retain the permit number or documented basis for any exemption.

• Ask West Kelowna how the complete alteration, equipment, penetration, drainage, and structural scope should be classified.
• Put City permit responsibility and Technical Safety BC electrical or refrigeration responsibility in the contract.
• Do not treat an application receipt, quote statement, or permit exemption claim as an issued approval without the authority's current record.

Compare the proposed result and the work boundary, not only the equipment brand or total price. Each quote should identify the system type, capacity assumptions, indoor and outdoor equipment, controls, duct changes or indoor heads, refrigerant line set, electrical disconnect and circuit boundary, condensate management, supports, penetrations, weather sealing, protection, disposal, startup, and cleanup. Ask the contractor to explain the assessment behind the capacity recommendation and to label any item that depends on a site visit, load calculation, existing duct inspection, or electrical review.

A useful quote also states what happens when the existing home differs from the proposal. Require written treatment of undersized or damaged ducts, inaccessible wiring, inadequate panel capacity, condensate routing, wall or roof repairs, equipment clearances, noise concerns, and concealed damage. If the project is a heat pump rather than cooling-only AC, make heating operation, defrost, controls, backup heat, and the separate regulatory path explicit. Do not turn a sales estimate into an unsupported promise about whole-home comfort, energy savings, noise, lifespan, or operating cost.

• Compare capacity assumptions, equipment, controls, line sets, ducts, wiring, drainage, supports, and restoration line by line.
• Require allowances and change-order rules for concealed conditions or electrical and duct modifications.
• Ask what will be measured, tested, commissioned, and handed over at startup.

Before installation, confirm who will coordinate the City and Technical Safety BC steps, who requests inspections or assessments, and which work must remain visible. Keep the signed scope, equipment model and serial information, permit records, inspection outcomes, photos of concealed work, electrical information, condensate details, and approved changes together. A final invoice does not by itself show that required approvals, tests, or declarations were completed.

At startup, ask for the operating and maintenance information that applies to the installed system. This can include thermostat or control settings, filter dimensions, access panels, drain and condensate precautions, outdoor-unit clearance and cleaning instructions, service contacts, warranty documents, and the contractor's startup or test record. If the system cannot be started safely or a deficiency remains, record it as open work with an owner and next action. Use the maintenance checklist for recurring care, but do not substitute it for a safety inspection or repair diagnosis.

• Retain permits, inspection or assessment outcomes, model information, photos, startup data, and approved changes.
• Get written operating, filter, drain, outdoor-unit, warranty, and service instructions at handoff.
• List incomplete, excluded, or owner-supplied work separately from the installed and commissioned scope.
