Installing a heat pump requires more than a device and a day of labor. Between the choice of model, the preparation of the home and the connection of the refrigeration circuit, a heat pump installation follows precise rules. Here is what this type of project actually covers in a house in Laval or the northern suburbs.
Wall or central, two different sites
The most useful distinction for a homeowner is the method of heat distribution. A wall-mounted, or split, heat pump combines an outdoor unit with one or more indoor units attached to the wall and first heats the rooms where they are located. The central heat pump is attached to the network of ducts and serves the entire home, which assumes a house already equipped with a forced air system.
Both belong to the air-air family and draw their energy from the outside air. Before find a heat pump in Laval adapted to your situation, have the surface to be heated, the quality of the insulation and the layout of the rooms assessed: these parameters weigh much more than the power announced on the technical sheet.
From site preparation to commissioning
The outdoor unit requires a stable base, sufficient clearance for air circulation and a position protected from snow accumulation, a very real constraint in Greater Montreal. Inside, the location chosen must allow the flow of condensates and the passage of the refrigeration lines towards the exterior wall. The route of these pipes should be stopped before the first drilling, because it determines the appearance of the wall as much as the performance of the system. The capacity of the electrical panel matters just as much, since the device requires a dedicated circuit.
The site then follows a fairly constant order. The supports are fixed, the wall drilled to provide passage for the pipes, then the two units connected. Next comes the vacuuming of the circuit, which expels humidity and air before charging with refrigerant and starting up. A simple wall-mounted system is usually set up within a day, while a central or multi-zone installation takes the team longer.
An authorized installer, initial condition
This work falls within a regulated framework. The company installing your device must hold a valid license in the refrigeration subcategory, supplemented by the electricity subcategory when the connection requires it. A public register allows you to check this status before signing the contract, a quick check that protects your guarantees and your insurance coverage.
The handling of the refrigerant is subject to its own requirements, since the technician must hold recognized environmental certification. The accreditations issued by the manufacturers complete this base and often condition the maintenance of the guarantee.
Financing, finally, meets comparable conditions. The subsidies still offered in Quebec for high-performance heat pumps require a device that is among the approved models and an application submitted within the expected time frame after the work. An installer experienced in these procedures will prevent you from losing the benefits.
