A heat pump should be serviced at least once a year, ideally before the heating or cooling season.

Annual maintenance allows you to clean the filters, check the refrigerant level, inspect the electrical connections, and ensure that all components are working properly. For commercial systems or those used intensively, maintenance every six months is recommended.

Installing a standard residential air conditioning system typically takes 4 to 8 hours for a wall-mounted unit, and 1 to 3 days for a complete central system.

The duration depends on several factors: the type of system chosen, the configuration of your building, access to workspaces, and whether modifications to the electrical system or structure are necessary. For commercial projects, the duration may vary.

A noticeable increase in dust in your space, persistent or unusual odors, increased indoor humidity, unusual noises coming from the unit, or a rise in your energy bills for no apparent reason.

If you notice excessive condensation on your windows, increased allergies among occupants, or that your system seems to be running constantly without maintaining the desired comfort level, professional cleaning is required.

An air exchanger should be cleaned at least every two years, and more frequently in dusty environments or homes with pets.

Yes, modern heat pumps operate efficiently even during Quebec’s harsh winters. Recent models, designed for northern climates, can extract heat from the outside air even at temperatures as low as -25°C to -30°C.

Replacement becomes more cost-effective than repair when your system is over 15 years old, repair costs exceed 50% of the price of a new unit, or you have to make frequent repairs every year.

Other indicators include a steady increase in your energy bills despite regular maintenance, the system’s inability to maintain a comfortable temperature, or if your unit uses R-22 refrigerant, which is no longer manufactured.

Noises coming from a ventilation system can have several causes. A whistling sound usually indicates an airflow problem, often caused by dirty filters or clogged ducts. Clicking or clattering noises suggest loose components, poorly secured ducts, or debris in the fan.

A squeaking noise may indicate that the motor is lacking lubrication or that the bearings are worn. A constant humming noise could indicate an electrical problem or a faulty motor.

If the noise appears suddenly or gradually intensifies, a professional inspection is required quickly to prevent further damage. A well-maintained ventilation system operates quietly and should never produce unusual or disturbing noises.
