Answering your frequently asked questions

FAQ

  • What HVAC repair and other services does J&J Climatisation offer in Laval and Montreal?

    J&J Climatisation provides full HVAC solutions for both residential and commercial properties in the Greater Montreal area, including Laval and the North Shore.

    Our services include installation, repair, and maintenance of heat pumps (cold-climate, multi-zone, and ducted systems), central air conditioning, pool heaters, walk-in coolers and freezers, and ventilation systems (ductwork, air exchangers).

    We also offer emergency repairs, regular servicing plans, and system upgrades to improve efficiency and comfort.

  • How do I know if my heat pump or AC system needs servicing or repair?

    Common warning signs include: 

    • Reduced heating or cooling performance 
    • Unusual noises or vibration
    • Frequent cycling (turning on and off)
    • Ice formation on outdoor units
    • Uneven temperature across rooms
    • Rising energy bills without increased usage.

    Our certified technicians perform diagnostics, checking refrigerant levels, electrical systems, air flow, and component integrity, to pinpoint the issue and provide you a transparent repair plan.

  • Do heat pumps really work during harsh Quebec winters?

    Yes, modern cold-climate heat pumps are specifically engineered to operate efficiently at low temperatures. Many models continue to extract heat even when outside temperatures reach −25 °C or colder. In extreme cold, a supplementary heating source may assist. Proper system sizing, insulation, and quality installation are critical to ensure reliable performance in winter conditions.

    Hydro-Québec’s subsidies and energy tips confirm that efficient heat pumps can reduce heating costs significantly and work year-round as both heating and cooling systems. 

  • How often should I maintain my HVAC or heat pump system?

    It’s recommended to schedule a professional inspection and servicing at least once per year, ideally in spring for cooling, and in fall for heating.

    A maintenance visit typically includes:

    • Cleaning coils and filters
    • Inspecting electrical components
    • Checking refrigerant pressures
    • Testing safety controls
    • Ensuring optimal airflow

    Doing so helps extend equipment life, maintain peak efficiency, and avoid costly breakdowns. 

  • What financial incentives or rebates are available for heat pumps in Quebec?

    There are several incentive programs available:

    • Hydro-Québec’s LogisVert program offers financial assistance for the purchase and installation of high-efficiency heat pumps (up to about CAD $6,700) under certain conditions. 
    • The Oil to Heat Pump Affordability (OHPA) program from the federal government can provide an upfront payment up to $10,000 for homeowners switching from oil heating to heat pumps. 
    • The Chauffez Vert program offers incentives for replacing oil or propane systems with electric or renewable energy systems (valid only until March 31, 2026). 

    Eligibility depends on system efficiency, contractor qualifications, timeline, and other conditions.


  • What is the expected lifespan of a heat pump or HVAC system, and how can I maximize it?

    A high-quality heat pump or HVAC system can last 15 to 20 years (sometimes longer) if properly installed and maintained. To maximize lifespan:

    • Schedule annual professional maintenance
    • Keep air filters clean (replace every 1–3 months)
    • Ensure outdoor units are clear of debris, snow, or ice
    • Avoid frequent on/off cycling by using proper system sizing
    • Address small repairs early to prevent bigger failures

    Routine care and proactive maintenance help protect your investment, maintain energy efficiency, and reduce unexpected repair costs.
