Lowering energy bills, improving indoor comfort, and optimizing air quality—these are just a few of the major reasons why homeowners in Laval are turning to replace their outdated heating system with a multizone heat pump. At AirGreen, we carry out hundreds of HVAC system installations and replacements each year in homes and buildings of all sizes throughout Laval, the North Shore, and the Greater Montreal Area. Here are the 5 clear signs we frequently observe among our clients, indicating that it's time to upgrade to a modern multizone heat pump.
Heating and cooling bills are rising with no clear explanation
When your energy costs keep going up year after year, even though electricity rates remain fairly stable, it’s often a sign that your existing heating system is losing efficiency. An old electric furnace or aging heat pump has to work harder to maintain a comfortable temperature. That leads to excessive energy consumption and significant financial loss.
At AirGreen, we recently replaced a central system from 2005 in a home in Chomedey, Laval. The homeowner was spending around $3,200 per year on heating. After installing a Fujitsu KWL-BT multizone heat pump, their yearly costs dropped to about $1,700—nearly a 50% savings.
Uneven temperature across different rooms in the house
If your bathroom feels chilly, your bedroom is too hot, and the basement room is practically unusable in winter, these temperature imbalances are often due to an old central system that no longer suits your home's layout.
A multizone heat pump, equipped with multiple independent indoor units, allows you to set the temperature room by room, offering personalized comfort in each area. This system is especially popular in Laval, where many homes have been extended over the years, creating challenges for heat distribution. AirGreen recently installed a Gree Free Match multizone system in a home in Vimont, with four indoor units covering each floor and a garage converted into an office.
A noisy system, strange sounds, or equipment that runs constantly
A noisy heating system—clicking, humming, or seemingly always running—is a clear sign it’s nearing the end of its life. These symptoms often point to a worn-out compressor, unbalanced fans, or poor duct insulation.
One of our clients in Sainte-Dorothée contacted us after noticing their old unit wouldn’t stop running, even when it reached the desired temperature. We diagnosed a faulty central thermostat and an overused compressor. The solution: replace the entire system with a Bosch BOVA-60HDN1-M20G multizone heat pump, a high-efficiency inverter model. The results: remarkable quiet, better temperature control, and a 35% reduction in energy consumption.
Frequent repairs and hard-to-find replacement parts
If you're calling your HVAC technician several times a year, or each repair requires special-ordered, often costly parts, it's time to consider a full system replacement.
We recently assisted a homeowner in Laval-des-Rapides who had spent over $1,500 in repairs within just 18 months. The system in question was a central Goodman unit installed in 2007. We replaced it with a Gree Multi+ Ultra multizone heat pump, with four zones, including a wall-mounted programmable thermostat and an outdoor unit rated to operate in temperatures as low as -30°C. Not only were the issues resolved, but the client also received a $1,684 LogisVert rebate from Hydro-Québec.
A poorly insulated or newly renovated home that needs a more efficient solution
If you've recently renovated your home (an extension, a new floor, or a converted basement), or if your insulation isn’t up to par, your old central system may no longer be sufficient. A multizone heat pump offers precise adaptation to the heating and cooling needs of each room, even after major changes.
For example, in a duplex converted into a single-family home in Laval-sur-le-Lac, AirGreen installed a Daikin multizone system with 5 indoor units, including both wall-mounted and floor-mounted consoles, perfectly suited to varying ceiling heights and unique configurations. This type of setup enables smart energy management, with consistent comfort and improved overall efficiency.
