What Longueuil residents ask
Can a wall-mounted AC also heat?
Many wall units are heat pumps that cool in summer and heat in the shoulder seasons — efficient, year-round comfort.
How many indoor units do I need?
One outdoor unit can feed several heads. We assess your space to recommend the right configuration.
Can I replace my old furnace with a heat pump in Longueuil?
Often yes. A central heat pump uses your existing ducts and, paired with a backup source for deep cold (dual-energy), effectively replaces an aging furnace while cutting costs.
