Extreme coldHeat pumps in Châteauguay
Heat pump, heating and air conditioning sales, installation and service in Châteauguay and the surrounding area, by Groupe Moïse, a Salaberry-de-Valleyfield family business since 1976.

The right solution for your home
Châteauguay’s bungalows and two-storey homes heated with baseboards are a great fit for a wall unit in the open living area, or a multi-zone system for the upstairs bedrooms. If the house has a furnace, a central heat pump can connect to it and keep the furnace as backup.
Every project starts with a site visit and a load calculation: we recommend the right size, not the biggest one, and work out your grant.

Wall, multi-zone and central heat pumps, furnaces, boilers, Steffes storage heaters.
