Central Heat Pump Installation

A central heat pump connects to your existing ductwork the same way a furnace or central air conditioner does, giving whole-home heating and cooling through one thermostat. Chauffage Climatisation Gatineau installs central heat pumps for Gatineau and Hull homes that already have forced-air ducts, including setups that keep the existing furnace as backup heat.

Working with your existing ductwork

Central heat pumps move a different volume and temperature of air than a typical furnace, so duct sizing matters more than with some other equipment. Undersized returns or poorly sealed ducts can cause noise, uneven room temperatures, or reduced capacity. Before recommending a central system, we inspect ducts for size, sealing and insulation, and flag anything that should be addressed alongside the installation.

  • Full duct inspection before equipment selection
  • Compatible air handler or existing furnace blower
  • Single thermostat control for heating and cooling
  • Return air sizing checked against new equipment capacity

Pairing a heat pump with existing heating

A central heat pump can be paired with the heating already in the house, so it carries most of the season and the existing system covers the coldest hours. The term dual-fuel applies when that backup burns a fuel — natural gas, propane or oil — and the thermostat switches over below a set outdoor temperature. With an electric furnace or baseboards the backup is electric, which behaves similarly but is not dual-fuel. Which arrangement fits depends on the equipment already installed, and is confirmed at the assessment.

Replacing a central air conditioner with a heat pump

If you're due for a new central air conditioner, a central heat pump uses the same ductwork and often similar equipment footprint, while adding heating capability you didn't have before. It's worth considering at that replacement point rather than installing a straight AC and revisiting heating separately later.

How it works

  1. 01

    Ductwork and system assessment

    We check your existing ducts, furnace or air handler, and electrical service to confirm compatibility.

  2. 02

    Equipment and control plan

    We recommend equipment sized to your home and, where applicable, set up switchover to the backup heat already in place.

  3. 03

    Installation and commissioning

    The outdoor unit, coil and controls are installed and tested, with airflow verified across your existing duct system.

Frequently asked questions

Can I add a central heat pump to my current furnace?

In many cases yes: the heat pump handles most of the heating and the existing furnace takes over in very cold weather. That is called dual-fuel when the furnace burns gas, propane or oil; with an electric furnace the backup is electric instead. Compatibility depends on your furnace and ductwork.

Will my ducts need to be replaced?

Not always, but undersized or leaky ducts can limit a heat pump's performance more than they would a furnace, so we check duct condition before installation and recommend repairs if needed.

How is a central heat pump different from a wall-mounted one?

A central system uses your existing ductwork and one thermostat for the whole house, while wall-mounted systems condition individual rooms directly without ducts. The right choice depends on whether you already have functional ductwork.

Does a central heat pump replace my air conditioner?

Yes, a central heat pump provides both heating and cooling, so it replaces the function of a central air conditioner while adding heating capability.

What happens when it's too cold for the heat pump?

The system automatically switches to the backup heat below a set outdoor temperature, so the home keeps heating without you needing to intervene. That backup is the existing furnace in a dual-fuel setup, or electric heat where that is what the house has.
