What we do

Residential and commercial, from installation to troubleshooting.

Wall-mounted heat pump installed in a living room with exposed wood beams

Wall-Mounted Heat Pump

Single-zone or multi-zone, up to five heads on a single outdoor unit. The most requested service, and the one where placement makes all the difference.

Commercial rooftop unit open for maintenance, filters removed and technician's tools nearby

Maintenance and Repair

Preventive visits and troubleshooting for all brands. A dirty coil costs money long before it breaks.

Central Heat Pump

Flexx from 2 to 5 tons, dual-fuel compatible with a gas furnace.

Air Conditioning

Cool a room, a floor, or an entire building, depending on the configuration.

Rooftop Unit

Installation, maintenance, and replacement on commercial roofs.

Air Treatment

Fresh air, humidity, and filtration: what the heat pump alone doesn’t fix.

Natural Gas Appliances

Furnaces, water heaters, and hookups by a licensed contractor.

The real range of the units

From -30°C to +30°C,
the same unit

A modern heat pump heats in winter and cools in summer. The Airy, Clivia, Freematch, and Flexx series maintain heating down to -30°C. The Charmo series stops at -25°C.

Southern and central Quebec have fewer than fifteen days per winter below -20°C. The rest of the season, the unit handles the load on its own. The backup system is only for peak periods.

A dirty coil drives up the bill before breaking the unit

Street dust, pollen, range hood grease. The layer builds up between the fins, heat exchange degrades, discharge pressure rises, and the compressor works longer for the same result. Nobody sees it coming.

The LogisVert Grant, Precisely Calculated

The amount is calculated based on the heating capacity at -8 °C, not the appliance’s nominal power. Most contractors write “up to $6,700.” We cross-reference the appliance’s AHRI number with Hydro-Québec’s official list and enter the exact amount in the quote.

Scale verified in August 2026. The program is evolving: consult Hydro-Québec’s official page.

$50 per 1,000 BTU/h increment at -8 °C — ENERGY STAR certified appliance

$120 per 1,000 BTU/h increment at -8 °C — cold climate type appliance

Indoor air quality

A heat pump does not refresh the air

It recycles the air in the room; it doesn’t bring in fresh air. In a well-insulated house, humidity and CO₂ rise, leading to foggy windows and stuffy mornings. Health Canada recommends maintaining relative humidity between 30 and 50%.

The Clivia series is the only wall-mounted unit in the range to offer a fresh air kit. It treats the room it’s in, not the whole building: it doesn’t replace an air exchanger.

Frequently Asked Questions

Yes. The Airy, Clivia, Freematch, and Flexx series heat down to -30°C, and the Charmo series down to -25°C. Southern and central Quebec have fewer than fifteen days per winter below -20°C: the rest of the time, the heat pump handles the load. A backup system takes over during extreme cold peaks.

$250 plus tax for a daytime call, which includes one hour of labor and travel. Beyond that, it’s $120 per hour. An emergency call between 4 PM and 7 AM is $600, including two hours of labor and one hour of travel.

The labor warranty is one year. The manufacturer’s warranty covers the compressor and parts for 10 years, extended to 12 years when the unit is registered with proof of installation. We handle the registration ourselves.

Not in existing buildings. The regulations adopted or under study in Quebec apply to new constructions. In Montreal, a regulation is in effect for new builds. The one for the Communauté métropolitaine de Montréal, which covers Laval, was still awaiting ministerial approval in spring 2026.

A residential wall-mounted installation is usually completed within the day. A central system or a multi-zone project takes longer, depending on the condition of the ductwork and access to the locations.

Since November 26, 2025, ENERGY STAR certification is a requirement for the LogisVert program. No Charmo models are certified, nor is the 24,000 BTU/h Airy. For this capacity, the lost aid significantly exceeds the price difference with an eligible unit.
