When AirGreen Saved a Daycare from the Heatwave with a Lightning-Fast Wall-Mounted AC Installation (Thrilling Story)

An urgent call, unbearable heat, children in thermal distress: it was in this scorching context that AirGreen demonstrated the full extent of its expertise in wall-mounted air conditioner installation. Thanks to a rapid, professional, and highly technical intervention, we helped a daycare in Montréal restore a healthy and comfortable indoor climate for its toddlers during a heatwave.

A Daycare in Distress in Montréal: A Case of Absolute Urgency

It was 8:00 AM when a daycare located in the Rosemont–La Petite-Patrie neighborhood of Montréal contacted us, completely overwhelmed by suffocating heat that had settled over the building for two days. Several portable AC units had failed, the windows didn’t allow proper ventilation, and the indoor temperature was nearing 32 °C, endangering the health and safety of the children.

At AirGreen, we know that facilities caring for children demand absolute responsiveness and precision. In under two hours, our technical team was on-site to assess the situation and propose a tailored solution.

Immediate Diagnosis and Ideal Equipment Choice

Given the urgency, our team lead recommended installing two Gree LOMO R-32 wall-mounted air conditioners, each with a capacity of 12,000 BTU. This choice was based on several factors:

  • High energy efficiency (SEER 21)

  • Use of R-32 refrigerant, environmentally friendly

  • Ultra-quiet operation, perfect for sensitive environments like a daycare

  • Quick installation without major construction

We also confirmed that these units were eligible for Hydro-Québec’s LogisVert Grant, information we immediately shared with the daycare's management.

A CVAC Installation Executed at Full Speed

The installation had to happen that same day, so we mobilized two AirGreen teams to complete the installation of the two wall-mounted units in under five hours. Thanks to our fully equipped fleet, our always-stocked local inventory in Montréal, and our experience handling high-pressure CVAC projects, everything was carried out with exemplary precision.

Key Steps in the Intervention:

  1. Thermal analysis of the space to confirm required BTU load

  2. Identification of optimal wall locations for even air distribution

  3. Installation of indoor units with reinforced mounting, high up and out of children's reach

  4. Drilling exterior walls dust-free and disruption-free, using our extraction systems

  5. Installation of outdoor units on anti-vibration wall brackets, discreet and secure

  6. Electrical connection through a dedicated box with thermal protection

  7. Complete system testing, air flow adjustment, remote setup

Immediate Results: Comfort Restored for the Children

By 4:00 PM, everything was up and running. The indoor temperature dropped from 32 °C to 23 °C in less than 90 minutes, providing immediate relief to the children, educators, and parents. The daycare director, visibly moved, said:

“We’ve never seen a team work this efficiently. Thanks to AirGreen, the children were able to nap peacefully that same afternoon.”

This project was a clear demonstration of our ability to act swiftly, even under critical conditions, while maintaining top-tier CVAC installation standards.
