Medical Emergency: How a Wall-Mounted Air Conditioner Helped a Medical Clinic Stay Operational During a Heatwave in Longueuil

A critical HVAC installation in the heart of summer: when air conditioning becomes a public health issue in Longueuil

During one of the hottest summers on record in Longueuil, a neighborhood medical clinic urgently reached out to AirGreen. Their aging central air conditioning system had broken down in the middle of a heatwave, putting elderly patients, children, and staff at serious risk. Thanks to a rapid response and the installation of a high-performance wall-mounted air conditioner, the clinic was able to continue offering essential care. This is the story of a project that perfectly illustrates our ability to handle critical HVAC situations with speed, precision, and expertise.

The situation: a medical clinic facing dangerous indoor heat

The building in question is a small general medical clinic located in a residential area of Longueuil. The central air conditioning system, over 18 years old, failed in the middle of July. With more than 40 patients visiting daily, long consultations, and multiple large windows facing south, indoor temperatures reached 34°C, creating unbearable working conditions and posing a serious threat to vulnerable patients.

The clinic's management needed a solution that was:

• Quick to install;

• Energy efficient;

• Quiet, to avoid disrupting consultations;

• Reliable and durable, to withstand daily intensive use.

Our solution: installation of a GREE LOMO+ 18,000 BTU wall-mounted air conditioner

After an on-site evaluation, we recommended the GREE LOMO+ 18,000 BTU, a wall-mounted air conditioner known for its durability, energy efficiency, and quiet operation.

Why this model?

• High-efficiency Inverter technology (SEER 21, HSPF 11) for optimized energy use;

• Ultra-quiet operation (as low as 20 dB on low speed), perfect for a medical setting;

• Adjustable directional airflow, so cool air doesn't blow directly on patients;

• Advanced air filtration, essential in a healthcare environment;

• Eligible for Hydro-Québec’s LogisVert rebate ($1,704 in this case).

Exact steps of the emergency HVAC installation

The intervention was scheduled in less than 24 hours. We deployed a team specialized in emergency HVAC installations in sensitive environments, equipped with everything needed.

On-site execution:

1. Safe removal of the broken system, with environmentally responsible refrigerant recovery;

2. Installation of the GREE LOMO+ wall-mounted air conditioner in the waiting room, positioned to cover the most critical areas;

3. Reinforced wall mounting with minimal drilling to preserve the building’s integrity;

4. Placement of the outdoor unit on a vibration-absorbing base, with weather and tamper protection;

5. Full system activation, including pressure testing, wall controller setup, and airflow adjustments.

The entire process was completed in just one day, without interrupting care thanks to precise planning.

The results: back to normal in under 24 hours

By the next day, temperatures inside the clinic were stabilized at 23.5°C, even during the heatwave. The medical staff immediately noticed the difference:

• Improved patient comfort, especially for children and the elderly;

• Normal resumption of consultations, with no delays or cancellations;

• Controlled electricity consumption, with an estimated 30% savings compared to the old system.

Challenges faced and how AirGreen responded

Working in an active medical environment requires a methodical approach. Here are some specific challenges we overcame:

• No power interruptions allowed: we used top-of-the-line cordless tools to avoid disrupting IT and medical equipment.

• Absolute cleanliness was mandatory: every drilling and installation phase followed strict cleaning protocols with HEPA vacuums and disinfecting wipes.

• Precise acoustic calibration: we activated night mode during patient rest periods to ensure minimal noise.

Why AirGreen is the ideal choice for sensitive environments

At AirGreen, we understand that every HVAC installation has unique demands. In a medical context, we adapt our methods, tools, and timelines to ensure flawless results.

Our commitments:

• Fast, well-planned interventions, even in emergencies;

• Certified technicians with experience in critical environment HVAC;

• Strict compliance with health and electrical standards;

• Full support with all available rebate programs.

We’ve successfully completed numerous HVAC installations in clinics, schools, offices, and homes across Longueuil, Montreal, Laval, Rive Nord, and Rive Sud.

AirGreen’s tips for clinics and healthcare facilities

If you manage a medical or institutional space, here’s our advice to prevent failures and maintain comfort for your users:

• Have your HVAC system inspected before the hot season begins;

• Consider a wall-mounted unit as a backup to the central system, in case of breakdown;

• Choose systems with HEPA or UV air filtration, ideal for sensitive environments;

• Schedule an annual preventive maintenance contract with a certified provider;

• Make sure your HVAC provider can intervene in under 24 hours if needed.

Conclusion: a wall-mounted air conditioner that delivers more than comfort

This project in Longueuil shows how a well-designed, well-executed, and quickly deployed HVAC installation can ensure continuity of care in a medical clinic. For AirGreen, it’s not just about cooling the air: it’s about protecting lives, comfort, and well-being.
