How to Save Your Central Heating After a Flood: A Real Story from the North Shore

Successful Rescue of a Central Heating System After a Major Flood

A flood can quickly turn everything it touches into a nightmare, especially central heating systems, which are often located in the basements of Quebec homes. At AirGreen, we recently encountered a critical situation in Rosemère, on the North Shore, where one of our clients urgently contacted us after rapid flooding caused by torrential rain. The quick and methodical intervention of our team fully salvaged their central heating system, avoiding significant replacement costs.

Context of a Climate Emergency on the North Shore

In Rosemère, exceptional rainfall last spring led to a sudden and unexpected rise in water levels. The affected home had a central heating system with a Lennox MMD electric furnace, 4-ton model, recently installed by our team. Due to the furnace's basement location, it was submerged under nearly 50 centimetres of water in just a few hours. The family's anxiety was intense, as they feared the permanent loss of their equipment.

Critical First Steps After the Flood

In this delicate situation, our intervention had to be swift and extremely precise. Upon arrival at the scene, just hours after the call, our priority was ensuring electrical safety and assessing damage to the heating system.

Here are the immediate steps taken by our expert team:

• Safe shutdown of the heating system to eliminate electrical hazards.

• Quick and complete removal of residual water from the affected area.

• Thorough evaluation of the Lennox MMD furnace's condition to determine whether it was recoverable or if a full replacement was necessary.

Technical Rescue of the Central Heating: AirGreen's Expert Approach

Thanks to our experience and deep understanding of Lennox systems, we established a detailed rescue plan. It consisted of several critical steps carried out methodically:

1. Complete drying of internal components:
   Our team carefully dismantled the furnace panels to accelerate drying of internal components such as the blower motor, electrical relays, and sensitive electronic boards.

2. Thorough inspection of sensitive parts:
   Each component was rigorously tested to detect any signs of corrosion or electrical damage. Irrecoverable or potentially dangerous parts were immediately replaced with original Lennox parts to ensure long-term reliability.

3. Complete sanitization of the ductwork system:
   Besides the furnace itself, the flooding introduced potential contaminants into the hot-air ducts. Professional sanitization of the ductwork was performed to prevent health risks and ensure healthy indoor air quality.

4. Progressive restart and rigorous control:
   After meticulous reassembly, we gradually restarted the system while closely monitoring its operation. This crucial step ensures optimal, safe, and durable performance of the heating system.

Technical Challenge and Innovative Solution by AirGreen

One major challenge during this operation was saving the blower motor, initially considered irretrievable. Thanks to our technical expertise and commitment to providing an economical and durable solution for our client, we managed to restore this critical component using specialized drying methods and an exclusive anti-corrosion treatment. Result: significant savings and rapid restoration of heating service for our client.

Final Result: Savings, Safety, and Restored Comfort

The final outcome exceeded the client's initial expectations. Not only was the Lennox MMD 4-ton central heating system fully restored, but it now operates with efficiency comparable to pre-flood conditions, preventing an unexpected investment of several thousand dollars. The family's relief and swift return to comfort was the ultimate reward for AirGreen’s team.
