A service call for healthier air at home
At AirGreen , we know that a good ventilation system is not a luxury, but a necessity to maintain a healthy indoor environment, especially during Quebec winters when homes remain closed for long months. It is in this context that a customer from Boisbriand , on the North Shore of Montreal , contacted us about a problem with his LifeBreath air exchanger , a device essential to the air quality of his home.
Symptoms reported by the client
The customer told us that his air exchanger had not been working properly for several days:
-
The incoming airflow seemed reduced .
-
A persistent smell of damp began to be felt in some rooms.
-
The engine seemed to run intermittently , without producing constant ventilation.
These symptoms indicated a potential mechanical or electrical problem—a typical situation after several years of continuous use without regular maintenance.
On-site technical diagnosis
Upon arrival, we inspected the LifeBreath unit installed in the client's basement . The model in question was a LifeBreath 155MAX , a heat recovery air exchanger widely used in single-family homes.
After cutting the power supply , our technicians carried out a complete disassembly of the front panel to assess:
-
The condition of the motor and the dual-flow fan .
-
The cleanliness of the filters and the heat exchange core .
-
Internal electrical connections .
-
Ventilation ducts and static airflow .
The result: a significant buildup of dust and condensation clogged the heat exchanger core. In addition, a loose wire on the control panel prevented the motor from restarting properly after each cycle.
Repair intervention
The intervention was carried out in three precise stages:
1. Complete cleaning of the exchange core
We removed and washed the polypropylene core , then cleaned the internal compartment to remove any light mold caused by stagnant condensation. This cleaning significantly improves heat transfer efficiency.
2. Repair of electrical wiring
We then tightened the faulty connection on the electronic control panel , checking the output voltages of the motor and transformer. After testing, circuit continuity was restored and the fan started up normally again.
3. Checking and balancing the air flow
Using a professional anemometer , we adjusted the flow rate to achieve a perfect balance between incoming and outgoing air. This adjustment ensures stable internal pressure and prevents moisture from seeping into the walls.
Result: optimal ventilation and a satisfied customer
Once the repair was completed, the LifeBreath returned to peak performance. Final measurements showed a balanced airflow of 85 CFM , ideal for the size of the home.
The customer immediately noticed an improvement in air quality and the disappearance of the damp smell. We also advised him to add annual maintenance to his schedule to prevent dust from accumulating in the heat exchanger core again.
The importance of preventive maintenance of an air exchanger
Our technicians often point out that the air exchanger is an often-overlooked, yet crucial, device. Without regular cleaning, it can:
-
Reduce energy efficiency by up to 40% .
-
Promote mold growth in ducts.
-
Cause unpleasant odors and allergies .
We recommend cleaning the filters every three months and having the system checked once a year by an AirGreen certified technician.
