When an old Ruud system shows signs of fatigue
At AirGreen , we regularly work on central HVAC systems installed several years ago, particularly in single-family residences on the West Shore of Montreal . This was the case during a recent service call in Pointe-Claire , where a customer contacted us following a problem with loss of heating efficiency on a Ruud central heat pump .
The owner, aware of the value of his equipment, wanted to explore the possibility of a complete repair before considering replacement. Our team therefore undertook a detailed inspection to assess the overall condition of the system and identify the exact cause of the malfunction.
Initial inspection: complete diagnosis of the Ruud system
The Ruud heat pump in question, a robust design typical of the 2000s, provided both heating and cooling for the home. Despite its age, the unit remained mechanically sound, but several signs indicated a lack of thermal performance :
-
blowing warm air instead of hot air in heating mode;
-
irregular noise coming from the compressor;
-
frequent start-up cycles without maintaining a stable temperature.
Upon our arrival, our technicians carried out a series of electrical and refrigeration tests to determine the cause of this drop in efficiency. Pressure and electrical current measurements quickly revealed a problem with refrigerant charge loss due to a micro-leak in the outdoor condenser .
Intervention: detection and sealing of the leak
Once the source of the problem was located, our specialists began replacing the defective section of copper tubing , followed by a nitrogen leak test . This process ensures that the circuit is perfectly sealed before any refrigerant recharge.
After validation, we evacuated the system using a professional vacuum pump, removing any traces of moisture or air from the lines. The system was then recharged with R-410A refrigerant according to the exact specifications of the manufacturer Ruud.
Electrical checks and cleaning of the condenser
When carrying out repairs on a device of this type, it is essential to carry out complete preventive maintenance . We therefore have:
-
cleaned the condenser fins to improve air circulation;
-
tightened the electrical connections ;
-
checked the compressor start capacitor ;
-
and measured the resistance of the contactors to prevent future failure.
This type of proactive intervention significantly extends the lifespan of an already old appliance and helps maximize its energy efficiency.
Recommissioning and performance testing
Once the refrigeration circuit was restored, we restarted the Ruud heat pump . The results were immediate:
The system reached its nominal pressure , and the customer was able to observe a constant blowing of hot air from the first minutes of operation.
Our performance tests confirmed:
-
an optimal temperature difference between the intake air and the blown air;
-
stable electricity consumption ;
-
and a uniform ambient temperature throughout the ground floor.
Advice given to the customer: optimizing the lifespan of the system
Before concluding the intervention, we provided the owner with several maintenance recommendations to maximize the longevity of his Ruud equipment:
-
Clean the interior filters every two months to promote air circulation.
-
Schedule a complete annual inspection by an AirGreen technician, especially before winter.
-
Maintain outdoor condenser clearance to avoid air restriction caused by leaves, dust, or snow.
-
Consider, in the medium term, an energy upgrade to a high-efficiency model compatible with Chauffez Vert subsidies .
Result: restored comfort and customer satisfaction
At the end of the repair, the Ruud heat pump was operating smoothly and quietly, once again providing the expected thermal comfort throughout the house. The client, impressed by the thoroughness of the diagnosis and the speed of the repair, chose to subscribe to our AirGreen annual maintenance plan to prevent any future breakdowns.
This repair once again demonstrates our expertise in restoring central HVAC systems — whether recent or older — throughout the Greater Montreal region, Laval, Longueuil, and the North Shore .
