In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.

  2. The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.

  3. A shut-off switch near the outdoor unit isolates it safely for service.

  4. Sitting on the indoor module, it moves heat between the house air and the refrigerant.

  5. Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.

  6. Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.

  7. It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.

  8. It runs the heat pump and the backup heat. It must be compatible with the installed system.

Expert Air Handler & Electric Furnace Repair in Île-Bizard–Sainte-Geneviève

When it comes to HVAC systems, reliability and performance are essential, especially in a climate like ours in Montréal. We at AirGreen understand that sometimes these systems need a bit of professional care to keep running smoothly. Recently, we were called to a home in Île-Bizard–Sainte-Geneviève for a repair service on a York Air Handler and Electric Furnace, part of a central HVAC system that was experiencing electronic issues.

The Challenge: An Intermittent Furnace and Central AC Malfunction

The homeowner noticed inconsistent behavior with their HVAC system. Sometimes, the furnace simply wouldn't start, leaving the home cold during chilly spells. Other times, it seemed to overcompensate, running non-stop and failing to regulate the temperature properly. To make matters worse, the central AC component was also affected, occasionally refusing to kick in when needed. This inconsistency was causing significant discomfort and left the homeowner in a dilemma, unsure whether the system needed a simple fix or a full replacement.

The issues hinted at a possible electronic component failure, a common problem in older HVAC systems where wiring, sensors, or relays can degrade over time. Our goal was to diagnose the exact cause, repair it, and restore the system’s performance without suggesting a costly replacement, if avoidable.

Diagnosis and Solution: Precision Repair of a York Central System

Upon arrival, our team of certified HVAC technicians conducted a thorough inspection of the York Air Handler and Electric Furnace. We approached the repair with our usual methodical process, checking each component for continuity and stability to ensure we accurately pinpointed the problem. Given that this was a York system—a brand known for durability and efficiency when maintained correctly—there was a good chance we could extend its lifespan with targeted repairs.

Identifying the Faulty Electronic Component

Through our testing, we discovered the root cause: an intermittent fault in one of the furnace’s electronic modules. This part was not consistently regulating the signals sent to the blower and furnace control boards, causing the erratic behavior noted by the homeowner. The issue was that the module would sometimes fail to send the proper start-up signal, leaving the furnace idle. At other times, it wouldn’t send a stop signal, causing the furnace to keep running even when the desired temperature was reached.

In cases like these, precision matters. Replacing the faulty module with a high-quality part specifically designed for York systems was the key to restoring the furnace’s normal function. We ensured that every connection was securely reattached, and each wire was checked for wear or potential issues that could lead to future failures.

Recalibrating and Testing the Central AC & Heat Pump

Once the furnace issue was resolved, we turned our attention to the central AC and heat pump. A malfunctioning furnace module can sometimes cause irregularities with the entire HVAC system, including the cooling side. After recalibrating the controls, we tested the central AC and heat pump extensively, simulating a range of temperature demands to ensure everything responded correctly and smoothly.

By addressing the root electronic problem and recalibrating the system, we were able to extend the life of this York central HVAC system significantly. Our client was thrilled to hear they wouldn’t need a costly replacement anytime soon and was comforted by the restored reliability of their HVAC system.

Frequently asked questions

What people ask us about this kind of work

9 questions
What should I have ready before calling?
The model (on the unit's label), the error code if there is one, the symptoms and how long they have lasted.
Repair or replace?
It depends on the unit's age, the failure and the cost of parts. We present the options after the diagnosis.
Can I keep my current ducts?
Often, yes: the central heat pump connects to the existing ducts. We check their condition and size during the estimate.
What happens in extreme cold?
The indoor module (furnace or air handler) works with the central heat pump and takes over in extreme cold.
Furnace, air handler, ducted: what is the difference?
The furnace or air handler is the indoor module of the central system. A ducted system hides in the ceiling: all you see are small supply grilles.
