Lennox HVAC & Heating Equipment Leak Repair in Metro Vancouver

Lennox HVAC & Heating Equipment Leak Repair in Metro Vancouver

Lennox is a trusted brand in the world of home heating and cooling. Known for high-performance, energy-efficient systems, Lennox furnaces, air handlers, and HVAC units are common in homes and businesses across Metro Vancouver. But even high-quality equipment can develop issues over time—including one of the most urgent and costly: leaks.

Whether you’re noticing water pooling near your Lennox furnace, a damp ceiling under a Lennox air handler, or unusual condensation inside your heating equipment, ROMA Heating & Cooling provides expert Lennox HVAC leak repair services across Vancouver, Burnaby, Surrey, Richmond, Coquitlam, and beyond.

Is Your Lennox System Leaking? Here’s What You Might Be Seeing:

Leaks from HVAC systems can appear in several ways:

• Water pooling around your indoor furnace or air handler
• Dripping from ceiling vents (if unit is ceiling-mounted)
• Watermarks on the wall or ceiling
• Rust or corrosion around the base of your furnace or coil
• Moldy smells near your HVAC equipment
• Reduced heating efficiency or frequent shut-offs

These issues are especially common in high-efficiency Lennox systems, where condensation is part of normal operation—but only if it’s managed correctly by drains, pans, and pumps. When something goes wrong, it can lead to property damage, mold growth, and complete HVAC failure if left unaddressed.

Common Lennox HVAC Leak Sources We Repair

At ROMA Heating & Cooling, our certified technicians specialize in diagnosing and repairing leaks from all Lennox heating and cooling systems, including furnaces, air handlers, packaged units, and ducted heat pumps.

Here are the most common culprits:

✅ 1. Condensate Drain Line Clogs

High-efficiency Lennox furnaces (like EL296V, EL296E, SLP98V) and Lennox air handlers produce condensate water during operation. This water is normally drained through a PVC line. But over time, that drain can become clogged with:

• Dust and debris
• Algae and mold
• Slime or sediment

When blocked, water backs up into the furnace or air handler, eventually overflowing and leaking onto the floor—or worse, through the ceiling if installed in an attic or upper floor.

✅ 2. Cracked or Overflowing Drain Pan

If your Lennox air handler (e.g. CBX32M, CBX27UH, CBX40UHV) is leaking, a common cause is a cracked or rusted drain pan. Located under the evaporator coil, the pan collects condensate—but if it’s damaged or misaligned, water can escape into your home’s walls, insulation, or ceiling.

✅ 3. Coil Freezing and Thawing

Restricted airflow, low refrigerant, or thermostat malfunction can cause your evaporator coil to freeze. When it melts, the excess water may overwhelm the drain pan or spill outside of the intended flow path.

✅ 4. Condensate Pump Failure

If your Lennox HVAC system is installed in a basement or attic, it may rely on a condensate pump to move water to a drain. Pump failure leads to immediate water backup and spillage.

✅ 5. Humidifier Leaks (Bypass or Powered)

Many Lennox furnaces are paired with integrated whole-home humidifiers. If the humidifier pad is clogged, the drain line is disconnected, or the solenoid valve fails, water can leak onto or inside the furnace.

✅ 6. Flue Pipe or Venting Leaks

In high-efficiency Lennox furnaces, improperly sealed PVC flue pipes can allow condensation to escape into the unit or surrounding area—especially if joints are loose or sloped incorrectly.

✅ 7. Internal Heat Exchanger Cracks

Though less common, a cracked heat exchanger in older or heavily used Lennox furnaces can lead to internal leaks and even dangerous carbon monoxide exposure. This requires immediate inspection.
