Seeing an OH OE / EHOE error code on your heat pump or air handler? In this video, we explain what this common code may mean on systems like Carrier, Midea, ACiQ, AC Pro, and MRCOOL units.

We’ll show you how to inspect the air handler display, check the overflow condensate safety sensor, and determine if water buildup is causing the issue. Many times, this happens when the primary drain line is clogged or the condensate pump has failed or is overfilled.

In this video, we cover:
✔️ What the OH OE / EHOE code means
✔️ How to check the secondary overflow sensor
✔️ Signs of a clogged condensate drain line
✔️ How to inspect a condensate pump
✔️ Why no power to the pump can trigger the error

If your HVAC system is showing this code, this guide can help you understand the possible cause before calling for service.

In today’s video, we highlight a small but critical detail that can impact your HVAC inspection.

During a recent heat pump air handler installation in Orange County, the city inspector required a GFCI outlet for the condensation pump. Since the pump works with water, this safety feature is essential to prevent electrical hazards by shutting off power instantly when a fault is detected.

🔧 Project Highlights:
• Heat Pump Installation: New air handler setup
• GFCI Protection: Required for condensation pump safety
• Code Compliance: Meeting city inspection requirements
• Electrical Safety: Preventing potential hazards

⚙️ What You’ll Learn:
• Why a GFCI outlet is required for condensation pumps
• How GFCI protection improves safety in HVAC systems

In today’s project, we upgraded a home’s HVAC system by installing a variable-speed AC unit paired with an existing gas furnace.

The existing Goodman furnace was previously installed, but to ensure proper performance and efficiency, it required a full reinstallation. We carefully reinstalled the furnace and sealed the furnace closet, return cabinet, and return cavity to improve airflow and system efficiency.

As part of the upgrade, we installed an evaporator coil on top of the furnace, along with a 5-inch high-efficiency filter cabinet to enhance indoor air quality.

Outside, a new condenser unit was installed on the patio. We also ran a brand-new refrigerant line set from the condenser all the way to the attic to complete the system.

🔧 Project Highlights:
• System Upgrade: Installed a variable-speed AC unit paired with an existing Goodman gas furnace
• Furnace Reinstallation: Reinstalled the existing furnace to ensure proper setup and operation
• Airflow Improvement: Sealed the furnace closet, return cabinet, and return cavity for maximum efficiency
• Indoor Upgrade: Installed an evaporator coil and a 5-inch high-efficiency filter cabinet for better air quality
• Outdoor Installation: Set up a new condenser unit on the patio
• Line Set Installation: Ran a brand-new refrigerant line from the condenser to the attic

⚙️ Work Completed:
• Variable-speed AC system installation
• Furnace reinstallation and sealing
• Evaporator coil installation
• High-efficiency filter cabinet installation
