Why a Deep Blower Cleaning Made All the Difference

When a Houston homeowner called Hage Energy, their system was running, but not performing. Our technician got to work and found the source of the problem almost immediately: a heavily contaminated blower assembly and a fouled evaporator coil that were robbing the system of efficiency.

Here's exactly what was done and why it matters.

What We Found

Over time, dust, debris, and grime accumulate inside the blower wheel and housing, the components responsible for moving conditioned air through your entire home. When buildup coats the blower wheel blades, it disrupts airflow, throws the wheel off balance, and forces the motor to work harder to move the same amount of air. Combined with a dirty evaporator coil, the system was working overtime to deliver underwhelming results.

What We Did

• Blower Assembly Removal and Chemical Cleaning: Our technician removed the blower assembly completely to access the wheel and housing. Both were chemically cleaned to remove the accumulated buildup, restoring the blade surfaces and allowing the wheel to move air the way it was designed to.
• Evaporator Coil Chemical Cleaning: With the blower out, we also chemically cleaned the evaporator coil. A clean coil surface is essential for proper heat and moisture transfer. Buildup acts as insulation, blocking the refrigerant from doing its job and causing the system to run longer and less efficiently.
• Blower Door Insulation: The blower door insulation had come loose, which allows unconditioned air to enter the system and conditioned air to escape. Our technician resecured it before closing everything up, a small detail that makes a real difference in system efficiency.

The Result

Once everything was reassembled and powered up, the system came up and operated normally. A temperature reading of 47°F at the plenum box confirmed the system was pulling heat and humidity out of the air effectively, right where it should be for efficient cooling performance.

What This Means for Your System

Most homeowners never think about their blower wheel, but it's one of the hardest working components in the entire system. A contaminated blower wheel can reduce airflow significantly, increase energy consumption, and put strain on the motor over time. When combined with a dirty evaporator coil, the efficiency losses compound.

If your system has never had a blower cleaning, or it's been a few years since your last professional maintenance visit, it may be working a lot harder than it needs to.
