When an HVAC system begins to lose its cooling power, many homeowners assume the unit is simply “getting old.” However, the culprit is often hidden deep within the mechanical heart of the system. Recently, the experts at Go Air Ducts completed a high-impact restoration project in Austin, TX, where a neglected evaporator coil and blower motor were severely throttling a home’s comfort and energy efficiency.
The Austin climate is notorious for high humidity and heavy seasonal pollen, which creates a challenging environment for air conditioning units. In this specific case study, the homeowner noticed that despite the AC running constantly, the house never quite reached the desired temperature. Additionally, their monthly utility bills had spiked significantly compared to the previous year.
Upon arrival, our technicians performed a diagnostic check and identified two critical failures: a caked evaporator coil and a debris-laden blower motor. The evaporator coil is responsible for heat exchange; when it is covered in dust, it acts as an insulator, preventing the refrigerant from absorbing heat from the air. Simultaneously, the blower motor, the “fan” that pushes air through your home, had accumulated enough grime on its blades to lose its aerodynamic balance and speed.
Unlike a surface-level cleaning that many providers offer, our team opted for a deep cleaning through physical extraction. This method is the “gold standard” for HVAC restoration because it allows for 360-degree access to components that are otherwise unreachable while inside the air handler cabinet.
The blower wheel consists of dozens of small “fins.” Even a millimeter of dust buildup on these fins can reduce airflow by as much as 20%. Our team carefully disconnected and removed the blower assembly. Using specialized compressed air and precision brushes, we stripped away years of compacted dust. This process not only restores airflow but also reduces the physical strain on the motor, preventing a costly mechanical burnout.
The evaporator coil is the most sensitive part of the system. Because it is often damp with condensation, it acts like a magnet for dust and organic growth. In this Austin home, the coil was “impacted,” meaning the air could barely pass through the copper fins. Once removed, we applied an EPA-approved, non-acidic foaming cleanser that penetrates deep into the fins to dissolve buildup. After a thorough rinse and inspection, the coil was restored to a like-new condition, ensuring maximum heat transfer.
In Central Texas, the HVAC system is often the single largest consumer of electricity in a household. According to the U.S. Department of Energy, dirty coils can increase a system’s energy consumption by up to 30%. Furthermore, a dirty blower motor can lead to poor “static pressure,” which means the rooms furthest from the unit will never get enough cool air.
By investing in a deep clean, this homeowner didn’t just fix a cooling problem; they protected their investment. The average lifespan of an HVAC unit in Austin can be shortened by several years if it is forced to operate under the stress of restricted airflow.
After the components were meticulously cleaned and dried, the Go Air Ducts team reinstalled the blower and coil back into the system. This stage requires precision to ensure all seals are airtight and electrical connections are secure.
Once the system was powered back on, we performed a Post-Cleaning Performance Test. The results were remarkable:
While regular air duct cleaning is essential, the blower and coil are the components that do the “heavy lifting.” For homes in Austin, TX, where the AC runs for nearly nine months of the year, these parts require professional attention.
Highlighting the Key Advantages:
To maintain these results, we recommend that homeowners in the Austin area replace their filters every 30 to 90 days and consider a professional air duct cleaning every few years to prevent dust from reaching these critical internal components again.
If your air conditioner is struggling to keep up with the Texas heat or your energy bills are higher than they should be, the solution is likely hidden inside your air handler. At Go Air Ducts, our expert technicians specialize in the deep cleaning of blowers and coils, ensuring your system operates at peak efficiency. We take the time to do the job right, removing, cleaning, and testing every component so you can enjoy lower costs and cleaner air.
