A customer in Emory, TX reached out through Facebook saying their air conditioner wasn't keeping up with the heat and had been freezing up. Our technician arrived and got to work finding the cause.
The first thing we found was a brand-new air filter that was completely blocked — 100% restricted. A clogged filter starves the system of airflow, and poor airflow is one of the most common reasons an air conditioner freezes up. We also found the outdoor heat pump unit was heavily coated in dirt and debris.
We disassembled the outdoor unit and performed a foam wash from the inside out. This method pushes dirt and debris outward through the coil, giving it a much more thorough clean than spraying from the outside. A clean coil helps the system transfer heat properly and run more efficiently.
Next, we checked the attic and found the condensate drain line was clogged. A blocked drain line can cause water to back up and overflow, leading to water damage and humidity problems inside the home. We disassembled the drain line and flushed it completely clear.
By the time we finished, the system was cooling well and running the way it should. The customer was happy with the results. If your air conditioner is struggling to keep up or you notice ice forming on the unit, these are signs it needs attention. Regular maintenance can prevent most of these issues before they become bigger problems.
