Remember that evaporator coil cleaning we posted about the other day? Yesterday, we had a great example of why we prefer to remove the coil when possible for a more thorough cleaning.
This customer called us for a second opinion after another company recommended replacing their evaporator coil and condenser for around $8,000 because their system was leaking and kept freezing up.
When we arrived, we immediately noticed that insulation and other debris had fallen into the coil from the flex duct above it, severely restricting airflow. Because of the tight space, we couldn’t properly reach the back of the coil, so we removed it for a thorough chemical cleaning and cleared out all the debris.
Once everything was clean, we discovered there actually was a refrigerant leak coming from a connector where the evaporator coil screwed into to the refrigerant line. We cut out the faulty connector and brazed the copper tubing back together to repair the leak.
After the repair, the system held pressure and pulled a vacuum with no problem, telling us that there were no significant leaks.
Now the system has better airflow, the leak has been repaired, and the customer has working AC for $7,000 less than the replacement they were quoted.
