Evaporator coils are a key part of your HVAC system and shouldn't be ignored during home upkeep. If these coils get dirty, they can't send out cool air, and instead, they pull in warm air from inside your home. This can cause big issues, such as rising energy costs and a decline in your home's comfort levels. America's Home Services' latest AC unit repair project discusses how cleaning your evaporator coils can cut down on these problems and bring additional advantages!

Fixing a Home Cooling Problem

We will examine a service call to a residential property where a technician was dispatched to assess and address issues with the HVAC (Heating, Ventilation, and Air Conditioning) system. The homeowner reported cooling problems, and upon arrival, the technician identified multiple issues with the system.

A homeowner contacted our company to report that his HVAC system was not cooling the house effectively. In response to the service call, Our technician arrived at the property to diagnose and rectify the issue. The following observations were made during the initial inspection:

  • Frozen Evaporator Coil: Upon inspecting the unit on the roof, Technician John discovered that the indoor evaporator coil was completely frozen over. This was impeding the unit's ability to provide adequate cooling.
  • Dirty Evaporator Coil: The indoor evaporator coil was found to be heavily coated with dirt and debris, reducing its efficiency.
  • Rust Damage: There was noticeable rust damage to the indoor evaporator coil, raising concerns about potential Freon leaks due to corrosion.

Recommended Repairs:

After a thorough assessment, our technician recommended the following repairs and maintenance:

  • De-Icing: The first step was to melt the ice on the evaporator coil using a hose to allow for a proper diagnostic.
  • Cleaning: The indoor evaporator coil required a thorough cleaning to remove accumulated dirt and debris, restoring its efficiency.
  • Rust Treatment: Due to the extensive rust damage, an acid cleaning procedure was proposed to address the corrosion issues.
  • Refrigerant Recharge: The HVAC system needed a recharge of R410a refrigerant, estimated between 1 to 5 pounds.
  • Stop Leak Dye: To potentially address Freon leaks caused by rust damage, the addition of a stop leak dye was recommended.

The client was informed that the recommended repairs were a temporary solution, given the age and condition of his HVAC unit, which had exceeded its typical lifespan for Chandler AZ's climate. The technician made it clear that there would be no warranty on the stop leak seal and refrigerant recharge, as they might serve as a temporary fix until Mr. Smith decides to replace the entire HVAC system. The client agreed to proceed with the temporary repairs.

Following the agreed-upon repairs and maintenance, the HVAC system was operational again. The temperature split at the elbow was measured at 20 degrees, indicating improved cooling efficiency. However, we noted that the compressor was running close to its maximum amperage.

The client was informed that the cost of today's repairs would be applied as a credit toward the purchase of a new HVAC unit if they chose to replace it within the next 90 days, given the unit's age and condition.

This project highlights the importance of regular HVAC system maintenance and the challenges posed by aging units, especially in harsh climates like Chandler AZ. In this instance, the technician provided a temporary solution to restore cooling functionality while advising the homeowner about the inevitable need for a system replacement in the near future.
