When your air conditioner suddenly starts making a racket, it’s usually a sign that something’s working harder than it should. Recently, our team helped a homeowner in New Braunfels get her older HVAC systems checked out, and gave her peace of mind that everything was running safely and efficiently.
The Job Overview
Amanda in New Braunfels reached out to us when one of her smaller HVAC units began making loud noises during startup. Since her systems were more than eight years old, she decided to schedule a full tune-up and have all three units inspected at once.
What We Found
Our inspection revealed that one of the two-ton systems was low on refrigerant, which caused the compressor to strain and create loud startup noises. We also noted that while some components had been replaced in recent years, other equipment, including the furnace and outdoor coils, showed signs of age and wear.
What We Found
-
Older Furnace Still in Service
Indoor coil was newer, but the original furnace and duct connections showed age and wear affecting performance. -
Low Refrigerant at Outdoor Unit
One system was low on refrigerant, forcing the compressor to work harder and causing loud startup noises. -
Compressor Overamping
Field measurements showed nearly 5 amps, higher than expected, confirming strain from low refrigerant.
The Solution
We performed a full maintenance service across all three HVAC systems, including cleaning and testing to bring everything back to proper operating standards. To further improve performance and reduce unnecessary strain, we recommended coil cleaning.
Amanda chose to move forward with our Care Club maintenance package, ensuring all her units were tuned up and ready for reliable operation.
-
Before Service
The system showed only a 14.5°F temperature drop – well below the ideal range. This explained why the unit was straining and creating loud startup noises. -
After Service
Testing confirmed a 24°F temperature drop between return and supply air, a clear sign the system was cooling efficiently again.
The Results
By resolving the refrigerant issue and performing preventative maintenance, Amanda’s HVAC systems now run more quietly and efficiently. This not only eliminated the loud startup noises but also extended the life of her equipment and improved her home’s comfort.
