The Situation

On a particularly warm day in Bluff City, a homeowner noticed that their air conditioner was no longer delivering cool air. Concerned about rising indoor temperatures, they called HEP for an inspection.

Diagnosis and Solution

A HEP technician examined the system and determined that a critical valve inside the cooling circuit had worn out. To keep the home comfortable while waiting for the replacement part, portable cooling units were provided. Once the new valve arrived:

• The HEP technician removed the old component and installed the new valve.
• Refrigerant lines were evacuated to remove air and moisture.
• The system was recharged with the correct amount of refrigerant.
• A series of pressure and leak tests confirmed everything was sealed and operating as intended.

Within minutes of finishing, cool air flowed through the vents again, and the homeowner’s comfort was fully restored.

Why Professional Care Matters

That small valve—technically known as a thermal expansion valve—controls the flow of refrigerant. If it fails, your system can lose cooling power or run inefficiently. Professional steps like vacuuming the lines and pressure-testing ensure there are no hidden leaks and that your system will keep running smoothly.

A properly installed air handler is the heart of your indoor comfort. Notice the clean lines and intact labels—signs of work done right.

Clear, accessible labeling on the outdoor unit helps with future maintenance and troubleshooting.

Well-secured panels and readable manufacturer information make regular check-ups faster and more reliable.
