Clearer Air, Smoother Operation: A Johnson City Home’s HVAC Makeover

Case Overview
A homeowner in Johnson City realized their more-than-12-year-old HVAC system was struggling. Strange odors wafted through the vents, the condensate pump had begun to groan, and heating and cooling didn’t feel as steady as it once did. Concerned about indoor air quality and long-term equipment wear, they called in HEP for expert guidance.

Diagnosis and Proposal
When the HEP technician arrived, they performed a room-to-room walkthrough and a unit inspection. Here’s what they recommended in plain language:

  • Add a UV purification lamp in the main return duct to help neutralize mold and bacteria.
  • Install a dedicated transformer so the lamp has its own safe power source.
  • Place an air-quality sensor to monitor improvements over time.
  • Double-check gas pressures on the heating side to confirm the system is burning fuel efficiently.

Control Transformer Installation

By breaking down each step, the HEP technician helped the homeowner see how these upgrades would tackle lingering smells, reduce moisture-related wear, and keep the system operating smoothly.

Solution and Results
On service day, the HEP technician got to work:

  1. Mounted the Scorpion UV lamp inside the return duct.
  2. Added a separate transformer and wired it into the control board.
  3. Installed the air-quality sensor and connected it to the distribution panel.
  4. Ran a full Quality Check Analysis (QCA), measuring airflow, refrigerant charge, and gas pressures.

UV Light in Return Duct

Every measurement landed within the manufacturer’s recommended range. The system hummed quietly, the pump ran smoothly, and the homeowner immediately noticed fresher, cleaner air. The HEP technician confirmed final readings, cleaned up the work area, and left the home ready for many more years of reliable comfort.

Key Takeaways for Homeowners

  • UV Air Treatment: Adding a UV lamp can reduce airborne microbes and odors in your ductwork.
  • Dedicated Power: A separate transformer keeps new accessories from overloading existing circuits.
  • Regular Tune-Ups: Annual checks of gas pressures and airflow prevent efficiency losses.
  • Condensate Maintenance: Pumps and drains should be inspected to avoid water damage.
  • Trust the Pros: A HEP technician explains each option clearly so you know what you’re paying for—and why it matters.

This Johnson City project illustrates that even an aging HVAC system can get a new lease on life with the right enhancements. If your system is over ten years old or you’ve noticed changes in performance or air quality, schedule a professional assessment to keep your home comfortable and healthy.
