What to Do When Your Heater Stops Working: A Knoxville Case Study

A Chilly Morning, a Frustrated Homeowner

Last winter in Knoxville, a homeowner discovered their heat wouldn’t turn on just as temperatures dipped below freezing. They reached out to HEP for help. A HEP technician arrived promptly to diagnose the issue and found that the gas valve on the aging system had failed. Faced with options—repair the old unit or install a new one—the homeowner weighed efficiency, cost and long-term reliability.

How We Solved It

  1. Diagnosis: The HEP technician confirmed that the control board was sending voltage but the valve itself was no longer operating.
  2. Options Presentation: Repair parts and a full replacement were both presented in simple terms, with clear pros and cons.
  3. Financing & Reassurance: With financing instantly approved, the homeowner still had reservations. The HEP technician took time to answer every question, restoring confidence in moving forward.
  4. One-Day Installation: By day’s end, a high-efficiency gas package unit was in place—complete with a new concrete pad, updated electrical disconnect, fresh thermostat and surge protection. A final system test confirmed everything worked perfectly, and the homeowner left a five-star review.

4 Tips for Homeowners from the HEP Technician

1. Schedule Seasonal Check-Ups
Even if your system seems fine, a professional tune-up in fall and spring can catch small issues before they leave you in the cold.

2. Keep the Area Clear
Trim plants, remove debris and maintain at least a two-foot clearance around outdoor units for proper airflow and easy access.

3. Ask About Surge Protection
Power surges can damage sensitive components. A basic surge protector at the disconnect box is a small investment for big peace of mind.

4. Verify a Level Installation
Proper drainage and performance start with a level pad. A simple tool such as a spirit level ensures your unit sits correctly—avoid settling or water pooling.
