Case: An Outdated System and a Competitive Quote

A homeowner in Knoxville discovered that their two aging HVAC units—each more than 20 years old—were still running but no longer efficient. While the system moved air without strange noises or visible damage, rising utility bills hinted at hidden issues. After another company provided a low‐cost estimate, HEP technicians stepped in to offer a more comprehensive evaluation.

During the initial walkthrough, a HEP technician detected a faint gas odor and shut off the supply as a precaution. Following a safe pressure test and a detailed comparison of proposals, the homeowner chose HEP for clear communication, expert advice, and thorough service.

Solution: High-Efficiency Split System Installation

HEP technicians replaced the old setup with a modern 2.5-ton split system, pairing a high-efficiency outdoor condensing unit with a 96% AFUE gas furnace. Over two days of work, they:

• Removed the aged coil and installed a new, refrigerant-ready heat exchanger.
• Mounted the outdoor unit on a level pad, adding insulated refrigerant lines and weather-protected wiring.
• Upgraded electrical connections and ensured proper grounding for safe operation.

Safety First: Gas and Electrical Upgrades

Safety checks are non-negotiable. After installation, a HEP technician:

• Leak-checked the new flexible gas connector and shutoff valve.
• Verified the breaker capacity and tightened all electrical terminations.
• Calibrated ignition controls and confirmed steady airflow throughout the ducts.

Final Checks and Peace of Mind

Before departing, the team used precision gauges and meters to confirm proper refrigerant charge and electrical performance. A final walkthrough with the homeowner covered thermostat operation, routine maintenance tips, and answers to any remaining questions.

Tips for Homeowners

• Shop Around: Compare detailed bids, but don’t choose based on price alone—look for clear explanations and safety procedures.
• Prioritize Safety: Always opt for a service that performs gas leak and electrical checks before installing new equipment.
• Maintain Clearance: Keep at least two feet of unobstructed space around your outdoor unit for proper airflow and easy service access.
• Check Warranties: Ask about parts and labor coverage to protect your investment.
• Schedule Routine Service: Annual tune-ups by qualified HEP technicians can extend equipment life and catch small issues early.

Performed in Knoxville by HEP technicians, this approach ensures reliable comfort, lower energy bills, and lasting peace of mind.
