Case Study: When a Furnace Needs More Than a Tune-Up

A homeowner in Knoxville noticed uneven heating throughout the house and called HEP for help. During the visit, a HEP technician used an inspection camera to look inside the furnace and discovered cracks in the heat exchanger—a safety hazard that required the system to be locked out immediately. Rather than patching an aging unit, the homeowner reviewed repair versus replacement options and chose to upgrade to a modern heat pump. Financing was arranged, a five-star review was left, and now a skilled crew will return to install a new split-system setup.

Spotting Early Warning Signs

Most homeowners wait until a system fails completely before calling for help. Here are a few things to watch for:

Uneven temperatures in different rooms
Unusual noises or rattling from the furnace
Soot, rust, or water stains near the equipment
Rising energy bills without a change in usage

Catching these clues early can save you from an emergency and help a HEP technician diagnose potential issues before they become costly breakdowns.

Here's a peek at how we use specialized cameras to find hidden cracks before they lead to bigger problems.

Why Replacement Can Be the Best Option

If your system is over 10–15 years old or has significant internal damage, a full replacement often delivers better long-term value:

Improved energy efficiency with modern equipment
Enhanced safety, avoiding risks like carbon monoxide leaks
Consistent, reliable comfort year-round
Manufacturer warranties for peace of mind

Once the decision is made, the installation crew arrives with the right gear and expertise.
