Customer Story
One chilly morning in Knoxville, a homeowner discovered their heat pump had stopped blowing warm air. With two small children in the house, comfort and safety were top concerns. A HEP technician arrived, found a critical safety switch had cut power to the unit, and replaced it on the spot. After testing the system and confirming steady airflow, the family’s home was warm again—and they left a glowing five-star review.

Here are some practical tips for homeowners to help prevent or quickly resolve similar HVAC surprises.

1. Watch for Early Warning Signs

If your vents feel cool when they should be warm, or if your thermostat shows a wide gap between the set temperature and the actual room temperature, it’s time to call a pro.

2. Keep Safety Devices Functional

Many systems include flood or safety switches that shut down equipment at the first sign of moisture or electrical issues.

A regular check by a HEP technician ensures these devices work when you need them most.

3. Ensure Clear Access to Your Equipment

Clutter around your air handler or outdoor unit makes service visits slower and can hide problems.

Keep the area clear so technicians can work safely and spot issues quickly.

4. Document Your System’s Details

Snap a photo of the unit’s specification label—including model, serial numbers, and electrical requirements.

This speeds up part orders and diagnosis during maintenance calls.

5. Consider Upgrades for Efficiency

Older condenser units can still run, but they often cost more to operate and repair.

Upgrading to a modern, efficient unit can lower energy bills and boost comfort.

6. Trust Professional Maintenance

During routine visits, technicians check wiring, sensors, and safety switches to prevent unexpected breakdowns.
