A Case in Point: No Cold Air in a 13-Year-Old System

A Walland homeowner noticed her aging air conditioner would run but never deliver cool air. When our dispatcher booked the first available slot, a HEP technician arrived to troubleshoot the problem. Inside, the technician found low refrigerant levels, a corroded cooling coil, and bacterial buildup inside the plenum. Rather than patch a failing system, the homeowner chose a full replacement—a modern heat pump split that would restore reliable comfort.

Solution summary:
Our HEP technician installed a new 2½-ton heat pump split (R-454B), paired it with a matching air handler, built a sealed “coffin-style” plenum box treated with UV light to inhibit bacterial growth, and tested the setup for efficient performance.

Why Upgrading Can Be the Best Choice

Properly leveled and clear of debris, this new condenser delivers efficient cooling and quiet operation.

Age Matters: Systems over a decade old often suffer from leaks, corrosion, and worn-out components.
Refrigerant Changes: Modern refrigerants are more eco-friendly and operate at optimal pressures.
Energy Savings: Newer equipment typically carries higher SEER ratings, meaning lower electric bills.

Inside the Home: Clean, Efficient Air Delivery

The new air handler sits on a dedicated drain pan, and the sealed plenum helps prevent microbial growth.

Sealed Plenums: A well-sealed plenum keeps dust and bacteria from circulating.
UV Light Protection: Bonus UV lights can inhibit mold and bacterial buildup on coils.
Reliable Performance: New motors and controls run smoother and draw correct amperage for safety.

Professional Installation Protects Your Investment

All piping is insulated and sealed at the wall entry; the disconnect box is mounted safely and level.

Correct Sizing: A two-and-a-half-ton split system was specified to match the home’s cooling load.
Proper Sealing: Caulking around line-set entries prevents energy loss and moisture intrusion.
Electrical Safety: The disconnect box and wiring meet local code for secure shut-off access.

Homeowner Tips from HEP Technicians

Watch for Weak Airflow or Lukewarm Output: Early signs of low refrigerant or clogged coils.
Schedule Seasonal Tune-Ups: A spring check can catch leaks, dirty coils, or failing components.
Inspect the Plenum and Ducts: Look for mold, rust, or loose insulation—air quality depends on it.
Clear Around Outdoor Units: Keep at least two feet of clearance to maintain airflow and efficiency.
Ask About UV Lights: Adding germicidal UV can extend coil life and improve indoor air quality.

By consulting a qualified HEP technician, Walland homeowners can enjoy safe, efficient cooling—and peace of mind knowing their systems are backed by solid warranties and professional expertise.
