HEP’s Comprehensive Replacement Process

Replacing a heating and air conditioning unit involves more than disconnecting the old equipment and connecting a new box. HEP follows a multi-step protocol that guarantees safety, code compliance, and optimal performance.

Initial Assessment and Load Calculation

Before any recommendations are made, technicians perform a Manual J load calculation. This detailed evaluation considers:

• Square footage and ceiling height
• Insulation levels in walls, attic, and crawl space
• Window type, orientation, and shading
• Air infiltration rates and existing duct leakage

The load calculation ensures that HEP selects a system sized precisely for the property’s heating and cooling requirements. Oversized units short-cycle and waste energy, while undersized units struggle, leading to wear and tear.

Removal of the Outdated Unit

HEP technicians follow EPA guidelines when recovering refrigerant from the old air conditioner or heat pump, preventing environmental harm. Electrical connections are safely disconnected, and the unit is removed without damaging flooring, drywall, or landscaping. Any parts eligible for recycling are processed responsibly.

Precision Installation and Calibration

A new pad or platform is positioned for outdoor units to guarantee level placement and optimal airflow. Interior components such as the air handler, evaporator coil, or furnace are mounted with vibration-dampening techniques to minimize noise. Refrigerant lines, high-quality insulation, and properly trapped condensate drains are installed to manufacturer specifications. Finally, the system is charged with refrigerant to exact subcooling and superheat targets.

Post-Installation Testing and Walk-Through

Once the new HVAC unit is operational, HEP measures:

• Static pressure and air velocity in supply and return ducts
• Temperature differentials at key points around the home
• Voltage, amperage, and overall electrical performance

Technicians then explain system features, filter replacement intervals, and thermostat operation, ensuring homeowners feel confident in operating their new HVAC equipment.

Energy Efficiency Standards and SEER Ratings

Every replacement system installed by HEP meets or exceeds the latest Department of Energy (DOE) minimum efficiency guidelines. In the Southeast region, these standards are particularly stringent, demanding higher SEER ratings to address warm summers. Upgrading from an older 10-SEER unit to a modern 16-SEER or 18-SEER model can slash cooling energy consumption by up to 40 %. HEP keeps abreast of evolving regulations, so Erwin homeowners benefit from compliance and possible energy rebates.
