When any of these warning signs appear, HEP’s seasoned technicians can evaluate overall system health, run load calculations, and recommend a tailored replacement strategy, ensuring every indoor square foot receives balanced heating and cooling.

The HEP Approach to HVAC Unit Replacement

Replacing an entire HVAC system is far more than a drop-and-swap procedure. A thoughtful, data-driven approach helps ensure longevity, efficiency, and reliability.

Step-By-Step Assessment

Home Energy Audit

HEP begins with a whole-home energy audit. By measuring insulation levels, examining ductwork integrity, and evaluating window performance, they establish a baseline of how the property currently gains or loses heat. These insights guide equipment sizing.

Manual J Load Calculation

A precise Manual J load calculation determines the correct capacity required. Oversizing leads to short-cycling and moisture control issues; undersizing forces a unit to run continuously. Right-sizing guarantees comfort without waste.

Ductwork Evaluation

Leaky, poorly insulated ducts can reduce delivered efficiency by 20–30%. Technicians inspect joints, measure static pressure, and test for airflow restrictions. Repair or replacement recommendations accompany the HVAC unit proposal to protect the homeowner’s investment.

Selection of Equipment

HEP partners with trusted manufacturers to deliver furnaces, air conditioners, heat pumps, and air handlers designed for the South’s fluctuating temperatures.

• High-efficiency variable-speed air conditioners
• Dual-fuel hybrid heat pumps for efficiency across seasons
• Modulating gas furnaces capable of fine temperature control
• High static pressure air handlers for complex duct layouts
• Indoor air quality add-ons such as media filters, UV lights, and whole-home dehumidifiers

Energy Star-rated models dominate the lineup, ensuring every installation meets or exceeds current efficiency standards.

Installation Excellence

Proper installation is the linchpin of any replacement project. Even premium equipment loses performance without meticulous workmanship.

Equipment Positioning and Mounting

Indoor and outdoor units must be level, secure, and positioned for adequate service clearance. Technicians also factor in airflow patterns around the condenser to prevent recirculation of hot exhaust air.

Refrigerant Line Installation

New copper line sets protect a compressor from contaminants left in old piping. HEP brazes joints with inert gas purging, vacuum-tests down to industry-standard micron levels, and weighs in the exact refrigerant charge specified by the manufacturer.

Electrical and Control Wiring

A clean wiring job prevents shorts and aids future servicing. From installing dedicated disconnect boxes to calibrating thermostat controls, every conductor receives a labeled termination point.

Airflow Balancing

After startup, technicians measure supply and return airflow, adjust dampers, and set fan speeds to lock in proper static pressure. Balanced airflow eliminates hot and cold spots while preserving equipment longevity.

Tailoring HVAC Solutions to Hixson’s Climate

Humid Summers
