The HEP HVAC Replacement Process

Initial Assessment and Load Calculation

HEP begins every project with a detailed review of your home’s square footage, insulation levels, window orientation, and occupancy patterns. Manual J load calculations confirm the exact heating and cooling demands, preventing oversizing or undersizing—both common issues that lead to wasted energy and diminished comfort.

Equipment Selection Tailored to Sewanee Homes

Once the thermal load is known, HEP matches the residence with equipment that boasts high SEER (Seasonal Energy Efficiency Ratio) for cooling and high AFUE (Annual Fuel Utilization Efficiency) for heating. Local climate data for Sewanee’s elevation ensures that the selected capacity can handle both peak summer humidity and brisk winter nights.

Ductwork Inspection and Optimization

Replacing the main HVAC unit without evaluating ducts can leave efficiency on the table. HEP technicians pressure-test the distribution system, seal leaks, and adjust airflow balancing dampers. Proper duct performance safeguards new equipment and maximizes comfort in every room.

Professional Removal of the Outdated Unit

The team safely disconnects power, refrigerant lines, and gas connections (for furnaces) in accordance with EPA and local regulations. Old refrigerant is recovered, and all obsolete components are prepared for responsible recycling.

Precise Installation of the New System

HEP positions the new air handler, furnace, or heat pump on vibration-isolating pads. Refrigerant lines are brazed with nitrogen purging to eliminate oxidation, and all joints receive pressure testing. Electrical wiring adheres to NEC codes, and condensate drainage routes are checked for proper slope.

Performance Verification and Commissioning

After charging the system with manufacturer-specified refrigerant levels, technicians measure superheat, subcooling, static pressure, and airflow. Only when readings fall inside design criteria is the installation considered complete.

Post-Installation Walk-Through and Support

Homeowners receive an in-depth orientation covering thermostat programming, filter replacement schedules, and energy-saving tips unique to Sewanee’s microclimate. Documentation of warranty terms and maintenance recommendations rounds out the visit.

Heating Systems HEP Replaces in Sewanee

Furnace Replacement

Gas and electric furnaces operate at the heart of many Sewanee homes. HEP installs modern models that achieve AFUE ratings up to 98%, translating into significantly lower fuel consumption. Variable-speed blower motors further boost efficiency by matching airflow to real-time demand.

Heat Pump Upgrades

For households favoring all-electric solutions, a high-efficiency heat pump offers both heating and cooling. Current-generation inverter technology enables these systems to perform reliably even when outdoor temperatures drop below freezing—an essential feature in mountain communities.

Hybrid Heating Solutions

A dual-fuel or hybrid system combines a heat pump with a high-efficiency gas furnace. The result is a platform that automatically chooses the most economical energy source based on outdoor temperature, maximizing comfort while minimizing operating costs.

Cooling Systems HEP Replaces in Sewanee

Central Air Conditioner Replacement

Traditional split-system air conditioners remain a popular choice for sizable homes. Replacing an aging 10-13 SEER model with a 16-20 SEER unit can slash cooling expenses and improve dehumidification, a must in Tennessee summers.

High-Efficiency Inverter Systems

Variable-speed inverter technology delivers only the cooling necessary at any given moment, reducing energy spikes and maintaining set temperatures within a narrow range. Inverter systems also run noticeably quieter—a welcome change for patios and decks.

Ductless Mini-Split Upgrades

Older additions, sunrooms, or converted garages lacking ductwork can benefit from ductless replacements. Indoor heads mount discreetly and provide zoned temperature control, eliminating the need for window units or space heaters.

Energy Efficiency and Environmental Responsibility

Homeowners increasingly seek eco-friendly solutions, and HVAC replacement ranks among the most impactful upgrades.

• Lower greenhouse gas emissions due to reduced energy consumption
• Transition from R-22 to environmentally safer R-410A or R-454B refrigerants
• Optional energy-recovery ventilators (ERVs) that capture heat from exhaust air
• Ability to integrate solar-ready equipment and high-performance insulation strategies

Indoor Air Quality Enhancements That Accompany Replacement

Advanced Filtration Options

Media filters rated MERV-13 or higher capture pollen, mold spores, and fine dust. HEP routinely configures new systems with filter cabinets that simplify maintenance and improve air cleanliness.

Humidity Control

Whole-house humidifiers and dehumidifiers interface seamlessly with modern HVAC controls. Balanced humidity curbs mold growth, protects woodwork, and enhances overall comfort.

Smart Thermostat Integration

Wi-Fi-enabled thermostats provide real-time monitoring of temperature, humidity, and filter status. Geofencing functions automate temperature setbacks when the home is unoccupied, further reducing energy consumption.

The Role of Proper Sizing in HVAC Replacement

Manual J Load Calculations

A cornerstone of HEP’s methodology is performing accurate load calculations rather than relying on rule-of-thumb tonnage estimates. This attention to detail prevents the common pitfall of oversizing, which leads to short cycling, poor humidity removal, and accelerated component wear.

Avoiding Short Cycling and Excessive Run Times

Properly sized equipment enjoys longer, steadier run cycles that maintain even temperatures and maximize energy efficiency. By contrast, undersized units struggle to meet demand, while oversized units shut down too quickly, leaving moisture behind.

How HEP Protects Your Sewanee Property During HVAC Work

Clients often worry about dust, debris, and potential damage. HEP’s replacement protocol places a premium on jobsite cleanliness and respect for the home environment.

• Floor runners and protective shoe coverings
• Sealed plastic containment zones around work areas
• Magnetic drop cloths to capture metal filings during sheet-metal modifications
• Thorough vacuuming of the site, including nearby duct registers
• Responsible recycling of old metal components and refrigerant
