This project involved a series of completed residential heating and air conditioning installations and changeouts across multiple properties in and around Chattanooga, including Hixson, Ooltewah, Ringgold, and Athens. The work focused on replacing aging or underperforming HVAC systems with new, high‑efficiency equipment, while ensuring each home received a system properly sized and configured for its specific layout and comfort needs.
The process began with on‑site evaluations at each address. Existing equipment was inspected for capacity, condition, duct compatibility, electrical requirements, and ventilation. Load calculations were performed where needed to confirm the correct tonnage and system type for each home. This step helped prevent both under‑ and oversizing, which can lead to uneven temperatures, humidity issues, and higher operating costs.
Once the appropriate equipment was selected for each property, the old indoor and outdoor units were carefully removed, including furnaces, air handlers, condensers, and any obsolete or incompatible components. Refrigerant was recovered in accordance with environmental regulations, and existing electrical and line‑set conditions were checked to determine whether upgrades were required.
New systems—primarily central air conditioning and heat pump configurations—were then installed. This included:
- Setting and leveling new outdoor condensers or heat pumps on pads or brackets suited to each site
- Installing or re‑configuring indoor units (furnaces or air handlers) in closets, basements, attics, or crawlspaces as needed
- Connecting or replacing refrigerant line sets, ensuring proper sizing, insulation, and routing
- Verifying and adjusting duct connections, sealing any accessible leaks, and modifying transitions to match new equipment dimensions
- Updating condensate drainage, including new drain lines, traps, and, where needed, condensate pumps
- Confirming proper electrical supply, including breakers, disconnects, and equipment grounding
New smart or programmable thermostats were installed in many of the homes to improve comfort control and energy management. In those cases, low‑voltage wiring was updated where necessary, and system settings were configured to match the installed equipment (staging, heat pump logic, fan operation, and schedules).
After installation, each system went through a detailed startup and checkout procedure. This included:
- Pulling and holding vacuum on the refrigeration lines to confirm system tightness
- Charging refrigerant to manufacturer specifications and verifying superheat/subcooling
- Measuring supply and return air temperatures, static pressure, and airflow to ensure proper operation
- Checking gas connections and combustion (for gas furnaces), verifying safe venting and ignition
- Confirming that emergency heat, defrost cycles (for heat pumps), and safety controls operated correctly
The final stage of each job involved walkthroughs with the homeowners. System operation was demonstrated, thermostat programming was reviewed, filter locations and replacement intervals were explained, and basic maintenance recommendations were provided. All work areas—indoor and outdoor—were cleaned up, with old equipment and debris removed from the properties.
Across this group of completed projects, the result is a set of homes in Chattanooga, Hixson, Ooltewah, Ringgold, and Athens now equipped with modern, efficient HVAC systems that provide more consistent temperatures, quieter operation, and improved reliability compared to the equipment they replaced.
