Big Foot Heating & Cooling completed a central air conditioning installation in Victor, Idaho, adding a Bryant Legacy 14 SEER air conditioning system to the home’s existing indoor air handler. The project gave the homeowners central cooling without requiring a complete replacement of their existing heating equipment.

Adding air conditioning to an existing HVAC system requires careful coordination between the indoor and outdoor components. For this project, technicians installed a new AC coil alongside the existing air handler and connected it to a new outdoor condenser. This approach allowed the home to gain central cooling while retaining the existing heating equipment.

Central Air Conditioning Installation for an Existing HVAC System

This central air conditioning installation involved adding a new Bryant outdoor condenser and connecting it to the home’s existing indoor HVAC equipment. The work included the refrigerant, drainage, electrical, and thermostat connections needed to integrate the new cooling system.

The installation included:

• New Bryant Legacy 14 SEER outdoor air conditioning unit.
• Premade condenser pad with the outdoor unit anchored in place.
• New 3/4-inch refrigerant lines routed from the crawlspace through the foundation wall.
• New indoor AC coil connected to the existing air handler.
• New condensate pump and safety shutoff switch.
• Condensate drain line routed to the home’s laundry or bathroom sink plumbing drain.
• New thermostat control wiring.
• New 1/2-inch weather-rated electrical whip.

The new condensate pump and safety shutoff switch were installed as part of the drainage setup for the cooling system. Proper condensate drainage is an important part of an air conditioning installation because cooling equipment produces moisture as it operates.

By retaining the existing air handler and integrating the new cooling components, Big Foot Heating & Cooling was able to add central air conditioning without replacing the home’s entire HVAC system.

Refrigerant Line Installation and System Testing

A central air conditioning installation requires more than connecting the indoor and outdoor equipment. Refrigerant lines must be properly routed, connected, tested, and prepared before the system can be placed into operation.

For this Victor project, technicians routed the new refrigerant lines from the crawlspace through the foundation wall to the outdoor condenser. The lines were brazed and then pressure-tested with nitrogen to check for leaks.

After pressure testing, the refrigerant lines were evacuated using a vacuum pump to remove moisture and unwanted gases from the system. The system was then charged and balanced according to the installation requirements.

Technicians also completed the necessary electrical and thermostat connections before starting the system. A full startup and operational test was performed to verify that the new air conditioning system was functioning properly and communicating with the existing HVAC equipment.

These installation and testing steps are important when adding central cooling to an existing system because the new equipment must work properly with the home’s existing components.

Bryant Legacy Air Conditioning System

The Bryant Legacy air conditioning package installed for this project is a 14 SEER system designed for residential central cooling. The equipment includes several features intended to support reliable operation and protection of the outdoor unit.

Features listed for the installed system include:

• 14 SEER efficiency: Designed to provide efficient central air conditioning operation.
• Enhanced dehumidification: Helps remove moisture from indoor air during cooling operation.
• DuraGuard™ Plus protection: Provides added protection for the outdoor equipment.
• Puron® refrigerant: Uses an alternative refrigerant designed for air conditioning applications.

The new outdoor condenser was installed on a dedicated pad outside the home, while the indoor coil was connected to the existing air handler in the crawlspace.

The project also included a new thermostat control connection, allowing the new cooling equipment to operate through the home’s existing control setup.

Results of Adding Central Air Conditioning

With the new Bryant Legacy system installed, this central air conditioning installation gave the Victor home central cooling while retaining the existing heating equipment.

For homeowners with an existing HVAC system that does not include air conditioning, adding central cooling can be an alternative to replacing the entire system. The feasibility of an installation depends on the home’s existing equipment, available space, electrical requirements, ductwork, and other site conditions.

In this project, Big Foot Heating & Cooling integrated the new air conditioning equipment with the home’s existing indoor setup and completed the supporting refrigerant, electrical, drainage, and thermostat work required for the installation.
