Adding Central Air Conditioning to an Existing HVAC System in Teton, Idaho
October 1, 2026


Payne Air Conditioning Installation in Teton, Idaho
Big Foot Heating & Cooling completed a Payne air conditioning installation in Teton, Idaho, adding a new 3-ton central cooling system to the home’s existing furnace. The project included a Payne 14 SEER2 outdoor air conditioning unit paired with a Bryant indoor evaporator coil, allowing the homeowners to add central cooling without replacing their entire heating system.
The installation paired a Payne 14 SEER2 outdoor air conditioning unit with a Bryant indoor evaporator coil. Before beginning the work, our team evaluated the existing HVAC system, ductwork, thermostat wiring, basement access, and electrical layout to plan the installation.
The home already had suitable thermostat wiring and accessible basement space for routing the new refrigerant lines and electrical connections. These existing features helped guide the installation plan and integration with the furnace.
Equipment Selection and Installation Details
The Payne air conditioning system was selected to provide central cooling while working with the home’s existing furnace. Pairing the outdoor unit with a Bryant indoor evaporator coil allowed Big Foot Heating & Cooling to add cooling without replacing the entire HVAC system.
For this project, Big Foot Heating & Cooling installed a Payne 14 SEER2 air conditioning system paired with a Bryant indoor evaporator coil. The new system was designed to work alongside the home’s existing furnace, providing central cooling without requiring a complete HVAC replacement.
The installation included:
- Payne 3-ton central air conditioning condenser.
- Bryant indoor evaporator coil.
- New refrigerant lines connecting the indoor and outdoor equipment.
- Outdoor condenser pad and equipment anchoring.
- New electrical connections between the home’s electrical panel and outdoor AC unit.
- New electrical whip and low-voltage wiring.
- Condensate drainage components and installation materials.
- Required labor and permitting.
The home’s unfinished basement provided access for routing the new refrigerant lines and electrical wiring. During the initial assessment, our technicians also identified an unused dryer vent opening as a potential route for the refrigerant lines, helping simplify the planned connection between the indoor and outdoor equipment.
The electrical work included running a dedicated connection from the home’s electrical panel to the new outdoor AC unit.
Air Conditioning Installation and System Testing
After the Payne air conditioning unit was installed, our technicians completed the refrigerant line connections, pressure testing, and system evacuation. These steps helped prepare the equipment for startup and verify that the installation was ready for operation.
A proper air conditioning installation involves more than positioning the outdoor condenser and connecting the indoor equipment. Refrigerant lines, electrical connections, drainage, and system controls all need to be properly integrated.
After installing the Bryant indoor coil and positioning the Payne outdoor condenser, our technicians completed the refrigerant line connections. The copper connections were brazed, followed by a nitrogen pressure test to check for leaks.
The refrigerant lines were then evacuated using a vacuum pump to remove moisture and unwanted gases before the system was charged and balanced.
Additional electrical and thermostat connections were completed to integrate the new air conditioner with the existing HVAC equipment. The installation concluded with a full system startup and operational test to verify proper operation.
Results and Benefits of Adding Central Air Conditioning
With the Payne air conditioning installation complete, the homeowners now have a central cooling system to complement their existing heating equipment. This approach adds summer comfort without requiring a full replacement of the home’s HVAC system.
