Carrier 59TP7A Performance 97% AFUE Two-Stage Gas Furnace – Supplied & Professionally Installed by 4Most Energy
The Carrier 59TP7A Performance Series is designed for residential heating applications where efficient operation, two-stage heating, and flexible installation are important. The furnace combines a two-stage gas valve with a variable 25-speed constant-torque ECM blower motor and two-speed inducer motor. This allows the system to adjust heating and airflow operation rather than relying solely on a basic single-stage furnace. The 59TP7A achieves up to 97% AFUE in upflow installations, with six available furnace sizes ranging from 60,000 to 120,000 BTUh input.
The furnace uses an aluminized-steel primary heat exchanger, stainless-steel condensing secondary heat exchanger, and Silicon Nitride Power Heat hot-surface igniter. Its fully insulated casing includes the blower section.
Installation is flexible because the 59TP7A uses a 4-way multipoise cabinet, allowing upflow, downflow, or horizontal installation. Depending on the installation configuration and applicable requirements, the furnace can use direct-vent/two-pipe, single-pipe, or ventilated-combustion-air arrangements. Sidewall or vertical venting is supported.
Proper sizing is essential. Carrier states that the furnace should be selected to provide 100% of the calculated design heating load, with an appropriate allowance for available model increments. The manufacturer recommends an approved heating-load calculation method such as ACCA Manual J and S or another approved engineering method. Oversizing can contribute to discomfort and premature furnace or vent problems.
Gas supply, venting, combustion air, condensate drainage, electrical connections, clearances, and system airflow must all be addressed during installation according to the manufacturer's installation instructions and applicable codes.

Important Sizing Information
Carrier recommends using ACCA Manual J and S, ASHRAE methodology, or another approved engineering method to calculate the heating load and select the furnace. The manufacturer states that none of the listed model sizes should be used where the heating load is 20,000 BTU or lower.
4Most Energy recommendation: Final model selection should be completed after evaluating the home's heating load, ductwork, airflow requirements, existing equipment, installation configuration, and applicable site conditions.
Our Furnace Installation Process
1. Request Installation Quote Provide details about the existing furnace, home, and heating requirements so the installation can be assessed.
2. System Sizing Consultation The required furnace capacity is determined from the home's heating-load requirements rather than square footage alone.
3. Equipment Recommendation An appropriate 59TP7A capacity and cabinet configuration can then be selected based on the calculated requirements.
4. Installation Scheduling Arrange an installation date after the equipment and project requirements have been confirmed.
5. Removal of Existing Equipment Where applicable, the existing furnace is removed to prepare the installation area.
6. Installation & System Connection The furnace is positioned in the appropriate orientation and connected to the gas, electrical, venting, condensate, ductwork, thermostat, and required accessories.
7. Safety Testing Gas, electrical, venting, combustion, condensate, airflow, and operational requirements are checked as applicable.
8. Final Commissioning The furnace is started and adjusted according to the manufacturer's startup and adjustment procedures.
Carrier's installation manual covers combustion air, condensate drainage, furnace installation, filters, ductwork, gas piping, electrical connections, venting, startup, adjustment, safety checks, and commissioning procedures.

Frequently Asked Questions
What is the main benefit of the Carrier Performance 59TP7A?
The Carrier 59TP7A combines two-stage heating with a variable 25-speed constant-torque ECM blower. This allows the furnace to adjust heating and airflow operation for more consistent indoor comfort while achieving up to 97% AFUE in upflow installations.
How efficient is the Carrier 59TP7A furnace?
The 59TP7A is rated up to 97% AFUE in upflow applications. The actual AFUE rating varies by installation position, with manufacturer-listed ratings of 95% for downflow and approximately 96.1%–96.7% for horizontal installations, depending on the model.
What is the difference between the Carrier 59TP7A and 59TP6?
Both are Performance Series two-stage condensing gas furnaces, but the 59TP7A offers up to 97% AFUE in upflow installation and uses a variable 25-speed constant-torque ECM blower. The 59TP7A also features a 35-inch-tall cabinet and is available in six configurations from 60,000 to 120,000 BTUh input.
What sizes does the Carrier 59TP7A come in?
The 59TP7A is available in six configurations:
- 60,000 BTUh
- 80,000 BTUh with 17.5-inch cabinet
- 80,000 BTUh with 21-inch cabinet
- 100,000 BTUh with 21-inch cabinet and up to 2,170 CFM cooling airflow
- 100,000 BTUh with 21-inch cabinet and up to 2,250 CFM cooling airflow
- 120,000 BTUh with 24.5-inch cabinet
The two 80,000 BTUh models differ primarily in cabinet width and airflow capability, while the two 100,000 BTUh configurations have different airflow ranges.
How do I know which 59TP7A size is right for my home?
Furnace sizing should not be based on square footage alone. Carrier recommends calculating the home's design heating load using an approved method such as ACCA Manual J and S, ASHRAE methodology, or another approved engineering method.
Our team can evaluate the home's heating requirements, ductwork, airflow, existing equipment, and installation configuration to recommend the appropriate model.
What is the difference between the two 80,000 BTU 59TP7A models?
The 80,000 BTUh models have different cabinet and airflow configurations. The 17.5-inch model has a cooling airflow range of 255–1,625 CFM, while the 21-inch model provides a higher cooling airflow range of 270–2,110 CFM.
The correct configuration depends on the furnace application, ductwork, required airflow, and overall system design.
What is the difference between the two 100,000 BTU 59TP7A models?
Both models have a 100,000 BTUh input and 21-inch cabinet, but their airflow ranges differ. The 100V21–20 model has a cooling airflow range of 340–2,170 CFM, while the 100V21–22 model ranges from 525–2,250 CFM.
The higher-airflow configuration may be appropriate where the system requires greater air delivery, but final selection should be based on the complete HVAC system design.
Can the Carrier 59TP7A be installed horizontally or downflow?
Yes. The 59TP7A features a 4-way multipoise design that allows upflow, downflow, and horizontal installation. The furnace can also be configured for different approved venting and combustion-air arrangements depending on the installation.
Can the Carrier 59TP7A run on propane?
Yes. The furnace is manufactured for natural gas but can be converted to propane using the appropriate factory-approved gas conversion kit. The conversion must follow the manufacturer's requirements.
Does the 59TP7A work with a heat pump?
Yes. The 59TP7A is identified by Carrier as compatible with its HYBRID HEAT® dual-fuel applications. This allows the furnace to be integrated into an appropriate heat-pump and furnace system.
