4 Ton Goodman GZV9SA4810, AHVE60DP1300 18 SEER2 R-32 Inverter Heat Pump System
This complete 4-ton (48,000 BTU/h) Goodman inverter system matches the GZV9SA4810 side-discharge condenser with the larger AHVE60DP1300 variable-speed communicating air handler to condition bigger homes and open floor plans without sacrificing efficiency or quiet. Rated 18 SEER2 on R-32 refrigerant, the pair modulates capacity and airflow across a wide range for even temperatures throughout the house, plus dependable heat-pump heating when the weather turns cold.
Is a 4-Ton System the Right Size?
This high-capacity 4-ton system is typically specified for larger single-family homes, open-concept layouts, and two-story properties with a heavier combined load. Its inverter design is a real advantage at this size: instead of blasting on at full power and shutting off, the system scales output to demand, avoiding the temperature swings and noise that come with oversized single-stage equipment. The generously sized AHVE60DP1300 air handler supports the higher airflow these homes need.
Bigger is not automatically better — an oversized system short-cycles, controls humidity poorly, and wears faster — so confirm this capacity with a Manual J calculation that accounts for insulation, glazing, duct capacity, and climate.
Ideal for: larger single-family homes, open floor plans, and two-story houses with a substantial cooling and heating load.

Recommended Thermostat: Daikin One Touch
We recommend controlling this system with the Daikin One Touch Smart Thermostat (DTST-TOU-A). It is the nicer control and works better with the inverter equipment than the standard option, which matters most on a larger system running long, modulated cycles. The Goodman GTST Connected Thermostat (GTST-CW-WH-A) remains available.

Frequently Asked Questions
What home size does the 4-ton GZV9SA4810 system suit?
The 4-ton capacity is generally specified for larger single-family homes, open-concept spaces, and two-story properties with a heavier load. Always verify with a Manual J calculation, since oversizing hurts comfort and efficiency.
Why does this system use the larger AHVE60DP1300 air handler?
The 4-ton system is paired with the AHVE60DP1300 to supply the higher airflow larger homes require, giving the variable-speed blower headroom for even air distribution across bigger duct systems.
What electrical service does the 4-ton condenser require?
The GZV9SA4810 condenser needs a dedicated 208-230V, single-phase, 60 Hz circuit with a 34.4A minimum circuit ampacity and a 40A maximum breaker. The air handler is on its own circuit; a licensed electrician should size both.
Is this system rated 18 SEER2 because of the pairing?
Yes. The 18 SEER2 rating reflects the GZV9SA4810 matched with the AHVE60DP1300. Efficiency ratings are always tied to the specific condenser-and-air-handler combination.
Which thermostat do you recommend for the 4-ton system?
The Daikin One Touch DTST-TOU-A — it is nicer to use and performs better with the inverter system than the standard Goodman GTST-CW-WH-A, especially on a larger system.
