Core features of the Goodman GVZC20 heat pump
Like mini-split systems, heat pumps have an outdoor compressor and an indoor air handler. The Goodman GVZC20 features only an outdoor unit, and you must purchase its indoor component separately.
The manufacturer doesn’t provide any information regarding the maximum number of zones this heat pump can have, so you need to consult with the HVAC technician you hire to install the system whether or not it is possible to split the unit’s output into several zones.
The line sets are also not included in the offer, and you must find compatible suction and liquid lines before starting the installation process.
Despite all of these shortcomings, the Goodman GVZC20 is still one of the best heat pumps on the market because it can remain functional for more than a decade with little to no upkeep.

Under ideal conditions, a 36,000 BTU heat pump should regulate the room temperature in a 1,500sq/ft area. However, the heating capacities of these systems are largely reliant on the outdoor temperature unless you pair the unit with a gas furnace.
The manufacturer doesn’t provide the maximum number of air handlers you can connect to the Goodman GVZC20, so you need to do additional research to find out if it is possible to split the unit’s output into multiple zones.
The brand offers a wide range of indoor air handlers, and you need to consult with the licensed dealer and the HVAC contractor about their compatibility with the Goodman GVCZ20 heat pump.
It is worth noting that factors that are not related to its features, such as the average annual temperature in the region where you live or the number of windows and doors in the space where the heat pump will be installed, can affect the coverage range of this unit.
Hiring an HVAC technician might help you estimate the size of a heat pump system you need to properly cool or heat a specific area. Read our guide to the best 5-ton heat pumps if you need a unit capable of regulating temperature in spaces larger than 3,000sq/ft.
Properties of the compressor
As the heart of a heat pump, the compressor plays a key role in the system’s performance, and its features determine how efficient the entire system is going to be. The Goodman GVCZ20 has galvanized steel cabinet that protects the compressor and other components from all types of weather.
It has a two-tone gray powder paint finish, and it grants you top and side access to the parts of the outdoor unit. The Goodman GVCZ20 is equipped with a variable speed swing compressor that allows you to increase or decrease the system’s output incrementally.
The unit’s cabinet also contains a built-in compressor crankcase heater that maintains the refrigerant’s temperature above the coldest part of the system.
In addition, the GVCZ20 features sensors that monitor the ambient and coil temperature to ensure the smooth operation of this component.
This Goodman’s heat pump is pre-charged with enough refrigerant to allow you to install the indoor air handler 15-feet away from the outdoor compressor. Our guide to the best 4-ton heat pumps might help you find the right cooling and heating system for your home.
Cooling and heating efficiency ratings
The power consumption of whole-house cooling and heating systems like the Goodman GVCZ20 is one of the most important factors determining its efficiency. With the 21 SEER and 10 HSPF ratings, the GVCZ20 is the brand’s most energy-efficient heat pump model.
Even though they’re Energy Star certified like the GVCZ20 model, all other Goodman’s heat pumps have SEER ratings lower than 20. High seasonal cooling and heating ratings indicate that the GVCZ isn’t going to significantly increase your household’s power consumption.
It’s worth adding that the heat pump’s power consumption changes depending on the current weather conditions. The unit’s operating range spans from 115F to -5F, but its low-temperature performance might not be sufficient to heat the 1,500sq/ft area.
Go through our guide to the best 2-ton heat pumps if you’re looking for a suitable cooling and heating solution for a space smaller than 1,200sq/ft.
Airflow control options
The heat pump’s maximum airflow depends on how powerful its outdoor component is. The manufacturer doesn’t include the information about the system’s maximum airflow output in the product description or data about the indoor air distribution.
The unit utilizes an electronically communicated compressor motor that allows you to set the airflow output anywhere within the 0% to 100% range. Also, the model’s compressor features copper coil tubing and aluminum fins that broaden the heat absorption area.
The GVCZ20 has a filter drier that helps the system to absorb moisture and get rid of air contaminants. Check out our guide to best replacement coils to find out more about different types of coils you can encounter in heat pump systems.
The cabinet of this Goodman’s model features a high-capacity muffler that dampens the vibration the compressor generates while operational. Moreover, a foam compressor blanket reduces the amount of noise this unit makes.
It is worth adding that the heat pump makes more noise in the heating mode than it does in the cooling mode. The GVCZ20 generates between 56dB and 74dB of noise in the cooling mode, while the least amount of noise it can make while operating in the heating mode is 69dB.
This heat pump will make 78dB of noise if you use the maximum of its heating capabilities.
Besides allowing you to adjust the heat pump’s settings through an app, The ComfortBridge™ technology enables you to initiate a diagnostics session if the system isn’t working properly. The unit also features lights that help HVAC technicians to detect the problems the heat pump encounters.
This Goodman’s model is equipped with SmartShift technology that guarantees a smooth transition into the defrost mode and prevents ice accumulation on the compressor. Also, this unit is compliant with the ETL North American safety standards.
Purchasing just the Goodman GVZC20 isn’t enough to install the system because you must also get an indoor unit, a thermostat, and various other accessories this heat pump needs to function normally. This unit doesn’t come with an installation kit, although it does contain an installation manual.
Ideally, a professional HVAC technician should help you calculate the heat pump size you need, guide you through the selection process, and install the system for you.
Also, you should bear in mind that you cannot use a line set longer than 15 feet with the Goodman GVZC20 unless you add more refrigerant to the system. Read our guide to the best HVAC gauges to find out how to charge a heat pump.
