When you need exceptional cooling in the summer and reliable heating in the winter, a Goodman heat pump can be a cornerstone of your HVAC system.

Buying a heat pump made by a former air conditioning contractor makes sense when you consider that the pump was designed to be easy to repair if it ever needed it and easy to install when you first get it.

The GSZ line of Goodman heat pumps has a mid-range noise factor, with models operating at between 72 and 76 decibels thanks to a quieter condenser fan manufactured with three blades that gives you good cooling with quieter air movement across the blades and coils. There are also noise control elements built in like a noise controlling top.

When professionally installed and anchored, they meet Florida hurricane standards so they will stay put even in high winds. That might not seem all that important, but in high wind weather, the last thing you want is to have your heat pump become a projectile into your house.


Each Goodman GSZ heat pump features aluminum fins with copper tubes in the condenser that help transfer heat effectively. This means less of the ozone-friendlier R-410A coolant needs to be used. Your heat pump’s coolant will also last longer than in other brands thanks to a Bi-flow Liquid Line drier that helps keep moisture from the outside air from damaging the coolant and the filter keeps dirt down.

A defrost system called SmartShift allows for effective conversion to defrosting when needed, and this, too, helps keep the noise levels down.

Some Goodman GSZ models also meet the government standards for being certified as Energy Star models, meaning they have been certified as being super energy efficient and also kind to the environment in terms of greenhouse gas emissions.

The steel cabinet is made from heavy galvanized steel for longevity, and louvers protect the coils from whatever life may throw at your heat pump. Baked enamel paint helps protect the steel from rain and corrosion.

A ten year parts warranty comes standard so long as your new heat pump is registered within 60 days of installation. Goodman also offers extended warranties for sale.

The GSZ line

GSZ16 Heat Pump

This heat pump delivers great cooling with a 16 SEER rating. It stands to reason that a company from Texas knows about hot weather, so it also stands to reason that these heat pumps will be a key part of your HVAC system in the summer. But more than that, the GSZ16 heat pump gives you 9.0 HSPF heating efficiency in the winter, keeping you and your home comfortable every season of the year.

The Copeland Two-Stage Ultratech Scroll Compressor means this heat pump moves from a low operating level to a higher one seamlessly and quietly. A high capacity muffler also helps keep the noise levels down.

Because these heat pumps are from a company founded by a former HVAC contractor, the service ports can even be accessed while the heat pump is running, making it easier for your repair technician to see exactly what is happening.

Testing of the paint using salt water means you have a paint job on your heat pump that will last for years to come.

GSZ14 Heat Pump

This heat pump is not quite as effective at cooling your home, but at 15 SEER it is still very efficient. It also delivers a 9 HSPF heating ratio thanks to a Copeland Two-Stage Ultratech Scroll Compressor and a copper tube with aluminum fins on the fan.

Like the GSZ16, the SmartShift technology enables smooth defrosting so your unit operates at peak efficiency. It’s also quiet, with that scroll compressor giving you quiet operation and energy efficient operation on even the hottest days.
