The Goodman GSZ13 is a relatively inexpensive and inefficient heat pump, with a single compressor. It earns energy efficiency ratings of 13 SEER (cooling) and 7.8 HSPF (heating).
The heating and cooling capacity for this model both range from 18,000 to 60,000 BTU/h (i.e. from 1.5 to 5 tons). Sound output ranges from 71 to 76 dB.
This model uses R-410A refrigerant (a.k.a. Puron). It thus compares favorably to the GSH13 (a Goodman model with similar efficiency), which uses R-22 (a type of refrigerant known for damaging the Earth’s ozone layer).
Goodman’s manual for the GSZ13 provides detailed information about the unit’s performance at different temperatures, so you can assess its likely operation in your climate.
I started having problems with my heat pump One year after I received it because we are now a coil went out feon leak out,and I was not able to get parts to repair .the warranty lasted five years which did me no good 10 years If the unit was registered in which I didn't know.one bad nightmare. I wouldn't recommend Goodman heat pump to a enemy
"Do not depend on Goodman to honor the warranty"
The unit itself is okay but if something goes wrong do not depend on Goodman the live up to the paper they gave you about a 5 or 10 year warranty. I had our unit installed on may 31, 2013. installer/dealer said its really good–man. It has a 10 year warranty on all parts. Its what I have on my house, etc etc. I came home Saturday, July 22, 2017 it was 85 degrees and rising upstairs at 2:30 pm. No a/C. Checked everything, kids and wife screaming. Called some a/c people. It is July in Tennessee on a late hot hot Saturday. Everyone is overloaded. Found a guy who would come out and be here at 7:00 pm. He fixed it. A capacitor was bad. OK . Called Goodman Monday to get my money back for the capacitor. Oh no, our guy must come to your house, find the trouble remove the part, take it to our supplier get a new one, come back and put it in. But lady it's 95 degrees, it's Saturday, I gotta get it fixed. Thems the rules sorry. What if I take the bad part to your authorized supplier? Nope, thank ain't in the rules. Beware of Goodman.

If you live near salt water do not buy Goodman! Our heating and cooling company recommended Goodman to us 4 years ago and we installed 2 units. We are second row from the ocean (about 1/8 mile away from water). We get no direct spray and units are on the back of the house, elevated and protected. We just had to replace the line drier, it was completely rusted out and all the Freon leaked out. The second unit is almost as bad and the technician said it will have to also be replaced soon, total cost over $500! Our last units which were not Goodman lasted for 12 years, this tells me that Goodman uses inferior materials.

"Goodman Heat Pump"
One of the more inexpensive heat pumps that I have previously owned. I like how little electricity that it uses. You can tell that it is not the top of the line in heat pumps, but it works great for me. Never had to do any repairs on this. I would definitely consider buying another one like it, or just like it because this heat pump has served all of my needs very efficiently. I actually think that this is an excellent value for the price that I payed for this heat pump. Would recommend it for anyone who doesn't have wads of money to spend on it, and needs one.
"I have owned the unit about a year and a half to two years"
Compressors don't last very long if it costs me $800.00 every one and a half to two years. Highest upkeep I know of.
Reviewers on hvac-talk.com are dismissive of the GSZ13. They don�t like Goodman generally, and consider the GSZ13 to be overly inefficient and error-prone. They also suggest that the initially low cost will be overwhelmed by necessary maintenance. In general, they prefer Trane and other brands. (They remind consumers that Goodman and Amana are now the same company.)
Users at gardenweb.com seem to hold similar opinions, suggesting that consumers could pay a little more for their heat pump and get substantially better results.
Folks at doityourself.com are harsh in their reviews of the GSZ13 and anyone willing to install it, suggesting that these units are more trouble than they were worth. These reviewers generally prefer Lennox and Trane.

This model has a 10-year limited parts warranty. It's only good for the original owner and at the original location. It does not cover damage due to bad installation, human intervention or natural disasters. If a part is broken, you can send it back to Goodman and they'll send you a new one (although you will pay for shipping).
