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 purchased my home brand new (new construction) with a Goodman heat pump/air handler. It's now 3 1/2 years later and the heat pump quit working a few weeks ago. My wife and I have our 3rd girl due soon so I attempted to figure the problem out with no luck so I broke down and called a local HVAC company to come see what is going on and how much to fix. The technician put refrigerant in (due to the problem seeming to be that it had zero refrigerant) and after filling it with a small amount, he noticed that there was a leak. He explained that he was going to use a meter and see if he could locate the leak; however, if it was the inside coil needing to be replaced then it would cost around $1500 to repair, and if it turned out to be the outside coil then it was a $1600 dollar repair. He found leaks in both inside and outside coils and said it would be wise to look into having the entire system replaced and to look around for prices on systems, installation, etc., and it would be around $6000 for a new system. Well, this was all I needed one month before my third daughter is due to come. To the people at Goodman, I do appreciate your system lasting me and my family less than four years. I also hope your families have good things like this happen to you.
"Great for the price, fantastic value"
Overall this is a fantastic pump. My last one was okay, it had some issues but I replaced it and got this. I have had it about a full year going now. I like pretty much everything about it, from the quality to how well it works, and the price was great. I did dislike the setup of it compared to the other brands but it is one minor gripe. I would still recommend it compared to others, as I have had no reason to replace it because it runs and works flawlessly. It is one of the better products I have ever had.
"True model #GSZ130361BC"
Only had the unit for 2 and 1/2 years. The coil already went out. The company that put it in states that Goodman isn't paying for the coil; the company that put it in is having to pay for the part and shipping. It will cost me about $200.00 for labor and $60.00 a pound for the coolant to put back in there. This is not a good company. Buyer beware!
"Don't buy a Wade Jurney home that has a Goodman heating pump."
If you purchase a Wade Jurney home, then your house comes with a Goodman heating pump that is horrible and barely works. I was in my brand new home for barely a year and the Goodman heat pump went out. If I don't have an issue during the winter then it's summer and vice versa. I contacted Wade Jurney and they sent someone during the warranty period. What I can't understand is why Wade Jurney continues to purchase Goodman heat pumping pumps knowing they have all these complaints. Every single homeowner in my new community has had issues with their Goodman heating pumps.
"Unsatisfied with unit"
I've had my unit for 3 years, and it stopped working. The repairman said there was a leak somewhere and the unit lost all the Freon so it doesn't work. It will cost me over $600 to have this repair fixed. I would not recommend this unit to anyone.
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.
