Goodman GSX13 Central Air Conditioners

Goodman GSX13 Air Conditioner Overview

Goodman markets the GSX13 air conditioner as an efficient and reliable product. This three-phase 13 SEER split-system series has models ranging in capacity from 1.5 to 5 tons and producing anywhere from 18,000 to 60,000 BTU/H.

The Smartcoil technology used to enhance the GSX13’s heat transfer capability incorporates refrigeration grade, rifled, 5 mm copper tubing and aluminum fins that reportedly provide a larger-than-average surface area. The coil is protected by a steel louvered guard. The GSX13 has sound-reducing features such as a quiet condenser fan system and a louvered sound control top to provide reduced operating noise.

Goodman produces the GSX13 with a louvered cabinet made with heavy-gauge galvanized steel. The cabinet has a side panel that allows access to the controls and provides enough space for accessories. The liquid and suction line service valves are made of brass, and the GSX13 features R-410A chlorine-free refrigerant.

"Good, solid A/C"

5.0 rating
Very Satisfied

Bought a complete system, 4 ton compressor, air handler, lines, etc. online and installed it myself, replacing an existing system. Everything worked perfectly and it has been installed for over one year. I chose a 13 SEER system because I expect it to be less complex and more reliable than higher-rated units. Even though it is only 13 SEER my electric bills dropped by 15% during the cooling season.

"Central AC as frigid as my ex-girlfriend"

4.0 rating
Somewhat Satisfied

I've owned this beast for nearly two years now and what can I say, I have very few complaints. It works just as advertised. It zaps every bit of moisture out of the air and brings ambient temperatures to what is set, keeping me and my family comfortable. The downside: it's loud to the point of being startling when it comes on (ruined rugs, but maybe it's the cat I should direct my anger towards), but it's a relatively trivial issue considering how comfortable it has kept my family, especially considering how humid the past couple summers have been. I would more than likely buy this brand again, so long as I can afford it.

"Goodman AC piece of junk"

1.0 rating
Very Unsatisfied

I purchased a 5 Ton Goodman AC unit on October 1, 2013 and the unit quit cooling after 2 years and 2 months . This occurred during the holidays in Florida with the temperature around 86 degrees during the day. I had to put my mattress in the living room under the ceiling fan to survive six (6) nights. I was able to get an AC technician on Monday after the holidays since no service calls were available. The technician had to order a new condenser coil which was under warranty ($900 if not under warranty). The system had a leak in the condenser coils which caused low Freon in the coils. I have to pay $846 for a diagnostic leak search, which includes a $500 to $600 Freon charge. I would not buy another Goodman AC unit if my life depended upon it. The unit is a piece of junk. Condenser coils lasted 2 years with a 5 year warranty on parts. Not a deal for all the inconvenience and discomfort; simply a piece of junk with no quality or pride of workmanship. I will tell everyone about my experience. The tech also said the Goodman product are poor quality. Just read the other reviews which of course I failed to do on the initial purchase. Never again. I hope this provides a review for caution for the next potential buyer…..buyer beware!

"Amazing Air Conditioner"

5.0 rating
Very Satisfied

I have had this air conditioner for a year and a half after our main air conditioner of 5 years stopped working completely and in a time that was mid-summer. So it was horrible for us and we were able to get this Goodman installed rather quickly for a very affordable price. So far we have done 2 checkups on it and it is running like a champ and had no issues at checkup. I have recommended Goodman to friends and family and I will recommend it to any one that is in need. What it breaks down to is a great price, a constant sturdy life, and a lot of head ache off of your mind. Plus the energy consumption isn't bad either. I think one of the worst things about losing an air conditioner is the fact that it usually happens in a time when you really don't need it to. So if you have issues then get Goodman.

"Dont blame Goodman for poor installation and service"

5.0 rating
Very Satisfied

After reading many of these reviews I am shocked by the description of the service and/or installation by the contractors used by the consumer. I am a commercial service technician with 20 years of in-depth experience in all aspects of the HVAC world. I only tell you this because it is obvious to me that the problem is with the service provider, not the product! In the majority of the reviews at least. I have been installing Goodman products for friends and family for well over a decade and have both a high efficiency furnace and heat pump in my own home. Goodman has one of the best warranties in the business if the equipment is registered to the original owner (and installed correctly). Out of likely one hundred pieces of Goodman equipment I have installed, I have had to only make repairs on roughly five in over a decade and they were all parts covered by warranty (never a compressor failure). Another thing that the average consumer does not realize is that Goodman uses the same compressors and components used by most all other brands, other than the few that manufacture their own parts like Trane and Lennox. Another piece of info for those that don't know is that Goodman is one of the only brands anyone and everyone can purchase online, unlike most other brands. This, of course, leads to a lot of Goodman equipment being installed incorrectly, thus casing premature failure or inadequate performance. The moral to the story here is do your homework before you hire any HVAC tech or contractor to do the work regardless of the brand you may choose. Most residential contractors use inexperienced technicians with little or no formal training whatsoever. And in most states residential techs don't need to be licensed in anything, unlike the commercial tech counterpart. If they were quality trained techs they would be working in the commercial side where the money is at. Don't get me wrong, I'm not saying there is no such thing as a quality residential tech, they are just few and far between. Fyi, I do not work for Goodman or have any affiliation with them! I'm just a satisfied consumer many times over that understands the real story and wanted to share my thoughts. I hope it helps somebody with the decision they need to make for themselves! Good luck 🙂

Other GSX13 Reviews

When a homeowner asks the experts on to comment on the quality of the GSX13 being installed into his new home, the contractors are split. Several say that this unit offers reliable performance, so long as it is properly installed. Others, however, point out that it is a budget unit and homeowners will get the minimal efficiency for which they’re paying. On a different thread, several contractors agree that this unit does have the quiet performance that the manufacturer promises.

GSX13 Warranty

The GSX13 come with a 10-year parts limited warranty, although homeowner are required to register the unit within 60 days of installation in order for this warranty to apply. Consumers should discuss additional coverage options with their Goodman dealer.
