Your car's AC just breathed its last cold breath. Now three brand names dominate every parts search: UAC, GPD, and Four Seasons. Here is the short answer. Four Seasons wins on warranty length, at 2 years or 24,000 miles on compressors. GPD wins on stated durability testing and everyday pricing. UAC wins on catalog breadth and affordability. No single brand wins every category, and this guide shows why, using each brand's own published terms.
Who Actually Makes These Three Brands?
None of these three names are one-person garage operations. Each sits inside a larger company with its own warranty department and manufacturing footprint. That backstory explains why the warranty terms differ so much.
| Brand | Parent company | Founded | Headquarters |
|---|---|---|---|
| UAC | Universal Air Conditioner, Inc. | 1988 | Mansfield, Texas |
| GPD | Global Parts Distributors, LLC | 1974 (as Auto Air of Macon) | Macon, Georgia |
| Four Seasons | Standard Motor Products, Inc. (NYSE: SMP) | 1919 | Long Island City, New York |
UAC (Universal Air Conditioner)
UAC started in 1988 as a straightforward parts distributor. By 1995, UAC began developing its own compressor and component programs. It moved beyond simple reselling, according to UAC's published company profile. In November 2024, private equity firm Halifax Group made its first institutional investment in UAC. Co-CEOs Francisco Coll and Sophia Coll Crowley stayed on to run the company, per deal reporting from Privsource.
GPD (Global Parts Distributors)
GPD has the most hands-on origin story of the three. It began in 1974 as Auto Air of Macon, a small AC installation and repair shop. The company grew into a national aftermarket AC supplier, according to trade coverage from Vehicle Service Pros. GPD's parent, Global Temperature Control, also owns the Santech brand. Both operate as separate labels under investors that include Omega Group and Owner Resource Group.
Four Seasons
Four Seasons is a division of Standard Motor Products (SMP). SMP is a public company dating to 1919, per Wikipedia's company summary, with 2025 revenue near $1.79 billion. Four Seasons calls itself the largest aftermarket mobile climate control parts supplier in the world. It also claims the title of largest compressor remanufacturer, per its official product documentation.
Warranty Terms Compared
Warranty length is the single biggest documented difference between these three brands. It also decides what happens if the replacement compressor fails in month 14.
| Brand | Standard compressor warranty | Commercial or fleet use |
|---|---|---|
| UAC | 1 year from date of purchase | Not separately published |
| GPD | Typically 12 months, per retailer listings | Not separately published |
| Four Seasons | 2 years / 24,000 miles | 12 months on commercial, heavy-duty, or fleet use |
UAC's terms come straight from its published warranty policy. Four Seasons' terms appear consistently across its official listings, including its warranty page on Parts Avatar. GPD does not publish one master warranty document online. Most retailers list a 12-month manufacturer warranty per part instead.
The fine print that matters most: all three brands require the same prep work. Replace the accumulator or drier, replace the orifice tube or expansion valve, and flush the system. Skip any one step, and the claim gets denied, regardless of brand.
Certifications and Testing Claims
Marketing copy loves the word "quality." Here is what each brand actually documents in writing.
- UAC cites ISO/TS 16949 quality standards and describes its own factory auditing and in-house validation process across its catalog listings.
- Four Seasons manufactures in ISO 9001:2015-certified facilities, and its premium remanufactured compressors carry a stated validation equivalent to 100,000 miles of use.
- GPD states that every new compressor design passes a 200,000-mile durability test and gets 100% leak tested with helium spectrometers, according to GPD's own part specification sheets. We could not locate a published ISO certificate number for GPD, unlike UAC and Four Seasons.
If a formal ISO certificate matters to you, ask your GPD supplier for documentation directly. UAC and Four Seasons publish theirs; GPD does not, at least not publicly.
Where the Compressors Are Actually Built
"Aftermarket" almost never means "made domestically," and none of these three brands are an exception.
- UAC: primarily manufactured in Asia, per the brand's own warranty documentation and product country-of-origin fields.
- GPD: product listings most often show China as the country of origin, though individual buyers have reported compressors boxed as South Korean-made.
- Four Seasons: country-of-origin data varies by part number, with Mexico appearing most frequently for remanufactured units, alongside Malaysia and the United States on other listings.
The Plot Twist: Some "Different" Compressors Are the Same Part
Here is the part most comparison articles skip. Cross-reference catalogs reveal the pattern. Many UAC, GPD, and Four Seasons compressors share the same underlying casting and design. They simply carry different labels and warranty terms.
| Four Seasons part | GPD equivalent | UAC equivalent |
|---|---|---|
| 158347 | 6512288 / 7512288 | CO11157C |
| 168663 | 7512953 / 7512955 | CO29174Z |
The source is FindItParts' interchange data. In plain terms, the physical compressor is often nearly identical. What you're really buying is the warranty label sitting on top of it.
What Mechanics and DIYers Actually Say
Forum threads are not lab data, so treat these as color rather than proof. Still, patterns show up across independent automotive communities.
- On Bob Is The Oil Guy, one user's UAC compressor was still running a year after installation in a Ford Escape.
- Another user on the same thread received a GPD compressor sourced from South Korea that worked fine, though other kit components arrived damaged in shipping.
- On GMT Nation, a forum moderator reported good experiences with GPD's China-made compressors, while describing weaker feedback on remanufactured Four Seasons units in that specific thread.
- Several posters on both forums noted that shipping damage, not the compressor itself, caused most of their reported failures.
Read those as individual, unverified reports, not a controlled study. No independent lab comparison of these three brands appears to exist publicly.
Price: What You Are Really Paying For
Compressor prices swing heavily by vehicle application, so a single "Brand X is cheaper" number would be misleading. One pattern does hold across retailers. GPD and UAC new compressors generally list at or below Four Seasons new-unit pricing. Four Seasons remanufactured units often price closer to GPD and UAC instead.
Given how often parts overlap, ask which warranty backs the casting longest. That question matters more than the lowest sticker price.
How to Choose the Right Brand for Your Situation
| Your situation | Reasonable pick | Why |
|---|---|---|
| Tight budget, older vehicle | GPD or UAC | Lower typical pricing, documented testing claims from GPD |
| Want the longest safety net | Four Seasons (new) | 2-year / 24,000-mile compressor warranty |
| Fleet or commercial vehicle | Confirm terms in writing first | Four Seasons drops to 12 months for commercial use; ask GPD and UAC sellers directly, since this is not always published |
| Flipping or reselling the car | GPD or UAC | Longevity matters less than upfront cost |
Whichever brand you choose, follow the flush-and-replace prerequisites from the warranty section above. That single step affects your claim more than the brand name on the box.
Final Verdict
There is no single universal winner here, and any article claiming otherwise is guessing. On paper, Four Seasons wins on warranty length and scale, backed by a $1.79 billion parent company. GPD wins on documented testing claims and competitive pricing, backed by AC-specialist roots dating to 1974. UAC wins on catalog breadth and accessible pricing, with a straightforward one-year warranty.
Match the brand to your priority, not the other way around. If warranty length is your top concern, Four Seasons is the documented choice. If price and availability matter most, compare GPD and UAC listings for your exact vehicle before you decide.
Frequently Asked Questions
Is Four Seasons better than UAC?
Four Seasons carries a longer compressor warranty, at 2 years or 24,000 miles, against UAC's 1-year term. UAC counters with a wider catalog and generally lower prices. The better brand depends on whether warranty length or upfront cost matters more to you.
Does GPD make good AC compressors?
GPD states that its compressors are 100% leak tested with helium spectrometers. Every new design also runs through a 200,000-mile durability test, according to retailer specification sheets. Community forum feedback is mixed, but many DIYers describe GPD as a solid budget performer.
Why do UAC, GPD, and Four Seasons parts sometimes share a part number?
Aftermarket suppliers often reuse the same OE-pattern casting under their own brand and part number. Cross-reference catalogs regularly show identical compressor designs sold under all three brand names.
What voids an aftermarket AC compressor warranty?
All three brands share the same rule. You must replace the accumulator or drier, the orifice tube or expansion valve, and flush the system. Skipping any of these steps is the most common reason a warranty claim gets denied.
Are these compressors made in the USA?
Rarely as a complete unit. UAC and GPD compressors are primarily sourced from Asia. Four Seasons units mix Mexican, Malaysian, and US manufacturing, depending on the part number.
Which brand should I buy for a daily driver?
If warranty length matters most, Four Seasons is the documented leader with its 2-year compressor coverage. If price matters most, compare GPD and UAC listings for your exact vehicle, since pricing swings by application.
