COSMO is a California-based value-premium brand best known for pro-style range hoods, gas ranges, and built-in kitchen appliances that cost less than the big legacy luxury names. It suits remodelers who want a stainless, commercial-looking kitchen on a mid-range budget and who are comfortable researching service and installation. It is a weaker fit for buyers who want the longest-established service network or the lowest risk. This guide covers the brand, its collections, eight real listings, how it compares with rivals, and what to check before you buy.

A Short History and What the Brand Stands For
COSMO describes its mission as making luxury appliances accessible to more households, and it says its products are sold in more than 100 stores across the United States and Canada. Its own pages state that it sets product specifications, develops designs, and manages customer service and warranty programs from California, while manufacturing is handled by international partners. We could not verify a founding year or parent company from official or independent pages, so we leave those out rather than guess.
The brand’s reputation is split by product. Range hoods get the most positive feedback: owners praise suction, styling, and fairly simple installation, and the models carry permanent baffle filters you can wash. Ranges, ovens, and microwaves draw more caution. One review blog warns that the odds of reliability or support problems are higher than with long-established premium makers, and reports early oven and microwave failures. Retail reviews on the brand’s own listings tend to skew positive, so read a spread of sources and weigh service access before committing to a full suite.
COSMO Product-Line Map
| Line | What it is | Best for |
|---|---|---|
| Range hoods (Vista, Haven, Lumin, Delta) | Wall-mount, under-cabinet, island, and insert hoods from about 380 to 500 CFM in the listings | Budget-friendly ventilation with a pro-style look |
| Gas ranges (Nebula, Haven, Stellar, Vista) | 24-, 30-, 36-, and 48-inch ranges, many convertible to propane, some with air fry | Pro-style cooking on a mid-range budget |
| Cooktops and wall ovens | Gas and electric cooktops; 24- and 30-inch single, double, and combination wall ovens | Custom built-in layouts |
| Refrigeration and dishwashers | Counter-depth French door refrigerators and tall-tub 24-inch dishwashers | Matching a stainless suite |
| Microwaves | Over-the-range, countertop, and built-in drawer microwaves | Completing a package |
Note that one collection name can appear across several product types, for example Haven range hoods, Haven ranges, and Haven microwave drawers, which makes it easier to build a matching suite.
Best Sellers and Picks From COSMO
These are popular COSMO listings across the main categories. Specs come from the listing titles; anything missing there is described as not listed. Large and built-in products need cutout, power, gas, and venting checks before you buy.
COSMO COS-63175S: 30-Inch Vista Ducted Wall-Mount Range Hood, 380 CFM
30 in. Vista Coll 380 CFM Ducted Wall Mount Range Hood LED, Stainless Steel | Cosmo COS-63175S Soft TouchControls, 3 Fan Speeds, Permanent Dishwasher-Safe Baffle Filters, Backdraft Damper
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 30-inch stainless wall-mount hood rated at 380 CFM with soft-touch controls, three fan speeds, LED lighting, permanent dishwasher-safe baffle filters, and a backdraft damper. It is the kind of hood that gives a kitchen a focal point at a modest cost. The limitation is airflow: 380 CFM suits a typical electric or modest gas cooktop but may be light for a big gas range, and the title does not list the noise level. Match the CFM to your cooking and duct size.
COSMO COS-QS75: 30-Inch Haven Under-Cabinet Range Hood, 500 CFM
30 in. Haven Coll 500 CFM Ducted Under Cabinet Range Hood, LED, Stainless | Cosmo COS-QS75 Soft Touch Controls, Wireless Remote, Dual Motor, Permanent Dishwasher-Safe Baffle Filters, 4 Fan Speeds
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 30-inch under-cabinet hood with 500 CFM, a dual motor, four fan speeds, soft-touch controls, a wireless remote, and permanent baffle filters. The higher airflow makes it a better partner for heavier searing and gas cooking than the Vista wall-mount. The limitation is fit: under-cabinet hoods need a cabinet to mount under and a duct route, and the title does not list the noise at high speed. Plan the duct and check the height above the cooktop.
COSMO COS-965AGC: 36-Inch Nebula Gas Range With Convection, 4.4 Cu. Ft.
36 in. Nebula Coll 4.4 cu ft 5 Burner Gas Range Convection, Stainless Steel | Cosmo COS-965AGC Oven Fan Circulation, Cast Iron Grates, Digital Display with Timer, Metal Knobs, Liquid Propane Convertible
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 36-inch gas range with five burners, a 4.4 cu. ft. convection oven, cast-iron grates, a digital display with timer, metal knobs, and conversion to liquid propane. Convertibility helps if you move between natural gas and propane. The limitation is range reliability: reviews of the brand are more cautious about ranges than hoods, so confirm warranty and service before buying. The title does not list burner BTU ratings.
COSMO COS-EPGR304: 30-Inch Haven Gas Range, 4.8 Cu. Ft. Convection
30 in. Haven Coll 4.8 cu ft 5 Burner Gas Range, Convection, Stainless Steel | Cosmo COS-EPGR304 Convection Oven, Knob LED Indicators, Mirror Finished Knobs, Storage Drawer, Liquid Propane Convertible
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A standard-width 30-inch gas range with five burners, a 4.8 cu. ft. convection oven, knob LED indicators, mirror-finished knobs, a storage drawer, and propane conversion. A 30-inch width fits the standard opening in most kitchens, which makes it a simpler replacement than 36-inch models. The limitation is the same as other COSMO ranges: service access and long-term durability should be checked. Burner output is not listed in the title.
COSMO COS-DIS6502: 24-Inch Lumin Built-In Dishwasher, Tall Tub
24 in. Lumin Coll Built-In Top Control Tall Tub Dishwasher, Stainless Steel | Cosmo COS-DIS6502 Built-In Design, Fingerprint Resistant, Heated Dry Function, Advanced Sanitize Technology, Three Racks
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 24-inch stainless top-control dishwasher with a tall tub, three racks, a fingerprint-resistant finish, heated dry, and sanitize technology. Three racks add flexibility for cutlery and small items. The limitation is noise: the title does not list the dBA rating, which matters in open-plan homes. A built-in also needs water, drain, and electrical connections and professional installation in many cases.
COSMO COS-FDR223GWSS: 36-Inch Lumin Counter-Depth French Door Refrigerator, 22.4 Cu. Ft.
36 in. Lumin Coll 22.4 cu. ft. French Door Refrigerator, Stainless Steel | Cosmo COS-FDR223GWSS Counter-Depth, Water Dispenser, Ice Maker, Digital Touch Temperature Controls, Door Alarm Feature
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 36-inch counter-depth French door refrigerator in stainless steel with a water dispenser, ice maker, digital touch temperature controls, and a door alarm. Counter-depth styling sits flush with cabinets for a built-in look. The limitation is capacity: 22.4 cu. ft. is smaller than many full-depth units, and the title does not list freezer layout or ice maker output. Confirm width, doorway, and water line before delivery.
COSMO C106SIX-PT: 24-Inch Lumin Electric Wall Oven With True Convection
24 in. Lumin Coll 2.9 cu ft Electric Wall Oven, True Convection, Stainless | Cosmo C106SIX-PT 8 Oven Functions, Digital Touch Controls, Interior Lighting, Child Safety Lock, Drip Pan Included
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 24-inch single electric wall oven with 2.9 cu. ft. of capacity, true convection, eight oven functions, digital touch controls, interior lighting, a child safety lock, and a drip pan. A 24-inch width suits small kitchens and apartments. The limitation is capacity: 2.9 cu. ft. holds less than a 30-inch wall oven, and the title does not list self-clean, so check the spec sheet. It needs a proper cutout and a hardwired circuit.
COSMO COS-12MWDSS-NH: 24-Inch Haven Built-In Microwave Drawer, 1.2 Cu. Ft.
24 in. Haven Coll 1.2 cu. ft. Built-in Microwave Drawer, Stainless Steel | Cosmo COS-12MWDSS-NH Touch Controls, 11 Power Levels, 1000W, Child Lock Function, Defrost Functions, Automatic Presets
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
A 24-inch built-in microwave drawer with 1.2 cu. ft. of capacity, 1000W, touch controls, 11 power levels, a child lock, defrost functions, and automatic presets. Drawers are comfortable to reach and keep counters clear. The limitation is the cutout: drawers need a purpose-built opening and a trim approach, and the title does not give the interior height. The “NH” in the code suggests a no-handle version, so check which handle option you get.
How COSMO Compares With Rivals
| Brand | Strength | Where COSMO differs |
|---|---|---|
| ZLINE | Pro-style ranges and hoods | Comparable style; check each brand’s range models side by side |
| Thor | Pro-style ranges at value prices | Similar target buyer; compare warranty and service access |
| GE and Frigidaire | Large service networks and many price tiers | COSMO is less established but cheaper for pro looks |
| Bosch | Dishwashers and built-ins | COSMO covers more pro-style cooking at lower prices |

Buying Tips for COSMO
Reading a model code
COSMO codes follow COS- plus a pattern. In the titles, hood codes such as COS-63175S and COS-QS75 pair the hood with a size or style number, and the trailing S often means stainless. Range codes such as COS-965AGC and COS-EPGR304 use a number for width: 965 suggests 36 inches and 304 suggests 30 inches, while EPGR names the Haven range family. Microwave drawers end in NH when sold without a handle in the listing. This is a reading of the listings, not an official decoder.
Which line to choose
- Start with a range hood if you want the lowest-risk way to try the brand; it is the best-liked category.
- Choose a 30-inch range for a standard opening and a 36-inch range only if you have a wider cutout.
- Pick a 500 CFM hood for heavy gas cooking and a 380 CFM hood for lighter use.
- Buy a full suite only if you have confirmed a repair option in your area.
Warranty and service
The company runs warranty registration and a customer support hub, but we did not find a published term on the pages we read. Ask the seller for the exact term, keep your invoice, and note where a technician would come from. Gas appliances should be installed by a qualified installer who checks the gas line and leak safety.
Common complaints to plan around
- Reliability concerns raised for ranges, ovens, and microwaves in some reviews.
- Hoods that stick out further than the old unit or that are louder at high speed.
- Needing a new outlet for hoods that plug in.
- Gas conversion kits and installation steps that owners overlook.
Ventilation sizing and gas safety notes
| Question | Guideline to check | Why it matters |
|---|---|---|
| How much airflow? | Match CFM to cooktop output and cooking style; heavier searing and gas need more | Under-sized hoods leave smoke and grease in the kitchen |
| Ducted or ductless? | Ducted hoods vent outside; ductless hoods recirculate through filters | Ducted removes moisture and combustion byproducts better |
| Duct run | Shorter, straighter ducts perform best | Long runs and elbows cut real airflow |
| Gas type | Confirm natural gas or propane and the conversion kit | Wrong orifices cause poor flames and safety risks |
Who should skip COSMO
Skip COSMO if you want the largest service network, the longest brand track record, or a maintenance-free range for decades. In those cases, a well-established brand may be safer even if it costs more.
Sample COSMO Combinations From the Listings Above
- Standard remodel: the 30-inch Haven gas range with the 30-inch Haven under-cabinet hood. Both share a collection name, and the 500 CFM hood pairs sensibly with a five-burner gas range. Confirm duct size and hood height above the cooktop.
- Statement cooking wall: the 36-inch Nebula gas range with the 30-inch Vista wall-mount hood. Check that the hood is at least as wide as the cooking surface; a 30-inch hood over a 36-inch range is under-sized for capture.
- Small-space kitchen: the 24-inch Lumin wall oven, the 24-inch Haven microwave drawer, and the 24-inch Lumin dishwasher. All three share the same 24-inch width family, which helps cabinets line up.
- Stainless suite: add the 36-inch counter-depth French door refrigerator to any of the above, and confirm that its width and door swing fit your layout.
Mixing collections is possible, but handle styles and knob finishes differ between Vista, Haven, and Lumin, so view the products side by side before ordering. Retail photos can hide small differences in trim and color, and a printed spec sheet is more reliable than a thumbnail. Finally, ask whether the seller accepts returns on large items; delivery damage and wrong dimensions are the most common reasons a suite arrives incomplete.
Frequently Asked Questions
Where is COSMO headquartered?
The company says it is headquartered in Chino, California, where it manages design, customer service, and warranty. Manufacturing is done by international partners.
Are COSMO range hoods good?
Owners generally praise the suction, look, and ease of installation, with complaints about size and noise on some models. They are the brand’s best-liked category.
Are COSMO ranges reliable?
Opinions are more cautious. Some review blogs warn about higher risk than long-established makers, so check the warranty and local service before buying.
Do COSMO ranges convert to propane?
Several listings above mention liquid propane convertibility. Confirm the kit is included and have a qualified installer do the conversion.
What is the difference between Vista, Haven, and Lumin?
They are collection names that group matching styles. Vista and Haven appear on hoods and ranges, while Lumin appears on hoods, a dishwasher, a wall oven, and a refrigerator. Check each listing for exact features.
Does COSMO sell a full kitchen package?
The company offers matching appliances in the same collections, and some retailers sell packages. Verify that all pieces fit your cutouts and power supply.
Is a 380 CFM hood enough?
For light to moderate cooking on a standard cooktop it can be, but heavy gas cooking benefits from more airflow and a short, straight duct.
Can I install a COSMO appliance myself?
Hoods and countertop items are manageable for experienced DIYers, but hardwired ovens and gas ranges should be installed by qualified professionals.
Does a ducted hood need a backdraft damper?
A damper keeps outside air, pests, and odors from coming back down the duct when the fan is off. The Vista hood listed above mentions one, and most ducted installations benefit from it.
Wrap-Up
COSMO gives a pro-style look at a friendlier price, and its range hoods are the easiest entry point. Treat ranges, ovens, and microwaves with a bit more homework on warranty and service. If you are still deciding, compare it with the established brands in our other guides before you commit. Whatever you choose, write down the model numbers, keep the invoices, photograph the installation, and register each product, because those small steps make any later warranty claim faster and less stressful.
