Rheem Introduction

Since brothers Richard and Donald Rheem founded the company in 1925, Rheem has become a leader in heating and cooling products in North America and globally. In fact, they’re currently the largest manufacturer of water heating products in North America. The company has an ambitious goal to achieve zero waste by 2025 and seems to be on the way to achieving it. 

A few impressive numbers include four factories with no waste to landfills and more than 2.5 million pounds of packaging eliminated per year. Sustainable products translate to long-term savings for the homeowner, even if you’re not concerned with the environment. 

Rheem also has a history of innovation and firsts, being the first company to use scroll compressors throughout their lineup (1994). In 1997, they became the first company with a remote 14 SEER condenser. In 2009, they became the first company with a hybrid heat pump and water heater.

Goodman Introduction

Goodman is a much younger company, having first opened its doors in 1975 as a manufacturer of flexible ducts and plastic blade registers. Harold V. Goodman was an HVAC dealer with a dream of providing affordable HVAC equipment to households in the US and beyond. 

With the closing of Janitrol in 1982, Goodman had the opportunity to enter the market, buying the equipment they needed to start supplying central air conditioners and heat pumps to the market. In 2012, Goodman was purchased by Japan’s Daikin Industries but remained an independent subsidiary. 

Goodman is currently moving all its operations to its 4.1 million square foot facility near Houston, Texas. The Daikin Texas Technology Park is the single most significant investment made by Daikin in its history. 

Like Rheem, Goodman is also committed to the environment, holding the ISO 14001 certification from Det Norske Veritas (DNV). Their building is LEED (Leadership in Energy and Environmental Design) Gold certified.

What Rheem Does Better Than Goodman

Rheem has been in the HVAC business for a long time and has grown with the technology, becoming an industry innovator. Rheem has a much more extensive product range, including air conditioners, water heaters, furnaces, and even pool heaters. 

Rheem focuses on new technology and sustainability, so they produce some of the ACs with the highest SEER ratings and constantly improve the product performance with new “degrees of innovation.” Anyone looking for the latest technology and willing to try new ideas can look toward Rheem for their HVAC equipment. 

Rheem offers decent warranties on all their equipment. Still, these warranties remain in line with the industry standard unless you buy grey-market equipment from the internet with a five-minute warranty and install it yourself.

Both Rheem and Goodman have committed themselves to sustainability and supplying a greener product. Still, Rheem appears to have mastered the concept early, with Goodman trailing behind in SEER ratings and manufacturing processes. Rheem has a better research department and is more willing to apply new ideas and approaches to their manufacturing and design methods.

Rheem products give you the best that modern technology has to offer. The company is known for supplying good quality products. Sometimes they may be a little too eager to employ new ideas, so some products don’t live up to expectations. If you’re willing to pay a little extra for quality and innovation, Rheem is the brand to look at. 

What Goodman Does Better Than Rheem

The two areas where Goodman trumps Rheem is customer service and price. Harold Goodman’s original vision was to supply affordable HVAC equipment to American households. The company has held true to its original ideals. You can count on a Goodman unit to cost less than its equivalent from any other well-known manufacturer. 

Goodman has partially achieved this by centralizing all aspects of their operation in the Daikin Texas Technology Park, saving money and making communication between departments easier. They have also achieved economy by sacrificing innovation and relying on tried and tested technologies. As a result, their ACs generally lag behind competitors in some aspects. 

The other area where Goodman excels, and this can also be attributed to the company’s founding principles, is customer service. By centralizing their operations, including parts, manufacturing, and customer service, the departments can communicate better and resolve any issues that may arise rapidly. 

As we mentioned previously, Goodman has committed to sustainability and environmental awareness. The company is ISO 14001 certified, meaning they have processes to manage and mitigate environmental impact. Their offices also have LEED Gold certification.

Like Rheem, Goodman offers a 10-year warranty on their units, they also provide a 10-year warranty on labor if you use an approved contractor.

Essentially, the warranty covers the parts and the installation for 10 years, which is better than the industry standard. 

Goldman offers a no-frills HVAC with a proven track record and excellent customer service with the best warranty in the industry. If you’re happy with not having the latest technology, but prefer a unit with a proven track record and a lower price tag, then Goldman products fit the bill. 

Rheem vs Goodman: Similarities

We’ve taken a close look at where each brand shines over the other. Let’s investigate some similarities.

Environmental Concerns

The first similarity you notice between Rheem and Goodman isn’t their products but both company’s commitment to environmental sustainability. Both companies have made an effort to use more sustainable materials in the manufacturing process and manage their global impact on the environment. Each has taken a different approach to the problem with similar results. 

Price Range

The HVAC units manufactured by these two companies also show some similarities. Although Goodman is generally cheaper, their premium products fall into the same price range as Rheem. The Rheem units have a slightly higher SEER rating. 


Both companies offer similar warranties on parts and manufacturing defects (10 years). However, Goodman includes a labor warranty if you use an approved installer. We feel that the labor warranty is Goodman’s attempt to minimize reputational damage from shoddy installations resulting in premature equipment failure and additional repair costs.

Both companies have suffered some degree of reputational damage from poorly installed HVAC units. The availability of their products on the market has led to some installers tempting customers by offering low installation quotes but providing substandard workmanship.

US Manufacturing 

Both Goodman and Rheem manufacture their own products in the United States. Rheem does have some factories outside the United States, but their main manufacturing base remains at home. These companies were started in America and still keep to their roots, even after being bought by Japanese groups. 


You can expect either of these companies to supply you with a good quality product, made in the United States, for a reasonable price compared to their nearest competitors. Both manufacturers fill the mid-range niche in the HVAC market, with Goodman concentrating on the lower portion of the range and Rheem filling the upper part with many of their products intersecting in the areas of performance, reliability, and cost.

Goodman supplies low-priced ACs to the market but also backs them up with more generous warranties than Rheem. The customer service from Goodman is also excellent, so anyone looking for a budget system with decent guarantees and customer service should look to Goodman HVAC products.

Rheem incorporates more technology into their products, achieving better SEER ratings. Still, they also cost more, and the customer service can’t match Goodman’s service. Anybody looking for high-efficiency units and willing to pay the extra would be well-served looking at Rheem’s offerings.
