Having a reliable central heating system like a furnace is essential for withstanding harsh winters or living in locations where it’s consistently cold. When selecting a furnace, it’s crucial to know which brands to avoid and what features to prioritize. In this post, we’ll provide an overview of the top worst-performing furnace brands and offer insights on how to identify red flags that indicate a brand is not reliable.

To help you make an informed decision, we’ve compiled a list of five most reliable furnace brands, including their best-selling models. These include Rheem’s Classic Plus Series, American Standard’s Platinum 80, Carrier’s Infinity Series, Goodman’s Bronze Comfort System Series, and KeepRite’s ProComfort G9MX. When shopping for a new furnace, there are several key factors to consider. First, think about the size of your home and the heat output you need.

Next, consider air filtration systems, speed blowers, and heat exchangers. You should also look for zoned heating capabilities and high AFUE ratings. Additionally, don’t forget to check the warranty offered by each brand. The cost of a new furnace can vary greatly depending on the size, features, and brand you choose. In this post, we’ll provide an overview of what you can expect to pay for a brand-new furnace and answer frequently asked questions about different brands.

What red flags help you identify furnace brands to avoid?

When it comes to furnaces, knowing the warning signs of a lemon brand is crucial for avoiding early replacements and costly repairs. A few key indicators can help you identify subpar furnace brands that might not meet your needs or expectations. One obvious red flag is the use of cheap materials that break down quickly with minimal maintenance. Inferior brands may also compromise on indoor climate control, offering single-speed fans and stage burners that fail to deliver on their promises.

Furthermore, short warranties – typically under 12 years – can be a sign of a furnace brand’s lack of confidence in its product’s performance and longevity. Additionally, unusual sounds or noises from your furnace could indicate defective circuit boards or overworked components, which may lead to costly repairs down the line.

7 worst furnace brands to avoid

While some may claim that any furnace priced under $600 is subpar, regardless of the manufacturer, it’s essential to consider a more nuanced approach when evaluating furnaces. To provide a more comprehensive guide, I’ve compiled a list of brands to avoid based on various indicators, including customer satisfaction ratings, surveys, brand reports, and anecdotal evidence from prominent review platforms.



A well-known home furnace brand has faced backlash due to its abbreviated warranties, which have led to a decline in customer satisfaction. Many customers have expressed frustration over premature damages occurring outside the warranty period, forcing them to bear the costs of repairs. Furthermore, some users have reported that newer models exhibit subpar performance, characterized by slow heating and uneven heat distribution.

Additionally, the brand’s products are often priced higher than comparable alternatives, exacerbating the issue. To make matters worse, customer service has also been criticized for being inadequate.



While affordability is certainly one of its draws, this budget-friendly furnace brand’s performance falls short of expectations. According to brand surveys, it earns a mediocre 2.8 out of 5 rating, while customer satisfaction stands at just 43% as of 2020. The primary culprit behind these lackluster ratings is the high failure rate of its products. Many customers report that their first costly repair with this brand occurs within a surprisingly short three-year span.

Some have even noted that the unit’s heating capabilities are so subpar, it can stop working altogether in just five years. Unfortunately, the quality and performance of these furnaces simply don’t measure up to industry standards.



While Ducane may have its loyal fans who prefer it over other budget-friendly brands, it’s not without its criticisms. The brand’s shortcomings lie in its relatively short warranty, subpar performance, and questionable component quality – which often results in premature failures. Additionally, some customers have reported unusual noises emanating from the furnace when it’s in operation, making for an uncomfortable indoor experience.

These issues collectively contribute to a customer satisfaction rating of just 38%, highlighting the need for improvement.



A well-established brand in the realm of appliances such as refrigerators and ovens, this company surprisingly falls short when it comes to furnaces. A major drawback of their models is the inconsistent heat quality, which often fails to deliver even heating, particularly during extremely low temperatures. Furthermore, the customer service provided by this brand receives poor ratings. In fact, its overall performance rating for furnaces is a disappointing 3.

4 out of 5, a significant letdown considering the brand’s reputation and popularity. Moreover, customers’ reviews regarding energy efficiency are mixed, suggesting that the product is not living up to expectations. This disparity in quality casts doubt on the brand’s ability to deliver consistent performance across its entire range of products.



The brand with the highest failure rate is a notable mention, as customers have reported issues with premature repairs, with some furnaces needing replacement within just one year of purchase. Furthermore, heating performance has been subpar, with small parts prone to breaking down shortly after installation. The dismal 2.8 out of 5 rating from brand surveys suggests that taking a chance on this brand may not be the best decision.

Moreover, their customer service leaves much to be desired, and the 10-year warranty’s effectiveness is questionable, adding to the overall uncertainty.




The reliability of this brand is the primary concern. Its affordability has led to a reputation for costly repairs, with some customers experiencing issues within just three years. Furthermore, the heating performance leaves much to be desired, as it can be noisy and even cause anxiety at times. Additionally, energy efficiency appears to be an area where this brand falls short. Installation is also reported to be challenging, which may explain why contractors are hesitant to recommend it.

Overall, its rating of 2 out of 3 suggests that it’s not a top choice for many consumers.

What should I look for when buying a furnace?

Regardless of experience with furnaces, it’s crucial to develop a thorough understanding of the essential factors to consider when purchasing one. To ensure a successful and stress-free shopping experience, the following key considerations should be at the forefront of your decision-making process.

#1. Size

The efficiency of a furnace ultimately hinges on selecting the optimal size for your dwelling. A unit that’s undersized will struggle to provide consistent heat across all areas, leading to uneven performance. Conversely, a furnace that’s oversized for the space will result in increased installation costs and reduced energy efficiency.

To avoid these pitfalls, it’s essential to consult with a reliable contractor who can assess your home’s specific needs and recommend a furnace size that strikes the perfect balance.

#2. Air filtration

While many top-notch furnace manufacturers include air filtration systems as standard features, these components can prove particularly valuable for individuals grappling with respiratory issues such as asthma. As air circulates through the heating system, these filters efficiently capture dust particles, providing a healthier breathing environment for those who need it most.

#3. Speed blowers

A reliable home furnace is one that offers multiple speed settings for its blower. This feature allows homeowners to precisely control the temperature within their living space, as high heat is not always necessary. In fact, a seven-speed blower is a significant upgrade from traditional two- or three-speed models, providing greater flexibility and comfort.

#4. Heat output

One of the most impressive features of this product is its ability to adjust the temperature in real-time, much like a heat sensor would. As the room reaches the perfect temperature for optimal comfort, the device automatically adjusts the heat level to ensure you’re always feeling cozy. This intelligent feature often comes packaged with multi-speed blowers, allowing for greater control over your heating needs.

#5. Heat exchanger

In modern furnaces, a crucial component is the heat exchanger, responsible for dissipating heat from burned gas. Top-notch furnace manufacturers often equip their products with a supplementary heat exchanger, designed to maximize thermal recovery and extract even more usable heat. The incorporation of this secondary heat exchange mechanism not only enhances the overall efficiency of the furnace system but also contributes significantly to its energy-saving potential.

#6. Zoned heating

The premier characteristic of this system is its ability to regulate distinct temperature zones within a residence, catering to varying room requirements. While this sophisticated feature is most effectively utilized in larger dwellings or expansive homes, it ultimately offers unparalleled comfort and control.

#7. AFUE rating

When evaluating a furnace’s energy efficiency, one crucial factor to consider is its Average Fuel Utilization Efficiency (AFUE) rating. This metric measures how effectively the unit converts gas into heat, providing insight into its overall fuel efficiency. In general, furnaces with AFUE ratings ranging from 80% to 85% are considered cost-efficient and worthy of consideration. Any ratings below this threshold may not be as economical in the long run.

#8. Warranty

When investing in a premium furnace, it’s essential to consider not only its performance but also the manufacturer’s commitment to customer service. A comprehensive warranty is a crucial aspect of any high-end furnace purchase, with many premium options boasting protection periods of 10 years or more. However, even the best warranties are only as good as the company’s ability to uphold their promises.

For this reason, it’s vital to research and select a brand that has a reputation for delivering excellent customer service, ensuring that any issues or concerns can be addressed promptly and efficiently.

How much is a brand-new furnace?

When it comes to purchasing a premium brand-new furnace, you can expect to spend anywhere from $2000 to $6000. However, this price point doesn’t take into account the cost of installation and labor, which can add significant expense to your overall bill. Furthermore, the size, brand, and type of furnace you choose will also impact the final cost.

In reality, a full furnace system can set you back anywhere from $3700 to $30,000, making it essential to factor these additional costs into your budget.


While our initial list provided valuable insights into top-rated furnace brands, it’s possible that your specific needs may require further consideration of other notable brands or key details not previously mentioned. To enhance the overall understanding of what to expect from different furnace manufacturers, we’ve compiled a list of frequently asked questions that address common concerns and provide additional context for making an informed decision.

Is Rheem a good furnace brand?

The company’s sterling reputation stems from a trifecta of factors: consistently impressive furnace performance, comprehensive warranties, and a product lineup that caters to diverse budgets. While they offer a range of furnace models at varying price points, each one boasts commendable features that have contributed to their enduring appeal.

Is York a good furnace brand?

While York has garnered mixed reviews, one common criticism is its reliability issues, with some consumers reporting that units are not well constructed and prone to costly repairs shortly after installation. However, the brand also boasts an impressive AFUE rating and efficiency, making it a consideration for those seeking a high-performance heating solution.

Is Goodman furnace a good brand?

When it comes to midrange furnaces, Goodman is a well-known brand that offers a good balance between quality and affordability. While some homeowners may view Goodman as a budget-friendly option, others may see it as a reliable choice for those who are willing to put in the effort to maintain and repair their furnace themselves.

The reputation of Goodman furnaces can be a bit mixed. Some consumers report that they’re less reliable than high-end brands, while others have had no issues at all.

Ultimately, what you get from a Goodman furnace will depend on what you’re willing to put into it. If you’re looking for a budget-friendly option and don’t mind doing your own maintenance and repairs, then a Goodman furnace could be a good choice for you.

Is Amana a good furnace brand?

With a legacy spanning over six decades, Amana has established itself as a reputable manufacturer of furnaces, offering premium quality products at a mid-range price point. When compared to top-tier brands like Goodman and Carrier, Amana’s furnaces have demonstrated exceptional efficiency and reliability, earning them a strong reputation among customers.

Additionally, the comprehensive warranty coverage provided by Amana is a significant selling point, further solidifying their position as a trustworthy brand in the market.

Is Daikin furnace a good brand?

For those seeking a trustworthy brand with minimal maintenance costs over the course of ten years, this manufacturer stands out as a top recommendation. Their furnaces are designed for larger spaces, boasting well-constructed models that provide comprehensive coverage. Priced affordably from entry-level to mid-range options, they offer an economical solution.

In terms of efficiency and reliability, their performance is comparable to Trane and Carrier, making them a strong contender in the market.

Is Payne a good furnace brand?

While Payne has garnered a mixed bag of reviews as a furnace manufacturer, the brand still warrants consideration. While efficiency may not be its strongest suit, with Consumer Reports placing it 2-4% behind top-rated brands, Payne’s reasonable price range and solid customer ratings earn it a spot among good furnace brands. The Better Business Bureau’s ‘B’ rating also suggests that the company is committed to fair business practices.

What brand of furnace is the best quality?

When seeking top-tier furnace brands that consistently deliver high-quality products, it’s essential to consider the following industry leaders. By no means an exhaustive list, this selection of well-regarded brands includes Bryant, Carrier, Daikin, Goodman, HEIL, Maytag, Rheem, and Trane.

What furnace brand and model is the quietest?

While some may argue that another model has taken its place, the Carrier Infinity 98 remains an industry leader. With a long-standing reputation for being the quietest brand and model on the market, it’s no surprise that it also excels in terms of energy efficiency and overall reliability.

How long do furnace warranties typically last?

When it comes to premium brands, a standard warranty clause often includes a 10-year guarantee on limited parts and a 20-year commitment to the heat exchanger. This extended coverage is particularly crucial given the heat exchanger’s critical role in the furnace. It’s essential to choose a manufacturer that stands behind their product with a comprehensive warranty, especially for this vital component.

Is it cheaper to replace the furnace and AC together?

While it may seem logical that replacing older components with newer ones would reduce repair needs in the long run, there’s a catch – the upfront cost of replacement can be steep. Moreover, contractors often advise against replacing all components at once, suggesting instead that homeowners have a professional assessment done before making any decisions.

How long should a furnace system run daily?

When operating in scorching temperatures or well-insulated environments, furnaces typically require around 10-15 minutes per cycle. The actual number of cycles needed daily depends on the size of the space and desired temperature level. For precise calculations, we recommend consulting your product manual or seeking guidance from a professional.

What should not be stored in a furnace room?

To ensure utmost safety, it’s crucial to keep potential fire hazards such as flammable materials (paper, cardboard) and combustible substances (chemicals) at a distance from the furnace room. Moreover, consider investing in a reliable smoke or carbon monoxide detector to provide an added layer of protection against potential threats.

What is the most efficient furnace on the market?

When it comes to selecting the most efficient furnace for your specific situation, there’s no one-size-fits-all answer. However, there are several top-notch brands worth considering if you’re in the market for a new unit. These brands, including Carrier, Lennox, and Rheem, offer a range of high-efficiency furnace models that cater to diverse needs.

Is Lennox furnace a good brand?

Established as a reputable force in the heating sector, Lennox boasts an extensive portfolio of high-performance furnace options. Whether you’re searching for a model tailored to your specific requirements or seeking a reliable solution, Lennox’s array of high-efficiency furnaces is designed to cater to diverse needs. Furthermore, their products are renowned for their exceptional quality and longevity.

Is Trane worth the extra money?

While Trane furnaces may carry a higher price tag than other brands, their superior quality and performance make them well worth the investment. For instance, Trane furnaces have been known to last significantly longer than those from other manufacturers, reducing the need for frequent replacements. Additionally, they are renowned for their reliability, minimizing the likelihood of unexpected breakdowns.

Furthermore, Trane furnaces tend to be more energy-efficient, resulting in lower utility bills and a greater return on your investment. If you’re seeking a high-quality furnace that will provide years of dependable service, a Trane is an excellent choice.
