Buyer’s Guide

When purchasing a proper furnace, avoiding the worst brands is not enough. To choose from the recommended brands, you need to know the important considerations. Look out for these when you purchase a furnace. The furnace brand comparison chart would give you a better understanding of the best furnaces.

What red flags help you to identify the furnace brands to avoid?

As many new brands and models are being introduced to the market, it is difficult to find reviews about all of them. So if you are planning to buy a new furnace, here are some of the major points that should be focused on to find what furnace brands should be avoided. 

Cheap Material

It is easy to notice the cheap build of a furnace from its material and construction of components. Low-quality brands often have material that breaks easily after few maintenance checks. They would also have to be subjected to expensive repairs in a few years of usage. 

Indoor Climate Control

Furnaces with single-speed fans and single-stage burners are not efficient in serving the purpose. Therefore, make sure to avoid inferior furnaces with these features.

Short Warranties

When the manufacturers are aware of the fact that their products’ performance wouldn’t last that long, they would most likely issue a short-term warranty. This is done to back up the limited longevity of furnaces. Therefore, do not settle for any product of warranty less than 12 years. Never purchase a furnace with a 5-year warranty as it is a clear sign of a low-quality product.

Abnormal Sounds

Noisy furnaces would mean that the circuit boards are defective or that the single fans have been overworked. This again is a sign of a worse furnace brand.

Costly Repairs

If you purchase a bad brand of furnace, then you would most likely have to face expensive repairs in three years or less after purchase. This is another negative impact of furnaces that should be avoided.

What Should You Look For When Buying A Furnace?

Here are the major factors that you need to consider when buying a furnace. Make sure to use these tips to find the perfect model for your requirements. However, do not get driven away by additional features as some of them might be useless depending on your requirements.

Pick the Right Size

You need to pick the right size of furnace for your home. It might not be able to perform well if the wrong size is picked. Smaller sizes for larger spaces might create uneven heat distribution, while larger furnaces in smaller spaces would cause high expenditure and energy inefficiency. So request your contractor to assess the right size of furnace for you.

Air Filtration

Pre-installed air filtration systems are available in most good furnace brands. It works in a way to collect dust particles that circulate through the heating system. It is most suitable for people with respiratory problems like asthma. 

Variable Speed Blowers

Having various speed blowers in the furnace helps to regulate the internal temperature. As very high heat is not required in homes, it is ideal to have a seven-speed blower than two or three-speed blowers.

Variable Heat Output

Multi-speed blowers have this special feature that can adjust the temperature when it senses that the room has required the required heat level. This feature may not be present in all furnace brands. It would deliver more heat with increased efficiency by altering the heat output automatically. You can even customize the level of heat required for your needs.

Heat Exchanger

A heat exchanger draws heat from the burned heat and increases the energy efficiency of the furnace. Most good furnace brands have this secondary heat exchanger made of stainless steel and protected.

Zoned Heating

The zoned heating feature is available in high-end furnaces. It channels various levels of heating to different rooms in the house. This feature might be useful for larger spaces and homes. However, having this feature might lead to frequent repairing of the system.

High AFUE Rating

The Average Fuel Utilization Efficiency measures the efficiency of the furnace gas being converted to heat. When choosing a furnace, it should have a rating of at least 80% to 85%. Choosing below this is not cost-efficient.


A premium furnace would mostly have a warranty of 10 years or more. Having a warranty less than this might be questionable. It is also necessary to go for a brand with good customer support to get support for the warranty.

How Much is a Brand-New Furnace?

The average price of a premium furnace would range between $2000 and $6000. With installation and labor costs included, this would range from $3700 to $30,000. This would slightly change, depending on the size, brand, and type of the furnace.

How to Avoid Cheap Installation?

Cheap installation is almost as bad as a cheap furnace. If it is not installed correctly, the effects would last throughout the years and even impact the efficiency and durability. Therefore, to ensure proper installation, you may need to know these ways.

  1. Read the gas furnace buying guides and brands reviews to learn more about the brands you consider buying.
  2. Get installation estimates from 3 or more local dealers who are qualified as furnace contractors in your area.
  3. Check for the North American Technician Excellence program (NATE) certification of the installers or whether they are factory trained.
  4. Make sure to review the online ratings and feedback of the relevant furnace company.
  5. Cheaper estimates should be rejected as it might mean that the installers are new and inexperienced in the matter. They might even be planning to cut corners or perhaps even have less work due to bad reputations. So it is better to avoid these possibilities.
  6. Choose the best option depending on the choices you have. Go for a reputed installer that offers the service at a reasonable cost.
