How to identify the worst furnace brand?

The brand of your furnace will depend on several different factors, so it is important to know all of them before buying.

Here are some tips for identifying the worst furnace brands.

1. Poor Quality Material:

This is the first thing that you have to look for when buying a furnace brand. You need to be sure that the material is good enough to ensure the proper functioning of the entire machine.

For instance, check if the manufacturer uses only high-quality materials for making the heat exchangers and other components.

Also, look at how long the furnace has been in operation. You need to make sure that it is not an old model.

2. Quality of installation:

A good installation is one where the technician does his job without making mistakes. It is important to ask the technician to provide a written quote before buying any brand.

This is because, no matter how good the brand is, if the technician installs it poorly, the furnace will most likely fail sooner than a brand with a good installation.

3. Unreliable Service Contract:

If the company you are getting the service from does not guarantee any type of service, it is better to find another one.

4. Reputation:

The reputation of a brand should be based on its performance over the last few years. If the brand has been around for decades, then chances are it has been reliable for a long time.

5. Poor Warranty:

Another red flag is the warranty period of the brand. The duration of the furnace warranty should be enough to cover any problems.

You do not want to buy a furnace brand that is sold at a low price but offers a poor warranty period.

List of Furnace Brands to Avoid in 2022

The below list is based on our research and users’ feedback. Now, check out the first name.

1. Burnham

Burnham-_worst_furnace

Burnham may not be the right choice for you if you are looking for a furnace. This brand claims to be durable, reasonable, and high-efficient. But this is not the consumers say.

Numerous people have complained that Burnham furnaces are not reliable. Many consumers said that there are leakage issues in their furnaces.

And while talking about customer service, a user said that if they don’t like what you are saying, they will block you, which is quite childish behavior, honestly.

Okay, so the next company that we will be telling you about is Buderus. It is known as one most famous companies that provide the best-quality furnaces.

Moreover, if you are looking for a furnace that is a little on the cheaper side, then Buderus is your brand.

However, you will need to stop there for a minute and read this review. Despite being reasonable, this manufacturer does have a lot of bad reviews.

Although the Buderus claims to provide high-quality furnaces, the consumers say otherwise. Various people have complained that their furnaces stopped working and they had to spend the 4 days in the cold.

Another thing you’ll be hearing out from people is that there is always a whistling sound whenever their furnace runs.  

Also, based on the consumer reviews, Buderus is rated 1.7, which justifies our point of calling it one of the least reliable furnace brands.

3. Ducane

As a part of the “Allied Air division of Lenox” series, Duane is one of those well-known brands for its reasonable furnaces. Apart from being inexpensive, Ducane tends to have a very competitive warranty.

However, the real question is why we have included this maker in our list then?

Okay, let us ask you what you would do if you’re given a furnace that needs repairing every other day because a new part stops working every day.

The worst part about Ducane is that if you want to replace any part, you won’t get those parts quickly. It isn’t easy to locate its parts.

A common complaint about Ducane furnaces is the whistling sound when they run.

Also, Ducane is rated 2.3 based on consumer reviews. So buy this brand only if you have lots and lots of money to waste on its everyday repair.

Still, wondering whether buy this product or not? Have a look at the overall drawbacks of this brand.

Reasons to Avoid

  • The unbearable smell while running the ac
  • Doesn’t stand behind their products

4. York

Unlike other companies, this here has more benefits. York is famous for its high-efficiency brands. York furnaces are chosen because of their temperature consistency and energy savings.

So many benefits, then why are we saying that this manufacturer is one of the least reliable? Well, that is mainly because of their customer service.

Some users had complained that their furnaces stopped working when they contacted the brand, but there was no response.

Customer service is one of the main things to consider when you are buying anything.

So, there is no need to purchase furnaces from this company if there is no one to help you with any problem with the furnace.

ArcoAire_Furnace

On our list of the furnace brands to avoid, the next manufacturer is Acroaire. Just like the brand mentioned above, this one also lacks supportive customer services.

Its warranty covers limited parts only. And the worst part is that they won’t remove or install them themselves.

Consumers have many things to say about this company, and after going through those comments, we have done it right to include this in our list.

A user said that the heat exchanger failed, causing a major flame that almost harmed her.

Another user complained that her furnace was shorted-circuit. Moreover, the furnaces also are of inferior quality, and the low-pressure switches fail often.

Arcoaire is rated 2.2 as per the consumer reviews. Our review is based on consumer feedback, so that is why we have decided to add this to our list.

Frigidaire_Furnace

Frigidaire is quite famous for its reliability and energy-efficient furnaces. However, the place where they need to work the most is the product quality.

People have complained that the furnaces are not of good quality. One said the blower fan of her furnace came off, and later on, her furnace started making sounds.

They also have a very poor warranty, and if in case any part of the furnace gets damaged, the warranty doesn’t cover that.

Another user said that the furnace was not strong enough to keep the house heated. Frigidaire is rated 2.9.

However, you’ll find that even if the users like one thing about these furnaces, there would be two things that they would complain about.

That is why customer dissatisfaction is one of the main reasons to call this brand the worse. Let’s have a look at some other reasons. 

Reasons to Avoid:

  • Vibrating sound
  • Furnace shuts down suddenly
  • The fan runs at low speed
  • The unit can’t keep up with the heat

The next company which we think is one of the worst furnace brands is Tempstar. Based on the consumer reviews, Tempstar has few of the poorest quality furnaces.

One user said that the blower motor in her furnace stopped working too often without any specific reason.

Another said that Tempstar has very poor customer service because she made many complaints, but none was answered. And the circuit board makes a buzzing sound while running.

This furnace brand is rated 2.5. So if you want to hear this sound and have a lot of money to waste, then go ahead; otherwise, stay away.

Weathering is famous for its unreliability and poor customer service.

One said that whenever it runs, only Lukewarm air is produced. Based on consumer reviews, this furnace brand is rated as 2.4.

Factors to Consider When Buying a Furance Brand

Furnace Buying guide

The decision to buy a new furnace can be hard to make, especially when there are so many factors you need to consider.

We have put together a list of questions to help you make an informed decision about which furnace is right for you.

The following are the most important factors to consider when purchasing a furnace brand. 

1. Where is the furnace going to be installed?

There are three main options:

  1. In the basement
  2. In the garage
  3. On the outside wall

Each of these locations has advantages and disadvantages. Let’s look at a few of them:

A) Basement Installs 

Advantages: 

A basement is a great location for a furnace because it is relatively cool down there. This is good if you have a heat pump with an outdoor condenser (most new homes do) because it will increase the efficiency of your heat pump. It also makes it easy to add a room to your home for extra living space.

Disadvantages: 

The first disadvantage of a basement furnace installation is that it can get very cold down there. If your furnace does not have a thermostat, then you could have a problem. In fact, if it gets cold enough, then your furnace might not even turn on!

Another disadvantage of a basement furnace is that it can be a little damp down there too. Moisture in the air can cause mold and mildew. If this is a problem for you, then you may want to consider an exterior wall installation.

B) Garage Installs

Advantages:

Installing a furnace in the garage is a great option if you have a carport or other type of garage that is insulated well. You also have access to a lot of power and a great location to add another floor to your house for extra living space.

Disadvantages: 

The main disadvantage of a garage furnace installation is that it can get very hot. The reason is that the exhaust from the furnace will not be able to escape out the back of the garage. This means that it will build up heat inside the garage, radiating all throughout the room where your furnace is located.

If you do not install an attic ventilation fan, then this could cause a serious problem with overheating and possibly a fire.

C) Exterior Wall Installs 

Advantages: 

Installing a furnace on the exterior wall of your house has many of the same advantages as a garage installation. The main advantage is that it will always be in the sun, which will help keep the room where the furnace is located relatively cool.

Disadvantage:

The main disadvantage of an exterior wall furnace is that it will always be exposed to the weather. This means that it will likely need to be changed more frequently than other types of installations.

Also, if your home is going to have very severe weather, then this option may not be viable for you.

2. What size residential furnace should I buy? 

There are three main choices: 10, 12, and 14 cubic feet per minute (cfm).

The first number is the heating capacity in British thermal units per hour (Btu/h), and it represents how much heat your furnace will give off in one hour.

  • A 10 cfm furnace will produce 10,000 Btu per hour.
  • A 12 cfm furnace will produce 12,000 Btu per hour and so on. A furnace that has a high Btu rating will run more efficiently over time and use less fuel.

3. How much money do you want to spend?

It is important to remember that a new furnace will almost certainly increase the value of your home.

However, there is a limit to how much an HVAC contractor will charge for a new furnace.

Besides the cost of the actual furnace, there is the cost of installation, the permit fees, and any other expenses that may arise. You should also consider the interest rate you can get on a home equity loan.

If you have decent credit and a solid down payment, then you could probably get a reasonable rate. If not, then you should consider other options.

4. How long do you plan to live in your home? 

If you plan to move within two to three years, you should definitely think about a budget-friendly option like a portable or stick-type furnace.

On the other hand, if you plan to stay put for a long time, you should seriously consider a more expensive option like a forced-air furnace.

5. What size house do you have? 

A smaller home will generally require a smaller furnace.

In brief, the rule of thumb is that a home with 3,000 square feet of living space will need approximately 1,000 BTUs per square foot of living space.

Therefore, a home with 6,000 square feet of living space will need approximately 2,000 BTUs per square foot of living space.

Keep in mind, though, that this is only a guide.

You should also consider any extra factors such as the age and condition of your home, how well it is insulated, and how much landscaping there is around your home.

6. How much heating do you use? 

This is especially important if you have a large home with a lot of rooms.

If you have a big home and hardly ever use the furnace or heat pump, then you should definitely consider an energy-efficient option.

On the other hand, if you use a lot of heat and the furnace or heat pump is working hard, then you should seriously consider a more powerful option.

7. How old is your home? 

The next thing you should consider is how old your home is.

If your home was built within the last ten years, you should definitely think about a high-efficiency option.

On the other hand, if your home was built 20 or 30 years ago, then you should seriously consider a more traditional option.

8. What is your home’s insulation rating? 

This will determine whether or not a forced-air furnace or an electric heat pump is a good option for you.

9. Types of Furnace to Buy

Types of Furnace

There are three main types of furnaces that you will encounter when you are doing home improvements. They are:

  • Gas Furnace
  • Electric Furnace
  • Kerosene Furnace

Let’s take a look at each of them.

# Gas Furnace

A gas furnace is the most common type of furnace you will find in homes. It works by using the combustion (burning) of gas to heat the home.

# Electric Furnace

An electric furnace works much the same way a gas furnace does, except it uses electricity instead of gas.

This means it doesn’t need small holes to let the gas flow into the furnace.

Instead, it has an electric element that heats up and turns into a very high temperature when electricity is passed through it. Electric furnaces are typically more efficient than gas furnaces.

However, they do have one drawback: They cannot be used with some types of fuel such as oil or kerosene.

Also, they are not very portable. This means if you ever decide to move, you will have to get rid of your electric furnace because it was designed to stay where it was originally installed.

# Kerosene Furnace

A kerosene furnace works like a regular old-fashioned wood-burning stove.

It has a firebox (the part of the stove that gets hot) which contains a grate. The grate has a fire on it which burns whatever you put on it.

The main difference between a kerosene furnace and a wood-burning stove is the way the heat is transferred from the fire to the home. A wood-burning stove uses radiation to transfer the heat.

This means the stove itself never gets very hot. Instead, the heat is transferred to the room through the walls, floors, and ceiling of your house.

A kerosene furnace uses convection to transfer heat. This means the firebox (and, therefore, the entire furnace) gets very hot.

Gas vs Electric Furnace | Which one should I Buy?

I personally prefer electric furnaces. They are much more efficient than gas and kerosene furnaces.

However, the choice is really up to you because they are all great heating systems. They all have their advantages and disadvantages. It just depends on how you plan to use the space you are heating. 

One thing all three types of furnaces have in common is they all have a blower that circulates the air inside the home.

The circulation of the air helps prevent stuff like radon gas from building up in the home.

2 Stage Furnace Disadvantages & Advantages

Many home heating systems have a two-stage furnace.

The first stage of the furnace is for preheating your home and the second one is for heating up your home.

There are advantages and disadvantages to each system.

The advantages of 2 stage heating systems include:

  • Increased efficiency (the first stage gives you an idea of when you should switch to the hotter unit)
  • More safety (a fan will switch on in case anything goes wrong with the first, smaller one)
  • And lower maintenance costs (you only need to buy one unit).

The disadvantages of 2 stage heating systems include:

  • A longer warm-up time (since the fan has to kick in after the smaller unit heats up)
  • A longer start-up time (the fan has to run for a while before the larger unit can get going)
  • More noise (it’s possible that the fan could be too noisy)
  • These systems could be higher energy costs (the two units need to run in tandem) 
  • And they create more carbon monoxide (CO) than one stage furnaces.

How Do You Choose? I recommend most people use a two-stage furnace if they can afford it. It’s just common sense.

Frequently Asked Questions

 How long will a Rheem furnace last?

On average they have a 13-year lifespan. However, if you do not maintain your furnace properly, it can last only about three to five years.

Is an electric furnace better than gas?

Yes, electric furnaces are more efficient and better for your home. The main reason electric furnaces are preferred over gas furnaces is that they cost less to run, saving you money in the long run.

What is the average life of a furnace?

A furnace has a lifespan that is determined by the type of fuel used. The life of a natural gas furnace is typically 10-12 years, while a propane furnace lasts 15-20 years.

Finding the best furnace is as important as staying away from furnaces that are nothing but a waste of money and time. We hope that after reading our review, now you can find the best furnaces.
