How Do Old Furnaces Differ From New Ones?

Are you thinking of upgrading your outdated heating system? Residential gas and oil furnaces have a lifespan of approximately 16 years. If your furnace is showing tell-tale signs of aging, such as poor fuel efficiency, frequent need for repairs, or uneven heat distribution, then it may be time to start shopping for a replacement.


The main difference between an old and new furnaces is efficiency. Modern furnaces waste less fuel when heating your home. They’re also engineered to better direct heat into your house rather than out the chimney.

Fewer Repair Costs

While installing a new furnace can be costly, it eliminates the need to invest in costly and unexpected repairs. Why sink money into an outdated heating system when you could reduce your energy bills with a new one?


When you install a new heating system, you may also opt to set up individual heating zones. This enables you to remedy uneven heat distribution or tailor settings to please individual household members.

Evaluating the Numbers

A professional heating contractor can help you compare your current furnace to a wide range of new ones. He or she can also calculate your furnace’s annual fuel utilization efficiency to determine your potential cost savings and reduced environmental impact.


Older furnaces are more likely to have faulty electrical components as well as excess carbon monoxide output. A seasoned HVAC professional can examine your existing heating system to determine whether or not it poses a potential threat. Often, the cost of replacing worn or damaged parts outweighs the cost of a replacement.

Multi-Stage Heating

Older systems run at one speed. Meanwhile, many new systems offer multiple heating stages. This enables a heating system to reduce its overall effort during times of lower output. This puts less stress on the overall system and enables it to run more efficiently.

Can Furnaces Run Without Filters?

It is easy to see that filters are associated with air quality. Many believe that they prevent dust from spreading around the house. Moreover, they say that filters collect allergens such as animal dander and pollen, and might even prevent the circulation of germs that can cause illnesses. However, not everybody suffers from allergies, asthma, or illnesses that would necessitate perfect air quality in the house.

If you are among the lucky ones who do not face allergies, you may not think too much about having a filter. Actually, such persons, particularly those who do not want to deal with the task of changing filters all the time, have questioned whether it is possible to run a furnace without using a filter. Read on to find out the answer to this question.

What Is the True Purpose of a Filter?

A common misconception that many people have is the assumption that the filter is only in place to protect someone’s health. Actually, the filter was originally designed to prevent debris from ruining the furnace itself. Incoming debris and other items could easily pummel the heating system and cause permanent damage, or get stuck in the blower fan, thus jamming the motor.

Not being aware of such information is what makes some persons think that they can be able to run their furnace without using a filter, clearly, this will cause severe harm. The following are some important reasons why it is unwise to run your heater without a filter:

1. You Will Be Putting Your Heating System at Risk

Without a filter, the furnace can easily break down because of the debris lodged in the blower fan. Moreover, the gradual accumulation of damaging particles will lead to the early demise of your system.

2. You Are Risking the Health of Those in the Home

You may not be affected by the indoor air quality, but allergens can easily develop and contaminants in the house such as chemicals and germs that are not safe to inhale can affect your health and other occupants in the home. Don’t forget to replace the filter regularly.
