What to Know: Is it Possible to Upgrade My Furnace?


A furnace is an important part of a home’s heating system. It is a mechanical device that converts fuel into heat throughout the home. A furnace typically consists of a heating element, a blower, and a combustion chamber or flue. In most cases, the furnace is powered by natural gas or electricity.

In today’s article, let’s take a closer look at furnaces and how to upgrade it to become more efficient. Here’s what you need to know:

How Does a Furnace Work?

Furnaces are an essential part of home heating systems in many parts of the world. They are responsible for keeping our homes warm and comfortable, especially in the colder months. But how exactly does a furnace work? 

The burner is at the heart of a furnace, which generates heat. The burner is powered by natural gas, propane, or oil and ignited by an electrical spark. The heat generated is transferred to a heat exchanger as the fuel is burned. The heat exchanger is a metal chamber that absorbs the heat and transfers it to the air passing through it.

Can I Upgrade My Furnace to be More Efficient? 

The short answer is, of course! If you want to save money on your heating bills, upgrading your furnace to a more efficient model may be a great option. Several benefits to upgrading your furnace include lower energy costs, improved air quality, and greater comfort in your home. 

What to Consider Before Upgrading

When upgrading your furnace, you should also consider the type of fuel it uses. If you have an older furnace, it may be using an outdated fuel source. You try fuel oil or natural gas and switch to a newer, more efficient fuel source, such as propane or electricity. 

Additionally, newer, high-efficiency furnaces use advanced technology to reduce emissions and improve air quality in your home. 

In addition to fuel type, you should also consider the size of your furnace. If your current furnace is too small for your home, it may need to be fixed to heat the space adequately. In this case, you may need to upgrade to a larger, higher-efficiency furnace. 

On the other hand, if your current furnace is too large for your home, it may be using more energy than necessary, leading to higher energy costs. 

Furnace Parts You Can Upgrade

1. Furnace Filters: The furnace filter is the first defence against dust, dirt, and other airborne particles. Over time, the filter becomes clogged, reducing airflow and causing your furnace to work harder. Replacing the filter regularly will help your furnace run more efficiently and extend its life.

2. Blower Motor: The motor is responsible for circulating air through your home. As it ages, it can become less efficient and use more energy. Upgrading to a newer and more efficient model will help your furnace run better and save you money on your energy bills.

3. Heat Exchanger: The heat exchanger is part of your furnace that produces heat. Over time, it can become worn and inefficient. Replacing it with a newer, more efficient model will help your furnace run better and last longer.

4. Ignition Systems: The ignition system starts your furnace. Over time, it can become worn and inefficient. Upgrading to a newer, more reliable model will help your furnace start more quickly and use less energy.

5. Thermostat: The thermostat is responsible for controlling the temperature in your home. Upgrading to a newer, more advanced model can help you save energy and money by allowing you to program your furnace to run at specific times

The Bottom Line

Regular maintenance and upgrades can improve the efficiency of your furnace and reduce energy consumption. Upgrading your furnace can help reduce energy costs, enhance air quality and comfort, and reduce repair costs.

When in doubt, a qualified HVAC technician can help you make the best decision for your home. Investing in a reliable and efficient furnace can help you save money in the long run and make your home more comfortable and healthy for those living in it.

Why Your Furnace Isn’t Blowing Hot Air and How to Fix It


Furnaces are essential components of any home heating system. Without a furnace, many homes could not maintain comfortable temperatures during the cold winter months. A furnace creates hot air by burning a fuel source such as natural gas or propane. This hot air is distributed throughout the house, providing warmth and comfort for the occupants.

The importance of a furnace cannot be overstated. It is essential for keeping a home warm and cozy in the winter, and it can have a huge impact on energy efficiency and utility bills. A well-maintained furnace can help reduce energy consumption and costs, while a poorly maintained furnace can cause costly repairs or result in an inefficient system.

Unfortunately, furnaces are prone to breakdowns, and one of the most common problems is a lack of hot air. If this is the problem you’re facing today, you’re in luck. We’ll tackle the common causes of this issue and how you can fix them:

1. Dirty Filters

Have you ever thought about when you last changed the air filter in your furnace? If you can’t remember or it’s been a long time, that may be the cause of any problems you’re having. Your furnace needs a clean filter to disperse warm air properly, but unfortunately, dust, dirt, and other allergens accumulate on them over time, causing them to get blocked.

If your furnace is emitting cold air, you’ll need to inspect the air filter. Remove it and hold it to the light to check if any light passes through. If not, it’s time to get a new one. Generally, the filter should be changed every six months, but if your house is busy with people and animals, it’s best to swap it out every three weeks.

2. Blown Out Pilot Light

A gas furnace has a pilot light that needs to stay lit for the heater to work properly. The light can be blown out in certain circumstances, such as maintenance or an emergency by the gas company. If this happens, the furnace will not provide heat and needs to be re-lit.

If the pilot light on your furnace is out, you can try to re-light it yourself using the instructions in the furnace’s manual. If it keeps going out repeatedly, check if any dust or debris is blocking the connection and clean it if necessary. If that doesn’t help, ensure the gas supply line is open, as it may have been closed if the furnace wasn’t used during the summer.

If none of the other solutions have worked to fix your problem, then you may need to get a new thermocouple. This might be something you could do on your own. However, it requires special care and attention to ensure it is fixed and installed properly, so it is best to get a professional to do this job.

3. Wrong Thermostat Settings

Before reaching out to a professional, double-check the settings on your thermostat. It may be something as simple as a change in the temperature or a need for new batteries that keep your furnace from producing hot air.

To fix this, the main thing to check is the fan setting. If it is set to “on,” it will run constantly. This is why you may feel cool air coming through. To resolve this, switch it from “on” to “auto.” Generally, this will lead to your furnace pushing out heat once more.

If the problem persists, check the thermostat to ensure it is set to the desired temperature. If the thermostat is set to a lower temperature than the current temperature in your house, that could be the reason for the discrepancy.


These are the common causes of a furnace failing to provide the hot air you need. So, if you’re experiencing any of them, act right away! Of course, there could be other causes of the problem that we haven’t talked about, but if it seems like nothing you do is working, reach out to a professional. They can quickly uncover the problem and ensure that your furnace is, once again, providing the hot air you need!

Everything You Need to Know About Furnace Limit Switches


The furnace limit switch is an important safety component in any residential or commercial HVAC system. Given this, it’s in your best interest to be as informed as possible about this component to avoid any issues or problems down the line. To make things easier for you, here’s everything you need to know about furnace limit switches.

What is a Furnace Limit Switch?

The furnace limit switch is designed to shut off the furnace if the temperature inside the furnace gets too high. Without a limit switch, your furnace could overheat and cause a fire. In this blog post, we’ll explain what a furnace limit switch is, how it works, and why it’s important to keep it in good working order.

A furnace limit switch is a type of safety switch that is mounted inside the furnace. This switch is triggered when the temperature inside the furnace reaches a certain point. The limit switch is designed to shut off the furnace before it gets too hot, preventing the risk of overheating and fire. The temperature at which the limit switch is triggered is usually between 130 and 160 degrees Fahrenheit.

When the furnace limit switch is triggered, the furnace will shut off until the temperature inside the furnace drops below the limit switch’s set point. The furnace will then restart and continue to operate normally. However, if the furnace limit switch is not working properly, it may not shut off the furnace when the temperature reaches a dangerous level. This can be a major safety hazard and should be addressed immediately.

How Do You Keep Your Furnace Limit Switch in Good Condition?

It’s important to keep your furnace limit switch in good working order. Regularly inspect the switch for signs of wear or damage. To keep your furnace limit switch in good condition, it’s also important to keep it clean. This can be done by using compressed air to blow out any dust or debris that may have accumulated inside the switch. It’s also important to check the wiring of your furnace limit switch periodically. If any of the wires have become loose or frayed, they should be replaced.

Aside from what we’ve already mentioned, it’s also vital to make sure that the furnace limit switch is the correct size for the furnace. If the switch is too small, it won’t be able to sense the temperature accurately, leading to the furnace shutting down prematurely. If the switch is too large, it could lead to the furnace shutting down too late, allowing the furnace to become dangerously hot.


Overall, the furnace limit switch is an important safety component in any HVAC system. It is designed to shut off the furnace before it gets too hot, preventing the risk of overheating and fire. Make sure to regularly inspect the switch for signs of wear or damage and contact a professional HVAC technician if needed. By keeping your furnace limit switch in good working order, you can ensure the safety of your home or office.
