Most people are used to moving into a home and not worrying about anything more than turning up the thermostat when it comes to temperature control. However, a furnace will likely need to be replaced at some point.
This process may seem intimidating for many, but understanding the basics of furnace installation can help ease any apprehension, whether tackling the job yourself or relying on a professional.
Key Takeaways
- When choosing a furnace, you’ll need to decide which format makes sense for your home – gas, oil, or electric.
- Signs it may be time to replace your old furnace include its age, rising energy bills, strange noises coming from your ducts, or needing to make frequent repairs.
- The installation process of a furnace involves disconnecting existing connections, removing and installing the new furnace based on local safety codes, checking gas lines and electrical components, and testing the unit for potential malfunctions.
- A new furnace installation can be a complicated and lengthy process and is best suited for a professional HVAC technician.
The Basics of Home Furnaces
The efficiency of your home’s central heating system depends on furnaces. Furnaces generate and distribute heat, resulting in a comfortable and warm environment for your family. They use fuel such as gas, oil, or electricity to heat air, water, or steam, which are then circulated throughout your home through ducts or pipes.
Types of Furnaces
- Gas Furnaces: Gas furnaces are the most commonly used type of furnace in homes today. They use natural gas to produce heat and are well-known for their high efficiency.
- Oil Furnaces: Oil furnaces, although less commonly used than gas furnaces, are typically found in older homes or regions lacking easy access to natural gas.
- Electric Furnaces: Electric furnaces use electricity to produce heat. Although they may not be as efficient as gas furnaces, they are generally more affordable to install. Consequently, electric furnaces can be a viable alternative in regions with milder climates where the furnace is not frequently utilized.
Like any other appliance in your home, your furnace requires regular maintenance to operate efficiently. Neglecting this essential care can result in decreased efficiency and higher energy bills.
Additionally, a furnace that is not adequately maintained can present significant safety hazards, such as the potential for carbon monoxide poisoning.
Signs Its Time for a Furnace Replacement
Knowing when it’s time to replace your furnace can be important, especially during the colder months when it’s essential to your home. Like any appliance, the furnace will eventually end its lifespan. Pay attention to some of the signs below that might indicate it’s time to replace your furnace.
Age of the Furnace
The average lifespan of a furnace is typically 15-20 years. If your furnace falls within this age range or is older, you should think about replacing it. Even if it is still functioning, it may not be as efficient as newer models, resulting in increased energy expenses.
Rising Energy Bills
If you have recently seen a rise in your energy bills but haven’t been using more energy, your furnace may be the cause.
As furnaces get older, they often become less efficient, meaning they need to run for longer periods to maintain the desired heat. This extended running time can lead to higher energy bills.
Frequent Repairs
Another sign that your furnace may need replacing is if it requires frequent repairs. If you’re constantly calling in professionals to fix various issues, replacing the furnace entirely might be more cost-effective. The cost of one-off repairs might not seem like much, but they can add up over time.
Inconsistent Heating
Have you ever wondered why certain rooms in your home feel warmer than others? It may indicate that your furnace is not efficiently spreading heat throughout the house.
Although problems with your ductwork could cause this, it is also plausible that your furnace can no longer effectively warm your entire home.
Strange Noises
As furnaces age, their noise levels tend to rise. Unusual sounds like banging, popping, rattling, or squealing coming from your furnace may indicate that it’s nearing the end of its lifespan. In such cases, it is recommended to seek the assistance of a professional to evaluate the situation and determine if replacing your furnace is necessary.
How to Prepare for a New Furnace Installation
To ensure a smooth installation of your new furnace, it’s important to prepare your home appropriately. Given that getting a new furnace is a significant investment, here are some steps to ensure it goes smoothly.
Evaluate Your Home’s Needs
Before selecting a new furnace, you should clearly understand your home’s heating needs. Consider factors like the size of your home, the number of rooms, and your local climate. These factors will help determine the type and size of furnace you need.
Choose the Right Furnace
You can shop for a new furnace once you understand your home’s needs. Remember, the most expensive or largest furnace isn’t necessarily the best choice for your home. Consult a professional who can guide you in selecting the most efficient furnace that meets your needs.
Clear the Area
To make the installation process as smooth as possible, clear the area around where your furnace will be installed. Remove any items that could be in the way of the installers. This helps protect your belongings and provides installers the space they need to work safely and efficiently.
Schedule a Pre-Installation Inspection
Before the installation day, schedule a pre-installation inspection with your HVAC company. During this inspection, they’ll check your existing system and ductwork to identify potential issues affecting the installation process.
How a Furnace Installation Process Looks
Understanding the process can alleviate any concerns or confusion when installing a new furnace in your home. Here is a step-by-step guide on how a typical furnace installation process works.
Step 1: Disconnecting Existing Connections
Before the installation begins, it’s crucial to disconnect all existing connections to your old furnace safely. This includes shutting off gas lines and electrical connections and removing ductwork.
This step ensures a safe working environment and prevents potential hazards. Professionals are trained to handle this step carefully, ensuring no residual gases are left, and all electrical connections are safely disconnected.
Step 2: Installing According to Code
The next stage involves installing the new furnace according to local building codes and manufacturer instructions. Every city has specific regulations regarding furnace installations to ensure safety and efficiency.
Moreover, not adhering to these codes could lead to problems down the line, such as voiding your warranty or failing a home inspection. Therefore, a professional installer will always ensure the installation meets all requirements.
Step 3: Checking Gas Lines and Electrical Connections
Once the new furnace is in place, the installer will check the gas lines and electrical connections. This step ensures all connections are secure and correctly installed, reducing the risk of gas leaks or electrical shorts.
It’s also crucial to confirm that the furnace receives the correct voltage and that the gas pressure is accurate.
Step 4: Testing the System
The final step in the furnace installation process is testing the system. This involves turning on the furnace and checking its operation.
The installer will verify that the furnace ignites properly, heats up, and distributes warm air throughout the home. They’ll also check the thermostat settings and ensure the system responds appropriately.
Tips to Maintaining Your Furnace Over Time
Taking good care of your furnace is crucial to its longevity and performance. Regular maintenance helps it run smoothly and reduces the risk of sudden malfunctions, particularly during the chilly months when you rely on it the most. To ensure your furnace remains in prime condition over time, here are a few tips you can implement:
Regularly Change the Air Filters
Regularly changing your furnace’s air filters is a simple yet effective way of keeping it in good condition. When a filter gets clogged, your furnace has to work harder than necessary, which can lead to higher energy consumption and possible damage.
Depending on your household’s needs, like if you have pets or allergies, it’s recommended to replace your air filters every one to three months.
Annual Professional Inspections
While there are many tasks you can do yourself, hiring a professional for an annual inspection is a wise investment.
A trained technician can spot potential problems that you might miss. They’ll check the furnace’s components, including the heat exchanger, blower motor, and burner flames, ensuring everything is in good working order.
Keep the Area Around Your Furnace Clean
Keeping the area around your furnace clean is another easy yet essential step. Make sure the site is free from dust, debris, and clutter. This prevents potential fire hazards and ensures proper airflow, which is crucial for your furnace’s efficiency.
Check Your Carbon Monoxide Detectors
Furnaces, especially those poorly maintained, can produce carbon monoxide – a dangerous, odorless gas. It’s vital to have working carbon monoxide detectors in your home. Test them regularly and replace the batteries as needed.
Lubricate the Furnace Blower Motor
Some furnace models require regular lubrication of the blower motor. If your furnace is one of these models, ensure you lubricate the motor as per the manufacturer’s guidelines. This can help avoid unnecessary friction and prolong the life of the motor.
Check the Thermostat
Remember to regularly inspect your thermostat. In some cases, heating issues could stem from a malfunctioning thermostat rather than a problem with the furnace. Verify that it is set to the appropriate temperature and test its functionality by switching between heating and cooling modes.
Make Sure Your Furnace Is Installed the Right Way
When it comes to installing a furnace in your home, it is crucial to approach the task with great care and not underestimate its importance. Although you might be tempted to tackle the job independently, opting for a professional installer is often the most prudent decision.
By selecting a qualified professional, you can have peace of mind knowing that your furnace will be installed correctly and by local regulations.
