During the colder months, a gas furnace is essential for keeping your home warm and comfortable. However, if your furnace is blowing cold air, it can be a frustrating and uncomfortable experience. There are several reasons behind this problem, and it’s essential to understand the causes so that you can take the necessary steps to fix the issue.

A gas furnace blowing cold air can indicate a malfunctioning heating system. Your furnace may produce cold air for various reasons, such as lack of maintenance, a faulty thermostat, a pilot light or ignition system issue, dirty burners, or even the wrong furnace size. There could also be an issue with the air ducts or a leak in your home’s insulation. Understanding the underlying issue that causes your gas furnace to blow cold air is crucial in ensuring optimal performance and extending lifespan.

In the next sections, we will delve into the various factors that might be causing your natural gas furnace to blow cold air, emphasizing how to mitigate these issues to avoid any problems in the future. So, let’s dive right in!

Lack of Maintenance

Lack of maintenance is one of the most common reasons a gas furnace blows cold air. Regular maintenance is essential for furnaces to maintain peak efficiency and provide optimal heating. Over time, dust, debris, and dirt can accumulate, causing a range of issues that can cause the furnace to blow cold air.

The air filter is one of the most critical components of your furnace. Its primary function is to ensure that dirt, debris, and dust particles do not enter your furnace and damage sensitive components. Over time, however, the filter can become clogged, reducing airflow and compromising the unit’s efficiency. If the filter becomes too dirty, it can cause the furnace to overheat and shut off, leading to cold air blowing from the vents.

When air filters become clogged, they restrict the amount of air that flows through the furnace. Reduced airflow can lead to overheating and inefficient operation, causing your furnace to operate poorly. A dirty filter might also cause the furnace to work longer to reach the desired temperature, increasing energy bills.

Faulty Thermostat

A faulty thermostat is another common cause of a gas furnace blowing cold air. The thermostat is the brain of your furnace, sending signals to the heating system to regulate indoor temperature. If your thermostat isn’t working correctly, it could cause your furnace to malfunction, leading to cold air blowing through your vents.

A faulty thermostat can signal your furnace to turn off before adequately heating your home, resulting in blowing cold air. Additionally, if the wiring in your thermostat is compromised or incorrectly calibrated, it might cause the furnace to work poorly, resulting in cold air.

One way to determine if a faulty thermostat is causing the issue is by checking its batteries or power source. Older models might require replacement batteries, or they might need replacing altogether. It’s essential to consult a licensed technician before purchasing a new thermostat to ensure it’s compatible with your furnace.

Pilot Light or Ignition System Issue

A malfunctioning pilot light or ignition system can be another reason why your natural gas furnace is blowing cold air. The ignition system controls the flow of gas to the burners. If the ignition system or pilot light fails, the gas isn’t igniting and won’t produce heat, leaving you with cold air blowing from your furnace.

The pilot light is a small flame that burns continuously to ignite the furnace burners. If it goes out, the furnace won’t be able to light the burners, resulting in cold air blowing from the vents. The ignition system is responsible for lighting the pilot light and controlling the gas flow to the burners. If the ignition system is faulty, the furnace won’t produce heat, and cold air will be blown through the vents.

A furnace safety switch can also cause the pilot light to go out. If the safety switch tripped, it might shut off power to the furnace to prevent potential disasters. It’s essential to consult a licensed technician to handle this switch, as interfering with it may compromise your safety.

Dirty Burners

Dirty burners inside your gas furnace can lead to the furnace blowing cold air. As the burners accumulate dirt and grime over time, it can make it difficult for the furnace to produce heat, ultimately leading to inefficiencies in your heating system.

Gas furnaces use burners to heat air and ducts to circulate the warm air throughout your home. Burners have small holes which release gas as they ignite. However, these holes can become clogged with dirt and debris over time, restricting gas flow through the burners. When the gas flow is reduced, the furnace cannot produce enough heat to warm your home, leaving you with cold air blowing out of your vents.

Dirty burners can also pose a risk. A clogged burner increases the risk of gas escaping, leading to gas leaks, fires or explosions.

Wrong Furnace Size

If your furnace is too small or too large for the space you’re trying to heat, it can lead to various issues, ranging from uncomfortable temperatures to high energy bills. Having a licensed technician assess and recommend the right size of furnace can ensure your home is heated properly and efficiently.

If you’re having difficulty keeping your home at a comfortable temperature or if you’ve noticed a spike in your energy bills, it could be because you have the wrong size of furnace. A too-small furnace won’t be able to keep up with demand during extreme temperatures and will struggle to heat larger spaces. It means that certain areas of the house may remain cold while other parts get overly heated – not ideal.

On the other hand, a furnace that’s too large for your home will overheat quickly and turn off before intended, costing more money in energy bills due to frequent start-ups and stop-off cycles.

Conclusion

In conclusion, several factors can contribute to a gas furnace blowing cold air. Dirty burners, wrong furnace size, and insufficient airflow can all impact your furnace’s performance, leading to inadequate heating or cold air blasting through your home. Regular maintenance is vital for ensuring optimal performance from your system and for identifying any underlying issues before they get worse.

If you experience any problems with your furnace involving cold air, it is crucial to contact a licensed technician who will perform a professional assessment and provide the necessary repairs or replacements.

Do you ever find yourself lying in bed, and the house is quiet and dark? Then suddenly, you hear a faint humming coming from the depths of your furnace. It might sound uneasy but don’t worry. It’s probably just your furnace. But why does it make that noise when it isn’t even running? Chances are, there could be a variety of underlying causes to this phenomenon. From loose wiring to aging parts within the heat exchanger, understanding why your furnace makes a humming noise when off can help prevent more severe problems from arising down the road.

So let’s take an in-depth look at why the mysterious heating system hums and whines so you can get back to counting sheep without any worries!

Loose Parts

Loose parts inside the system can often cause the hum that may be heard when your furnace is off. Loose parts such as motors, fan blades, or belts can vibrate and create a low humming sound that is hard to ignore. If you have ever heard a high-pitched noise from your furnace, it’s likely due to some loose part.

For example, if a fan blower motor mount becomes worn out or begins to separate from the frame, it can cause an irritating vibration that resonates throughout your house. The same type of issue can occur with belts too. If they become loose or stretch out over time, they will create extra tension on the other system components and cause them to vibrate, leading to a humming sound when the furnace is off.

Blower Motor Issues

Another common reason your furnace may be making a humming noise when it is off is due to issues with the blower motor. If the motor mounting brackets are worn or corroded, they can cause vibrations in the system, which lead to a humming sound. Additionally, if the bearings in the blower motor become worn down, they may not be able to keep up with the demands of your system and will create extra vibration.

It’s important to remember that any extra tension put on the blower motor, such as a clogged air filter, will also contribute towards increased vibrations and humming noises coming from your furnace when it’s off. It’s best practice to check your air filter every month and replace it if necessary.

In addition, having an HVAC technician inspect your blower motor once per year is recommended to ensure everything is running smoothly and not causing any additional problems.

Failing Ignitor

A third potential cause of humming noises from your furnace when it is off could be a faulty or failing ignitor. The ignitor is the component responsible for lighting the gas burner inside your furnace, and if it fails, it can create a humming sound. It can occur due to wear and tear over time or due to dirt or debris clogging up the part and preventing it from functioning properly.

To check the condition of your ignitor, you’ll need to shut off power to the system and disconnect any electrical connections for safety precautions. Once this has been done, you’ll need to remove the access panel on the side of your furnace so that you can inspect the ignitor for any dirt or buildup.

It’s also important to note that if you’re hearing a loud banging noise from your furnace instead of a hum when it is turned off, this can also indicate an issue with the ignitor.

Clogged Air Filter

A clogged air filter is one of the most common causes of a low hum or buzzing sound coming from your furnace when it is off. The air filter, located in the return duct of your system, plays an important role in preventing dust and debris from entering the blower motor and damaging its operation.

However, the air filter can become clogged with dirt and grime over time, leading to restricted airflow. This lack of proper airflow can cause extra stress on the blower motor, resulting in a low humming noise from the furnace when it is off.

The best way to prevent this issue is to check your air filter regularly, at least once monthly, and replace it if necessary. It’s also important to use the right size filter for your system. An ill-fitting air filter can create additional problems, such as increased energy bills or even damage to components within your furnace.

Thermostat Problems

Although it may not be the most common cause, thermostat problems can also contribute to a humming noise from your furnace when it is off. If the thermostat is not calibrated correctly or has an outdated battery, then this can lead to a low hum emitted as the furnace attempts to work. Additionally, if you have recently had any electrical work done around your home, this could also have caused an issue with your thermostat’s wiring and led to humming.

To check whether or not your thermostat is causing the humming sound, you’ll need to look at its settings first to see if there are any faults within the thermostat, such as an old battery or incorrect calibration. You must address this before pinpointing any other causes of your furnace’s noise. If possible, try replacing the thermostat altogether, as faulty circuitry in older models may only become more problematic over time.

Conclusion

It’s important to remember that regular maintenance of your furnace and its components are paramount for avoiding any potential issues. It includes checking the air filter, ignitor, and thermostat every month and replacing worn-out components to prevent future problems.

Additionally, if you experience any low humming noise from your furnace when it has been turned off, you may need to investigate further into the cause of this sound. Checking the air filter, electrical components such as ignitors, and even the thermostat can help you identify what is causing the noise and address it. It’s, therefore, essential to carry out routine checks to ensure that your furnace is running effectively and efficiently all year round.

Efficiency Rating

The efficiency rating of the furnace you select will also impact its overall cost. High-efficiency furnaces typically carry a higher price tag than their standard counterparts. Still, they are more energy efficient and can save you money in the long run by reducing your energy costs.

Efficiency is measured by AFUE (annual fuel utilization efficiency), which represents the percentage of usable energy contained in natural gas or other fuels versus what is wasted while producing heat. The minimum legal AFUE rating for gas furnaces is 80%. Still, modern high-efficiency models can reach upwards of 98%, giving them a much higher purchase cost than standard units with lower ratings.

Brand Name

The brand name can be a factor when it comes to furnace costs. Bigger industry names such as Trane, Carrier, or Lennox often come with higher price tags due to increased overhead costs associated with advertising and product development compared to smaller independent brands that may be able to offer you discounted rates on similar products without sacrificing quality or warranty coverage.

It’s always worth researching and shopping for competitive pricing before deciding on any big-ticket item like a furnace.

Average Cost Range

The cost of a high-efficiency gas furnace can vary greatly depending on several factors, including size, installation costs, efficiency rating, and even brand name. On average, installation for a high efficiency gas furnace can range from $2,000 to $6,000, with higher-end models and additional add-ons pushing that figure even higher. Let’s take a closer look at what goes into this cost.

Labour Costs

Labour is probably the largest component in the final purchase price of your new furnace and will depend on the scope of work required. Generally, you can expect labour costs to range anywhere from $400 to over 1,000 depending on the installation’s complexities, like running new ductwork or opening walls to access existing pipe runs, etc. It’s always important to ask your HVAC contractor exactly what their labour charges include before agreeing on any work so that you are both on the same page when it comes time for payment.

Materials Costs

Materials are the second largest portion of the cost for a gas furnace installation behind labour costs. These will include all parts necessary for the job, like sheet metal returns and supplies for vented systems, venting materials for gas piping, and other related components necessary for a successful and safe installation.

Material pricing varies widely depending on items purchased, so it’s best practice to get quotes from several vendors or purchase them directly if allowed by your HVAC professional to ensure you are getting value in this portion of the job.

Tips For Saving Money On Your Furnace Purchase

Buying a furnace can be an expensive proposition, but there are ways you can save money on your purchase. Here are some tips to remember when shopping for your new furnace.

Shop around

Shopping around with multiple vendors is one of the best ways to ensure you get the best possible deal. Get bids from a few different places and compare prices and any applicable discounts, warranties or other additional services offered by each vendor to ensure you’re getting the most bang for your buck. Don’t be afraid to ask questions and look for special promotions like free installation or discounted parts, which could help you save even more!

Look out for Promotions

Manufacturers and HVAC professionals often run promotional offers or sales on certain units during peak times of the year, so it pays to stay aware of these opportunities and take advantage wherever possible! These promotions may include discounts on parts, rebates, giveaways or even free installation, so always check if any such deals are available when making your purchase decision.

Consider Buying Used

Another great way to save money on purchasing a new furnace is to consider looking at used models sold by reputable dealers who offer proper documentation and warranty coverage. Buying used can provide substantial savings without sacrificing quality if handled correctly, so this option might be worth exploring before splurging on a brand-new unit.

Conclusion

Buying a new furnace can be a daunting and expensive task. Still, with proper research, comparison shopping, and taking advantage of any promotional offers, it is possible to save money on the purchase. Ensure you understand all associated costs and make an informed decision based on value rather than looking for the lowest cost option, as this could negatively impact performance or reliability in the long run.

Finally, always consult with an HVAC technician who is knowledgeable and experienced before making any final purchases so that you are armed with all of the necessary information to make an educated decision. With these tips in mind, you can confidently move forward in your purchase, knowing that you have made the best choice for your wallet and home comfort needs!

Do you ever find yourself lying in bed, and the house is quiet and dark? Then suddenly, you hear a faint humming coming from the depths of your furnace. It might sound uneasy but don’t worry. It’s probably just your furnace. But why does it make that noise when it isn’t even running? Chances are, there could be a variety of underlying causes to this phenomenon. From loose wiring to aging parts within the heat exchanger, understanding why your furnace makes a humming noise when off can help prevent more severe problems from arising down the road.

So let’s take an in-depth look at why the mysterious heating system hums and whines so you can get back to counting sheep without any worries!

Loose Parts

Loose parts inside the system can often cause the hum that may be heard when your furnace is off. Loose parts such as motors, fan blades, or belts can vibrate and create a low humming sound that is hard to ignore. If you have ever heard a high-pitched noise from your furnace, it’s likely due to some loose part.

For example, if a fan blower motor mount becomes worn out or begins to separate from the frame, it can cause an irritating vibration that resonates throughout your house. The same type of issue can occur with belts too. If they become loose or stretch out over time, they will create extra tension on the other system components and cause them to vibrate, leading to a humming sound when the furnace is off.

Blower Motor Issues

Another common reason your furnace may be making a humming noise when it is off is due to issues with the blower motor. If the motor mounting brackets are worn or corroded, they can cause vibrations in the system, which lead to a humming sound. Additionally, if the bearings in the blower motor become worn down, they may not be able to keep up with the demands of your system and will create extra vibration.

It’s important to remember that any extra tension put on the blower motor, such as a clogged air filter, will also contribute towards increased vibrations and humming noises coming from your furnace when it’s off. It’s best practice to check your air filter every month and replace it if necessary.

In addition, having an HVAC technician inspect your blower motor once per year is recommended to ensure everything is running smoothly and not causing any additional problems.

Failing Ignitor

A third potential cause of humming noises from your furnace when it is off could be a faulty or failing ignitor. The ignitor is the component responsible for lighting the gas burner inside your furnace, and if it fails, it can create a humming sound. It can occur due to wear and tear over time or due to dirt or debris clogging up the part and preventing it from functioning properly.

To check the condition of your ignitor, you’ll need to shut off power to the system and disconnect any electrical connections for safety precautions. Once this has been done, you’ll need to remove the access panel on the side of your furnace so that you can inspect the ignitor for any dirt or buildup.

It’s also important to note that if you’re hearing a loud banging noise from your furnace instead of a hum when it is turned off, this can also indicate an issue with the ignitor.

Clogged Air Filter

A clogged air filter is one of the most common causes of a low hum or buzzing sound coming from your furnace when it is off. The air filter, located in the return duct of your system, plays an important role in preventing dust and debris from entering the blower motor and damaging its operation.

However, the air filter can become clogged with dirt and grime over time, leading to restricted airflow. This lack of proper airflow can cause extra stress on the blower motor, resulting in a low humming noise from the furnace when it is off.

The best way to prevent this issue is to check your air filter regularly, at least once monthly, and replace it if necessary. It’s also important to use the right size filter for your system. An ill-fitting air filter can create additional problems, such as increased energy bills or even damage to components within your furnace.

Thermostat Problems

Although it may not be the most common cause, thermostat problems can also contribute to a humming noise from your furnace when it is off. If the thermostat is not calibrated correctly or has an outdated battery, then this can lead to a low hum emitted as the furnace attempts to work. Additionally, if you have recently had any electrical work done around your home, this could also have caused an issue with your thermostat’s wiring and led to humming.

To check whether or not your thermostat is causing the humming sound, you’ll need to look at its settings first to see if there are any faults within the thermostat, such as an old battery or incorrect calibration. You must address this before pinpointing any other causes of your furnace’s noise. If possible, try replacing the thermostat altogether, as faulty circuitry in older models may only become more problematic over time.

Conclusion

It’s important to remember that regular maintenance of your furnace and its components are paramount for avoiding any potential issues. It includes checking the air filter, ignitor, and thermostat every month and replacing worn-out components to prevent future problems.

Additionally, if you experience any low humming noise from your furnace when it has been turned off, you may need to investigate further into the cause of this sound. Checking the air filter, electrical components such as ignitors, and even the thermostat can help you identify what is causing the noise and address it. It’s, therefore, essential to carry out routine checks to ensure that your furnace is running effectively and efficiently all year round.

It’s no secret that a whole-house humidifier is the best way to keep your home’s humidity at the correct level. But did you know that there are different types of whole-house humidifiers and that not all are equal? In this article, we will compare and contrast the two most popular types of whole house humidifiers- a whole house humidifier vs a portable humidifier.

What Is A Whole-House Humidifier?

A whole-house humidifier is a type of humidifier installed directly into your home’s HVAC (heating, ventilation, and air conditioning) system. Whole-house humidifiers can be either central humidifiers or console humidifiers. Central humidifiers are permanently installed into your HVAC system and require professional installation, while console humidifiers are portable units that can be moved from room to room as needed.

Whole-house humidifiers add moisture to the air as it circulates through your home’s HVAC system. We usually place a whole-home dehumidifier in your basement and work with your forced-air HVAC system. This effective gadget removes the surplus moisture in your indoor air as it travels through the heating and cooling return ductwork.

The dehumidifier turns the moisture into liquid, draining it into a sink or floor drain. After that, the dryer air is pumped once again through your rooms.

This humidifier is the most efficient and effective way to keep your house at the correct humidity level.

What Is A Portable Humidifier?

A portable humidifier is a type of humidifier that can be moved from room to room as needed. Portable humidifiers are small and compact, making them easy to move around. They are often used in rooms that do not have a whole-house humidifier installed or in addition to a whole-house humidifier to provide extra moisture in a specific room.

Portable humidifiers work by adding moisture to the air in a specific room. You can use them to target dry problem areas in your home, such as a nursery or bedroom. Portable dehumidifiers use a fan to draw in air that is too humid. Comparable to an AC system, the air is forced over coils cooled by a refrigerant. Most of the moisture in the air is condensed when the cold coils cool it.

The humidity content is now a liquid stored in a drip pan or detachable container, which you must typically empty by hand.

Portable humidifiers come in various shapes and sizes. Many even have cool mist options for added comfort.

How to Choose The Best Humidifier?

Now that you know the difference between whole-house and portable humidifiers, it’s time to choose the best humidifier for your home. Consider the following factors when making your decision:

The size of your home: If you have a large house, a whole-house humidifier will be more effective at evenly distributing moisture throughout your home. A portable humidifier will be sufficient if you have a smaller home or live in an apartment.

The climate you live in: If you live in an area with high humidity, a whole-house dehumidifier is an excellent option to help remove excess moisture from the air. A whole-house humidifier will help add moisture to the air if you live in an area with low humidity.

Your budget: Whole-house humidifiers are typically more expensive than portable humidifiers. A portable humidifier is a good option if you are on a budget.

Your needs: A portable humidifier is the best option if you are looking for a humidifier to use in specific rooms or for specific needs, such as a nursery or bedroom. A whole-house humidifier is the best option if you are looking for a humidifier throughout your home.

Conclusion

Both whole-house and portable humidifiers have their pros and cons, but which one is the best choice for you depends on your needs. If you have a large home, live in an area with low humidity, or are looking for a humidifier throughout your home, a whole-house humidifier is the best option. A portable humidifier is a good option if you have a smaller house or live in an area with high humidity. Consider your needs and budget when making your decision to choose the best humidifier for your home.

Changing your furnace humidifier filter is an essential part of maintaining your unit. Not only does it keep the air clean, but it also helps to ensure that the humidifier is running at its peak performance. But how often to change the furnace humidifier filter?

A furnace humidifier helps to add moisture to the air, which can be beneficial for many reasons. It can help prevent static electricity, cracked paint and wallpaper, and make the air feel warmer in the winter. We have put together this guide to help determine how often you should be changing your filter.

What is A Furnace Humidifier Filter?

Your humidifier filter, also known as an evaporator pad, water panel, or water pad, effectively holds and disperses moisture straight to the air as it passes through the furnace. Your humidifier’s filter is more appropriately thought of as a water retention pad.

It stores water for the furnace air to travel through and provides water to the atmosphere in your house. Your humidity control sends water through the pad when it detects a reduction in the humidity percentage to sustain the precise humidity level you want.

The filter is an essential part of the humidifier, as it helps to remove any impurities from the water before it evaporates. It includes things like dust, bacteria, and minerals. Over time, the filter will become clogged with these impurities and need replacement to continue functioning correctly.

How Often Should You Change The Furnace Humidifier Filter?

Now that you know how important it is to have a clean filter, you are probably wondering how often you should be changing it. The answer depends on a few factors, including the type of filter used and the air quality in your home.

If you live in an area with hard water, the minerals in the water can cause the filter to become clogged more quickly. In this case, you may need to change the filter more frequently. Additionally, if you have pets or someone in your home who suffers from allergies, you may need to change the filter more often.

Generally speaking, you should expect to change your furnace humidifier filter every one to three months. However, if you find that you are changing it more frequently than this, it may be a good idea to upgrade to a higher-quality filter. When your house needs humidity the most in the winter, you might need to replace the humidifier filter more frequently.

Choosing the Right Filter for Your Furnace Humidifier

When it comes time to replace your filter, it is crucial to choose one that is the right size and type for your humidifier. If you have a whole-house humidifier, you will need to make sure that you select a filter that is designed for this type of unit.

Additionally, you will need to choose a filter with the right MERV rating. The MERV rating measures how effectively the filter removes impurities from the air. The higher the MERV rating, the more effective the filter will be.

A filter with a MERV rating of 5 or 6 will be sufficient for most homes. However, if you have pets or someone in your home who suffers from allergies, you may need to choose a filter with a higher MERV rating.

Conclusion

Installing a new filter is a relatively easy task that you can do yourself. However, if you are not comfortable doing it, you can always hire a professional to do it for you. When it comes to how often to change the furnace humidifier filter, you should do it every one to three months, or more frequently if necessary. Choosing the right filter is also important, as you want one that is the right size and type for your humidifier and has the right MERV rating.
