How to Prevent Carbon Monoxide Leaks in Your Furnace

As the heating season is in full swing, it’s essential that you are aware of and avoid any possible hazards that may come from the furnace. Many furnaces are a gas-burning appliance, which means they produce carbon monoxide. A carbon monoxide leak can be extremely dangerous and possibly life threatening. Fortunately, there are steps you can take to prevent a carbon monoxide leak from happening.

Where Does Carbon Monoxide Come From ?

In order to understand how to prevent carbon monoxide leaks in your furnace, it is necessary to understand where carbon monoxide comes from within your furnace. Carbon monoxide is a byproduct of the combustion process that occurs in a gas-powered furnace; it is mostly contained within the walls of the heat exchanger. When your furnace is operating correctly, the gas flows through the flue pipe and is safely vented out of your home. One of the main reasons for carbon monoxide leaks is when the furnace develops a crack in the heat exchanger or the flue pipes, which causes the carbon monoxide to be released into your home, instead of being carried outside.

How to Prevent Carbon Monoxide Leaks in Your Furnace

How to Prevent Carbon Monoxide Leaks

One of the easiest and most effective ways to prevent carbon monoxide leaks to have regular maintenance and inspections of the furnace. It is highly recommended that you have the furnace professionally inspected and routine maintenance is done in the fall before you turn the furnace on for the first time. During a maintenance inspection, the technician will perform a number of tests to ensure there aren’t any potential problems with the furnace, including using specialized equipment to examine the heat exchanger for signs of cracks or damage. Other things you can do to prevent carbon monoxide leaks include:

Change the air filter regularly: One cause of carbon monoxide leaks is the backup of airflow into the heating system. Clean filters will help to prevent the risk of backup.

Make sure the furnace was properly installed: If you are unsure about the age of your furnace or you have recently had a new furnace installed, it is important to make sure it was installed correctly. For example, if the blower or duct work has been installed incorrectly, it may develop issues with venting the carbon monoxide. Always make sure that any extensive work done on the furnace was done by a professional.

Install carbon monoxide detectors: A carbon monoxide detector may not directly help prevent carbon monoxide from escaping from the furnace, but it will alert you of high levels of carbon monoxide before it is too late.

If you suspect a leak in your furnace, contact the experts at AJR Heating, Air Conditioning, and Refrigeration right away for all your furnace repair needs.

The Importance of Furnace Maintenance

Your furnace controls the temperature and moves air throughout your home. Besides regulating comfort levels, your furnace system also filters out dust and allergens. An annual preventative maintenance inspection, by a qualified service technician, keeps your system functioning at peak efficiency. An inspection identifies issues before they go too far, and become unsafe or more costly to repair.


Safety checks ensure your equipment is running as safely and efficiently as possible. Regular furnace maintenance helps keep you safe by checking for carbon monoxide (CO) emissions. An inspection also checks the unit’s safe operating temperature.

Energy Bills

An energy efficient furnace can cause high energy bills when not properly maintained. In warm seasons, your furnace isn’t running, but still accumulates dust and dirt that can damage internal mechanisms. An annual furnace tune-up, before the heating season, identifies and helps prevent future problems resulting in higher energy bills.

The Importance of Furnace Maintenance

Moving Parts

Your furnace has many moving parts including fans, belts, and motors which require regular maintenance to remain in top working condition. Lubrication, tightening, cleaning, and replacing worn parts are all needed, on a regular basis, to keep your furnace running properly and efficiently.

Wear and Tear

Your furnace has safety features built in to regulate the way it turns on and off. If these sensors and other parts don’t function correctly, it could result in the unit shutting down and then powering back up frequently. Over time, this burden on your furnace system could shorten its lifespan or make parts wear out sooner. Frequent cycling also causes higher energy bills.


Your manufacturer’s warranty may require regular furnace maintenance. The lack of maintenance may void the warranty. This leaves you with bearing the costs of heating system repairs or replacement that could’ve been avoided with regular maintenance.

Don’t let a lack of furnace maintenance leave you and your family in the cold. The longer a problem goes unattended, the more damage can occur. Avoid unexpected breakdowns, that come along with unforeseen expenses, by having regular furnace maintenance

How to Prepare Your Furnace for the Winter

Winter is upon us, and if you haven’t gotten your furnace ready for the season, now’s the time. It doesn’t take much time or effort to ensure your furnace is ready for its debut, and we’re here to help you get it done. Keep reading to learn 6 things you need to do to get your furnace ready for winter.

Get your Furnace Winter-Ready

It’s that time of year again when you call upon your furnace to keep you warm. Of course, it can’t do that without a little help from you. take the following steps before turning it on to ensure it works its best.

1) Replace the air filter: Ideally, you should be replacing the air filter on your unit every month. If you haven’t, now’s a good time to do so.

2) Upgrade the air filter for best performance: If you’re using a flat filter, consider upgrading to a better filter for better performance from the unit, and better health for the occupants of your home. Better filters remove allergens to keep inside air cleaner, which is important during the cold winter months when the house is sealed up tight.

How to Prepare Your Furnace for the Winter

3) Vacuum out air vents and ducts: Dust can build up inside air vents and duct work. Take off vent covers and use your vacuum’s hose attachments to suck up dust buildup as far down the duct as possible.

4) Check the belts: Turn off the main power to the furnace and open its access panel to check the blower belt for cracks. If you notice wear, replace it.

5) Consider a set-back thermostat: If you don’t already have one, consider replacing your old thermostat with a new setback thermostat to save money. These thermostats automatically lower the temperature if you are gone or asleep. You could save as much as 75 percent on the cost of operating your furnace.

6) Inspect the unit’s outside operations: Go outside and make sure the area around the unit is clear. Also, make sure the exhaust flue is working properly. Remove any overgrown brush or debris that might interfere with the unit’s operation.

If you have questions about how to get your furnace ready for winter, or you discover the unit needs more than the simple maintenance described in these steps, be sure to contact a reputable heating technician in your area.

How Can a Broken Furnace Contaminate the Air in Your Home?

The job of your furnace is to provide your home with heated and cooled air as well as air that has been filtered and cleaned of outside contaminants. There are a few different ways that a broken furnace can affect the overall health of the air in your home and that can end up making your home less healthy than it can be.

The first risk factor is of course that your furnace may not be filtering the air properly if it is broken. In a normal furnace air is forced through a filter before it enters your home. If the furnace is working properly, it will help to remove the contaminants that are present and will deliver clean air into your home. If the furnace is not working properly there is a chance that the air will bypass the filter and not be clean when it enters your home.

Another risk factor is that a broken furnace may deposit silt and other particulates into your home from the interior of the furnace. Depending on where the issue is with your furnace, there may be particles that are part of the furnace that make it into the air when the furnace is on. These particles may be small and look like dust and they may be larger and pose an even bigger threat.

How Can a Broken Furnace Contaminate the Air in Your Home

You may also be experiencing air that is being forced through a broken system and therefore has silt and other deposits in it making it less than healthy to breathe. No matter how your broken filter is contaminating your home, you should work to have it repaired quickly so that you and your family can get back to having the clean air that a properly functioning system provides on a daily basis. These issues can be avoided, with regular maintenance of your furnace you can have a working system all the time.

How Can You Determine the Best Furnace Size for Your Home?

There are a wide variety of residential gas furnaces available in different sizes. With a few basic calculations, you can get a rough estimate of the size of furnace your home needs, but it is strongly recommended that you consult with an experienced heating and cooling specialist before making a purchase.

How much square footage does your home have?Measurements for rooms that you do not plan on heating and cooling, like sunrooms, patios, workshops, and garages, should be excluded from your calculations. Measure how high your ceilings are. Most sizing charts will assume that your home has 8 foot ceilings. If the ceiling height in your home is different, you need to make a note of that.

Think about the type of climate you live in, each season’s length, and the high and low temperatures. For example, Dallas, Texas is known for its hot, arid weather; although, other parts of the state experience all four seasons. As a general rule, the colder the winters are, the bigger size of furnace you will need.

How Can You Determine the Best Furnace Size for Your Home

Consult with a furnace installer or manufacturer to determine the appropriate size of furnace for your home. However, be aware that installers and manufacturers don’t always use the same sizing and recommendation charts.

Talk to a heating and cooling expert for load calculations and recommendations before choosing a furnace size. Although recommendation charts offer a great starting point, there are a number of other factors you must take into consideration, like the construction and age of your home, how much insulation your home has, and the quality of your doors and windows.

Signs That Your Furnace Is Beyond The Point of Repair

If you take care of your furnace and follow the manufacturer’s furnace maintenance recommendations, then your furnace can last for quite a long time. However, if you are in need of furnace repair yet again, it may be time to consider replacing it altogether. Here are a few signs that your furnace may be beyond the point of repair.

Frequent loud operation. Strange noises are a strong indicator that it’s time to contact a heating and cooling professional. If these noises are becoming the general rule, instead of the exception, your system may need replacing.

Signs That Your Furnace Is Beyond The Point of Repair

Expensive heating bills. If you’ve had your furnace for quite some time, then you have a general idea of what to expect each month in terms of heating costs. If your bills suddenly increase unexpectedly, this is a sign that you’re in need of furnace repair; however, if your heating bills have slowly become higher and consistently stayed there, this is a sign that your furnace is nearing the end of its lifespan.

Rust. With a furnace, it generally takes years for rust to appear; however, once rust does begin to appear on its interior components, it’s a signal that your furnace has outlived its usefulness. Rust will eventually cause cracks to appear in your furnace, which can result in carbon monoxide leaks, so you should have it replaced as soon as possible.

With any of the aforementioned signs, you should always bear in mind your furnace’s age. If your furnace is 20 years old or older, you’re due for a replacement, even if it is still operating fairly well. At the first sign of trouble, it’s time to call a heating and cooling professional to replace it.

5 Sure Signs That Your Furnace Needs Repair

Unfortunately, most homeowners don’t think of furnace maintenance or other HVAC services until the peak season arrives. Like most other HVAC equipment, furnaces have a lifespan and occasionally require furnace repair, but they often give us clues regarding impending breakdowns. Here are 5 warning signs that you may be in need of furnace repair:

1. Your unit is 15 years old or older. The average lifespan for a furnace is between 15 and 20 years. Instead of waiting for your furnace to croak, be proactive and have it replaced in the off season in order to avoid expensive emergency repairs.

What to Expect the First Time You Turn on Your Furnace This Season

As crisp air of fall gives way to the cold bite of winter, it’s important to make sure that your heating system will be up for the task of keeping your home nice and cozy all winter long. The last thing you want to do is to wait until the last second to test whether your furnace will work, or you could end up with a busted heating system in freezing weather with no way to get it fixed for days. It’s important to check out and test your heating system early, to make sure that it will be running reliably when the dead of winter arrives.

Do Some Basic Maintenance

Furnace maintenance is essential, so at the very least, you need to change the filter, to ensure that dust and debris don’t gum up your furnace’s inner workings. Once that’s done, turn the furnace up to a comfortable level and make sure that it’ll heat up the whole house. If you notice that your furnace is blowing cold air even after many minutes of running, call a heating and cooling specialist immediately to get it looked at.

What to Expect the First Time You Turn on Your Furnace This Season

Watch for Warning Signs

When the furnace is running, take a listen for any unfamiliar noises, any hiccups in the blower, or any odd smells coming through the registers. Warning signs are often subtle, but they can give you the crucial warning you need to fix a problem before it becomes an expensive ordeal.

Do it Early

The biggest mistake most people make is waiting until the last second to test out their furnace for the winter. It’s understandable that you would not want to waste money running a heater that you don’t need, but it’s crucial that you diagnose any problems early, since the HVAC companies could be swamped with calls later in the season.

3 Signs of a Failing Furnace

Sometimes appliances fail with little or no warning. Other times, homeowners are fortunate enough to experience some warning signs, and when the signs of failure motivate the homeowner to call a professional, complete failure can often be avoided, or at least put off. When it comes to your home’s furnace, there are 3 common signs that suggest your furnace is failing.

1. Strange Sounds – We all know that furnaces make sounds from time to time. It is usually not of concern when the furnace makes a sound here and there, but when you begin to hear sounds that you have never heard before, your furnace might be on its way out. Grinding, clicking, and squealing sounds are not normal and suggest you should make a call to a furnace repair professional.

2. Unusual Odor – Most of us know what our furnace smells like when it is turned on for the first time of the season. That smell typically dissipates rather quickly and is considered somewhat normal. If your furnace is producing a smell that is unpleasant and does not go away, then it is time to contact a professional. Remember, furnaces can produce carbon monoxide gas, which is deadly and odorless. For this reason, it is wise to have a carbon monoxide detector in the home. The furnace might also have a flaw causing a natural gas leak. If you notice a sulfur smell in your home, contact your natural gas provider immediately and vacate the premises.

3 Signs of a Failing Furnace

3. Unstable Temperature – While this might be a function of a broken thermostat, it could also indicate a major problem with your furnace. To troubleshoot, try a new thermostat and see if the problem is fixed. If the temperature remains inconsistent, you should contact a professional.

Furnaces, like other major appliances, have a lifespan. In general, if you maintain your furnace properly, you can expect it to function well for a significant amount of time. However, if you experience one or more of these problems, it is probably wise to begin putting some money aside to purchase a new furnace. No matter what type of attention your furnace needs, trust the experts at AJR Heating, Cooling, and Refrigeration, Inc. for all of your maintenance and repair needs.

When Should You Schedule Your Annual Furnace Tune-Up?

Many homeowners don’t give their furnace much thought until the outside temperatures start to drop and they need to heat their homes. Unfortunately, at this point, some homeowners find that their furnace isn’t working as it should, and they wind up scrambling to find someone to perform necessary furnace repair. In order to ensure that your furnace will work when you need it to during the colder months of the year, you should schedule a yearly furnace tune-up in the late summer or early fall. Scheduling a tune-up before the weather gets cold will give you enough time to make any necessary repairs before you need to rely on your furnace.

During a tune-up, the technician should check the airflow. If your furnace has restricted or limited airflow, then it causes a strain on your furnace that will diminish its lifespan. Since furnaces burn fuel, the combustion process also needs to run efficiently because any issue can lead to gas leaks and high carbon monoxide levels, which, of course, can lead to serious health risks for you and your family. Your technician will ensure the combustion process is running smoothly and will check the different parts in the gas system.

When Should You Schedule Your Annual Furnace Tune-Up

When your furnace begins to run inefficiently, you can use up to 40% more energy, which then translates to higher bills and costs. Receiving a tune-up will keep your furnace functioning effectively. Your technician should clean out the burner and blowers and also check the thermostat. The thermostat needs to be calibrated so that your home is at a constant temperature and your energy usage is manageable. Your HVAC technician will also need to lubricate any moving parts in order to reduce the energy consumption and unclog the condensation drain to prevent water leakage or indoor humidity.

Furnaces are meant to last 15 to 20 years with proper maintenance, and it is much more costly to replace a furnace than it is to schedule regular maintenance. The professionals at AJR Heating, Cooling and Refrigeration Inc. can tune-up your furnace now before you experience any major complications when the cold weather sets in.
