22 Signs That Your Furnace is About to Break Down

If you live in San Antonio, you may not be fully aware of the status of your furnace because of the city’s mild winters. To ensure your furnace lasts another winter after the Texas freeze of 2021, look for warning indications of a breakdown and schedule repair work ahead of time.

Your furnace’s age is the most prominent symptom that it is on the verge of breaking down. If your furnace is more than a decade old, it’s time to start thinking about a new installation. Even if you don’t see these clear indicators, your furnace may be failing.

Your furnace is showing many signs of failure. Some of them are listed here.

Is your furnace starting and stopping?

If your furnace starts and stops several times during one day or week, there could be an electrical problem with your home’s wiring. It also could indicate that your furnace needs service.

What is the burner flame color?

The color of the burner flame indicates whether your furnace is working correctly. A yellowish-orange flame means that your furnace is running too hot. This can cause damage to your heating system and shorten its lifespan.

A red flame means that your furnace isn’t operating at all. You should contact a professional technician as soon as possible.

Is your Flue rusted?

Rusty flues are a sign that your furnace has been exposed to moisture. Moisture can enter your home through cracks in the foundation, windows, doors, and other areas around your house. These leaks can lead to rusting of the ductwork, which will eventually cause your furnace to fail.

Are your vents clogged?

Vents are small openings in your home’s roof that allow warm air from your furnace to escape into the outside atmosphere. If they become blocked by debris such as dust, leaves, or even insects, your furnace won’t have enough oxygen to burn fuel efficiently. This can cause your furnace to run inefficiently, leading to higher energy bills.

Are you noticing or smelling moisture buildup?

Moisture buildup inside your home can lead to mold growth. Mold can cause health problems like asthma attacks and respiratory infections.

Are your utility bills spiking?

If your utility bills are increasing, this could signify that your furnace is malfunctioning. The reason why your bill increases is because your furnace is consuming more electricity than usual.

Are there any water leaks?

Water leaking into your basement is a significant cause of HVAC failures. Water can seep under the floorboards and walls, causing rot and mold.

Do you hear strange noises coming from your furnace?

Strange sounds coming from your furnace could be a sign of a problem. They include rattling, grinding, or banging. These noises could indicate that your furnace is experiencing mechanical issues.

Are there signs of animal activity?

Animals chewing on wires, pipes, and other parts of your home’s HVAC system can lead to severe damage.

Have you noticed any unusual odors?

An odorless furnace is a good thing, but if you notice an unpleasant smell, this could be a warning sign that something is wrong with your furnace.

Have you seen any smoke?

Smoke coming out of your chimney signifies that your furnace might be having trouble. Smoke can be caused by several things, including overheating or a leak in your ductwork.

Has your furnace started making loud noises?

Loud noises coming from your furnace could indicate that it is about to break down. Loud noises may include grinding, creaking, groaning, or popping.

Have you noticed a decrease in heat output?

Decreased heat output is another sign that your furnace is breaking down. Heat loss occurs when cold air enters your home through cracks in your foundation, windows, or doors.

Is your furnace getting old?

Your furnace is considered “old” when it reaches 10 years of age. It becomes less efficient over time, so make sure to replace your furnace before it breaks down completely.

Are you constantly tweaking your thermostat?

If you are constantly adjusting the thermostat, then the furnace in your home may be about to break down, and you might not even notice it until the cold winter air starts coming into your house. If this happens, you need to call a professional heating repair service as soon as possible.

Have you made repeated service calls?

If you’ve been making multiple service calls to an HVAC technician each year, the chances are good that your furnace needs some serious maintenance or replacement. If you notice any of these symptoms, call your local heating company today!

Are there cold spots through your home?

If your home has become colder than usual during the last few months, it could indicate an issue with your furnace. The heat exchanger can fail when it gets too hot, causing air to bypass the unit. This causes the temperature of your home to drop.

The blower motor can also fail, which will cause your furnace to stop working altogether. It can happen at any time, but it’s usually due to a clogged filter or debris buildup.

Do you see more dust than usual?

Dusty air is standard in homes with furnaces, especially in the summertime. But if you notice that your home is getting dusty all year round, it could mean that your furnace isn’t running correctly. A dirty filter can restrict airflow and cause your system to run inefficiently.

Is Your Family Getting Sick More Often Than Normal because of a failing furnace?

When people get sick, they often blame their health problems on the weather. However, if you notice that your family members have been coming down with colds and flu more frequently than usual, it could be caused by a faulty furnace.

A malfunctioning fan or blower motor can cause air quality issues inside your home. As a result, you’ll find yourself coughing and sneezing more often.

A lack of proper ventilation can lead to mold growth, triggering allergies and other respiratory problems.

Does your furnace struggle to stay on?

If your furnace struggles to keep itself warm, it could indicate a problem. Heat exchangers can wear out over time, leading to reduced efficiency. In addition, the blower motor can burn out, which will cause your system to shut off automatically.

These are just a handful of possible signs that your furnace is on its way out. Contact us today to learn more about how we can help you maintain your furnace to keep functioning well into the future.

Do you see things that are not there?

Carbon monoxide poisoning is a silent killer. You might feel uneasy, hear noises, or even hallucinate. Headaches, nausea, and dizziness are also common. A failing furnace can emit carbon monoxide as a byproduct of combustion. Carbon monoxide levels should always be kept below 10 parts per million (ppm).

You can test for carbon monoxide using a carbon monoxide detector. These detectors come in both battery-operated and plug-in varieties. Plug-ins are best for detecting leaks, while batteries are better at finding high concentrations of CO.

You can also use a handheld gas meter to check for CO levels. Gas meters are available at most hardware stores. They’re inexpensive and easy to operate.

If you suspect that your home contains dangerous amounts of CO, contact our team immediately. We can help you identify and repair the source of the leak.

Do you smell gas?

Gas smells like rotten eggs when it comes out of a furnace. The odor is caused by carbon monoxide (CO) gas leaking from your furnace. Carbon monoxide is poisonous, so if you smell gas coming out of your furnace, call 911 immediately.

Furnace Repair and Replacement FAQs

How do I get my furnace replaced?

You can take steps to prevent the same situation from happening again. Contact us today!

The first thing you should do if you’re planning on installing a new heating system is to get an estimate from several different contractors. This way, you’ll know what kind of price range you can expect for the work and which contractor will give you the best deal.

The cost of replacing or repairing a furnace depends on how old it is and whether it has been appropriately maintained. A good rule of thumb is that a furnace replacement costs around $1,200-$2,000, and a repair runs between $500-$700.

A new furnace will typically run you anywhere from $3,000-$5,000, depending on the size of the home and the features installed. You can save money by shopping around and comparing estimates.

When you hire a professional HVAC technician to install a new furnace, you’ll have peace of mind knowing that they are qualified to handle all aspects of the job. They’ll also provide information on what type of furnace will fit your needs and budget.

You might want to consider hiring a contractor who specializes in furnaces. These professionals usually charge less than other technicians because they’ve already done this work hundreds of times.

When you replace your furnace, you’ll need to pay attention to the following things:

  • How long does it take?
  • What size is it?
  • Is there any special equipment required?
  • Does it come with a warranty?
  • Do you have enough room to store the new unit?
  • Can you turn off the power while the installer works?
  • Do you have access to gas or electric lines?
  • Will you need to move furniture or appliances out of the way?
  • Do you have a place to put the debris from the removal process?

If you plan to use a portable heater during the installation, make sure it’s large enough to heat your entire house. Also, check if the manufacturer recommends using a blower fan to circulate warm air throughout the room.

If you live in a cold climate, you’ll want to ensure that the ductwork is insulated so that the hot air stays inside where it belongs.

Before buying a new furnace, you should shop around for at least three quotes. The reason why you should compare prices is that some companies offer discounts if you purchase multiple units.

You should also ask each company about their warranties. Ask if they offer a 90-day warranty on parts and labor. If anything goes wrong within those ninety days, you won’t have to pay for repairs.

It’s important to note that most manufacturers don’t cover the cost of shipping the furnace. So, if you order one online, you’ll probably end up paying more than if you bought it locally.

You should also contact your local heating contractor to determine what repairs they recommend.

How often do you need to service your furnace?

The best way to know how often you should service your furnace is to check its manufacturer’s recommendations. You can also contact a professional for advice.

Furnace Repair Tips

Keeping it running smoothly is essential for your home’s central heating system. But sometimes, even the best-maintained systems need a little help. If you’re looking for ways to keep your home warm without spending too much money, here are some tips:

Check your thermostat settings. If you set your thermostat to turn off during certain times (like while you sleep), you won’t have to worry about waking up to a chilly house.

Make sure your vents are clear. Dust buildup can block airflow, which means your furnace isn’t working as hard to heat your home. To prevent this, regularly sweep or vacuum your attic and crawl spaces.

Keep your furnace well maintained. A dirty furnace filter can clog airflow and lower efficiency. Cleaning your furnace’s coil every two years helps ensure that it runs efficiently.

Keep your furnace cool. When temperatures outside get cold, you don’t want your furnace to run all night long. Turn your thermostat down to 60 degrees Fahrenheit whenever possible.

Don’t forget to insulate. Insulation keeps your home warmer in winter and cooler in summer. Adding insulation around your home can reduce energy bills by 30 percent or more.
