Not Sure What’s Wrong with Your Furnace? Read This First
We hardly notice our furnace when it’s working properly, but when something goes wrong, it can feel like the sky is falling, especially in the middle of winter. As cold weather drags on, your furnace has probably been busy these past few months. All that extra use can lead to a range of furnace problems, especially if you’ve been falling behind on maintenance. If there’s a problem with your furnace, find out what went wrong and how to fix it.
1. The Furnace Is Slow to Start and High Energy Bills
If you notice it takes longer than usual for your home to warm up and your energy bills are going through the roof, this might be a sign that you need to clean your furnace filters. When the filter gets clogged with dust and dirt, heat can’t pass through the opening as easily, which is why your home might be a little colder than usual. As you dial up the thermostat, your energy bills are going up, but you might not be feeling the warmth. Try cleaning off the filters yourself or request a tune-up from a local HVAC repair company.
2. Constant Temperature Cycling
If the temperature always seems to be in flux, it could mean that the air is having trouble getting around your home. Your vents and filters might be clogged. Or your thermostat may be malfunctioning. Feel your way around the vents in your home to see if the air is passing through. Clean your vents and filters to resolve the problem. If that doesn’t work, you may need to replace the thermostat.
3. The Furnace Isn’t Heating Your Home
This could refer to a range of common furnace problems. First, make sure your furnace is turned on and receiving power. If that’s not the issue, a faulty ignition or pilot light will prevent your furnace from generating heat. You could also be dealing with a mechanical problem or a clogged burner. In this case, it’s usually best to call for some backup and have your furnace inspected by a professional. Your furnace will need to be repaired or replaced.
4. The Furnace Is Constantly Blowing Air
If you feel the air coming through but it’s not getting warm, that’s usually a sign of a faulty limit switch. This is best handled by a professional furnace repair specialist.
5. Furnace Makes a Rough Scraping Sound
This sound will immediately get your attention. If you turn on the furnace and it sounds like two pieces of metal are scraping against each other, it likely means the ball bearings are worn out. Call a furnace repair specialist immediately.
All sorts of things can go wrong with your furnace when it’s blasting warm air into your home 24/7. You can avoid many of these problems with regular furnace maintenance. Have a professional inspect your HVAC system at least twice a year to prevent an unexpected breakdown.

How Cracked Heat Exchangers Can Lead to Carbon Monoxide Poisoning
Every year, many families put themselves at risk of carbon monoxide poisoning due to damaged and cracked heat exchangers in their furnace. Some Forced air type furnaces come with a stainless-steel condensing heat exchanger that releases warm air into the house. When working properly, the exchanger is supposed to separate the combustion process from the air that enters your home, but this component can break down over time, which can lead to the spread of carbon monoxide. This odor-less, color-less gas can lead to flu-like symptoms, a loss of consciousness, seizures and even death if you’re exposed for a long period of time. Learn more about the dangers of damaged heat exchangers and what you can do to protect yourself and your loved ones.
Why Heat Exchangers Fail
Heat exchangers aren’t designed to last a lifetime and will fail at a certain point. As this piece of metal heats up, blowers carry the warm air out of the furnace and into your home. Every time your furnace turns on and off, the metal will expand when it heats up and contract when it cools down. But this metal will deteriorate over time as it continues to expand and contract. Eventually, it will crack apart, which means there’s nothing separating the combustion process from the air you breathe, which can lead to carbon monoxide poisoning.
How to Recognize the Signs of a Failing Heat Exchanger
It’s nearly impossible to know if you have a damaged heat exchanger without visually inspecting the inside of your furnace. Unless you have some extensive HVAC experience under your belt, you’ll need to consult with a professional to have your home’s furnace inspected. If they find that your heat exchanger is damaged, they can easily repair this part of your furnace by either replacing the heat exchanger or the entire furnace. Heat exchangers are designed to last anywhere from 10 to 20 years, but these numbers can vary based on the type and how often you use your furnace.
If you fail to have your furnace heat exchanger inspected on a regular basis, you could expose your loved ones and yourself to carbon monoxide. You should install carbon monoxide detectors in your home, but this will not help you stop carbon monoxide from leaking into your home.
The Dangers of Exposure to Carbon Monoxide
Carbon monoxide is odorless and colorless, making it extremely difficult to detect. It may be several days before you realize this gas is leaking into your home. If you have a leak, short-term exposure to carbon monoxide can lead to flu-like symptoms, including headaches, dizziness, nausea, vomiting, and chest pain.
To make sure your home is free of carbon monoxide, you need to have your furnace inspected by a professional at least once a year. An HVAC repair specialist can help you keep an eye out for damage to your furnace’s heat exchanger. Stay safe and make sure your home is free of carbon monoxide by calling the pros at A-1 Guaranteed today!
