Why Is My Furnace Tripping the Breaker? (And Other Common Heating Issue Questions Answered)

Tuesday, February 1st, 2022

If you’re like most people, you probably switch your thermostat to heat when your house gets below 64 degrees Fahrenheit. You probably set your heat to about 65 to 70 degrees. This is just enough to keep you and your family comfortable during the winter months.

 

But, what happens if something goes wrong with your furnace? Why would a furnace tripping the breaker be a problem?

 

The bad news is that furnaces can develop many different issues. The good news is that most of them are easily resolved. 

 

Read on to learn what kind of furnace repair you might need right now.

 

 

Furnace Tripping the Breaker

 

 

There are two major reasons why the furnace might trip a breaker. Both indicate that there’s a problem with the electrical circuits in your home.

 

The first possible issue is the breaker itself. This could be because the breaker is old or faulty. It could also be that the breaker isn’t powerful enough to support the furnace.

 

The other possible issue is the furnace. It might be that the furnace needs more electricity than the breaker can handle. You might need either a smaller furnace or a stronger breaker.

 

 

Heating System Won’t Switch On

 

 

There are many reasons why a heating system wouldn’t turn on at all. The first, of course, is that the breaker tripped the last time the furnace turned on. This prevents electricity from getting to the furnace in the first place.

 

It could also be an issue of a short in a wire somewhere. This prevents enough electricity from getting to the furnace to turn it on.

 

Other issues might include faulty parts or an open service door to the furnace.

 

 

Low Airflow

 

 

Many internal issues cause a low airflow from your heating system. For this reason, it’s very common among heater issues. Causes range from simple issues like a closed vent to more complicated issues like a failing fan motor.

 

A closed vent is something you can check and fix yourself, so it’s, fortunately, the cheapest issue to fix. 

 

Clogs in the vents also prevent air from flowing as well. This issue, however, usually requires professional help to resolve.

 

Your furnace repair professionals might also check the fan motor to make sure it’s not failing. If it isn’t spinning as fast as it should, you may need a new motor.

 

 

Your Furnace Blows Cool Air

 

 

Also among the common heating issues is when your HVAC blows cold air instead of hot. The good news is that this indicates that the airflow and fan motor are both fine. The bad news is that this means your furnace isn’t producing heat.

 

This is usually the result of faulty parts. A good example of this is the pilot light failing. The pilot light is responsible for creating the small flames that generate the heat in the furnace.

 

If this piece doesn’t work, then you get a furnace that only blows cool air instead of hot.

 

 

Burning Smell

 

 

This one may or may not be a major issue with your heating system. If you only notice this the first one or two times you turn your furnace on for the winter, then it’s probably alright. The furnace just has some dust in it from the winter.

 

However, if the smell seems very strong or persists after that, then you may need to have a look at your furnace. This could mean faulty parts or bad wiring. If these issues continue, they could result in an electrical fire.

 

It’s best to have these issues resolved quickly before that happens.

 

 

Short Cycling

 

 

Short cycling refers to when your furnace turns on only to turn back off quickly. This is bad for your furnace since it causes more wear on its parts.  There are also many reasons why this might happen.

 

For example, if your thermostat is right under a vent, this can trick it into thinking that your house is warming up faster than it is. This causes it to turn the furnace off faster than it should. 

 

It might also be because of faulty parts. Furnaces have built-in safety features to prevent gas leaks and electrical fires. These activate when a problem is detected with a part.

 

 

Detecting Carbon Monoxide

 

 

If you have a gas furnace, then you should have a carbon monoxide detector. Carbon monoxide is odorless and tasteless, so the human brain can’t detect it. However, it’s also deadly to those who have prolonged exposure to it. 

 

Carbon monoxide is produced by your furnace but is supposed to be funneled out by a chimney. This releases the deadly gas into the air and away from human lungs instead of through your home for you to breathe in.

 

If your detector is going off frequently, you might have a clog in that chimney.

 

 

Noisy Heating System

 

 

This issue is a matter of trusting your instincts. You know what your heating system sounds like when it runs. That being said, there are many reasons why a furnace would suddenly become noisy. 

 

For example, there may be a loose part inside of your furnace. When the fan blows, it shakes and rattles that loose part. This vibration travels through the vents and makes your heating system seem quite loud.

 

If this is the case, it’s best to get an expert out to fix the issue as soon as possible. These issues only get worse if they’re allowed to go on and soon you’ll be dealing with something more serious than a loose part.

A Simple Furnace Maintenance and Inspection Checklist For This Winter In Charleston

Tuesday, December 28th, 2021

Did you know that you can increase your furnace efficiency with regular maintenance? Several Americans rely on furnaces to heat their homes. These handy appliances contribute a lot to a home’s monthly energy consumption.

 

If your furnace is old, damaged, or not well-maintained, you are likely to deal with high energy bills. Regular furnace maintenance will ensure that the appliance works at an optimum level and remains safe and efficient.

 

Here is a checklist of the services you should expect from a furnace maintenance technician.

 

 

Flame Sensor and Burner Cleaning

 

 

The furnace flame sensor is a small metal rod located in one of the burners. The main purpose of the flame sensor is to ignite all the burners on the surface. If the sensor doesn’t detect a flame, it will shut off the furnace.

 

Additionally, if the burners are ignited but the flame sensor is dirty, it will also shut off the furnace. Therefore, to make sure that the flame sensor works well, the HVAC technician will inspect, remove, and scrub it to remove built-up char.

 

 

Checking Thermostat Settings

 

 

It is vital to check and test the thermostat to make sure it is operating well. The technician can use a portable temperature sensor to check if the thermostat is reading the right temperature.

 

If it is on a schedule, they will test to see if it turns on and off as it should. Depending on the type of furnace you have, the technician will also check the fans for speed and ensure that the dampers or valves are functioning well.

 

They will also program it according to how much time you spend indoors. Programming the thermostat will save you money and make sure your home is comfortable throughout.

 

Remember if you hear any unusual sounds from the thermostat (especially when the furnace starts) or smell a burnt odor, you should get in touch with your HVAC repair service company immediately.

 

 

Air Filter Maintenance

 

 

Your home furnace system also includes an air filter. The main purpose of the air filter is to prevent dust, dirt, and other contaminants from getting into your home. A good rule of thumb is to change the air filter after every three months.

 

Though you can replace the filter with a few DIY steps, it may be ideal to let the right professionals handle it. HVAC technicians know the best air filter for your furnace and will help you save more.

 

 

Furnace Humidifier Cleaning

 

 

If you are in a dry climate, your furnace will also include a humidifier. It adds moisture to the air and helps in maintaining the right humidity levels in your home. This is crucial for indoor comfort and good health.

 

Regardless of the type of humidifier in your furnace, the technician will clean it and make sure it is working properly. Additionally, they will also check to see if the damper is set in the right position and check for any other damages.

 

Regularly maintaining the humidifier will ensure longevity and efficiency.

 

 

Ductwork Inspection and Maintenance

 

 

The furnace ductwork’s main job is to serve warm air throughout your home. If there are air leaks, mold, or dust in the furnace, the ductwork will not operate as it should. 

 

Therefore, to maintain efficiency, the technician will inspect the ductwork for signs of physical damages, clogs, or rust and clean or repair it.

 

Remember to keep any condensation or water away from the ductwork. Moisture will encourage the growth of mold. This will cause air leaks and pose a health risk.

 

 

Heat Exchanger Inspection During Furnace Maintenance

 

 

This is the core heating system in the furnace. The heat exchanger allows hot gases to transfer heat to the air blowing to and from the air registers. The integrity of the heat exchanger determines how well the system expels the noxious gases.

 

These gases include carbon monoxide gas which can be harmful to humans. To ensure safety, it is vital that the technician inspects the heat exchangers and detects gas leaks. Several experts also recommend installing a CO2 monitor or detector in your home for additional protection.

 

Regular heat exchanger maintenance will help detect any damages in good time and save you from costly replacement.

 

 

Blower Maintenance

 

 

The furnace blower circulates air throughout the home. It ensures that the heat from the furnaces reaches every part of your home. Note that, if the furnace blows cold air, get in touch with your HVAC company immediately.

 

To maintain the blower, the technician will check the fan wheel to confirm if they are spinning smoothly. They will replace worn-out motors and check the blades, bets, and pulleys. The technician will oil the moving parts and replace or repair any worn-out parts.

 

 

Furnace Electricals, Controls, and Safety Inspection

 

 

All heating appliances include several electrical units, operating controls, and safety functions. They are designed to make sure the furnace works well and can shut down in case of a malfunction.

 

Regular maintenance helps to ensure that such systems are well-serviced and operate safely at maximum efficiency. Keeping your furnace healthy and reliable gives you peace of mind.

 

Therefore, the technician will check for rusty terminals, loose wires, and more.

 

 

Use Professional Furnace Repair and Maintenance Services

 

 

Routine furnace maintenance and inspection are vital to the efficiency and longevity of your furnace. To have a reliable and well-functioning furnace, it may be ideal to work with a professional HVAC repair and maintenance services provider in your area.

Why Is My Furnace Blowing Cold Air?

Tuesday, November 30th, 2021

Furnace problems are never welcome. A furnace that has stopped working or is blowing cold air is frustratingly inconvenient.

 

A lot of things can cause your furnace to behave strangely. This blog will look at some of the most common furnace problems, how you can troubleshoot them, and what you can do to fix them.

 

 

Check the Thermostat

 

 

Your thermostat determines the temperature in your home and configures your furnace to reach the desired room temperature. Sometimes your thermostat can be set incorrectly, which will cause your furnace to blow cold air.

 

 

Check to see if your thermostat is set to heat. If it’s set to cool, that may be the problem. You’ll also want to make sure that your thermostat is set to “Auto” and not “On.” The auto setting configures your fan to stop blowing when the desired temperature is reached. 

 

 

If it’s set to on, this will keep the fan running even when the furnace is off, which means it’ll be blowing cold air.

 

 

The Furnace Isn’t Warmed Up

 

 

If you notice your furnace blowing cold air, it could simply need more time to warm up. Some furnaces need upwards of 15 minutes to reach maximum potential. This could also be the case on colder days when the outside air temperature dips below 30 degrees Fahrenheit. 

 

 

Give your furnace time to warm up for at least 15 minutes. If your furnace is still blowing cold air after 15 minutes, call a professional to diagnose the problem.

 

 

The Filter Is Dirty

 

 

The air filter from your heating and cooling system will catch dust, dirt, and debris. If your air filter is clogged, it can limit airflow to your furnace, which can cause it to overheat and shut off.

 

Be sure to check your filter regularly for any dirt or damage. If your furnace is blowing cold air, check the furnace to see if debris are caught in it. If there are, replacing your air filter should get warm air blowing again.

 

 

Condensate Lines Are Clogged

 

 

Condensate lines move water condensation away from your furnace. If there’s water present near the igniter, it will cause an ignition failure, which could cause your furnace to blow cold air. 

 

 

Your condensate lines can clog due to mold or other debris. Make sure to drain the condensate lines. If this seems like too much for you to handle, call a professional HVAC technician and have them take a look at the problem.

 

 

Check Your Ducts for Damage

 

 

Make sure to check your ductwork. If there is damage to your ductwork, this could cause warm air to escape, which will leave some rooms with cold air. This could be due to the age of your system, which can rust over time, or it could be from small rodents or other animals chewing through the ducts.

 

 

Make sure to inspect the ducts for any holes or damage. You can seal damaged ducts with tape or replace the damaged sections.

 

 

Check the Gas Supply

 

 

If your furnace runs on gas and is blowing cold air, check the gas lines or supply. You may be running low on gas, which means the pilot light keeps going out. Or, you may have damage to the gas line that supplies your furnace. 

 

 

The good news is that if there’s a fault with the gas supply, your furnace will automatically shut off. Have a professional check the gas lines and the gas supply for any problems.

 

 

Furnace Is Overheating

 

 

Most modern furnaces have safety features to prevent severe damage or disasters from happening. If your furnace is not working correctly, it will shut down on its own. Here are the main reasons why a furnace can overheat and shut off.

 

 

Mechanical Failure

 

 

Furnaces have many moving parts in order for them to operate. If one of these moving parts fails, it can make your furnace run harder, which can ultimately cause it to overheat. If you believe your furnace is failing due to a mechanical issue, have a professional HVAC technician inspect your furnace for any problems.

 

 

Clogged Filter

 

 

A clogged filter is one of the more common furnace problems. When your air filter is clogged, your furnace will be working harder than expected. If it runs too hard, it can potentially overheat and shut down on its own. 

 

 

Preventative maintenance is critical for your furnace to run optimally. Depending on the manufacturer’s recommendations, be sure to inspect and replace your air filter every 3-6 months. Doing this can prevent thousands of dollars in repair.

 

 

Age

 

 

Even with the best preventative maintenance schedule, your furnace can still overheat due to age-related internal failures. Age will lead to corrosion or worn parts. Over time, your furnace will need parts replaced to keep it running correctly. 

 

 

If this happens, you’ll have to ask yourself what the most cost-effective route to take is when it comes to your furnace issues. Failing internal parts in your furnace can range from a couple hundred dollars to several thousand dollars. 

 

 

If that’s the case, you may want to replace the entire furnace rather than have it repaired.

 

What to Do if It’s Still Blowing Cold Air

 

 

There’s nothing worse than a furnace blowing cold air on a cold night. The best thing is to look over all the tips we’ve gone over and diagnose the problem accordingly. 

 

 

Addressing these issues first will most likely solve your problems. If you’ve addressed all of these common furnace issues and you’re still having problems, you’ll need to reach out to an HVAC company and they can help.
