The Most Typical Furnace Problems:
Our experienced team has put together a comprehensive list of the most common problems you might face if you have a furnace. Read them all the way through to gain a little knowledge on your heating system!
Remember that your thermostat works on batteries which need to be replaced from time to time. If your house is chilly and you’ve headed to the thermostat to turn it on but found that it’s not working, don’t panic! Start with the most obvious of solutions first. Check the batteries!
If you have reasons to believe this might have happened, go to the breaker’s panel and find the circuit which controls your furnace. If it has been switched to ‘Off’ or if it’s in the middle, you can test it first. Switch it back and forth a few times to make sure it’s not broken. Once you’ve established it still works, turn it back to the ‘On’ position.
There’s a very easy way to tell if this is the issue with your furnace. If it still works but you know from previous experience or from past years that it’s not producing as much heat as it should, then its filters might be clogged.
Fortunately, changing your filters is a very easy job. Locate them, pull them out one by one and hold them out against a source of light. It the light cannot shine through them, then you need to change them.
Another sign that you must change your air filters is the way they smell. If, when you turn on your furnace, the air that comes out from the vents smells like dust or mold, change them quickly!
Another very common issue when it comes to furnaces is that the burner flames get contaminated with a lot debris. But checking them out is quite an easy task! Simply look at the flames. They should be bright blue and very even. This means that the burners themselves are clean.
However, if the flame is colored yellow, your burners may very well be dirty and in need of a good cleanup. They can be polished easily enough. But remember not to do this while the furnace is on. Turn everything off, including the gas itself!
You will also want to clean the area around your burner. Since you don’t use it that much, dust settles in there during the warm season. The best thing to do is to check all this in late autumn, before you need to use your furnace every day so you can avoid any surprises.
Sometimes, problems can be as simple as a switch not being turned on. But when your whole house is cold and you don’t have a working knowledge of your heating system, it can be devastating. So, if something is wrong, try the obvious solutions first. If you notice that the furnace switch is off after you have located it somewhere inside or next to the cabinet, switch it back on. Wait a few moments for the furnace to engage. This, consequently, leads us to the following.
If the furnace doesn’t engage, then you might have bigger issues than just flipping the switch on and off and you need to call in a specialist. We need to emphasize that actually repairing your heating system is a very serious matter that you should not undertake on your own. Please call us immediately, explaining exactly what happened. Our specialists will find the best and fastest solution when it comes to furnace repair in Baltimore, MD.
So, what might cause it to break down and make you call for furnace repair in Baltimore, MD?

Even though a gas furnace can either catch fire or explode, it's highly unlikely. Furnaces have multiple safety features designed to shut the furnace off if that problem should arise. Frequent maintenance is an easy way to put your mind at ease, so that you can always be confident that your furnace is in good working condition.
Rust is typically a sign of a more serious issue so it’s imperative to call an experienced HVAC pro. If the source of rust is your heat exchanger you will need to get it repaired or replaced immediately. This is a serious safety hazard because a rusted and cracked heat exchanger can leak carbon monoxide into your home, which is deadly.
A well maintained furnace can last 16-20 years. When your furnace reaches this age or older, you should start shopping for a new one. Without yearly maintenance the lifespan of your furnace can drop to 7-10 years. When it comes to servicing your furnace, we recommend you do it at least once a year. Our recommendation is to do it in the fall before the cold weather arrives.
No, it is critically important to consult a licensed HVAC expert for any type of furnace repair or installation. Working with natural gases, electrical work, and heavy equipment could result in serious injury or property damage. If damages or injuries occur due to unlicensed work, your homeowners insurance and any warranties you had are automatically void. Here are some ways safe ways to troubleshoot your furnace to determine if you need a full repair:
Step 1. Check the thermostat. Is it set to the right setting? Is it on “heat” and turned on?
Step 2. Check the furnace switch Make certain it’s on the “on” position.
Step 3. Check your furnace’s circuit breaker trip. See if it tripped.
Step 4. Check the furnace filter. Could it be clogged? If it is dirty, replace it.
Step 5. Check the furnace’s front panel. Is it securely shut?
Step 6. Check the gas valve. Be certain that the gas valve is set to the “on” position.
Step 7. Check air ducts and vents. Are the air ducts blocked?
Step 8. Still not working right? It’s time to call a professional.
Depending on the problem with your furnace, this could cost anywhere between $100 and $1200, plus the diagnostic fee. It is common for homeowners to spend between $170 and $500. A furnace repair costs depends on a number of factors, including the furnace's type, whether it is still under warranty, what replacement parts it requires, and how long the repairs take to complete.
Every furnace must have an AFUE or Annual Fuel Utilization Efficiency rating. Why is that important? It rates the percentage of heat generated by a furnace from every dollar of fuel consumed. The AFUE will be displayed as a percentage. Let's say the AFUE is 90%. You will then get 90% of the energy you burned as fuel as heat in your home. About 10% of the energy will be lost through the chimney and other such places. When you purchase a furnace or boiler, you should buy one with the ENERGY STAR® logo. Having an efficient heating system is imperative when you live in a cold climate.
