If you’re a homeowner in Vacaville, CA, you know the importance of keeping your furnace in good working condition.

1. One of the most common signs that your furnace needs repair is strange noises from the unit.

Facts About Furnace Repair

If you are hearing weird noises more than usual, it might be time to call in a professional to take a look at your furnace. There could be something wrong with it, and getting it fixed as soon as possible is important. Not only will this save you money in the long run, but it will also keep you and your family safe and comfortable during the winter months.

2. Another common issue is strange smells coming from the furnace.

If you notice a burning smell, it could be a sign of an electrical problem. If you smell natural gas, this is an emergency, and you should evacuate the premises immediately and call your gas company. If you have an oil-burning furnace, sometimes a sulfur smell is typical, but if it’s accompanied by soot, that could signify a problem. If unsure what the scent is, it’s always best to avoid caution and contact a professional.

3. Furnaces can also stop working properly if they're not getting enough power.

Check the circuit breaker to see if it’s been tripped. If it has, flips it back on and see if the furnace starts working. If not, check to see if there’s a power outage in your area. If there is, wait until the power comes back on before trying to use the furnace again. The problem may be with the furnace itself if there’s no power outage and the circuit breaker is fine. In that case, you’ll need to call a professional to come to take a look at it.

4. Your furnace suddenly starts blowing cold air.

If your furnace suddenly starts blowing cold air, there is likely something wrong with the furnace, and you will need to call a technician to come and fix it. The technician will be able to determine what is wrong with the furnace and will likely be able to fix it fairly quickly. In the meantime, you can try to troubleshoot

the problem on your own by checking some of the most common causes of this issue.

One possible cause of a furnace blowing cold air is that the filter needs to be replaced. The filter keeps dirt and dust from entering the furnace and clogging up its workings, so if it’s dirty or clogged, the furnace won’t be able to generate heat properly. To check if the filter needs to be replaced, take it out of the unit and hold it up to the light. If you can’t see through it, it’s time for a new one.

Another common cause of a furnace blowing cold air is that something is blocking or obstructing airflow within the unit. This could be caused by anything from built-up dust or dirt to a bird’s nest built inside the vent. If you suspect something obstructs the airflow, try cleaning out any visible dirt or debris and then recheck the airflow. If it’s still not flowing correctly, you’ll need to call a technician to take a look.

5. If your furnace doesn't seem to be blowing any air at all.

If your furnace doesn’t seem to be blowing any air, you may have a problem with your hands. A lack of airflow could mean the furnace is not working correctly, and you’ll need to get it fixed as soon as possible. There are a few things you can do to troubleshoot the problem yourself, but if you’re not sure what’s wrong or you can’t fix it, you should call in a professional.


The first thing to do is check the filter. The filter keeps dust and dirt from getting into the furnace and causing problems, so if it’s dirty, the furnace won’t be able to work correctly. If the filter looks clean, move on to step two.


Next, check the ducts. Make sure they’re clear of any debris or obstructions and that they’re connected properly. If everything looks good there, move on to step three.


The next step is to check the thermostat. Ensure it’s set to “heat” mode and turned up high enough for the furnace to kick on. If everything looks good so far, go ahead and turn off your furnace at the breaker box and wait about five minutes before turning it back on again. This will reset the furnace and see if that solves the problem.


If your furnace still isn’t working correctly after following these steps, then it’s time to call in a professional. A qualified technician will be able to diagnose the problem and get your furnace up and running again in no time.

6. Another severe issue is a cracked heat exchanger.

A cracked heat exchanger can be a severe issue for a homeowner. Not only will it reduce the efficiency of your heating system, but it could also lead to dangerous carbon monoxide buildup in your home. If you suspect that your heat exchanger is cracked, it’s important to have it inspected by a professional as soon as possible.

7. One way to prevent furnace problems is to have it serviced regularly by a professional.

A professional can clean and inspect the unit to ensure everything is in working order. This can extend the life of your furnace and prevent expensive repairs down the road. Be sure to schedule service at least once a year and more often if you have an older unit.

8. If you need to repair your furnace, it's important to use a licensed professional.

They will have the knowledge and experience to properly fix the issue while also ensuring your safety. Attempting to fix the furnace on your own could result in further damage or even injury.

So if you’re not confident in your ability to repair the furnace, it’s best to leave it to the professionals.

9. Furnace repairs can be costly, but they're often worth it to avoid more severe issues down the road.

Furnace repairs are often costly, but they’re worth it to avoid more severe and expensive issues down the road. A furnace that is not maintained correctly can cost a lot more money in the long run due to damage that may occur. You can avoid most of these potential problems by repairing your furnace regularly.

10. Remember that preventative maintenance is key to keeping your furnace in good condition.

Preventative maintenance is the best way to keep your furnace in good condition. This means that you should perform regular inspections and cleanings, regardless of whether or not there are any problems. By taking this proactive approach, you can avoid many common problems and extend the life of your furnace.
