Troubleshooting Common Furnace Problems

When my husband and I purchased our first home, the process was stressful, but we settled on one we liked enough to live in temporarily until we expanded our family. When moving time arrived, we both dreaded the expected stress. We ended up using a different real estate agent than we did the first time, and we made a great decision, because she had a lot of home remodeling knowledge! We were adamant on finally finding our "perfect" home this time. When she showed us homes that lacked features we desired that we would have "nixed" before, she let us know if the feature could be added, and usually it could! We are now in our new home that we had a few small renovations performed on after we bought it, and we love it! I want to help others by sharing some remodeling tips I learned on a blog!

Troubleshooting Common Furnace Problems

There are few things in this world that are worse than waking up on a cold winter morning to find that your furnace is not working properly, or worse yet, not working at all. While your first instinct may be to pick up the phone and call your HVAC contractor, you should know that professional intervention may not be necessary. This is because many of the most common furnace problems can be fixed with just a few minutes of troubleshooting. Below you will learn more about how you can go about troubleshooting a few of these common issues.

Problem: Furnace Is Not Producing Enough Hot Air

If the air coming from your heating vents is not quite as powerful as it once was, you may find it virtually impossible to maintain a comfortable temperature inside your home. The good news is, this problem is often quickly fixed by simply replacing the air filter on your furnace. This is because a dirty air filter will eventually prevent your furnace from being able to pull in enough cold air. Since your furnace can only put out as much air as it is able to take in, this problem can quickly result in reduced air pressure from your vents.

After replacing your furnace's air filter with a clean filter, simply wait a few minutes and see if the air pressure improves. If it does not, you will need to contact your HVAC contractor to have the inside of your furnace cleaned and inspected, as debris from your dirty filter may have clogged your air intake vent.

Problem: Furnace Won't Turn On

Many people automatically go into panic mode when they discover that their furnace is not turning on. However, you may be surprised to learn just how simple the solution to this problem often is.

The most common reason for a furnace to stop turning on is that it simply is not getting any power. This is often the result of a tripped circuit or blown fuse. Therefore, the first step you should take is to check both your main fuse box and the secondary fuse box located near your furnace to ensure all fuses are still in working order.

If your furnace is receiving power, the problem is likely with your thermostat. If you are using a traditional mercury thermostat, you will need to replace this unit. However, if you are using a digital thermostat, the solution may be as simple as replacing the batteries in this unit. A good indication that this is the problem will be a blank or faded display screen.

Contact a furnace repair service like D & R Service Inc if you can't figure out the problem.
