Do you have a furnace that’s blowing cold air? If so, it’s time to call an HVAC technician for help. Here are six signs that indicate it’s time to furnace repair:

1. The Furnace is Blowing Cold Air

If you turn your heater on and your furnace is blowing cold air for an extended period of time, it is a sign that it’s time to call an HVAC technician! There are a few possible reasons for this problem, but the most likely explanation is that the furnace is no longer heating the air properly.

The furnace blowing cold air could be due to a variety of issues, ranging from simple things, like clogged air filters, to more serious problems, like faulty parts or worn-out belts. No matter what the cause, it’s something that needs to be fixed as soon as possible; otherwise, you’ll just be wasting money on your energy bills.

2. Your Furnace is Making Strange Noises

If your furnace starts making strange noises, it’s time to call a qualified HVAC technician. The strange noise could indicate a serious problem with your furnace that needs to be addressed immediately.

Putting off calling a technician could cost you more money in the long run, so it’s always best to err on the side of caution. That said, some furnace problems aren’t as serious as others. If you’re handy and reasonably comfortable working around high-voltage equipment, you might be able to troubleshoot the issue yourself.

3. The Furnace Isn’t Turning On At All

There are a few possible reasons why your furnace may not be turning on. First, check to make sure that there is power running to the furnace. If the furnace is plugged into an outlet, check to see if there is a switch next to the furnace that needs to be turned on.

If no power is running to the furnace, you’ll need to contact an electrician. Another possible reason your furnace isn’t turning on is that the pilot light may be out. If this is the case, you’ll need to relight the pilot light.

Instructions for doing this can usually be found in the owner’s manual for your furnace. If neither of these solutions works, it’s probably time to call a furnace repair technician. They will be able to diagnose the problem and get your furnace up and running again in no time.

4. Your Energy Bills Have Skyrocketed Suddenly

It’s time to call in a technician when your energy bills start creeping up, but there are a few things you can do yourself first. A lot of the time, an increase in energy bills is simply due to the weather.

When it’s cold outside, your heater has to work harder to keep your home warm, and when it’s hot outside, your air conditioner has to work harder to keep you cool. If your bills are always highest in the winter or summer, then it might just be the weather causing them to go up. Another thing that can cause your furnace to use more energy is if the furnace filter is dirty.

5. You See Water Around The Furnace

When you see water around the furnace, it’s time to call an HVAC technician. This is not something to be taken lightly, as water can cause all sorts of damage to your home and furnace.

If you see water around the furnace, it’s important to turn off the power to the unit and call a technician immediately. Don’t try to fix things yourself, as this could result in further damage and even an electrical shock. The technician will be able to determine what’s causing the leak and will take steps to repair it. Leaks can be caused by several things, from a faulty seal on the door of the furnace to a problem with the pipes or coils.

6. The Furnace Smells Strange

If you’ve ever gone to turn on your furnace after it’s been sitting idle for a while and get a whiff of something strange, you’re not alone. It turns out that this is a pretty common problem and one that can be indicative of a serious issue with your HVAC system.

When your furnace is operating normally, it should emit very little in the way of fumes or odors. If you start to notice strange smells coming from your furnace, it’s often an indication that something isn’t burning correctly.

This could be due to a buildup of dirt and debris in the burners, or it could be indicative of a more serious problem, like a cracked heat exchanger

Bottom Line

If your furnace is giving you any of these 6 signs, it’s time to give an HVAC technician a call. Trying to fix it yourself could result in further damage or even injury. It’s always better to be safe than sorry when doing furnace repair and replacement!
