How to Tell When Your Furnace is Beyond Repair

If you’ve been having problems with your furnace, you might wonder whether it’s time to call a professional to take a look at it. Luckily, there are a few common signs that indicate when it’s time to stop trying to furnace repair and just have it replaced. These signs include leaks, noises, and Carbon monoxide.

Noises

It is important to recognize that there is a difference between the normal furnace noises and the ones that indicate a problem with the equipment. If the noise is loud and is coming from your blower motor or the system itself, then you should take action.

A high-pitched squealing sound is typically the sign of a loose fan belt. If the squealing sound is intermittent, it may be caused by a blower wheel that is loose. If the noise is a continuous one, the belt might need to be replaced.

A rattling sound is a symptom of an unbalanced blower wheel or a motor bearing issue. If this noise happens at a constant pace, it could be a sign of a problem with your heating system.

A scraping noise is a signal of an unbalanced blower wheel, blower bearing or a faulty blower motor. If you hear a scraping sound, then you will want to contact a professional to determine the cause of the noise.

Carbon monoxide

If you are worried that your furnace might be leaking carbon monoxide, you can do a test to see if it is a problem. This gas is a common byproduct of burning natural gas in your furnace.

Although it is odorless and tasteless, it can be dangerous. It can cause dizziness, vomiting and even death. If you suspect a leak, contact a professional immediately.

One way to detect a carbon monoxide leak is to check the flue. The flue is a round pipe that exits your home through the roof. It should be clear of debris. If there is a lot of soot or rust around it, this could be an indicator.

You can also use household bleach to test your furnace for a carbon monoxide leak. Simply dip a piece of paper in the bleach and hold it to the draft inducer. If the draft inducer stops working, you are likely leaking CO.

Leaks

When you have a furnace, it is important that you maintain it properly. However, over time, a problem can occur, requiring a technician to repair it. Getting it repaired quickly can help prevent future problems and keep you warm.

Aside from the obvious signs that your furnace is malfunctioning, you should also be on the lookout for signs that it’s time to replace it. Some signs include constant drafts, a leaking furnace, and higher than normal energy bills.

A puddle or condensation on the outside of your furnace is a sign that your condensate line is malfunctioning. This can cause mold, mildew, and damage to your floors and walls. When you first notice the problem, it’s a good idea to turn off your furnace and call a technician.

A steamed window or frosty surfaces are other signs that you may have carbon monoxide in your home. This is a odorless, tasteless gas that can be present in your home if the chimney does not draft upward.

Cost of repair or replacement

If your furnace isn’t functioning properly, you may need to furnace repair or replace it. This can be an expensive job, though. The cost of repair depends on several factors. First, the model of the furnace. Next, the cost of parts and labor.

The furnace can either be electric or gas. Generally, electric models don’t have a heat exchanger. In addition, a gas furnace is more complicated to repair.

The average cost of a furnace repair or replacement is $150 to $600. The size and age of the furnace can also affect the price. If the unit is less than 10 years old, it’s advisable to invest in a new one. If you have an older furnace, however, you might need to make major repairs.

The most common type of repair is for a furnace ignitor. A bad ignitor can cause your furnace to shut down. A flame sensor is another common component that needs to be repaired. This is a metal rod that sits in front of the furnace’s flame. If it’s dirty, it can short cycle and cause problems.
