A furnace is a heating system that uses natural gas, propane, oil, or electricity to heat your home. It’s an essential part of your home in the winter, and when it breaks down, you need to know how to fix it quickly and efficiently. 

This furnace repair guide will show you how to troubleshoot and repair common furnace problems. We’ll cover everything from pilot light issues to strange noises coming from your furnace. By the end of this guide, you should be able to fix most furnace problems on your own.

Why furnace problems happen and how to prevent them

Furnace problems usually happen because of one of two things: either something is wrong with the furnace itself, or something is blocking the furnace’s vents. 

The best way to prevent furnace problems is to have your furnace serviced by a professional once a year. This will help ensure that your furnace is running efficiently and that there are no potential issues that could cause problems down the line. 

In addition, you should also make sure that your furnace’s vents are clear of any debris or obstructions. If your furnace’s vents are blocked, it can cause a number of problems, including decreased efficiency and strange noises.

If you take these steps to prevent furnace problems, you’ll be less likely to have to deal with a broken furnace in the middle of winter. But if you do find yourself dealing with furnace problems, don’t worry! In most cases, they can be fixed relatively easily.

Problem 1: The pilot light won’t stay lit

If your furnace’s pilot light won’t stay lit, there are a few possible causes. First, check to make sure that the gas valve is turned on. If it is, then the problem may be with the pilot light itself. Try cleaning the pilot light with a wire brush and then relighting it. 

If the pilot light still won’t stay lit, there may be a problem with the furnace’s thermocouple. The thermocouple is a safety device that turns off the gas if the pilot light goes out. If the thermocouple is defective, it may need to be replaced. 

Problem 2: The furnace is making strange noises

If your furnace is making strange noises, it could be due to a number of different issues. First, check to make sure that nothing is blocking the furnace’s vents. If the furnace’s vents are blocked, it can cause the furnace to make strange noises as it tries to force air through the obstruction. 

Another possible cause of furnace noise is a loose blower wheel. The blower wheel is located near the furnace’s motor and helps move air through the furnace. If the blower wheel is loose, it can cause a rattling noise. Tighten the bolts that hold the blower wheel in place to fix this problem.

Problem 3: The furnace isn’t blowing hot air

If your furnace isn’t blowing hot air, the first thing you should check is the furnace’s filter. A dirty filter can restrict air flow and cause the furnace to blow cool air. Replace the filter with a new one and see if that solves the problem. 

If the furnace is still blowing cool air, there may be a problem with the furnace’s blower motor. The blower motor is responsible for moving air through the furnace. If it is not working properly, it can cause the furnace to blow cool air. Try resetting the furnace’s circuit breaker and see if that solves the problem.

Finally, if the furnace is still blowing cool air, there may be a problem with the furnace’s thermostat. Make sure that the thermostat is set to “heat” and that the temperature setting is above the current room temperature. 

Looking for a furnace repair company

When you’re looking for a furnace repair company, it’s important to find one that is experienced and reputable. One way to do this is to ask for recommendations from friends or family members who have used a furnace repair company in the past. 

Another way to find a good furnace repair company is to search online. Read online reviews from customers who have used the company’s services in the past. This will give you a good idea of what to expect from the company. 

Once you’ve found a few furnace repair companies that you’re interested in, contact them and ask for quotes. Be sure to ask about the cost of labor and parts, as well as any warranties that the company offers. This will help you compare the different companies and choose the one that is right for you.
