Top 5 Common Furnace Problems and How to Fix Them

The furnace is your home’s primary source of heat, so it should be functioning properly to keep your family comfortable. But over time, furnaces can run into trouble due to normal wear and tear, improper maintenance, and other factors. To get the most out of your furnace and extend its life, it’s important to understand the common furnace problems and how to fix them.

Problem 1: The Furnace Won’t Turn On

The most common issue that homeowners face when it comes to their furnace is when it won’t turn on. If you’ve tried checking the thermostat and power switches, but the furnace still won’t fire up, then it’s time to check a couple of other things.

The first step is to check the pilot light, especially in older furnaces. Depending on your specific model, the pilot light should be either blue or yellow. To ignite the light, you’ll need to manually press the reset button and use a lighter to light the flame.

If the pilot light does not light, then it’s likely that your furnace’s filter may be clogged, so check to make sure it’s still clean. If the filter isn’t the problem, then it could be due to an electrical fault, so it’s best to have a professional technician look at your furnace to determine the cause and recommend the best course of action.

Problem 2: The Furnace Won’t Provide Enough Heat

If you feel like your furnace isn’t providing the right amount of heat, the problem could be due to a few things. For example, the air filter may be clogged, as mentioned previously, so make sure it’s still clean and replace it if need be.

Alternatively, the furnace blower motor may be having trouble, especially if it is stuck in the “on” position. In this case, you will want to turn the power off to your furnace to prevent any additional wear and tear. The blower motor, fan belt, and capacitor will all need to be calibrated properly to get the furnace up and running again.

Problem 3: Excess Noise from the Furnace

Strange noises coming from your furnace can be quite alarming and disconcerting, so it’s best to address them quickly. If your furnace is producing loud banging or rattling sounds, that could be a sign that the belt is loose or worn out and needs to be replaced. Other noises could indicate an issue with the blower motor or loose screws, but it’s best to have an expert come out to check it out first.

Problem 4: Excessive Carbon Monoxide Production

High levels of carbon monoxide (CO) in your home can be extremely dangerous, especially if it gets to dangerous concentrations. If you notice that the carbon monoxide level in your home is higher than it should be, then it could be due to a leak in your furnace.

If you have an older gas furnace, then it’s likely that the heat exchanger is failing or is not up to code, allowing CO to seep into your home. It’s highly recommended that you have a professional examine your furnace and recommend the necessary repairs to ensure that it is working properly and is not emitting CO.

Problem 5:Uneven Heating

If you notice that some rooms in your home are significantly warmer than others, then it’s likely that there is an issue with the furnace. This could be due to an obstruction in the air ducts, as well as an uneven airflow that prevents some rooms from receiving the heat they need.

In order to resolve this issue, you’ll need to do a thorough inspection of your air ducts to ensure they are free of obstructions, and determine if any other adjustments need to be made to the airflow. It’s best to consult with a professional technician to ensure that your furnace is functioning properly and all of the air ducts are clear.

These are just some of the common furnace problems that you may encounter, and while some of them are simple and easy to resolve, others require the services of a professional, so it’s important to know when to call an expert.

Furnaces are an essential part of any home’s comfort level, so it’s important to take good care of it and understand the common furnace problems to ensure that you get the most out of your heating system. With the proper maintenance and care, your furnace can continue to provide you with reliable and efficient heating performance for years to come.

Common furnace problems

1. Routine maintenance: Regularly having a HVAC technician inspect and maintain your furnace can help prevent common furnace problems. A technician will perform a thorough inspection of the system, cleaning any built-up dirt, dust, and debris in the furnace. They can also recommend any necessary repairs before a larger problem develops.

2. Change the air filter: It is important to check and change your air filter regularly. A clogged air filter can lead to increased energy costs as the system works harder to circulate air. It also increases the risk of system failure, due to the added strain on the motor. It is recommended to replace your filter once a month or depending on the manufacturer’s or technician’s recommendations.

3. Check the thermostat: Make sure your thermostat is functioning correctly and that the temperature is set correctly. The thermostat should be set at a comfortable temperature, typically somewhere between 70 and 78 degrees Fahrenheit. Additionally, a malfunctioning thermostat can lead to other furnace problems.

4. Check for leaks: Look for any visible signs of water or refrigerant leaks, as these can lead to other issues. If you find any signs of leaking, notify a technician as soon as possible for repairs.

5. Clear the area around the furnace: To ensure proper air flow and furnace efficiency, make sure that all vents, air intakes and air registers are clear from any furniture, carpets or stored items. Additionally, make sure there is nothing blocking or obstructing the unit.

6. Check the gas connections and safety shut-off valve: Make sure the gas connections and safety shut-off valve are securely connected and in working condition. If you notice any loose connections or valves, contact a technician immediately to repair the part.

By following these recommendations, you will help reduce the risk of common furnace problems and maintain your system in good condition. Without proper preventive action, furnace issues can become costly and lead to further complications. Regular inspection, maintenance and cleaning are the best ways to maintain a healthy system and prevent common furnace problems.
