Most Common Furnace Problems 

There are a few common problems with furnaces. The seemingly impossible issue you're having with your heater is simple to resolve. Check out the most common furnace problems that you may face.

Dirty Ductwork

As simple as this repair appears, everybody must be aware of it. Dust and debris might creep into your heating ducts from time to time. This reduces the amount of hot air that enters the room. If you've noticed that your furnace isn't heating the house as well as it used to, your ductwork may need to be cleaned. You can test the airflow by putting your hand in front of the vents and feeling how much air is coming out. Set up a once-a-month maintenance plan with a trusted HVAC professional to avoid problems in the future. We'll be able to clean out your ductwork and the rest of your HVAC system, allowing you to keep your heat on.

Old Filters

With the help of the filter in your furnace, you can maintain clean air and ductwork. Allergens, dirt, and other airborne contaminants can't make it past your filter.

While most property owners know that their furnaces require filters, only some know how often you should replace them. Whether or not a filter needs to be replaced every month or two depends on the filter's specifics. Refer to the filter's packing for a more precise time frame.

If your furnace isn't producing the required heat, it could be a sign that you need a new filter. A dirty filter may also cause your furnace to work harder than necessary. When the filter gets too full, the furnace has a harder time pulling air through it.

Faulty starting mechanism

Every furnace contains a mechanism that kicks off the heating cycle. The furnace determines the type of mechanism. This is commonly a pilot light in older furnaces. Instead of pilot lights, newer furnaces often use electrical ignitions.



The ignition or pilot light in your furnace can fail, and we may need to replace or repair it. When your ignition or pilot light fails, your furnace may stop turning on and heating your home. The pilot light may be visible within the furnace. If your furnace isn't turning on when it should, contact an HVAC technician.

Broken blower components

Your furnace has a blower that moves heated air through the ducts to keep your home warm. If you've noticed that your furnace isn't blowing hot air anymore, a few things need to be fixed.

We replace blower bearings – The set of ball bearings is one component of the blower mechanism that can fail. Ball bearings can wear and tear over time. If fitted incorrectly, they could be damaged. A scraping sound from your furnace is a sure symptom of a problem with your blower bearings. If you hear this noise, call an HVAC repair person immediately so we can replace your bearings. Keep in mind that running your furnace will further harm the bearings. Turning off your furnace is a good idea to keep the situation from worsening.

We replace the blower belt – As previously stated, your furnace uses a blower to force heated air into your home. The ball bearings are not the only component of that blower that can fail. One common problem is a malfunctioning blower fan belt. You'll know something is wrong when you hear a high-pitched shriek from the furnace.

Numerous issues might arise with your blower belt. The belt may slip out of place, and an HVAC professional may merely need to reposition it. In other circumstances, your blower belt will deteriorate over time and eventually snap. If this occurs, we will need to replace the belt.

Either of these issues can reduce the efficiency of your furnace. You will need more heat, and your inefficient furnace will cost you a lot of energy bills.

We replace the damaged blower capacitor—the powerhouse that turns on the blower motor. It functions similarly to a battery, releasing amps of energy to run the system.

The motor must rely on the circuit board for energy if the capacitor fails. This results in a burst of power. It has the potential to trip the breaker or cause a short circuit. A broken blower capacitor is commonly the cause of a furnace that begins but then stops. The good news is that an HVAC technician can look at the damage and decide if a replacement is needed.

Malfunctioning Heat Exchanger

You've probably never heard of it, but trust us when we say you're grateful for your furnace's heat exchanger. A coil of heated tubes serves as the heat exchanger. Your furnace warms the air in your home as it moves through these heated tubes. In other words, here is where all the heat in your furnace originates.

With the heat that tubes can withstand, regular furnace maintenance is required to keep them in good condition. If you do not, they may crack or malfunction. Our specialists will certainly need to replace your heat exchanger if this occurs. This is one of the most expensive repairs you might need to make, but it's still cheaper than buying a new furnace. 

The heat exchanger could be the culprit if you observe that air escaping from your vents isn't extremely warm.

When the temperature drops outside, your house should be a warm and inviting place to be. A broken furnace might quickly deprive you of that coziness. You may learn what to look for and narrow down what is wrong with your furnace by studying the common furnace repairs listed above.

You can also see why you need a regular maintenance plan for your furnace when it's hot and cold. Remember that the information provided above is only a guideline.
