As furnaces age, they are more likely to malfunction due to worn-out parts. Old furnaces may also lead to uneven heating, decreased energy efficiency, and carbon monoxide leaks. A heating contractor can inspect your furnace to help you determine if it should be repaired or replaced. Here are some signs that it may be time to replace your furnace:
Unusual Noises
If furnaces are functioning correctly, they should operate quietly. Sudden changes in volume or type of noise can indicate an operational problem. Rattling or squealing noises often result from loose or malfunctioning components like the blower motor or fan belt. Banging noises usually signal an issue with the system’s heat exchanger or burners. Most noises are addressed with part replacement or repair. If sounds do not diminish or worsen after a repair, this could indicate irreparable mechanical issues and a replacement will be necessary.
Uneven Heating
If some rooms in your home are consistently hotter or colder than other rooms, your furnace may not be distributing heat effectively. This is caused by various issues, including:
- Failing blower motor
- Dirty air filters
- Blocked vents
- Malfunctioning thermostat
While most causes are easily fixed, recurring issues can indicate it is time for a replacement. Uneven heating might also result from a poorly sized furnace. A small furnace is usually not equipped to handle a two-story home, leaving some rooms upstairs under-heated. Schedule an in-home estimate with a heating contractor for assistance in selecting a new furnace that meets your home’s heating needs. Mr. Furnace offers mini-split systems with zoning capabilities to improve temperature control and make sure rooms are evenly heated.
Visible Wear and Tear
Cracks, corrosion, and rust are key indicators that a furnace should be replaced. Damage to the HVAC housing can lead to carbon monoxide leaks or decreased structural integrity. Corrosion can spread to the furnace’s circuit board, frying the wires or creating a fire hazard. Older furnaces may also struggle to burn incoming gas completely. This causes the pilot light to flicker or turn yellow. If you notice these signs of wear and tear, it is best to schedule inspection services quickly. We are available 24 hours and are prepared to service all makes and models to keep your home safe from carbon monoxide leaks and other hazards.
Frequent Repairs
Frequent breakdowns usually indicate that your furnace’s internal systems are wearing down. Though part replacement is available, new parts may place increased stress on worn parts, leading to further deterioration. Newer parts may also not be compatible with older HVAC systems and cause issues with system performance.
Continual repair costs add up quickly, potentially exceeding the value of your furnace. Certified HVAC technicians can estimate repair costs. If repairs total more than half the cost of your furnace, replacement is often recommended. Selecting a new furnace that comes with part replacement warranties can also help reduce repair expenses.
Decreased Air Quality
HVAC systems directly affect your home’s indoor air quality. They are designed to filter dust, pollen, and other debris from the air as it circulates through your home. Even with regular filter replacement, over time, a furnace’s ability to filter the air reduces. This can lead to increased cold or allergy symptoms. Many new furnaces have advanced filtration systems that filter out airborne particles long-term. Whole-home air purification systems can often be installed alongside a new furnace to better remove bacteria, mold, or odors from your home.
