Michigan’s proximity to the Great Lakes creates periods of heavy snowfall, and its position in the middle of the polar vortex traps cold air in the region for months at a time. Old and aging Roseville furnaces are forced to work overtime and often show signs of inefficiency and premature wear and tear if not properly maintained.
A furnace can usually pass the basic maintenance startup test, but during a cold winter day, it can begin to fail, potentially leading to a complete breakdown during a snowstorm.
At C & C Heating & Air Conditioning, we help homeowners spot the early signs a furnace is failing in Roseville, MI, so we can replace a unit that will not last the winter.
If you realized that your furnace started behaving differently at the end of last winter, address the issue(s) before the next cold season begins. Inactivity will not cause the issue to resolve itself.
Your Furnace Is Reaching the End of Its Expected Lifespan
A furnace’s typical lifespan is 15 to 20 years, and that is with consistent maintenance tune-ups. Older furnaces that are already struggling to heat a Roseville home may run for multiple winters without a tune-up, making every successive winter a gamble.
Old furnaces in Roseville, MI also use more energy and fuel to turn into heat. Even if it keeps working, you are likely paying for it on your rising energy bills.
The Furnace Struggles to Reach the Thermostat Setting
If your furnace is struggling to reach the desired temperature, it means that it’s working harder than it should be. Possible reasons for this include:
- Clogged air filters
- A failing blower motor
- Worn burners
- An aging system that can’t keep up with current heating demands
A Michigan cold snap will make this furnace problem in Roseville more noticeable because the furnace is working hard against the cold temperature difference.
Your Furnace Runs for Long Periods Without Warming the Home
A furnace that continuously runs for long periods of time, but never fully warms a home, is another warning sign that your furnace is losing its heating output. This will also drive up your energy bill and wear down components more quickly.
Typically, a furnace should run for about 30 minutes during very cold Michigan weather, with five-to 10-minute breaks in between after the temperature is reached. In periods of extreme cold, it is normal for it to run continuously to make up for the temperature drop, but if it never reaches the desired temperature, this is a furnace problem during the Michigan winter that needs to be addressed.
Short Cycling Can Signal a Furnace Under Stress
Furnace short cycling in Roseville means the unit is turning off and on before reaching a complete cycle and repeats the same pattern over and over again. This signals your furnace is under stress, with possible culprits being:
- Clogged air filters
- Dirty flame sensors
- Overheating
- Restricted airflow
- Thermostat issues
Furnace short cycling wears out blower motor components quicker and, if left unchecked, will cause a full-on breakdown. If this happens and your furnace is not heating your Roseville home, protect your pipes from freezing and call C & C Heating & Air Conditioning for emergency support.
Weak Airflow Can Point to Blower or System Problems
If you’ve noticed that the airflow from your vents is weak, some rooms are getting barely any airflow, or your furnace is blowing cold air in Roseville, the issue can stem from:
- Failing blower motors
- Clogged air filters
- Restricted vents
- Ductwork issues
Weak airflow also puts strain on the furnace and can cause it to overheat and shut down. If replacing the air filter doesn’t work, call C & C Heating & Air Conditioning for a furnace troubleshooting inspection.
A blower fan that continues to run after the unit is turned off is normal to clear the remaining heat, but one that runs continuously needs to be looked at, as it can cause a full unit breakdown.
Cold Spots and Uneven Heating Can Signal Declining Performance
If some rooms have cold spots and stay chilly no matter what you do, this is a surefire way to know that your furnace is on the decline. Uneven heating is a common furnace problem in older units, especially if the furnace no longer has the capacity to heat the entire home.
Sometimes the issue is the blower motor or a duct sealing need, but it can also signal that this is the end of the furnace’s lifespan.
Banging, Rattling, Screeching, and Rumbling Should Not Be Ignored
Furnaces make some noise in Roseville, but they should never make continuous strange and loud noises if they are working properly. Any banging, rattling, screeching, or rumbling is a red flag, often indicating loose or overworked components. Every furnace making a noise should be looked at by a professional heating repair technician.
Repeated Ignition Problems Can Lead to a No-Heat Situation
An electric ignitor is one of the most common components to fail during a heavy winter scenario. It may click but produce no flame, or require several attempts to ignite. Luckily, if caught early, replacing a worn-down ignitor is an easy fix.
If it is ignored, this can quickly lead to a no-heat situation, and this is something you do not want during the freezing temperatures. If your furnace is not starting, but then eventually does after multiple attempts, it’s a sign your furnace will fail during winter.
A Yellow or Unstable Burner Flame Requires Attention
A healthy burner flame always glows blue, and anything else is a health risk. If you have noticed your flame is flickering or glowing yellow or orange, this means harmful carbon monoxide gas could be escaping from the furnace.
The fault could be from dirty burners or ventilation issues, or a failing heat exchanger, which is always a sign that the furnace needs replacement.
Rust or Corrosion Can Signal a Serious Furnace Problem
Rust flakes or corrosion on the furnace cabinet or streaks near the burners and ventilation components point to moisture or venting issues. These should never be ignored because they directly affect the heat exchanger, which is responsible for converting the fuel into heat and removing the carbon monoxide after the combustion process.
Soot by the cabinet also means incorrect combustion is happening, which also points to a heat exchanger issue.
Repeated Breakdowns Can Indicate an Aging Heating System
Every furnace failure or breakdown puts unwanted stress on major components and is a hit to the furnace’s heating output and efficiency. While some furnace repairs are OK, multiple breakdowns are a sign that your furnace is not working properly in Roseville.
Persistent Furnace Odors Can Reveal Developing Problems
There are three main furnace odors to be aware of:
- Mold or musty odors
- Burning odors
- Rotten eggs or sulphur smells
A persistent odor should never be ignored because it could point to the cause of another early sign that the furnace needs replacement in Roseville.
How to Know Whether Your Furnace Needs Repair or Replacement
If you are asking yourself, ‘Will my furnace make it through winter?’ there are chances it needs repairs or an entire replacement. Always factor in:
- The cost of multiple repairs over a few years.
- Unit age (15 to 20 years being the maximum).
- The cost of upcoming repairs adding to half the cost of a new unit.
- Asking for C & C Heating & Air Conditioning’s expert opinion, valued by hundreds of customers.
