Does your heater need some immediate attention?
If you are experiencing any issues with your home heating system, SERVKORE can be there ASAP to fix the problem.
Furnaces can experience a variety of problems, from minor glitches to major malfunctions. Some issues are simple to troubleshoot, while others require professional intervention. Here are some common issues homeowners might face with their furnace:
- No Heat: If your furnace isn’t producing heat, it could be due to a malfunctioning thermostat, a pilot light going out, or a tripped circuit breaker.
- Blower Runs Continuously: If the blower continues to run, it may be due to a stuck fan relay, a dirty air filter, or a malfunctioning thermostat.
- Unusual Noises: Rattling, banging, or whistling noises could indicate loose parts, duct issues, or airflow problems.
- Uneven Heating: Rooms that are too hot or too cold may suggest problems with the ductwork or a need for recalibration of the thermostat.
If your heater is underperforming in the colder temperatures, it probably needs some special attention. Please reach out to us to see how we can help your boiler get back to its full potential.

SOME COMMON ISSUES THAT YOU MAY BE EXPERIENCING:
1. Thermostat Issues
Your thermostat is the command center of your heating system. If it’s malfunctioning, it can cause your furnace to turn on and off erratically or fail to maintain a consistent temperature. Calibration issues, dead batteries, or electrical faults can affect its performance. In some cases, the problem may lie in the wiring, which could require a technician to replace or repair.
Signs of thermostat problems:
• Inconsistent room temperatures
• Furnace runs constantly or never turns on
• Thermostat not responding to temperature changes
• Display screen is blank or malfunctioning
2. Furnace Short Cycling
Furnace short cycling occurs when the system turns on and off rapidly, failing to complete a full heating cycle. This can waste energy, overheat the system, and cause premature wear on your furnace. Short cycling may be caused by a clogged air filter, a malfunctioning thermostat, or issues with the furnace’s internal components, such as the blower motor or limit switch.
Reasons for short cycling:
• Dirty or clogged air filter
• Overheating due to poor airflow
• Malfunctioning thermostat or control board
• Low gas supply
3. Dirty Air Filters and Their Impact
A clogged or dirty air filter can significantly impact your furnace’s performance. It restricts airflow, making your heater work harder to warm the space, which can lead to overheating or even system failure. Replacing or cleaning the filter regularly is one of the simplest and most effective ways to keep your furnace running smoothly. Depending on the type of filter and how often you use your heating system, this may need to be done monthly or at least every three months.
Signs that your air filter needs replacing:
• Dust buildup around the vents
• Increased dust in the air or on furniture
• Reduced airflow from the vents
• Higher energy bills due to reduced efficiency
4. Ignition Problems and Pilot Lights
If your furnace uses a pilot light, it’s important to make sure it’s lit properly. A malfunctioning pilot light can prevent your furnace from igniting, leaving your home without heat. Common causes for this issue include a dirty pilot light, a faulty thermocouple, or a gas supply issue. Modern furnaces, however, often have an electronic ignition system. If this system fails, it can lead to problems with the furnace’s operation as well.
If you’re experiencing ignition issues:
• Check to ensure the thermostat is set properly
• Inspect the pilot light (if applicable) or ignition system for faults
• Ensure there is no gas shutoff or leak
When to Call a Professional
If your furnace isn’t working properly despite your efforts to troubleshoot, or if you notice any unusual odors, noises, or performance issues, it’s best to call a certified HVAC technician. They can perform a thorough inspection and pinpoint the cause of the problem. Some issues, like gas leaks or electrical faults, can pose safety risks and require expert repair. Timely professional service can prevent minor issues from becoming major—and potentially expensive—problems. Regular maintenance and prompt repairs can extend the life of your heating system and keep your home warm and comfortable year-round.
