10 Common Signs That You Need a Furnace Repair
Hot Air and Improper Air Circulation
Various furnace issues can cause improper air circulation, but it is most important to contact a professional as soon as possible. Whether it is a broken flame sensor or a carbon monoxide leak, it is always wise to contact a professional immediately to prevent further problems and potential safety hazards.
An often-recognized problem in furnaces is their malfunctioning limit switch, which monitors their internal temperature and shuts them down if necessary to prevent fires, extensive damage, and other serious problems that should be handled by an HVAC technician like Green Street HVAC.
A failing limit switch must function perfectly to protect you from fires, extensive damages or other serious issues which require professional care from HVAC technician service personnel. Apart from every other benefit of proper circulation, the best one is that it can increase the lifespan of the furnace.
Cold Air Blowing
Furnaces should provide even heating to all rooms in your house; any hot or cold spots indicate something is amiss with your system. This could be caused by several issues, including a dirty air filter or an incorrect flame sensor, which could cause your heating cycle to turn off before completion. Yellow flames on your pilot light indicate that gasses aren’t burning hot enough. This can lead to carbon monoxide leaks, which pose serious health and safety hazards that an HVAC technician must immediately address.24 Hours a Day, 7 Days a Week.
Strange Smells Because of Dirty Filters
Furnaces that operate effectively should maintain clean and moist air in your home, providing optimal conditions for breathing. If your house feels stuffy or you notice allergies from dust, viruses, pollen or dander in the airborne particles that make up part of everyday life, your furnace may not do its job as intended.
If your carbon monoxide detector goes off, this could be another telltale sign of trouble with your furnace. Carbon Monoxide is a colorless and odorless gas which poses great threat to both you and your family’s well being – thus necessitating immediate action from professionals in order to rectify.
Uneven Temperatures and Humidity
When your home doesn’t heat evenly, it could be an indicator that the furnace requires repairs. This may be caused by issues like a clogged filter limiting airflow or leaky ductwork allowing heated air to escape uncontrollably.
Be sure to also inspect the breaker panel to see if the HVAC system switch has been tripped. If it has, this would prevent fuel from reaching its ignitor, an essential step in keeping your home warm and cozy.
Noises like rattling, humming and scraping indicate that your furnace requires repairs. Such sounds could be signs of loose belts, clogged filters or carbon monoxide leakage issues.
Compliance with Local Codes & Regulations
A professional AC installation company ensures that your AC system complies with local building codes and regulations, whether commercial or residential. Each area has specific requirements governing the installation of air conditioning systems to ensure safety and efficiency.
DIY installations may overlook these crucial regulations, leading to potential hazards and code violations. Local authorities often require permits for HVAC installations, and professional installers know how to obtain and adhere to these permits. Compliance with local codes ensures your installation’s safety and protects you from legal issues.
Increased Energy Bills
Your furnace should keep your home warm without using too much energy, but if your energy bill has increased unexpectedly without an increase in consumption, that could be an indicator that something is off with your system.
An unfamiliar scent that does not dissipate is another telltale sign of a malfunctioning furnace. The source could be anything from an air filter clogging up with dust to carbon monoxide leakage in your system.
Furnaces require maintenance to function optimally, and monitoring for signs of problems is key to keeping them functioning efficiently. By paying attention, you may catch small issues before they escalate into larger ones that require extensive repairs.
Strange Noises like Humming and Clicking
If your furnace seems to be cycling on and off more frequently than usual or making noise that sounds like an electrical fire, this could be a telltale sign that it requires maintenance or repairs. A dirty air filter or problems with the thermostat could be to blame.
Humming, clicking, rattling, and scraping indicate heating equipment repair needs. Each of these typically points to various issues within your unit.
Tripped Circuit Breakers
An unreliable furnace can be both inconvenient and potentially hazardous. An unexpected increase in your heating bill without an equal increase in usage could indicate something needs to be fixed with your system; typically, this involves issues with your pilot light or thermocouple, which require professional evaluation for optimal functioning.

Faulty Thermostat Heat Exchanger
Your furnace system should distribute warm air evenly throughout your home when working correctly; if cold or hot spots exist, there could be an issue with its blower, ductwork, or vents that need to be addressed immediately.
When your thermostat remains set at the appropriate level but still cannot get your house warm, that should be another telltale sign that professional assistance should be sought immediately.
A strange smell or pilot light that changes color could also signal trouble with your heating system; fuel fumes could be present, or carbon monoxide could also cause these changes; either way, you should seek furnace repairs ASAP.
Carbon Monoxide Immission
Carbon Monoxide, or CO, is an odorless, colorless gas released during furnace combustion that can accumulate in your home if your system is malfunctioning improperly. A technician will test for carbon monoxide levels and address any potential sources that could be leading to CO leaks.
Regular maintenance of your system can reduce the risk of carbon monoxide leaks and ensure that all vents and flues remain clear of obstructions—steps that could save your family from potentially fatal carbon monoxide poisoning.
Harmful Gas Leak
If the gas supply valve gets a leak, it will release harmful gasses such as carbon monoxide (CO) into the air. CO is odorless and colorless, making it easier to detect with specialized equipment. Breathing in high levels of CO can cause symptoms ranging from headaches and dizziness to unconsciousness and even death.
To prevent these hazards, furnaces must be regularly maintained, including inspections for leaks. Installing carbon monoxide detectors in your home can also provide an early warning in case of a gas leak.
If you suspect a gas leak, it’s important to evacuate the area immediately and contact your gas utility provider or emergency services for assistance.
Conclusion
Maintaining a properly functioning furnace is crucial for the comfort and safety of your home. Recognizing the signs indicating the need for furnace repairs is essential in preventing potential hazards such as carbon monoxide leaks or system malfunctions. By staying proactive and attentive to the performance of your furnace, you can enjoy a warm, comfortable home while minimizing risks associated with heating system malfunctions.
