Common Furnace Issues We Deal With
No Heat or Insufficient Heating
A failing ignitor, faulty flame sensor, or clogged burners can cause heat loss. We inspect gas valves, heat exchangers, and pilot assemblies to restore your furnace's heating efficiency.
Unusual Sounds
Grinding, banging, or whistling noises indicate worn blower bearings, loose belts, cracked heat exchangers, or air pressure issues. Our team identifies and resolves these problems before they worsen.
High Energy Bills
A malfunctioning limit switch, dirty filters, or poor airflow forces your furnace to work harder, increasing energy costs. We optimize blower performance, ductwork, and thermostat settings for efficiency.
Strange Odours
A musty smell signals moisture buildup, while a burning odour can indicate overheating components. Rotten egg smells suggest a gas leak, requiring immediate inspection and repair.
Thermostat Malfunctions
Inaccurate temperature readings often stem from sensor misalignment, corroded wiring, or a failing relay switch. We troubleshoot Wi-Fi, programmable, and standard thermostats for accurate heating control.
Cold Spots in the House
Uneven heating can be due to clogged ducts, failing blower motors, or incorrect furnace sizing. Our team inspects air distribution, damper settings, and return vents to balance heat throughout your home.
Furnace Keeps Cycling On and Off
Short cycling is caused by a dirty flame sensor, overheating heat exchanger, restricted airflow, or a faulty pressure switch. We perform a thorough system check to ensure stable furnace operation.
Frozen or Faulty Heat Exchanger
A cracked heat exchanger can leak carbon monoxide, while a frozen one restricts heat transfer. We inspect for blockages, corrosion, and temperature imbalances to keep your system running safely.
Gas Leaks or Carbon Monoxide Concerns
A faulty gas valve, loose fittings, or blocked venting system can lead to hazardous leaks. Our experts perform gas pressure tests, combustion analysis, and CO detector checks for your safety.
Heating Done Right
No Matter the Furnace Type, We Can Fix It!
Gas Furnaces
Gas furnaces rely on burners, gas valves, and heat exchangers for combustion. We diagnose and repair pilot light issues, faulty thermocouples, pressure switch failures, and carbon monoxide leaks.
Electric Furnaces
Electric furnaces use sequencers, heating elements, and blower motors to generate heat. Our experts troubleshoot burnt-out heating coils, failed relays, and malfunctioning high-limit switches.
Oil Furnaces
Oil furnaces require nozzle adjustments, combustion chamber cleaning, and fuel pump maintenance. We fix clogged filters, ignition transformer failures, and issues with the draft regulator.
Propane Furnaces
Propane furnaces operate similarly to gas models but require pressure regulators, orifice adjustments, and pilot safety checks. We handle burner misfires, gas leaks, and heat exchanger maintenance.
Dual-Fuel (Hybrid) Furnaces
These furnaces switch between gas and electric heating for efficiency. We recalibrate control boards, repair reversing valves, and optimize thermostat settings for seamless fuel transitions.
Modulating Furnaces
Modulating furnaces adjust heat output in small increments for precision heating. We service modulating gas valves, ECM blower motors, and advanced control systems for optimal comfort.
Two-Stage Furnaces
Two-stage furnaces use low and high-fire settings for energy efficiency. Our team inspects dual-stage gas valves, variable-speed blowers, and ignition systems to ensure smooth operation.
Single-Stage Furnaces
Single-stage furnaces run at full capacity whenever turned on. We troubleshoot worn-out ignitors, dirty burners, and airflow restrictions to maintain consistent heating performance.
High-Efficiency Furnaces
These furnaces use secondary heat exchangers and sealed combustion to maximize efficiency. We service condensation drain lines, variable-speed fans, and venting systems to keep them running efficiently.

Frequently Asked Questions
What is the most common problem of a furnace?
The most common furnace issue is restricted airflow due to clogged air filters, leading to overheating and system shutdowns. Other frequent problems include ignition failures, faulty thermostats, and blower motor malfunctions. Regular maintenance helps prevent these issues.
What is the most expensive repair on a furnace?
A cracked heat exchanger is one of the costliest furnace repairs since it can lead to carbon monoxide leaks and often requires a full replacement. Other expensive repairs include blower motor replacements, faulty circuit boards, and gas valve failures.
Why is my furnace not kicking on for heat?
A furnace may not start due to a malfunctioning thermostat, tripped circuit breaker, faulty ignitor, or gas supply issues. A dirty flame sensor or pressure switch failure can also prevent ignition. A professional inspection can pinpoint the exact problem.
Are furnace parts expensive?
The cost of furnace parts depends on brand and complexity. Common parts like filters, flame sensors, and ignitors are affordable, while blower motors, control boards, and gas valves can be costly. Proper furnace maintenance helps extend component lifespan.
What is the life expectancy of a furnace?
A well-maintained furnace typically lasts 15 to 20 years. High-efficiency furnaces may require heat exchanger or control board replacements sooner, while standard models can exceed 20 years with regular servicing.
Do you offer furnace installation and maintenance along with repairs?
Yes! In addition to expert furnace repair, HVAC Group provides professional furnace installation and routine maintenance services in Mississauga and surrounding areas. Whether you need a new energy-efficient furnace installed or regular tune-ups to keep your system running smoothly, our certified technicians are here to help. Contact us today for reliable heating solutions!
Will a new furnace lower home insurance?
A modern, high-efficiency furnace with advanced safety features may help lower insurance costs by reducing fire hazards, carbon monoxide risks, and gas leaks. Many insurers offer discounts for updated HVAC systems.
Is it worth fixing a 20-year-old furnace?
If a 20-year-old furnace requires frequent repairs or has low efficiency, replacing it with a new energy-efficient model is often a better investment. However, if repairs are minor—like an ignitor or flame sensor replacement—fixing it may still be worthwhile.
How often should I schedule furnace maintenance?
Annual furnace maintenance is recommended to ensure efficient performance, prevent breakdowns, and maintain indoor air quality. Regular servicing includes burner cleaning, heat exchanger inspection, gas pressure testing, and thermostat calibration.
What are signs that my furnace needs repairs?
Signs include uneven heating, rising energy bills, loud noises, weak airflow, frequent cycling, and a yellow pilot flame. Burning odours, gas smells, or carbon monoxide alerts require immediate professional attention.
Do you offer emergency furnace repair?
Yes, we provide 24/7 emergency furnace repair services across the GTA. Our certified technicians quickly diagnose and repair ignition failures, heat exchanger cracks, gas leaks, and complete system shutdowns to restore safe heating.
