- Cleaning and lubrication: To minimize friction and improve performance, the technician will, if necessary, clean parts and oil components that move.
- Electrical system checks: The functionality of all electrical connections and controls will be checked. Performance might be affected, and safety hazards may be created by loose or damaged connections.

What are some signs that my furnace might need to be repaired?
To avoid malfunctions and make sure your heating system operates well, it’s crucial to recognize the warning signs that your furnace might require repairs. Here are some typical indications that your furnace isn’t working as it should be:
- Reduced heat output: If your furnace is having difficulty heating your home like it once did, there may be a problem with the burner, heat exchanger, or other part.
- Heating inconsistency: If your home’s heating is unreliable, with some areas feeling significantly colder than others, this may be an indication of ductwork problems, a broken blower, or a blocked air filter.
- Strange sounds: Unusual noises like banging, popping, rattling, or screeching may be a sign that the blower, motor, or other internal parts are malfunctioning.
- Increased bills: Unexpectedly high heating costs without a clear cause, such as frigid weather, may be a sign of a malfunctioning furnace.
- Frequent cycling: Your furnace’s efficiency may suffer if it cycles on and off more often than usual. This can be the consequence of problems with the thermostat, a filter that is blocked, or poor airflow.
- Issues with the pilot light: If the pilot light constantly goes out or turns yellow instead of blue, there may be a problem with the burner or gas supply.
- Strange smells: Strange odours like burning, musty, or rotting egg scents might signify a variety of problems, including mildew in the ducts, excessive heat, or a gas leak. For safety, these should be taken care of right away.
- Weak or no airflow: A broken blower or a clogged air filter may be the cause of weak or nonexistent airflow from your vents.
- Excessive dust and dirt: A dirty or blocked furnace filter could be the cause of a sudden increase in dust and dirt in the area around your home.
- Problems with the thermostat: If your thermostat is unresponsive or fails to maintain the appropriate temperature, it may be broken or miscalibrated.
- Frequent repairs: If your furnace is growing old or you find yourself needing repairs regularly, it can be less costly to think about replacing it instead of spending money on repairs all the time.

Why is my furnace not working?
There could be a number of causes for your furnace to malfunction, including the following that should be promptly diagnosed and repaired in order to prevent further damage:
- Thermostat malfunction: Problems with the thermostat could include incorrect thermostat settings, low batteries, or faults that prevent the thermostat from sending out heating orders.
- Blocked filters: A filter that is clogged or dirty can impede airflow, resulting in decreased efficiency and overheating, which forces the furnace to shut off safely.
- Ignition problems: Problems with the ignition system or pilot light may prevent the furnace from igniting and generating heat.
- Issues with the gas supply: Gas supply problems, such as a gas valve shut-off, an issue with the gas Line, or a gas Leak, may stop the furnace from running.
- Blower motor malfunction: A malfunctioning blower motor might prevent warm air from circulating around your home.
- Electrical problems: The functioning of the furnace may be hampered by problems with electrical wiring, breakers, or control boards.
- Blocked flue: A clogged flue or blocked vents can inhibit the normal exhaustion of combustion gases, which can result in safety shutdowns.
- Limit switch tripped: If the furnace senses overheating, which is frequently caused by insufficient circulation or a filthy air filter, a high-limit switch can turn it off.
- Dirty burner: Burners that are dirty or blocked can result in insufficient combustion and excessive heat, which can cause the furnace to turn off.
- Ductwork problems: Leaky or clogged ductwork can restrict circulation and impact how heat is distributed.
- Flame sensor issues: Problems with the flame sensor could prevent the burner’s flame from being detected, which would cause the furnace to shut off.
- Wear and tear: Over time, a number of parts, including motors, belts, and bearings, can become worn out and need to be replaced.
- Age and poor maintenance: Issues are more likely to arise in older furnaces or ones that have a history of poor maintenance.

Why do I need to repair my furnace?
Problems with your furnace can appear minimal at first, but if left too long, it can lead to a myriad of damages that are costly and frustrating to deal with. Here is a closer look at why homeowners should aim to have their home’s furnace repaired as soon as possible:
- Restoring heat: A furnace’s main purpose in cold weather is to restore heat. Without a working one, you’ll feel uncomfortable and possibly be subjected to below-freezing conditions if your furnace isn’t functioning properly.
- Energy efficiency: A furnace that has been properly maintained and repaired uses less energy. When parts are malfunctioning, the furnace must work harder to generate the same amount of heat, which results in higher energy usage and more expensive utility bills.
- Safety: Some furnace problems can put your life in danger. For instance, a broken gas furnace could be leaking deadly carbon monoxide, a gas that has no odour or colour. Swift solutions can take care of dangers that are hazardous and avert future catastrophes that put your health and safety in danger.
- Extended lifespan: Your furnace’s lifespan can be increased with routine maintenance and prompt repairs. If issues are ignored, they can become more serious and necessitate an expensive replacement.
- Savings on costs: Minor repairs typically cost less than major replacements. Quick action can stop minor concerns from growing into more significant, expensive ones.
- Prevention of additional damage: If repairs are neglected, the furnace and nearby components may sustain more severe damage. This may cause a series of issues that are more difficult and expensive to solve.
- Protection under warranty: If your furnace is covered by a warranty, it may need routine upkeep and rapid repairs to keep the guarantee in effect. Failure to do this could result in the termination of your warranty.
- Comfort: Consistent warmth from a working furnace increases your comfort in the middle of winter.
- Health advantages: By reducing excessive cold and related health problems like hypothermia, a properly operating furnace contributes to a healthy home environment and indoor air quality.
As you can see, prompt repairs are absolutely essential in restoring your home’s comfort and ensuring the safety of your family. Therefore, if you think your current furnace isn’t operating as it should be, we encourage you to reach out to the team at M&K Heating and Air Conditioning to schedule a repair appointment with a member of our certified and experienced HVAC team.
