Damaged Pilot Light

If your pilot light is damaged, it may not be properly lighting your furnace when it needs a flame. This means that your furnace is incapable of heating air because it is unable to light a fire, which would explain why your furnace is not working! There are many ways that your pilot light can be damaged. In our line of work, we often repair furnaces with pilot lights that have been put out, electronically disabled, or physically damaged from contact with another object. If you suspect that your pilot light may be damaged, reach out to Home Service Plus today for help diagnosing your furnace issues!

a furnace filter

Restricted Airflow

Restricted airflow is often the result of a clogged filter and can result in slow or blocked air intake with your furnace. This can cause several issues, from overheating to long heating cycles, and can cause your furnace to blow cold air through your home as well as result in higher energy bills due to those long heating cycles. Repairing this problem could be as simple as replacing your air filter or as complex as repairing your furnace intake system. If your intake system needs repair, it’s probably best to hire a professional HVAC company. Whatever your furnace repair needs are, we can help! If you are in need of furnace repair, reach out to Home Service Plus today.

Clogged Condensate Lines

State-of-the-art furnaces are designed with condensate drain lines to help eliminate moisture from your furnace. The reasons for these condensation lines have to do with the efficiency of your furnace. High-efficiency furnaces produce a lot of water that if not drained out, and can cause inefficient combustion by inhibiting the reactions that happen within your furnace. If they are clogged, the furnace may automatically deactivate your burners as a safety precaution, causing your furnace to blow cold air throughout your home! If your broken furnace is a model designed for efficient heating and has some of these condensate lines, reach out to Home Service Plus to have your furnace either repaired or inspected!

Damage to Your Ductwork

In homes with broken furnaces, the problem may not even be the furnace. Sometimes broken ductwork can result in your furnace blowing cold air. Many times, holes or gaps in your ductwork could be allowing cold air in from your attic or other areas of your home and/or allowing warm air out before it reaches the rooms you are hoping to distribute warm air to. These holes can be caused by age, quickly changing temperatures, or even pests that do damage to your property. Your furnace might be working fine, but the ductwork might be preventing warm air from getting where it needs to go! If you think this might be the case, reach out to Home Service Plus for furnace and HVAC repair in Winnipeg!

A Damaged Flame Detector

Your furnace is filled with different safety features to help your furnace run smoothly while protecting your home from potential malfunctions. One of these safety features is the flame detector which is designed to tell the furnace whether there is a flame present in the furnace or not. When used in tandem with other safety features, the flame detector is used to prevent harmful gas leaks and other potentially dangerous malfunctions. However, if it’s broken, your furnace may think that a flame is lit even when it’s not meaning that it will run without heat and could cause your furnace to blow cold air throughout your home. If this is the case and you are in need of furnace repair, reach out to Home Service Plus today!
