Why is My Furnace Not Heating Properly?
Posted On: October 29, 2023
However, here are some common reasons why a furnace may not be heating properly:
-
Thermostat Settings:
- Check if the thermostat is set to the desired temperature.
- Ensure that the thermostat is set to the "Heat" mode.
-
Clogged or Dirty Filters:
- A dirty or clogged air filter can restrict airflow, reducing the efficiency of the furnace. Replace or clean the air filter regularly, typically every 1-3 months.
-
Pilot Light/Ignition Issues:
- If your furnace has a pilot light, ensure it is lit. For newer models with electronic ignition, check for error codes or ignition issues.
-
Gas Supply Issues:
- Verify that the gas supply to the furnace is turned on. If you suspect a gas supply issue, contact a professional immediately for assistance.
-
Thermocouple Problems:
- A faulty thermocouple may cause the gas supply to the furnace to be shut off. This is a safety feature to prevent gas leaks. A technician can check and replace a faulty thermocouple.
-
Burner Issues:
- Dirty or malfunctioning burners can affect the heating efficiency. If the burners are not lighting or staying lit, it may require cleaning or adjustment.
-
Blower Motor Problems:
- If the blower motor is not working correctly, it can result in inadequate heat distribution. Check for unusual noises or lack of airflow.
-
Ductwork Issues:
- Leaks or blockages in the ductwork can reduce the efficiency of your furnace. Inspect the ducts for any visible issues.
-
Dirty or Blocked Vents:
- Ensure that all vents and registers are open and not blocked by furniture or other obstacles. Clean any dust or debris around the vents.
-
Electrical Issues:
- Check for tripped circuit breakers or blown fuses in the electrical panel that powers the furnace.
If you have checked these common issues and your furnace still isn't functioning properly, it's recommended to contact a licensed HVAC professional to diagnose and address the problem. Working with gas appliances and furnaces can be dangerous, so it's crucial to prioritize safety and seek professional assistance when needed.

Dave was great in helping me get the proper units for my property, as well as getting them installed. The installers arrived when they said they would, and completed the project on time, and professionally. If I needed another furnace, I would use Dave again.

I have known Greg and Grant Dainty for many years and have used their company for my house and business. I recommended them also for my parents and sister and they all have been very satisfied with the quality of work for a reasonable price. I just recently had them install a new HVAC system in an older house and was very pleased with their work. Craig in Pickering. After meeting with various heating and air conditioning contractors I was referred to Twin Tech Heating and Cooling through a family member. Greg and Grant arrived at my home and provided me with an estimate and a plan as to how they were going to remove and replace my furnace and air conditioner. On the day of install Greg and Grant arrived at my home on time and were very professional and extremely courteous as to any questions or concerns that I had. The removal and install was truly professional and the attention to detail was exactly what I was looking for. Ive seen many installs from other contractors and I couldnt be any happier to have had such a clean looking install. The sheet metal work, ducting and venting all look fantastic. Upon completion Greg and Grant left me feeling extremely happy and very fortunate of a job well done. Thanks again Twin Tech!!

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment
