What Parts of My Furnace Can be Replaced?
Posted On: October 5, 2024
When it comes to furnace maintenance or repair, several parts can be replaced to keep the system running efficiently. Here’s a breakdown of the most commonly replaced parts in a furnace:
1. Air Filters
- Function: Filters remove dust, debris, and allergens from the air before it circulates through your home.
- Replacement Frequency: Regularly, depending on usage (typically every 1-3 months).
2. Blower Motor
- Function: Powers the fan that distributes warm air throughout your home.
- Replacement Signs: If the motor makes loud noises or fails to blow air effectively.
3. Heat Exchanger
- Function: Transfers heat from combustion gases to the air that flows through your ducts.
- Replacement Signs: If it cracks or corrodes, leading to potential carbon monoxide leaks—a serious safety issue.
4. Thermostat
- Function: Controls the temperature of your furnace and your home.
- Replacement Signs: When your furnace has trouble reaching the set temperature, or if the thermostat malfunctions.
5. Ignitor or Pilot Light
- Function: Lights the burner to produce heat.
- Replacement Signs: If the furnace fails to ignite, or you notice inconsistent heating.
6. Flame Sensor
- Function: Detects the burner flame and shuts off the gas if no flame is present to prevent gas leaks.
- Replacement Signs: When your furnace repeatedly shuts off due to faulty flame detection.
7. Burner
- Function: Combusts gas to produce heat.
- Replacement Signs: If rust or dirt buildup impacts the burner’s ability to function properly.
8. Limit Switch
- Function: A safety device that shuts off the furnace if it overheats.
- Replacement Signs: When the furnace shuts off prematurely or fails to turn on.
9. Thermocouple
- Function: Monitors the pilot light and controls the gas valve.
- Replacement Signs: If the pilot light keeps going out, indicating the thermocouple may be faulty.
10. Control Board
- Function: Coordinates the furnace’s operations, including the blower, ignition, and gas valve.
- Replacement Signs: If multiple components stop working in sync or the furnace malfunctions frequently.
Replacing these parts helps extend the life of your furnace and maintain its energy efficiency. Always consult a professional for proper diagnosis and replacement of parts.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
