Is My Furnace Having Issues?
Posted On: March 4, 2025
If you're wondering whether your furnace is having issues, here are some common signs to look for:
1. Unusual Noises
- Banging, clanking, or squealing sounds may indicate a mechanical issue.
- Rattling or vibrating can signal loose parts.
2. Weak or No Heat
- If your furnace is blowing cold air, the thermostat, pilot light, or gas supply could be the issue.
- Uneven heating or weak airflow might indicate a clogged filter or failing blower motor.
3. Frequent Cycling
- If the furnace turns on and off too often, it may be due to a dirty filter, thermostat issues, or improper sizing.
4. Strange Smells
- A burning smell could indicate dust buildup or an electrical problem.
- A rotten egg smell could signal a gas leak—evacuate immediately and call a professional.
5. Increased Energy Bills
- A sudden spike in energy costs could mean your furnace is running inefficiently.
6. Yellow or Flickering Pilot Light
- A blue flame is normal. A yellow or flickering flame may indicate carbon monoxide or gas supply problems.
7. Poor Air Quality
- If you notice excessive dust, dryness, or respiratory issues, your furnace filter or ventilation system may be the cause.
If you're experiencing any of these problems, it may be time for maintenance or professional inspection.

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 !
