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.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.
