What Should I Know About Owning a Furnace Unit?
Posted On: February 27, 2025
Owning a furnace comes with responsibilities to ensure efficiency, longevity, and safety. Here are the key things you should know:
1. Types of Furnaces
- Gas Furnaces – Common and energy-efficient, but require proper ventilation and regular inspections for gas leaks.
- Electric Furnaces – Safer and easier to maintain but may cost more in electricity.
- Oil Furnaces – Powerful but require more maintenance and are less common.
2. Maintenance is Key
- Change or clean air filters every 1-3 months to maintain airflow and efficiency.
- Schedule annual professional inspections to check for leaks, wear, and efficiency.
- Clean vents and ducts periodically to prevent dust buildup and improve air quality.
3. Energy Efficiency & Cost
- A furnace's AFUE rating (Annual Fuel Utilization Efficiency) indicates how efficiently it converts fuel to heat. The higher the rating, the better.
- Programmable thermostats help save on energy costs by adjusting the temperature when you're not home.
- Proper insulation in your home reduces furnace workload and energy bills.
4. Signs of Problems
- Unusual noises (banging, whistling, rattling) could indicate mechanical issues.
- Uneven heating may mean a problem with the ducts, thermostat, or furnace itself.
- Frequent cycling (turning on and off) suggests thermostat issues or restricted airflow.
- A yellow or flickering pilot light (for gas furnaces) could indicate a carbon monoxide risk.
5. Safety Considerations
- If you have a gas furnace, install carbon monoxide detectors to prevent poisoning risks.
- Keep the area around the furnace clear of flammable items.
- Know how to turn off your furnace in case of emergencies.
6. Lifespan & Replacement
- Furnaces typically last 15-20 years with proper maintenance.
- If repair costs become frequent or exceed half the cost of a new unit, consider replacing it.
- Upgrading to a high-efficiency model can lower heating costs over 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 !

Great experience getting an old furnace replaced.
Sales Guy (Dave) was great - honest, responsive, and friendly.
The work itself was done quickly and we are very happy with the outcome, thank you! We recommend TwinTech!

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.
