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.

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.
