Benefits of High Efficiency Gas Furnaces for Millis Residents
Upgrading to a modern high efficiency gas furnace pays off in multiple ways. From comfort and savings to eco-friendly operation, Millis homeowners have much to gain.
Lower Annual Heating Costs
Older furnaces can have AFUE ratings as low as 60–70%, meaning nearly half of the fuel is wasted. In contrast, new high efficiency gas furnaces offer:
- AFUE ratings of 90–98%, maximizing fuel use
- Reduced greenhouse gas emissions
- Noticeably lower monthly gas bills
For a typical 2,000 sq. ft. Millis home, that could mean saving hundreds each winter.
Improved Indoor Air Quality and Comfort
Replacing an aging system goes beyond savings. It also provides better airflow and cleaner operation.
- Sealed combustion units prevent backdrafts from entering your home
- Variable-speed blowers maintain consistent temperature
- Optional HEPA filters enhance allergen control
In neighborhoods near wooded areas like Bogastow Brook, enhanced filtration helps reduce pollen and mold intrusion inside the home.
Quieter and Smarter Operation
Modern furnaces offer more than just warm air—they’re also intelligent and unobtrusive.
- Quiet operation ideal for smaller homes and in-law apartments
- Smart thermostats allow for mobile temperature control
- Zoned systems adjust heat by room or floor level
“Residents in Millis switching from 20-year-old systems to modern dual-stage gas furnaces are often amazed by the dramatic drop in sound and energy usage.”

Understanding AFUE Ratings and Efficiency
If you’re shopping for a new furnace, you’ll see AFUE ratings listed prominently. But what does that really mean?
What Is an AFUE Rating?
AFUE stands for Annual Fuel Utilization Efficiency. It tells you what percentage of fuel gets converted into usable heat.
- Old units: 60–75% AFUE
- Mid-efficiency (often discontinued by code): 80–89%
- High efficiency gas furnaces: 90–98% AFUE
Why High AFUE Is a Must in a Cold Climate
In Millis, where your furnace may run for over 4,000 hours per season, creating heat efficiently preserves your gas supply and budget.
- 95% AFUE units convert nearly all fuel into heat
- Less exhaust and fewer emissions with sealed combustion
- Saves around $300–$500 annually compared to older models
Other Efficiency Factors to Consider
- Two-stage burners for smoother operation
- Variable-speed fans for flexibility and reduced cycling
- Insulated cabinets to reduce radiant heat loss
