Gas to Heat Pump: Why More Waltham Homes Are Making the Switch

In Waltham’s shifting regulatory and climate-conscious environment, heat pumps provide a future-ready alternative to outdated fossil fuel systems. Here's why going from gas to a heat pump makes sense right now.

Energy Efficiency That Matches Massachusetts Winters

Heat pumps, especially air source heat pump systems, are far more efficient than traditional gas furnaces. Instead of generating heat by combustion, they transfer heat from the outside air—even in freezing conditions.

• Modern ducted heat pump models can operate efficiently in outdoor temperatures as low as -5°F
• They use significantly less electricity compared to the energy required to burn gas

Thanks to advances in cold-climate technologies, Waltham homeowners no longer have to choose between comfort and sustainability.

Energy Rebates and Local Incentives

Massachusetts is one of the most supportive states for heat pump adoption. Through the Mass Save program, Waltham homeowners can access generous rebates when switching away from gas heating systems:

• Up to $10,000 in incentives for qualifying full-system replacements
• No-cost home energy assessments to identify savings opportunities

These savings significantly reduce upfront costs, making switching from gas far more accessible.

Cleaner, Healthier Heating for Your Family

Gas combustion produces carbon monoxide and other pollutants. By contrast, heat pumps operate without burning fuels:

• Improves indoor air quality
• Reduces CO2 emissions from your home
• Aligns with Waltham’s climate action goals

Waltham is part of a growing number of communities committed to reducing reliance on fossil fuels—and converting gas to a heat pump is a meaningful step in that direction.

“Homes in Waltham heated by fossil fuels emit over twice the greenhouse gases of homes using high-efficiency heat pumps—switching is one of the single most impactful home upgrades you can make,” according to Massachusetts Clean Energy Center.

Replace Gas Furnace with Heat Pump: What Homeowners Need to Know

Replacing your gas furnace with a heat pump requires careful planning, especially in a climate like Waltham’s. Understanding the process can help make the transition seamless and cost-effective.

Determining If Your Home Is Heat Pump Ready

Before replacing your gas furnace, it’s essential to assess your home’s current infrastructure:

• Do you currently have ductwork? If yes, a ducted heat pump is likely a great fit.
• Do you want to retain gas heating as backup? A hybrid system may be the right solution.
• Are there rooms that are always too hot or cold? Zoned air source heat pump systems can solve that.

SumZero Energy Systems offers professional evaluations to determine the best system type based on your setup and the specific layout of your Waltham home.

Choosing the Right System for Waltham’s Climate Zones

Waltham’s chilly winters and humid summers make choosing a cold-climate air source heat pump crucial. Systems designed to perform in sub-zero temperatures carry ENERGY STAR ratings and qualify for state rebates.

Homeowners have the option of:

• Full electrification (complete gas to heat pump replacement)
• Hybrid systems that retain a gas furnace for backup in extreme cold, offering the best of both worlds

Professional Installation Makes a Big Difference

Waltham homes, many of which were built in the mid-20th century, often vary in insulation and design. Ensuring proper sizing and ductwork compatibility is critical to maximizing efficiency and comfort.

Choosing experienced professionals, like SumZero Energy Systems, ensures:

• Load calculations based on your home's insulation, window quality, and orientation
