BOOK SERVICEAir Source Heat Pump FAQ for Massachusetts Residents
Basic Heat Pump Information
What is an air source heat pump?
An air source heat pump is a heating and cooling system that transfers heat between the indoor air and outdoor air. Unlike furnaces or boilers that generate heat by burning fuel, heat pumps move existing heat from one place to another, making them more energy efficient.
How do heat pumps work?
Heat pumps work like refrigerators or air conditioners but can operate in both directions. In heating mode, they extract heat from outdoor air (even cold air) and transfer it inside your home. In cooling mode, they remove heat from indoor air and release it outside.
Can heat pumps work in cold Massachusetts winters?
Yes! Modern air source heat pumps are designed to work efficiently even in cold climates. Today’s technology is vastly improved over older generations of heat pumps and can operate effectively in sub-zero temperatures. Many Massachusetts homes now use heat pumps as their sole heating system.
Do heat pumps provide air conditioning too?
Yes, air source heat pumps provide both heating and cooling. They function like air conditioners during summer months and are typically more efficient than traditional central air conditioners, window units, or through-wall air conditioners.

I WANT MY DEALBenefits and Considerations
How energy efficient are heat pumps compared to traditional heating systems?
Heat pumps are significantly more energy efficient than traditional heating systems like oil or gas boilers and furnaces because they move heat rather than generate it. Depending on your existing system and usage patterns, you could see substantial energy savings.
Will a heat pump reduce my carbon footprint?
Yes. Switching from gas or oil to an electric heat pump will decrease your carbon footprint. As Massachusetts continues to increase renewable energy sources like wind and solar in its electricity mix, your heating system’s environmental impact will continue to decrease over time.
How do heat pumps support Massachusetts’ climate goals?
Buildings account for 35% of Massachusetts’ carbon emissions. By electrifying heating systems and moving away from fossil fuels like natural gas and oil, heat pumps help the state meet its ambitious climate targets.
Even if you don’t see immediate savings on your energy bills (particularly if you’re switching from natural gas), you’re contributing to a cleaner grid and helping reduce overall carbon emissions. The MassSave® program now prioritizes these climate benefits as much as energy savings, which is why substantial rebates are available even when the economics might be neutral in the short term.
Are heat pumps low maintenance?
Yes. Air source heat pumps have fewer mechanical components than traditional heating systems like oil or steam boilers, making them simpler to maintain and service. Regular maintenance mainly consists of changing filters and keeping outdoor units clear of debris.
How important is insulation when installing a heat pump?
Very important. A well-insulated home will not require as large a heat pump system as a poorly insulated one. Before installing a heat pump, it’s recommended to evaluate your home’s insulation and make improvements if necessary. Through Paradigm Energy Services, McMahon offers no-cost energy assessments to help with this evaluation.
Cost and Incentives
How much does it cost to install a heat pump in Massachusetts?
Installation costs vary depending on your home’s size, existing ductwork, system type, and other factors. However, incentives and rebates can significantly reduce your upfront costs.
Check out McMahon’s current heat pump deals and special offers.
What incentives are available for Massachusetts residents?
MassSave incentives include:
- Rebates up to $10,000 for whole-home air source heat pump systems
- 0% financing options through the Heat Loan Program
- Additional incentives for income-eligible households
McMahon can take delivery of the incentives on a turn-key basis so that you don’t need to wait for rebates.
How do I qualify for MassSave heat pump incentives?
Most Massachusetts residents qualify for MassSave incentives. The first step is typically to schedule a no-cost home energy assessment. The assessment will help determine which incentives you’re eligible for and recommend the appropriate heat pump solution for your home.
Will I save money in the long run with a heat pump?
In most cases, yes. While the initial installation cost may be higher than replacing a traditional heating system, the energy savings over time, combined with available incentives, often make heat pumps an economical choice. Your exact savings will depend on your current heating fuel, electricity rates, and home efficiency.
Types of Air Source Heat Pumps
What’s the difference between ducted and ductless air source heat pumps?
Ducted heat pumps (also called central heat pumps) distribute heated or cooled air through existing ductwork, similar to traditional central air conditioning systems. They’re ideal for homes that already have ductwork and for homeowners who want to maintain a uniform temperature throughout the house.
Ductless heat pumps (also called mini-splits) deliver air directly into rooms through wall-mounted or ceiling-mounted indoor units. They don’t require existing ductwork, making them perfect for homes without ducts, room additions, or for providing supplemental heating and cooling to specific areas.
What is a mini-split system?
A mini-split is a type of ductless air source heat pump system consisting of an outdoor unit connected to one or more indoor units via refrigerant lines. The term “mini-split” refers to the fact that the system “splits” the heating/cooling function between the outdoor compressor unit and the indoor air-handling units. Mini-splits offer zone control, allowing you to heat or cool specific rooms independently.
Which type of heat pump is better for my home – ducted or ductless?
The best choice depends on your home’s characteristics:
Choose ducted if:
- Your home already has ductwork in good condition
- You prefer a single thermostat controlling the whole house
- You want a more traditional HVAC appearance
Choose ductless (mini-splits) if:
- Your home lacks existing ductwork
- You want zone control to heat/cool specific rooms
- You’re adding onto your home or converting spaces
- You have rooms that are consistently too hot or too cold
- You want to avoid the energy losses associated with ductwork
The best and safest way to make a choice is to have one of our professionals visit your home and discuss your situation.
Can I get rebates for both ducted and ductless heat pumps in Massachusetts?
Yes! MassSave offers rebates for both ducted and ductless air source heat pump systems. The rebate amounts may vary depending on the type and efficiency of the system. A no-cost home energy assessment can help determine which system type and rebate levels you qualify for.
Installation and Operation
Do I need to completely replace my existing heating system?
Not necessarily. Many Massachusetts homeowners opt for “hybrid” systems where the heat pump handles most heating needs, but the existing system remains in. Your energy assessment can help determine the best approach for your specific situation.
Will my heat pump work during power outages?
No, heat pumps require electricity to operate. If power outages are common in your area, you might consider a backup generator or a secondary heating system.
How loud are heat pump systems?
Modern heat pumps operate quietly. Indoor components typically produce sound levels similar to a refrigerator, while outdoor units are comparable to central air conditioners. Proper installation can further minimize noise concerns.
How long do heat pumps last?
With proper maintenance, air source heat pumps typically last 15-20 years. This is comparable to traditional heating and cooling systems.
