HomeWorks can help you understand your options as you consider home improvements.
Through programs such as Electrify Cambridge and the Cambridge Energy Helpline, residents can also access local guidance and resources for exploring all-electric home upgrades and other ways to reduce household energy use.
Keeping Cambridge homes cozy can place significant demands on HVAC equipment through both winter and summer. Regular maintenance—often annually or seasonally, depending on the system—can help support consistent comfort and efficient performance throughout the year.
An HVAC system should be sized based on more than square footage alone. Your home’s layout, insulation, windows, air leakage, ductwork, and heating and cooling needs can all affect proper sizing. Equipment that’s too large or too small can contribute to comfort, efficiency, humidity, and performance problems.
Not every home requires an electrical upgrade to install a heat pump. The answer depends on your existing electrical service, available panel capacity, the equipment being installed, and other electrical loads in the home. These factors should be evaluated as part of planning the project.
Yes, a properly designed heat pump system can provide both heating and cooling. Whether a heat pump can meet all of your home’s needs depends on factors such as the home’s heating and cooling load, insulation, layout, existing ductwork, and system design. In some homes, heat pumps may also be used alongside existing equipment.
Yes. Ductless mini-splits can provide efficient heating and cooling without requiring traditional ductwork, making them a flexible option for homes and individual spaces where installing new ducts would be difficult.
Often, yes. Ductless mini-splits can provide heating and cooling without extending traditional ductwork, making them a potential option for finished attics and other converted spaces. The right solution depends on factors such as the space’s layout, insulation, electrical capacity, and heating and cooling needs.
Yes. Home electrification doesn’t necessarily have to happen all at once. Some homeowners replace equipment as it reaches the end of its useful life, while others prioritize specific upgrades based on comfort, efficiency, budget, and long-term goals. Planning ahead can help individual improvements work together over time.
A cold-climate heat pump can provide electric heating and cooling and may be an option for homes currently heated with gas. Before making the switch, it’s important to evaluate factors such as the home’s heating needs, insulation, electrical capacity, and the type of heat distribution currently in place.
Higher energy use can have several causes, including extreme weather, changes in thermostat settings, dirty filters, equipment problems, air leaks, inadequate insulation, or an HVAC system that’s losing efficiency. A professional evaluation can help narrow down what’s contributing to the increase.
Temperature differences between floors can result from airflow, ductwork, insulation, air leaks, sun exposure, HVAC system design, or the natural movement of warm air through the home. Identifying the factors involved can help determine whether the best solution is an HVAC adjustment, home-performance improvement, or combination of the two.
Not necessarily. Depending on your home and goals, a heat pump may be designed to provide most or all of your heating and cooling, or it may be used alongside existing equipment. The right approach depends on your home’s layout, current system, insulation, electrical capacity, and heating and cooling needs.
Your heating system can be working properly while air leaks around windows, doors, attics, and other areas allow cold outdoor air into the home. Air sealing and insulation can help reduce drafts while making it easier for your heating system to maintain a comfortable temperature.
Yes. Eligible Cambridge homeowners may qualify for Mass Save heat pump rebates when installing qualifying equipment. Rebate amounts and requirements depend on the type of system, existing heating equipment, project scope, and household eligibility. HomeWorks Energy can help you explore available rebates as you plan your upgrade.
Insulation and air sealing can reduce the amount of energy a home needs for heating and cooling, so they’re important factors to consider when planning a heat pump project. Understanding your home’s current weatherization can also help inform system design and future efficiency improvements.
Yes, heat pumps can be installed in many rental properties. The appropriate system depends on factors such as the building’s layout, existing heating equipment, electrical capacity, equipment placement, and how utilities are configured. Incentive programs may also have requirements specific to rental properties.
