Oil heating costs Massachusetts homeowners $3,200+/year for a typical home. A cold-climate heat pump delivers the same warmth for roughly $1,100/year -- saving over $2,000 annually. With Mass Save and HEAR rebates covering up to $16,500, the payback period is shorter than ever.

Large Home 3,000 sq ft ~1200 gal oil/yr | ~$4,800 1200 gal x $3.80 | ~$1,650 9,200 kWh x $0.18 | $3,150 $263/month |
Massachusetts heating oil prices have been volatile for years, swinging between $2.50 and $5.00+ per gallon depending on global supply, refinery output, and winter severity. As of early 2026, the average price sits around $3.80/gallon. Unlike electricity rates, which are regulated and published in advance, oil prices can spike 20-40% in a single cold snap.
Oil prices fluctuate with global markets. A single geopolitical event can add $0.50-$1.00/gallon overnight, blowing up your heating budget with no warning.
Oil delivery companies and boiler service technicians are declining in number as the industry shrinks. Service calls and emergency repairs are getting more expensive and harder to schedule.
Aging oil tanks are an environmental and financial liability. A leaking underground tank can cost $10,000-$50,000+ to remediate, and homeowners insurance often excludes oil contamination.
The typical conversion takes 4-8 weeks from initial assessment to final inspection. Here is what happens at each stage.
A Mass Save energy advisor performs a no-cost home energy assessment. They evaluate insulation, air sealing, duct work, and current heating system to determine heat pump sizing needs.
Your installer performs Manual J load calculations to determine the correct number of indoor and outdoor units. Cold-climate heat pumps (rated to -15F) are specified for Massachusetts winters.
Building permits are pulled from your municipality. Mass Save and HEAR rebate applications are submitted. Your installer handles the paperwork.
Outdoor condenser units and indoor air handlers are installed. Refrigerant lines are run, electrical connections made, and the system is commissioned. Most installations take 1-3 days.
Mass Save schedules a post-installation inspection to verify equipment meets program requirements. Once approved, rebates are processed and your system is cleared for full operation.
When you switch from oil to a heat pump, you will eventually need to address your oil tank. Massachusetts DEP has specific requirements depending on whether your tank is above ground (AST) or underground (UST).
Pro tip: Get your oil tank inspected before listing your home for sale. A clean tank removal adds value, while a leaking UST can torpedo a deal. NuWatt can coordinate tank removal as part of your heat pump conversion project.
Massachusetts homeowners switching from oil can stack two major rebate programs. The federal 25C tax credit is no longer available, but these direct rebates remain strong.
HEAR rebate amounts depend on household income. Households at or below 80% of area median income qualify for 100% coverage up to $8,000. Households at 80-150% AMI qualify for 50% coverage. Above 150% AMI, HEAR is not available but Mass Save rebates still apply.
Most oil-to-heat-pump conversions in Massachusetts are completed within 4-8 weeks. The timeline depends on permit processing speed in your municipality, Mass Save assessment scheduling, and equipment availability.

Switching from oil to a heat pump is one of the single largest carbon reductions a Massachusetts homeowner can make.

Burning 800 gallons of heating oil produces approximately 8.5 tons of CO2 per year. A heat pump powered by the MA grid (which is ~40% renewable and growing) produces roughly 2.5-4.5 tons of CO2 for the same heat output. As the grid gets cleaner, your heat pump gets greener automatically.
For most Massachusetts homeowners, the answer is yes -- but the specifics matter. Here is an honest analysis of when it makes sense and when to think twice.
For most Massachusetts oil-heated homes, a heat pump conversion saves $1,500-$3,000+ per year in heating costs. With Mass Save rebates of up to $8,500 (available to all homeowners) and potential HEAR rebates of up to $8,000 (income-qualified), the net cost can be as low as $1,500-$8,000. At $2,000+/year in savings, the payback period is typically 2-5 years. After that, the savings are pure profit for the 15-20 year life of the system.
A whole-home cold-climate heat pump system for a typical Massachusetts home costs $15,000-$25,000 before rebates. After Mass Save ($8,500) and HEAR rebates (up to $8,000 for income-qualified households), out-of-pocket costs can drop to $5,000-$10,000. With annual savings of $2,000+, most systems pay for themselves in 3-5 years.
Yes. Modern cold-climate heat pumps (such as Mitsubishi Hyper-Heat and Fujitsu XLTH) operate efficiently down to -13F to -15F. They maintain over 75% of their rated capacity at 5F, which covers the vast majority of Massachusetts winter conditions. For the coldest nights, many homeowners keep their oil system as backup during the first year, then fully decommission it.
You are not legally required to remove your oil tank immediately, and many homeowners keep it as backup during the first winter. However, abandoned oil tanks can become environmental liabilities. Massachusetts DEP recommends proper decommissioning. Above-ground tank (AST) removal costs $500-$1,000, while underground tank (UST) removal runs $1,500-$3,000+ depending on soil testing requirements.
Mass Save offers up to $8,500 per home for heat pump installation (increased from $2,500 for oil-to-heat-pump conversions). Income-qualified households can also stack HEAR rebates of up to $8,000 from the federal program. The federal 25C tax credit expired on December 31, 2025 and is no longer available. Total rebates can reach $16,500 for qualifying households.
A typical 2,000 sq ft Massachusetts home using 800 gallons of oil per year (~$3,200/yr at $3.80/gallon) will spend approximately $1,100/yr on heat pump electricity using the heat pump electric rate ($0.18/kWh). That is annual savings of roughly $2,100. Savings are even higher for homes currently using more oil or with poor boiler efficiency.
Eversource and National Grid offer a discounted heat pump electric rate of approximately $0.18/kWh during the heating season (November through April), compared to the standard residential rate of ~$0.33/kWh. You must have a qualifying heat pump and apply through your utility to receive this rate. The rate applies to your entire household usage during those months.
Yes. Heat pumps provide both heating and cooling. A ducted or ductless heat pump system replaces both your oil furnace/boiler and your air conditioning. Many Massachusetts homeowners find that eliminating separate window AC units and a central AC system provides additional savings and improved comfort.
The full process from initial energy assessment to final Mass Save inspection typically takes 4-8 weeks. The actual installation is usually completed in 1-3 days. Permit timelines vary by municipality, and Mass Save inspection scheduling can add 1-2 weeks after installation.
Many homeowners keep their oil system as backup for the first winter season to build confidence in the heat pump. Cold-climate heat pumps rated to -15F handle Massachusetts winters well, and most homeowners find they rarely or never use the oil backup. After one full heating season, the oil system can be decommissioned and the tank removed.
No. The federal Section 25C energy efficiency tax credit expired on December 31, 2025, under the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025. There is no federal tax credit for residential heat pump purchases in 2026. However, Massachusetts state rebates through Mass Save and federal HEAR rebates (direct rebates, not tax credits) remain available.
