Anyone building a new residential home in America. Also, depending on state homeowners may need this for renovation work being done to home.
Yes. In Massachusetts, we assist builders and homeowners in navigating and applying for Mass Save® rebates and no-cost upgrades. We also support rebate access in Maine, New Hampshire, Michigan, and Ohio, where available.
Typically, we require about 2 days lead time to schedule an audit and complete the necessary tests (blower door, duct blaster) depending on the home’s size and complexity. You’ll receive all required documentation for code compliance and any applicable rebate submissions. On site inspections typically take one to two hours depending on the size of the home.
Both. We support builders, contractors, and developers and work directly with homeowners for insulation inspections, rebate documentation, and system efficiency testing.
Our energy audits are tailored for new home construction and renovations. We inspect your insulation, HVAC efficiency, air sealing, and ductwork design to ensure your home is energy code compliant and built for long-term comfort and savings. If needed, JB’s Home Energy can do thermal imaging on a home to see where air leaks are coming from.
Manual J (load calculation), Manual D (duct design), and Manual S (equipment sizing) are required for building code compliance. They ensure HVAC systems are properly sized and designed for maximum efficiency and comfort. JB’s Home Energy specializes in providing these reports for new construction projects.
A blower door test measures how airtight a home is. It’s required in most states for new construction code compliance and helps identify leaks in hopes to reduce drafts, moisture issues, and energy loss. We provide these tests as part of our audit and inspection package. This test typically occurs at the very end of construction.
Our insulation inspections are done before putting up a drywall to identify missing or poorly installed insulation. This ensures your home passes inspection and performs efficiently for decades. It’s also often required to qualify for rebates or meet stretch code standards.
Duct-EZ® is a high-performance spray-on duct sealant that reduces air leaks in duct systems. It improves airflow, energy efficiency, and system performance- this vital for builders to ensure code compliance while testing a duct system. Our team applies our Duct EZ material to the HVAC system in any areas it could possibly leak.
We seal gaps, cracks, and joints in your home’s structure using advanced materials. This improves indoor air quality, reduces energy costs, and helps meet blower door test thresholds for code compliance.
- Energy calculations: Builder has prints ready to get a new home started and needs to get the documents for his permit. He sends us the blueprints for the home with a “builder information sheet” telling me what he is going to be putting into the home as far as insulation, windows, doors, HVAC is concerned. We then model out the home and make sure that it is meeting code requirements. Once that is complete we give him the paperwork needed to get his permit.
- Thermal Bypass Inspection (Insulation inspection): Once the home is insulated we come in and make sure that everything that was modeled in the home was actually installed. We document insulation, window, HVAC, specs and ensure that the home will pass the blower door and duct leakage test once drywall is put up.
- Blower Door & Duct Leakage Test: A blower door and duct blaster test is required on every new home in the state in order to get an occupancy permit. The best time to do a blower door test is once the carpet in the home has been laid and the thermal envelope is sealed. This test ensures that the air leakage in the home and duct system is at an acceptable level for code requirements.

We assess insulation, air sealing, HVAC sizing, ventilation, and perform blower door testing to evaluate your property’s or building’s energy performance.
Yes. Many programs require an audit to determine eligibility and verify that improvements were made.
Audits typically take 1–3 hours depending on the size and complexity of the property.
Yes. Energy-efficient properties and buildings often have higher value and faster sales. An energy audit can help document that efficiency.
Absolutely. We offer both residential and commercial energy audits to builders and contractors to meet building code and performance standards.
Air sealing, duct sealing, insulation, HVAC upgrades, and energy modeling are among the top qualifying services.
We provide all required documentation (including test results and modeling reports) to help you submit and get approved quickly.
No. Many programs also offer rebates for energy-efficient retrofits and home upgrades.
Rebates vary, but typical savings range from $200 to over $2,000 depending on the project and services used.
Start with a home energy audit or code-required testing! We’ll guide you from there.
Before drywall or interior sheathing is installed—usually right after insulation is placed.
They’re often required for rebate programs and are highly recommended to pass blower door testing.
We look for insulation gaps, compression, misalignment, missing coverage, and improper contact with air barriers.
Yes—correct insulation installation is a key requirement for qualifying the Mass Save® Program rebates and incentives.
Most take 30–90 minutes depending on project size and access.
Before drywall installation and ideally before final blower door testing. It’s also effective in existing homes with comfort or draft issues.

I reached out to JB’s Home Energy because they were partnered with MASS Save, and it was honestly one of the biggest mistakes I’ve made. The owner, Josh, had terrible communication throughout the entire process. I was constantly left in the dark and had to follow up multiple times just to get basic updates or information. The experience was frustrating and unprofessional from start to finish. I strongly recommend looking elsewhere for any MASS Save programs and avoiding this company if possible. If you enjoy being left in the dark and dealing with poor communication, then this is the perfect company for you. Otherwise, save yourself the headache and go elsewhere.Posted onTrustindex verifies that the original source of the review is Google.
