Frequently asked questions

  • What is a Home Energy Audit and Assessment
    A home energy audit is a comprehensive assessment where our certified experts examine your home as a complete system to identify energy waste and efficiency opportunities. Using advanced diagnostic tools like blower door testing and thermal imaging cameras, we can pinpoint exactly where you're losing energy and money through air leaks, insufficient insulation, or inefficient systems. The audit provides you with a clear blueprint for improving your home's efficiency and comfort while reducing energy bills. You'll receive specific recommendations prioritized by impact and cost-effectiveness, and we'll help you qualify for valuable Efficiency Maine rebates to make these improvements more affordable. As both auditors and contractors, we can not only identify problems but also implement the solutions, ensuring you get the most value from your energy audit.
  • Is Spray Foam Insulation Fire Retardant?
    Yes, our closed-cell spray foam insulation includes fire-retardant properties. It's designed to meet building codes and safety standards while providing superior insulation performance.
  • What is R-value and why is it important?
    R-value measures insulation's resistance to heat flow - the higher the R-value, the better the insulation. Our cellulose offers R-3.5 per inch compared to standard fiberglass at R-2.2 per inch, providing better energy efficiency for your home.
  • What type of insulation should I use in my attic?
    We recommend either blown-in cellulose or spray foam depending on your specific needs. We'll assess your attic's condition, ventilation, and structure to recommend the most effective solution for your home.
  • Do I need to insulate my basement walls?
    Yes, basement insulation is crucial for energy efficiency. The current building code requires you to insulate your basement walls and use a vapor barrier. We'll assess your basement and recommend the most effective solution.
  • How much insulation do I need in the attic?
    The current building code of Maine requires you to have 49 R to 60 R in your attic. A thorough home energy audit would determine the optimal insulation levels for your specific situation.
  • How much insulation do I need?
    If it’s a new construction you should follow the state building code. If it’s an existing building you should maximize your insulation based on your cavity size and the insulation type.
  • Can I install insulation myself, or should I hire a professional?
    While some insulation projects can be DIY, professional installation ensures proper air sealing, correct installation techniques, and maximum efficiency backed by an energy audit. The field of energy auditing exists to repair the wrong insulation installed by non professionals. We bring 31+ years of experience and proper safety equipment to ensure the job is done right.
  • What are the benefits of spray foam insulation?
    Spray foam provides superior air sealing, moisture control, and insulation value with 7.2 R. It offers up to 50% energy savings, creates an air-tight seal, prevents moisture problems, and has an indefinite lifespan.
  • How often should insulation be replaced?
    Quality insulation like our spray foam has an indefinite lifespan. However, older insulation materials may need replacement if they're compressed, water-damaged, or showing signs of pest infestation. Wet insulation is like wet oven mitts which have no R value and need to be replaced. We can assess your existing insulation during an energy audit.
  • Is it worth insulating old homes?
    Absolutely! Older homes often have the most to gain from proper insulation as they usually have no insulation. Older homes require a different approach to insulation than modern homes. Improper insulation can lead to moisture problems and damage. That's why it's crucial to work with experienced professionals like Heatmizer. Our team understands the intricacies of older construction and will ensure your home is insulated safely and effectively, maximizing energy efficiency without compromising its structure.
  • What are the environmental impacts of different insulation materials?
    We prioritize eco-friendly options. Our cellulose insulation is made from recycled materials, and our spray foam helps reduce energy consumption. Both options help create a more sustainable, 'green' household.
  • How can I tell if my home is properly insulated?
    Signs of poor insulation include high energy bills, uneven temperatures between rooms, cold walls or floors, and drafts. We offer professional energy audits to accurately assess your home's insulation needs.
  • What is the best type of insulation?
    The best insulation depends on your specific needs, area being insulated, and budget. Cellulose insulation, made from recycled paper, offers superior air sealing, better sound dampening, and natural resistance to pests, fire, and mold compared to fiberglass.
  • What is air leakage?
    Did you know that the average home loses about 300 cubic feet of air every hour? That's like 1,200 basketballs escaping! And, of course, that same amount of outside air has to come in, impacting your comfort and energy costs in a negative way. This leakage can happen through gaps around windows and doors, unsealed electrical cables, chimneys, cracks in the foundation, and even through your attic.
  • What documentation is needed?
    The Heatmizer team handles all documentation requirements. We'll collect necessary information during our initial assessment and manage the paperwork process for you.
  • How do I qualify for rebates?
    If you're a year-round Maine resident, you automatically qualify for a 40% rebate on eligible upgrades through Efficiency Maine. Depending on your income and household size, this rebate could be as high as 80%. HeatMizer can help you navigate the rebate process. Contact us for a free consultation to learn more.
  • How long does approval take?
    Typically, Efficiency Maine processes rebate approvals within 2-3 days and submission of all required documentation. Our team monitors the process and keeps you updated.
  • When do I receive the rebate?
    Once approved by Efficiency Maine, rebate checks are typically issued within 2-3 weeks. We'll help track your rebate status throughout the process.
  • Can I combine different rebates?
    Yes, many Efficiency Maine rebates can be combined. Let's say you’re qualified for a 40% rebate on the insulation side that will automatically make you qualify for the heat pump upgrade too.
