A few good questions.
What does a home energy audit include?
HeatMizer reviews your comfort concerns, energy use, insulation, and existing systems. Depending on your home, diagnostic work can include blower door testing, infrared imaging, and ventilation and combustion safety checks. The findings help you prioritize improvements.
Should I air seal before adding attic insulation?
Air sealing and insulation work together. Sealing gaps limits unwanted air movement, while insulation slows heat transfer. HeatMizer evaluates both when planning an attic insulation project, including ventilation needs.
How much does insulation or heat pump installation cost?
Pricing depends on your home, the work required, access, materials, and equipment. Contact HeatMizer for a project-specific quote and a review of applicable rebates. An energy audit can help establish which improvements to prioritize.
Do you clean existing heat pumps?
Yes. HeatMizer provides professional heat pump cleaning and maintenance, including filter care, coil cleaning, and performance checks. Call to discuss your system and service needs.
Which service should I start with?
If you’re unsure why your home is uncomfortable, an energy audit can help identify the cause. If you already know you need insulation or heat pump service, call us to discuss that project directly.
Do you offer both insulation and heat pumps?
Yes. HeatMizer provides insulation, air sealing, home energy audits, and heat pump installation, maintenance, and cleaning. We consider how these improvements work together.
Can you help with Efficiency Maine rebates?
Yes. Our team can help you review available incentives and the requirements for your project. Rebates are subject to current program rules and eligibility, so confirm the details before starting work.
Do you work on existing homes?
Yes. We work with existing homes, including older homes with insulation and air leakage challenges. We can discuss the right approach for your home’s construction and condition.
