From the Field
Honest, practical advice on heat pumps, insulation, and energy savings — from the crew that does the work.
The homeowners thought their biggest problem was the drafty living room. The energy audit told a different story, starting with the 4,200 CFM50 blower door result.
We booked 14 energy assessments last week in Greater Portland. By October, that number triples and the wait time doubles. Here is why spring gives you every advantage.
Maine heating oil hit $4+/gallon this winter. Spring is the best time to weatherize, add heat pumps, and lock in Efficiency Maine rebates before next...
Spring thaw exposes what winter hid. Ice dam scars, water stains in the attic, and compressed insulation are all signs your home was working too hard this winter. Here is what to look for and what to do about it.

Pre-1970's Maine homes were built with little or no insulation. They also benefit the most from weatherization because the gap between current and improved performance is enormous.
Portland's housing stock is old, and older homes lose heat in predictable ways. Here is where to start if you own a pre-1960's home in Greater Portland.
A 1960s Cape Cod in Portland was spending $3,800 a year on oil heat with cold bedrooms and ice dams. Weatherization plus two cold-climate heat pump heads changed everything. Here is how the project came together.
A Westbrook family cut annual heating costs from $3,500 to $1,400 by switching from oil to heat pumps.
Most people call us because their heating bills are too high. That is the reason they pick up the phone. But the improvements we make end up changing things they did not expect, and those changes are often the ones they talk about most.
A breakdown of where heat escapes in a typical Maine home, what each area costs you, and which fixes deliver the best return on investment.
If you want cooling this summer or heating savings next winter, the planning starts now. Here is the spring timeline for cold-climate heat pump installation in Maine, from assessment to rebate processing.
Before investing in solar panels, reduce your home’s energy waste with insulation and air sealing.
Efficiency Maine is adding $500 to heat pump rebates through the end of 2026. Here is what qualifies and how to capture it.
A 1950's Cape Cod in Portland was drafty, had ice dams, and cost $350/month to heat. See how insulation and air sealing cut heating bills by 40%.
Installing a heat pump without insulating first means a bigger, more expensive system. Learn why the order matters.
Gorham and Windham homes tend to be larger, oil-heated, and under-insulated. Here is how whole-home performance upgrades apply to these properties.
Maine has installed over 143,000 heat pumps, more per capita than almost any other state. Here are the real numbers behind adoption, cost savings, and what they mean for homeowners.
Scarborough homes built in the 1970s through 2000s still lose energy in predictable ways. Here is how to find and fix the gaps that drive up your bills.
We are headquartered in Westbrook at 865 Spring St. Here is what we know about weatherizing the mill-era homes and workers' cottages in our own backyard.
South Portland's post-war ranches and capes lose heat in predictable ways. Here is how insulation and cold-climate heat pumps work together to fix them.
Portland's older homes present unique insulation challenges. Learn what to look for in an insulation contractor and why cellulose works for New England housing stock.
Portland's older homes lose 25-40% of heated air through gaps in the building envelope. Learn how air sealing with blower door testing stops drafts at the source.
Portland homes need cold-climate heat pumps rated to -15F. Learn about sizing for triple-deckers, Victorians, and coastal homes plus Efficiency Maine rebates.
