"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

FAQs for attic insulation installation projects in Nashua, NH

The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.

You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.

Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.

Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
