## The honest read

Yestramski Electrical Services is an electrical contractor whose website describes residential and commercial generator services and maintenance in and around Contoocook, NH. Thomas G Yestramski holds New Hampshire electrician licence 8344, which is active on the state registry.

A 2026 customer said their generator failed to start on its weekly test over a weekend, and the owner, Dave, called back within 30 minutes and stayed on the phone walking through troubleshooting and a restart until everything was fixed. A 2024 customer who bought a home in New London said its generator had been installed and serviced by Yestramski since 2014; when a winter storm cut the power, the generator came on but the house had no power, and after a call back in about 10 minutes the owner walked them through troubleshooting steps until full power returned. A 2025 customer said the technician arrived early for their annual generator service.

A 2022 customer called Paul and his crew competent, personable and reliable, with very reasonable prices. A 2021 customer said they called to have work done and no one ever called back.

**Strengths:**
- Fast weekend callback — a 2026 customer said the owner called back within 30 minutes
- Storm troubleshooting — a 2024 customer regained full power after the owner's phone help
- Annual generator service — a 2025 customer said the technician arrived early

**Concerns:**
- A missed callback — a 2021 customer said no one ever called back
