A well-maintained generator provides peace of mind when the power goes out. Routine maintenance, cleaning, batteries, readiness checks, and small service calls — done locally, priced clearly.
Our specialty
Residential standby generators — especially the small stuff
True Detective Home Services specializes in residential standby generators: routine maintenance, small service needs, readiness checks, battery issues, cleaning, and basic troubleshooting.
Already have a company that handles your annual maintenance? We can help with the smaller generator issues in between — batteries, readiness checks, cleaning, startup problems, monitoring/Wi-Fi issues, and basic troubleshooting. We document our work with photos and digital service records.
When texting for generator service, please include your name, town, generator make and model, a brief description of the issue, and photos if available.

Battery tests, replacement, terminal cleaning, and quick readiness checks so your unit starts when it matters.
Cleaning & detailing
Exterior and accessible interior cleaning, debris removal, and vent care — from a basic tidy-up to a deep clean.
Between-visit fixes
Startup issues, exercise-cycle troubleshooting, monitoring/Wi-Fi help, and basic diagnostics between annual maintenance visits.
