PM Tech's Residential Maintenance Plan Options

Our air-cooled residential generator maintenance plans are built around clearly defined service line items, making it easier to choose the level of protection that fits your generator and your household. Each plan is designed to support long-term reliability while giving homeowners different levels of maintenance coverage and added benefits.

What Each Maintenance Line Item Includes

Each plan is built from a combination of service line items. Understanding what each one includes can help you choose the right level of generator maintenance for your home and backup power needs. The uploaded PM Tech brochure defines these line items as Annual Preventive Maintenance, Semi-annual Secondary Maintenance, battery replacement if tested bad, one free service call, remote monitoring, and a 10% parts discount on upper-tier plans. 

Annual Preventive Maintenance (PM)

This is the foundation of every maintenance plan. Annual Preventive Maintenance is a comprehensive service visit designed to keep your residential generator operating reliably and to identify potential problems before they become larger repairs.

• Oil and filter changes
• Fuel system checks
• Battery system testing
• Valve adjustment, if needed
• Transfer test
• Control panel verification
• Overall system inspection

Semi-annual Secondary Maintenance (SM)

This intermediate maintenance visit is completed every six months to monitor system condition between full annual maintenance visits.

• Visual inspection
• Operational testing
• Minor adjustments
• Pre-PM assessment

Free Battery Replacement*

Plans that include battery replacement provide additional peace of mind. If the battery tests bad at the time of maintenance or service, it will be replaced according to the terms of the plan.

Free Service Call**

Select plans include one free service call per calendar year. This covers the first two hours of the on-site visit and helps reduce the cost of unexpected service needs. Parts are excluded.

Remote Monitoring***

The top-tier plan includes remote monitoring for added visibility into generator performance and quicker awareness of potential issues.

10% Parts Discount

Options Four through Six include a 10% discount on parts, adding extra value for homeowners who want more complete maintenance protection. The brochure lists this as 10%, which aligns with the designed maintenance program pages. 

What to Expect During a Generator Maintenance Visit

With any PM Technologies preventative maintenance plan, you can expect a thorough inspection of the major generator systems during your scheduled visit. Our technicians look for signs of wear, verify operation, and address minor issues when possible as part of the maintenance process. If larger repairs are needed, we will explain the issue clearly and provide recommendations for the next step.

Routine residential generator service helps support reliable performance during storms, utility outages, and severe seasonal weather across Michigan and Ohio. A well-maintained standby generator is more likely to start properly, transfer power correctly, and perform the way it should when your home needs it most.

To ensure the highest level of performance, we follow specialized maintenance procedures for both liquid-cooled and air-cooled generators based on manufacturer recommendations and industry best practices. The current page already includes links to both maintenance documents, and I’ve preserved that here.

Why Residential Generator Maintenance Matters

Your generator is not something you want to think about only after the power goes out. Preventative maintenance helps extend equipment life, improve reliability, reduce the risk of battery or fuel-related failures, and catch issues early before they become more costly. For homeowners in Detroit, Ann Arbor, Grand Rapids, Toledo, Dayton, Columbus, and surrounding areas, that kind of protection matters during summer storms, winter weather, and other unexpected outages.

PM Technologies has been serving residential and commercial generator customers since 1997, with a service-first approach built around long-term reliability and responsive support. We do not just install generators—we help homeowners maintain them properly so they are ready when it counts.
