Why Generator Maintenance Matters

A standby generator is a critical part of your home's comfort and protection. Without regular service, internal components can wear down, fluids can degrade, and batteries can fail, often without warning.

Professional maintenance helps identify potential issues early and ensures your system operates as designed during a power interruption.

Annual Generator Maintenance

Most generator manufacturers recommend annual maintenance to ensure proper operation and warranty compliance. CM Heating offers scheduled maintenance appointments to help homeowners stay ahead of required service and reduce the risk of unexpected failures. During a standard generator maintenance visit, our technicians focus on essential system checks and routine wear‑item replacement.

Steps in Generator Maintenance

Our generator maintenance service typically includes the following steps...

  • Replace air filter.
  • Replace oil filter.
  • Replace spark plugs.
  • Check battery voltage.
  • Run the generator in manual mode to confirm proper operation after maintenance.
  • Perform a final operational test.

These steps help ensure the generator starts correctly, runs smoothly, and responds properly when power is needed.

What to Expect During Service

Our maintenance process is designed to be thorough yet efficient. Technicians visually inspect accessible components, confirm normal operation, and test the generator under controlled conditions.

Maintenance services focus on existing components. Any repairs or part replacements outside of standard maintenance may be discussed separately if issues are identified.
