The Importance of Performing Maintenance on Your Standby Generator

If you’ve had a standby generator installed at your home or place of business, you’ve already taken the first really important step to ensure your power stays on in the aftermath of a storm or natural disaster. Are you maintaining your generator properly to ensure it functions at its best when you need it most?

It’s possible that your investment will last decades—20 or 30 years—if well maintained (after all, it’s not working all the time and top-quality generators are built to run for tens of thousands of hours over their lifetime). To protect that investment and your home, preventive maintenance is necessary and should be done by a certified technician. If you are in a severe environment or have experienced numerous power outages, more frequent service may be needed.

As we shared in a video earlier this year, you as the owner, can perform a visual inspection every month or have your contractor do so, especially if the generator has been running for any extended period of time. You’ll first want to make sure the area is clean of debris and that no critters have set up house inside an enclosed unit. When the unit is not running, check the oil level and maintain the level as close to full as possible. Do not overfill it.

NOTE: if the generator has been running, wait 10 minutes after it shuts down so all of the oil in the engine can drain back into the sump.

What the generator technician will check semi-annually or annually

Make sure the company you call for maintenance follows this general systems and parts inspection list, which are key to your generator’s performance:

  • Air system (combustion and cooling air) – air filters should be replaced.
  • Starters (batteries and charger)
  • Transfer switch

These last two items are often overlooked so be sure your HVAC/generator contractor is checking these, as they help power the unit.

Other routine maintenance services are to replace, clean and/or perform a visual inspection of the following:

  • Oil & oil filter
  • Spark plugs & spark wires
  • Battery terminals & cables
  • Air intake & exhaust system
  • Engine starting system
  • Fuel lines & hoses
  • Voltage input & electrical connections
  • Vibration & insulation conditions
  • Control board operation
  • Transfer switch operation & controls

This is not a complete list of standby generator maintenance points, and there may be other preventive maintenance actions required for your particular unit; your installer or your new maintenance contractor should review these with you. Of course, having a preventive maintenance contract will ensure the inspections are done right, done on time, and that proper actions are taken without out having to think about them.

Don’t Get Caught Unprepared this Summer: The Importance of Semi-Annual Maintenance on Your HVAC system

With summer coming, there’s still time to make sure your central air conditioning system is ready for the heat and the pressures of the season. There are important routine maintenance tasks your HVAC professional should perform at this time of year (with others equally as important in the fall to prepare for winter).

Semi-annual system maintenance protects your system (and investment) from breakdowns which could end up costing far more to repair if problems go unnoticed. After all, it’s cost effective to fix a minor problem before it gets out of hand (and expensive to correct). Routine maintenance also ensures that your central air will run as efficiently as possible—and more reliably during peak times. Just as you wouldn’t let your car run for many thousands of miles without an oil change or engine check, the same goes for your HVAC unit.

When your air conditioning contractor shows up, ask if the following tasks are on the punch list.

  • Check the refrigerant charge – Refrigerant cools the air in your home; depending on which make and model of central air conditioning unit you have will inform how much refrigerant you need. Make sure the technician checks the refrigerant lines for any necessary repairs. Note that in the U.S., HVAC service contractors must have an EPA refrigerant usage certification in order to buy refrigerant and to repair systems that contain ozone-depleting refrigerants (CFCs) which are typically used in older air conditioning systems. Your technician must know which type to use on your unit.
  • Change the air filters – Air filters grab the billions of particles floating through your home as the air circulates, thereby delivering better air quality and protecting the system. We recommend high-efficiency pleated air filters, which have an electrostatic charge that attracts the tiniest particles, including pet dander and bacteria spores. These must be changed a few times a year to ensure your circulated air is as clean as possible, to reduce system wear and tear, and to lower energy costs by reducing the power needed to do the job.
  • Blow out the drain system – It’s important to clear debris and make sure the condensate drain for the air conditioner is not clogged. A clear drain avoids wasting energy and putting undue load on the unit (which will send out less cool air if the drain is obstructed). A properly maintained condensate drain enables the water to flow from a tray that captures it to a drain. Obstructions can cause water damage to the unit and in the winter, this can create high humidity levels promote the growth or mold or bacteria buildup.
  • Clean the condenser coil – Before any cleaning happens, the technician should remove the condenser covers or blankets outside (if you put them on in the winter) and ensure that the unit is intact after the winter. The suction line, which helps supply cool refrigerant back to the compressor in the outdoor unit, should be properly insulated (damaged insulation should be noted and addressed) to maintain optimal cooling. All debris (vegetation or trash) that has collected on and around the outdoor coil must be cleared in order to get the best possible performance from your system with good air flow. (Note: if you put mulch down around the compressor, don’t pack it too high here).
