SERVICE & MAINTENANCE

You invested in a Generac automatic home backup generator, and now you’re never without power. But just like a car, air-cooled backup generators need to be properly maintained to perform as intended. All generators require periodic maintenance, such as oil and filter changes to ensure maximum performance for years of reliable service. Whitehart offers bi-annual service under our service contract, which covers checking over installed units and any required maintenance items such as filters, oil etc. Or call us to schedule a specific service. We currently service over 100 air-cooled and liquid-cooled generators in the Wimberley and surrounding areas.

If your unit is not connected to wifi, then it’s critical to get new firmware installed by a certified technician at least annually. We recommend network connectivity for all installed units and we’re able to install cellular antennae if your wifi network is simply too far from the generator or not on a stable connection.

If we find any problems with a generator that we are servicing, we are able to process warranty claims for new parts and labor as Generac certified service technicians for units that are still under warranty. That means no cost to you for parts, labor or travel. We have Generac certified air-cooled and liquid-cooled technicians – so we can service home and commercial systems. If your warranty has expired, we can counsel you on adding an extended warranty.

We carry Generac maintenance kits if you want to do the maintenance yourself.  Generac requires scheduled maintenance at 25 run hours for new air-cooled units and then every 100 run hours. However, they recommend that you have your unit checked every 6 months by an authorized service dealer. We highly recommend using factory parts and only the highest quality full synthetic oil.

Refer to your owner’s manual for routine maintenance procedures and schedules.

Here are some basic things that you should do to keep your Home Backup Generator running smoothly:

Verify Weekly:

• The LED indicator on the side of the generator is a solid green color. Amber or red lights require a service visit. No light at all means the generator is not on.
• Control panel read out is clear and operational. The unit should say “Ready to Run”!

Verify Monthly:

• Each side and the back of the generator are free from landscape materials (including eroded dirt, plants, fences and other materials).  The required generator clearance is 18” from the back, 36” from each side and 5’ from the top.
• All foreign material is removed from inside and outside the enclosure and the louvers on the sides and back of the generator. Here in the Texas hill country, mud-dabbers like to build nests inside the enclosure.
• The generator is not in the direct path of irrigation systems.  Also check the surrounding area to make sure the unit is not in standing water.
• Mounting surface is in good condition (free from cracks, stable, level, etc.).
• No oil/ residue on the inside base of the enclosure indicating a potential oil leak.
• Check the oil level using the dip-stick.  Add oil sparingly – remember these are typically 2.5 quart systems and do not need much oil.
• Verify that the battery is charged and reads a healthy voltage (in the range of 13 volts).

Ideally, your generator should be programmed to do a test run either weekly or every other week. We normally program ours to run on Monday mornings. This keeps the unit in top performance and ready to fire up in case of an outage. It also means that the unit will self-diagnose any issues during the test run instead of during an outage. If your unit shows an error code, write it down and call us to arrange a service call.
