Tips For Standby Generator Maintenance

The following are several tips on how you can maintain your standby generator:

Consider The Environment

Maintaining your standby generator means doing several tasks which vary in frequency and difficulty. Before doing any of the tasks, you should first consider some factors that can impact the state of your generator. First is the environment where the unit is to be installed. Since it is outside where it is exposed to the elements, is it sufficiently protected from rain, sun, and debris? Is the climate in your area cold, wet, and windy, or hot, dry, and dusty? Maintenance becomes more crucial the harsher the environment you live in.

Assess The Whole-House Generator Workload

You must consider the number of times you needed to use the generator in the previous year and how long the power outages lasted. Some regions do not experience power disruptions as much, while recurring issues in other places mean they expect power outages to happen at specific times of the year. These disruptions can last for several minutes or continue for several days. It all depends on what caused the outage. A generator that runs often will wear out its parts quicker, so it needs more attention than a unit that isn’t used as much.

Factor The Weather

The weather will significantly affect the generator. Some places are more likely to experience storms, and the strong winds can topple structures like telephone poles. Trees can also fall and may bring down electrical wires close to their perimeter. Be mindful of the months when these may happen. Book professional maintenance beforehand so you can go through the storm season without problems. Homeowners living in places with unpredictable winters should also prepare the same. Finish crucial maintenance tasks at least a month before the harsh weather arrives.

Call To Schedule An Appointment

Check the History of the Generator

If the house you recently bought has a standby generator, it is best to know the unit’s history, so talk to the previous owner if possible. You should ask them for important details about the unit, like its age and state. Inquire about its maintenance and ask for papers signed by the technician who worked on it. Find out the date the unit was last professionally inspected. You are fortunate if the system received regular maintenance and is completely operational. Otherwise, call your local expert to come and check it.


Ask for Help Regarding Advanced Power Generator Maintenance

Homeowners can conduct most maintenance tasks, but some are still best left in the hands of professionals. Advanced tasks can be complex and laborious. Trained and experienced professionals are needed so these tasks are done well. Expert technicians can spot the issues after a quick inspection, while ordinary individuals may not even notice them. Pros can conduct thorough checkups and diagnostic tests.

Moreover, they can handle technical jobs and have special tools ready, so the tasks are done quicker. They may also have spare parts with them, so necessary replacements are done faster. Technicians will also clean all components. Your generator will operate like new when technicians are done with it.

Modern life has made us highly dependent on machines, and these devices require power to function. Homes are equipped with appliances used for security, chores, work, comfort, and entertainment.
