At Blessed Electric & Air, we offer commercial generator repair and maintenance services all over Texas. You’ve installed a generator because you don’t want a power outage to cause downtime in your office. So, the generator should be on standby. Once power goes out, your generator should kick right in.

What if your generator does not start? What if it disappoints you when you need it the most? This has happened to many of our clients, and that’s why we are discussing the common generator mistakes to avoid. If you can avoid all the mistakes, your chances of experiencing generator failure will be very slim.

Generator Mistakes to Avoid

Skipping or Postponing Maintenance

Due to the cost of commercial generator repair checks, many business owners tend to either skip or postpone maintenance checks. Some companies don’t even spend a dime on their generators unit it breaks down. When we service your generator, we’ll check the plugs, oil, coolants, and other components.

We will also assess its performance. We always change the engine oil. When the engine oil isn’t changed when due, it will gradually lose its viscosity and no longer protect the engine from friction. Less viscosity means more friction, which in turn increases heat and hasten wear and tear. Most importantly, we avert potential faults during maintenance.

Companies that try to save costs by skipping generator maintenance will eventually cough out a substantial amount of money for repairs, and it will be much more than the maintenance cost.

Purchasing an Oversized Generator

Some people prefer to buy a bigger generator than is needed with the hope of scaling up their business in the future. Of course, this is a smart idea, but there’s a limit to it. You must always load your generator with at least 35% of its capacity.

If not, the generator may get damaged because it won’t burn its fuel completely, and the engine will not heat up to the required temperature. It is called wet stacking. You don’t want to start repairing a generator that is not even up to six months old. Also, without adequate load, you won’t make efficient use of the fuel in your generator. The amount of fuel that should have been used to power 12 appliances will be used to power only three. How efficient is that?

Skipping Oil Change

Depending on their size, capacity, and usage, generators need an oil change every 50 -500 hours of usage. The oil is meant to keep all its components well-lubricated. As explained above, when the engine oil is left for a pretty long time, it will lose its viscosity and may not be able to lubricate generator engine components. In that situation, a breakdown may be inevitable.

Using Substandard Fuel

Low-quality fuel is much cheaper, and you may be tempted to go for it as a way to save a few dollars. Some people made the mistake and ended up regretting it. Substandard fuel reduces output, clogs injectors, and shortens the lifespan of your generator.

When your generator breaks down as a result of running low-quality fuel, you’ll pay much more than the peanuts you’ve been saving to fix it. This excludes the amount you’ll lose due to the downtime caused by the faulty generator.

Hiring a Non-Pro Technician for Maintenance or Repairs

Your choice of a technician has a role to play in the performance of your generator. Hiring an non-certified and unqualified generator technician could shorten the lifespan of your generator. It is always better to hire a certified technician like ours. It may cost you more, but it will be a better choice down the road.
