One of the most common repair calls we receive starts with the same story:

“We had our generator installed by another company, and now it doesn’t work.”

It’s hard listening to homeowner after homeowner talk about the money they wasted on an installation that wasn’t done correctly.

💸 Wasted installation costs
🏨 Hotel expenses when failed inspections prevent power from being restored
🥩 Refrigerators and freezers full of spoiled food when the generator doesn’t start during an outage
⚠️ Expensive repairs to correct installation mistakes

The reality is that many companies selling generators don’t actually perform the entire installation themselves. They hire subcontractors for different parts of the project—an electrician for one piece, a plumber or gas contractor for another, and no on going service or warranty support.

At MDL Generator Supply, we handle the entire process.

From site evaluation and permitting to electrical work, fuel system installation, startup, inspections, warranty registration, and ongoing service, our team manages and completes every aspect of your generator installation.

Because generators are all we do, we understand how every part of the system works together. There is no finger-pointing between subcontractors when something goes wrong and no wondering who is responsible for fixing a problem.

When you invest in a standby generator, you deserve a company that specializes in generators—not a company that treats them as a side business.

Generators are our business, not just one of the things we do.
