San Angelo Generator Installation Experts

We Install Generators Right

We’ve been handling electrical work in San Angelo for years. We’re licensed, insured, and we know the local codes that govern generator installations in Tom Green County.

Generator installation isn’t just about connecting wires. It requires proper sizing, gas line work, electrical panel integration, and city permits. We handle every step so your investment works when you need it most.

Our installations pass inspection the first time because we do the work right from the start. No shortcuts, no guesswork, no callbacks to fix what should have been done correctly initially.

Generator Installation Process

Here's How We Get You Powered Up

First, we evaluate your home’s electrical needs and recommend the right generator size. Most homes need between 16kW and 24kW to run everything comfortably, but we calculate your specific requirements rather than guess.

Next, we handle the permits with the city and coordinate with Atmos Energy if you need gas line work. We install the generator on a proper concrete pad, connect it to your electrical panel with a transfer switch, and run all the necessary wiring.

The final step is testing and commissioning. We simulate a power outage to make sure everything switches over smoothly, then show you how the system works. Your generator will automatically test itself weekly to ensure it’s always ready.

What's Included in Your Installation

Your generator installation includes everything needed for a complete, code-compliant system. We provide the concrete pad, electrical connections, transfer switch installation, and all necessary permits.

We work with top brands like Generac and Kohler because they build reliable units that last. These aren’t the portable generators you see at big box stores – they’re permanent installations designed to run for days or weeks if needed.

Every installation comes with manufacturer warranty protection and our commitment to service what we install. We’re not disappearing after the job is done. When you need maintenance or repairs, you’re calling the same team that put the system in.

How long does generator installation take in San Angelo?

Most residential generator installations take 1-2 days once permits are approved and materials arrive. The timeline depends on whether you need gas line work and how complex your electrical panel situation is. We handle the permit process with the city, which typically takes 3-5 business days. If you need a new gas line, Atmos Energy usually schedules that work within a week of our request. We coordinate all these moving parts so you’re not juggling multiple contractors and timelines.
Most San Angelo homes need between 16kW and 24kW for whole house coverage, but the right size depends on your specific electrical load. We calculate this based on your home’s square footage, HVAC system, appliances, and electrical panel capacity. A 20kW unit typically handles a 2,500 square foot home with central air, while larger homes or those with electric heat pumps might need 24kW or more. We don’t guess – we do the math to make sure your generator can handle everything you want to keep running.
Yes, generator installations require electrical permits from the City of San Angelo, and you’ll need approval from Atmos Energy if we’re connecting to your gas line. We handle all permit applications and inspections as part of our service. The city inspector needs to verify proper installation, grounding, and clearances before your system can be activated. Trying to skip permits creates problems when you file insurance claims or sell your home later. We make sure everything is documented and approved from the start.
Generator installation costs vary based on the unit size, electrical work required, and site conditions. A complete installation typically ranges from $8,000 to $15,000 including the generator, transfer switch, installation labor, and permits. Factors that affect price include distance from your electrical panel, whether you need gas line extensions, concrete work requirements, and local permit fees. We provide detailed estimates that break down all costs upfront, so you know exactly what you’re investing in before we start work.
Standby generators need annual maintenance similar to your car – oil changes, filter replacements, and system checks to ensure reliable operation. The generator automatically tests itself weekly for about 12 minutes, but professional service should happen yearly or every 200 hours of operation. This includes changing oil and filters, checking battery condition, inspecting connections, and verifying proper operation. Regular maintenance protects your warranty and prevents failures during actual outages when you need the system most.
A professionally installed whole house generator typically adds 3-5% to your home’s value and makes it more attractive to buyers. In areas like San Angelo where power outages are common, generators are increasingly viewed as essential rather than luxury items. Real estate agents report that homes with standby generators often sell faster and for asking price more frequently. The investment usually pays for itself through increased property value, plus you get years of reliable backup power while you live there.
