What We Offer
OneStop Pro provides comprehensive residential generator services designed to keep your Wheaton home powered when you need it most. Our experienced team works with all major generator brands and can customize a backup power solution that fits your specific needs and budget.
Whole House Generator Installation
Our whole house generators automatically restore power to your entire home within seconds of an outage. We handle everything from initial consultation and load calculations to obtaining permits, installing the natural gas or propane connection, and setting up automatic transfer switches. Popular models we install include Generac Guardian series, Kohler residential generators, and Briggs & Stratton standby units. Each installation includes proper concrete pad preparation, electrical connections that meet all local codes, and comprehensive testing to ensure reliable operation.
Portable Generator Setup and Connections
For homeowners seeking a more budget-friendly option, we offer portable generator connections including transfer switch installation and inlet box setup. This allows you to safely connect a portable generator to your home’s electrical system without dangerous extension cords running through windows or doors. We’ll show you proper operation procedures and safety protocols to ensure your family’s protection during use.
Generator Maintenance and Service
Regular maintenance is crucial for generator reliability when you need it most. Our maintenance service includes oil and filter changes, spark plug replacement, battery testing and replacement, coolant system inspection, and comprehensive system testing. We recommend annual maintenance for most residential generators, though units that see heavy use may benefit from bi-annual service. Our technicians also perform software updates and inspect all electrical connections during each visit.

When your generator fails during a storm or outage, OneStop Pro provides emergency repair services to restore your backup power quickly. Common issues we address include starting problems, electrical faults, fuel system issues, and transfer switch malfunctions.

Frequently Asked Questions
How long does generator installation typically take?
Most residential generator installations take 1-2 days to complete. The timeline depends on factors like electrical panel modifications needed, gas line installation requirements, and permit approval processes. Whole house generators require concrete pad curing time, which may extend the project by a day. We’ll provide a detailed timeline during your initial consultation and keep you informed throughout the installation process.
What size generator do I need for my home?
Generator sizing depends on your home’s electrical load and which systems you want to power during an outage. We perform detailed load calculations considering essentials like refrigeration, heating/cooling, lighting, and sump pumps, plus any specific equipment you want to maintain. Most Wheaton homes need generators ranging from 14kW to 24kW for whole house coverage, though larger homes may require bigger units. We’ll assess your specific needs during our free consultation.
How often should I have my generator serviced?
We recommend annual maintenance for most residential generators to ensure reliable operation when you need backup power. This includes oil and filter changes, battery testing, system exercising, and comprehensive inspections. Generators that run frequently during outages or those in harsh environmental conditions may benefit from bi-annual service. Regular maintenance extends equipment life and maintains warranty coverage.
Can you service generators installed by other companies?
Yes, our certified technicians can service and repair generators regardless of who installed them. We work on all major brands including Generac, Kohler, Briggs & Stratton, and others.
