Electrical Company in Centennial, CO

Licensed Electricians Serving Centennial & the South Metro Area

Centennial became a city in 2001, but its homes were already middle-aged by then. Homes had been running their original electrical systems for decades before incorporation, and even much of the city's newer developments were built before EV chargers, home offices, and smart home systems were standard household considerations. We help close the gap between what these systems were designed for and what homeowners need from them now.

Rock Plumbing, Heating, Air & Electrical provides homeowners with:

• Electrical safety evaluations to assess your panel, wiring, and protection gaps
• Panel upgrades and service changes for homes that have outgrown their current capacity
• Circuit additions for home offices, appliances, hot tubs, and outdoor equipment
• EV charger installation, fully permitted and sized for your panel
• GFCI and AFCI protection upgrades to bring older wiring up to current safety standards
• Subpanel installation for garages, workshops, and additions
• Troubleshooting and repairs for outlets, fixtures, breakers, and wiring faults
• Fixture and device work, including ceiling fans, light fixtures, and smoke and CO detectors

Situations That Call for a Licensed Electrician

Sometimes the need is obvious. Often it isn't. These are the circumstances where you should call sooner rather than later to keep your home safe.

• You're buying or selling a home. An electrical inspection before closing gives both parties an accurate picture of the system's condition. For buyers, it surfaces issues before they become your responsibility. For sellers, it removes uncertainty from the negotiation table.
• You're finishing a basement or adding a room. New living space needs its own circuits. A properly wired addition starts with an electrical plan, not an extension cord and a hope that the existing circuit has enough capacity.
• You're renovating a kitchen or bathroom. Both rooms concentrate high-draw appliances and water in a tight space. Adding a dishwasher, a microwave, and updated lighting to circuits that weren't designed for that combined load needs an electrician involved before the walls close up.
• You haven't had an electrical inspection and your home is more than 20 years old. Connections loosen, protection standards advance, and household demand grows, often without any visible warning signs. An inspection gives you a current, accurate read on your system's condition.
• You're installing something that draws significant power. EV chargers, whole-home generators, central air conditioning, hot tubs — each requires a dedicated circuit sized correctly for that load, and in most cases, a permit. Getting the electrical right from the start protects both the equipment and your home.

Not sure whether your situation warrants a call? Reach out at (720) 410-5239 and we'll help you figure it out. For anything urgent, switch off the affected circuit at the breaker and leave it off until we can get to you. We offer 24/7 emergency service, with transparent after-hours pricing before we dispatch. Additionally, we have flexible financing options to help make emergency repairs and installations more manageable.

Our Electrical Work: What the Process Looks Like

From the first call to the final inspection, we keep the process clear and straightforward. Here's what to expect.

Larger Projects (panel upgrades, service changes, EV charger installation, circuit additions):

• We verify jurisdiction and submit the permit application to the correct authority.
• We schedule the work around your availability and coordinate the final inspection.
• We document everything. Permitted work protects you at closing and keeps your homeowner's insurance valid.

Smaller projects (fixture replacements, outlet repairs, smoke detector installation, device work):

• No permit required.
• Your technician arrives with the parts and materials to handle the most common repairs on the spot.
• We diagnose the issue, explain what we found and what it costs, and complete the work in the same visit.
• Before we leave, we test everything to confirm it's working correctly.

The Rock Comfort Club: Whole-Home Coverage, Year-Round

Most electrical problems don't announce themselves. They develop gradually. The Rock Comfort Club is designed to catch those issues before they become emergencies.

Furthermore, your electrical system doesn't operate in isolation. An overtaxed HVAC system draws more power. A water heater running inefficiently puts more demand on the circuits feeding it. Keeping all three systems maintained together means they're working with each other, not against each other.

Starting at $25 per month, membership includes:

• Annual electrical safety inspection (a $477 value) covering your panel, circuits, GFCI and AFCI protection, outlets, switches, and smoke and CO detectors
• Annual HVAC inspections — spring AC and fall furnace tune-ups included
• Whole-home plumbing inspection (a $250 value)
• 15% off all plumbing and HVAC repairs
• 5% off system replacements
• 48-hour service guarantee for emergency calls, with reduced after-hours rates for members
