A sub panel is a smaller electrical panel that connects to your main service panel and distributes power to a specific area of your home, such as a basement, addition, garage, or workshop. It helps safely manage electrical demand when the main panel is full or when dedicated circuits are needed in another part of the property.
A sub panel is essentially a secondary breaker box that extends your home’s electrical system. It is fed by your main service panel and allows power to be safely distributed to a specific area, such as a finished basement, home office, garage, or detached structure. Instead of overloading the main panel with additional breakers, a sub panel creates dedicated space for new circuits where they’re actually needed.
Sub panels are commonly installed when homeowners finish a basement, add a workshop, upgrade appliances, or need more outlets and lighting than the main panel can safely support. By moving some electrical demand to a sub panel, the system stays organized, easier to service, and safer overall. It also reduces crowding in the main breaker box, which can help prevent overheating and nuisance tripping.
In many Denver-area homes, sub panels are used to support basements or detached spaces where electrical needs increase over time. Installing one correctly requires proper sizing, grounding, and coordination with the existing electrical system to ensure safe, code-compliant operation.
Done! Plumbing, Heating, Cooling & Electric installs sub panels as part of planned electrical upgrades, basement finishes, and home expansions across the Denver metro. Our electricians evaluate current capacity, design the sub panel to support both immediate and future needs, and ensure the installation is completed correctly the first time.
The Done! Care Club is designed to simplify home maintenance by providing regular, scheduled service for essential systems—especially heating and cooling equipment that requires ongoing care to operate efficiently and reliably.
Care Club memberships include routine HVAC maintenance, such as heating and air conditioning tune-ups, along with plumbing system inspections. These scheduled visits are intended to identify wear, efficiency issues, and minor concerns early, helping reduce the risk of unexpected breakdowns or more disruptive repairs.
Membership benefits include:
For homeowners in the Denver area, regular HVAC maintenance is especially important due to wide seasonal temperature swings. Keeping heating and cooling systems properly maintained can support consistent performance and help extend equipment lifespan.
The Care Club is structured to provide ongoing system care while giving homeowners clear visibility into the condition of their plumbing and HVAC systems throughout the year.
*Services and benefits are determined by the equipment installed in the home and the selected Care Club plan.
An electrical map is a detailed layout of your home’s electrical circuits that shows which breakers control specific outlets, lights, and appliances. It helps quickly identify circuit loads, troubleshoot electrical issues, and ensure your system is safely supporting your home’s power needs.
An electrical map is a practical tool that documents how electricity is distributed throughout your home. It identifies which breaker controls each outlet, light, and hardwired appliance, giving you a clear picture of how your electrical system is organized and where power is being used.
Without an electrical map, diagnosing problems like tripped breakers, flickering lights, or overloaded circuits often turns into trial and error. Mapping your circuits allows electrical issues to be isolated quickly and helps reveal hidden problems, such as too many devices sharing a single circuit or older wiring struggling to handle modern electrical demands.
Electrical mapping is especially useful during home upgrades, basement finishes, appliance installations, or when adding new outlets or lighting. It ensures circuits are balanced correctly and that your system can safely support additional load before problems occur.
Done! Plumbing, Heating, Cooling & Electric performs electrical mapping as part of professional system evaluations and electrical upgrades. Our electricians trace circuits accurately, identify load issues, and document how your electrical system is actually being used, so decisions about repairs or upgrades are based on clear, reliable information.
Most flicker starts with something simple. These are the first things electricians typically rule out during an inspection:
If basic bulb or dimmer fixes don’t resolve the problem, electricians look beyond the fixture and into wiring connections, shared circuits, and the electrical panel to find the root cause.
When multiple lights flicker at the same time across rooms or circuits, the issue usually isn’t the bulb or switch. It’s often upstream, where electricity is distributed through your home.
Two common causes electricians see:
Sometimes the source isn’t inside the home at all. A failing meter base, service drop, or transformer can affect the entire property — and even nearby homes. If neighbors mention house lights flickering too, the issue may be on the utility side.
Diagnosing neutral and panel-related problems requires electrical testing and should only be handled by a licensed electrician.
It can be, depending on the cause.
Flicker from loose connections can create heat and arcing. Arcing occurs when electricity jumps across a gap instead of flowing through a secure contact, generating extremely high temperatures that can damage insulation or nearby materials.
Electrical faults that cause persistent flicker increase the risk of overheating and fire. Because these problems often develop gradually and out of sight, electricians focus on early diagnosis, before visible damage or failure occurs.
Call for help quickly if you notice:
If you’ve been wondering “why are my lights flickering” and the behavior keeps returning or gets worse, don’t ignore it. Even if lights stabilize temporarily, the underlying issue may still be present and can flare up under heavy load or temperature changes.
You can try a few simple checks without getting into risky territory:
For safety, set firm boundaries. Do not open your electrical panel, remove cover plates to access live wiring, or tighten service connections. If you notice heat, odor, buzzing, or visible damage, stop and call a professional.
If flickering continues after these checks, further troubleshooting requires electrical testing tools and panel access best left to a licensed electrician.
Call an electrician if:
Homes with older electrical panels may also lack the capacity for modern electrical loads. A professional inspection can identify weak connections, overloaded circuits, or aging components and recommend targeted repairs or panel upgrades.
Electricians start with a safety-focused inspection, checking fixtures, switches, and accessible connections for wear, heat marks, and loose terminations. They verify LED and dimmer compatibility and correct mismatches that cause shimmer.
They then measure voltage and circuit load, observe appliance start-up behavior, and test for neutral faults, voltage drop, and imbalance. Inside the panel, they inspect breakers, lugs, and connections for corrosion or improper torque. If the issue appears utility-related, electricians document findings and coordinate with the power company.
You’ll receive clear explanations, repair options, and guidance on next steps. The goal is simple: identify the true cause—whether it’s a fixture, wiring run, circuit, panel component, or service connection—and fix it correctly the first time.
If you notice multiple lights flickering across rooms or circuits, it’s time to bring in a professional electrician. That pattern often points to a shared wiring connection, neutral issue, or electrical panel problem that requires testing and panel access.
Persistent flicker that happens daily, worsens over time, or causes lights to brighten and dim unexpectedly should also be evaluated. These symptoms commonly indicate loose terminations or arcing connections that degrade with normal use.
If flickering appears alongside breaker trips, partial power loss, buzzing, heat, or burning smells, treat it as urgent. These are conditions electricians in Denver are trained to diagnose safely and correct before damage escalates.
For Denver homes and businesses, Done! electricians specialize in tracking down flickering light issues at the source—whether the problem is in a fixture, circuit, panel, or service connection.
