Excellent communication and professional!
Highly recommend!
Jason seemed to know the possible cause for the problem when I told him that the parts of the house were losing power gradually, and he was right!! He came out on the same day and fixed the problem (burnt crimp in junction box in the garage) within an hour!! Excellent!
They give an accurate read on what needs
to be done. They are a safety-first company
that shows up energetic & work...
They answered all our questions, let us know and talk through our options and didn't do any additional work without letting us know and approve the price difference for our requests, rather than telling us at the end of the job.
A+ work!
Update - Jason and Josh again came through for me. In the midst of a heat wave, they were able to come to the other end of the county and fix an electrical problem at my mother's house. Got the outlets for the portable AC and lift chair back working and made the wiring safer to boot.
Original - Could not ask for better. Jason installed a new 40 amp circuit and an EVo charger for our car. (No more slow 110 charging. Yeah!) While working in our breaker panel he noted a dangerous situation left by a previous contractor who upgraded our air conditioning.
(Side note kind of disappointing the inspector didn't notice that the other contractor put in a bigger breaker on a wire that was too small. Luckily the wire insulation had just started to bubble and it didn't catch fire.)
Within a week they were able to fit us in to replace the faulty circuit as well as rewire our garage lighting to eliminate some creative but scary runs of extension cords and re-purposed outlets. Now I have bright lights and when I look up, I don't see wires draped everywhere.
We connected with Jason of Dollens Electric through our equally excellent general contractor Dan Mackey. (Who by the way had nothing to do with the faulty circuit or the creative garage lighting.)
Lastly a thank you to Jason's son Josh who got to do the crawling under the house.
When should you upgrade your panel ?
Regular electrical maintenance appointments are essential to ensure panel electrical safety and efficiency. We are here to help and support you with all you may require to maintain your electric energy. Call today to schedule an appointment if:
- Your panel is 25 years older.
- Consider alternative options if modern arc fault circuit breakers are incompatible with your electrical panel.
- If you require more space to accommodate new equipment like an electric vehicle charging station or AC unit
- Older electrical panels, such as Zinsco, Federal Pacific, Stab Lock, and Challenger, no longer work as designed and may pose a risk of electrical fire.

Main Electrical Panel
The main electrical panel is the point through which electricity enters a building. It comprises an electric meter, main circuit breaker, and possibly smaller individual “branch circuit” circuit breakers. In some cases, depending on the builder or size of the home, the central panel may serve as the only electrical panel in the house.
Typically, the electrical panel in a house will be located on an outside wall. The power company delivers the power to a house through overhead or underground wires. Common locations for overhead-fed main panels are the side of the home closest to the utility overhead wires. Usually, underground-fed panels are on the side of the home, close to the front.
Apartments and Condominiums
The main electrical panels for managing the electricity and other utilities in apartments and condos may be located in a cabinet or closet on the exterior of the building, or they could be present in the underground garage. It is the responsibility of the Home Owners Association (HOA) to maintain them. The lifespan of these panels varies significantly based on the brand and installation methods used during their setup.
What is an Electrical Subpanel

A subpanel is a component of a house’s electrical system that holds branch circuits that power various appliances, plugs, and lights in a specific house area. House subpanels are essential for distributing electricity from the main panel to different areas of the house. They can be found in garages, laundry rooms, hallways, bedrooms, basements, or pantries.
Outdoor subpanels provide electricity to outdoor equipment such as air conditioning units, swimming pools, and outdoor cooking areas. They are usually attached to the outside walls of a house and differ from the main electrical panel. These subpanels prevent electrical issues and ensure that outdoor facilities have the necessary power supply.
Hiring a licensed professional electrician to install and operate subpanels is essential. They should follow local government rules related to building and safety, and adding subpanels around your home can save you money on your electrical project. You can place a subpanel where most of the wiring is to distribute electricity to the necessary areas.
Having multiple subpanels in different places is helpful because it eliminates the need to walk far to fix a tripped breaker, saving time and energy in the long run.
Safety Switches
Safety switches, also known as disconnects, are devices used to isolate electrical circuits and prevent the flow of electricity to equipment. They can be found near large appliances, such as outdoor AC units, and may contain circuit breakers or fuses.
Service With Integrity from Our Family To Yours
Electrical Grounding
Ensuring that older and improperly installed electrical panels are adequately grounded is essential. The chance of receiving a dangerous electric shock from the panel’s metal parts is higher without proper grounding.
Electricity flows from the source to the appliance through wires; sometimes, a faulty current can accidentally enter the ground. Ensuring proper grounding of your home’s electricity is crucial to prevent potential dangers. This allows any issues to be directed into the ground, preventing harm to your home.
