Common Questions
Our Green Meadows neighborhood has underground power lines. Does that make service upgrades more difficult?
Underground service laterals, common in suburban Johnston, are generally more reliable against weather but require different procedures. Upgrades often involve coordinating a new trench from the utility transformer to your meter socket. As master electricians, we handle the permitting with Johnston Community Development and coordinate the lateral pull with MidAmerican Energy to make the process seamless for you.
How can I prepare my home's electrical system for a Johnston ice storm or a summer brownout?
For winter ice storms that threaten long outages, a properly installed and permitted generator with a transfer switch is key. For summer brownouts from peak AC demand, whole-house surge protection is critical, as low voltage conditions can damage compressor motors. Ensuring your service entrance and grounding electrode system are in good condition helps your home handle these climate extremes.
I want to add a circuit. Do I really need a permit from the Johnston permit office for such a small job?
Yes, nearly all electrical work beyond a like-for-like replacement requires a permit. The Johnston Community Development Department enforces the NEC 2023, which includes crucial safety updates for AFCIs and GFCIs. As a licensee of the Iowa Electrical Examining Board, I pull the permits, schedule inspections, and ensure the work is documented. This protects your home's value and safety, and is non-negotiable for reputable professionals.
I have an older 150-amp panel. Can my Johnston house safely add a Level 2 EV charger and a new heat pump?
It depends on the panel's condition and brand. Many 2003-era panels are at capacity. A crucial safety check is for a recalled Federal Pacific panel, which poses a serious fire risk and must be replaced. Even with a safe panel, a 150-amp service may require a load calculation upgrade to support both a 240-volt EV charger and a heat pump without overloading the system.
My smart TVs and modems keep resetting during Johnston thunderstorms. Is this a problem with MidAmerican Energy or my house?
MidAmerican Energy maintains the grid to the meter, but Iowa's moderate to high surge risk from seasonal thunderstorms means transient voltage spikes are common. These surges travel into your home, degrading sensitive electronics. The solution is a professionally installed whole-house surge protector at your main panel, which defends all your circuits, not just individual outlet strips.
We live on the rolling plains near Johnston Commons. Could the soil affect our home's electrical grounding?
Yes, terrain matters. The rolling suburban plains can have varied soil composition, which directly impacts the conductivity of your grounding electrode system. Rocky or overly dry soil can create a high-impedance ground, compromising safety and surge dissipation. We test ground resistance to NEC standards and can install supplemental grounding rods if needed to ensure a low-resistance path to earth.
My Green Meadows home was built around 2003. Why do my lights dim when the microwave and air conditioner run together?
Homes from that era, now over 20 years old, were wired with NM-B Romex for the typical loads of 2003. Modern 2026 appliances—like large refrigerators, induction cooktops, and multiple computers—draw significantly more current. Your 150-amp panel may be operating at its functional limit. Upgrading branch circuits or the main service can eliminate this voltage drop and prevent nuisance breaker trips.
My power is out and I smell something burning from an outlet. How fast can a master electrician get to my house in Johnston?
For an emergency like a burning smell, which indicates a potential fire hazard, we dispatch immediately. From our staging near Johnston Commons, we can be en route via the I-35/I-80 corridor in minutes, with a typical 5-8 minute response to Green Meadows. Your first action should be to shut off the breaker for that circuit if it's safe to do so.
