Know the Signs
Will My 100 Amp Panel Handle a Heat Pump or EV Charger?
Many homes in Upper Merion Township, including much of King of Prussia, went up in the second half of the 1900s with services sized for that time. A 100 amp panel was common, and it worked when the house had gas heat, a gas range and one window unit. Today many families want to switch to a heat pump, add central air, or charge an electric car overnight. Each of those adds a large, steady load. When the panel is already close to its limit, breakers trip, or there is simply no room for the new circuit. Older breakers can also wear out, and some panel brands from that era have known problems with breakers that don't trip when they should. A quick panel check from Electrical Hazards, Inc. tells you where you stand.
Signs It Is Time to Replace
- 100 amp service or smaller
- No space for new breakers
- Breakers trip with AC running
- Rust or heat marks inside
- Federal Pacific or Zinsco brand
How We Do It
Replacing a Panel in a Home or Townhouse
The steps depend on your home type. In a single-family house, we can often replace the panel and upgrade the service in one day once PECO disconnects the power. Townhouses and condos may share a meter bank or have rules about outside work, so we check those details first and plan around them. Every replacement starts with a load calculation, which tells us whether you need 200 amps or whether load management can make your current service work. Upper Merion Township handles the electrical permit, and we file it and meet the township inspector. We hold City of Philadelphia electrical contractor license #37352, and we replace worn grounding and service cable during the same visit when it needs it.
What We Plan For
- Load calculation first
- Single-family or townhouse setup
- Shared meter banks checked
- Township permit filed
- Grounding and cable reviewed
Why It Pays Off
Electrify Your Home Without Surprises
Switching from gas to electric equipment is a big change for an older electrical system. If you plan a heat pump, an induction range, an electric water heater or an EV charger, it is smarter to look at the panel first. We help you put those projects in order, so the panel upgrade happens once and each new appliance has a correctly sized circuit waiting for it. That approach avoids the most common surprise, which is buying new equipment and then finding out the house can't power it. It also helps when you sell, because buyers in this area often ask about EV readiness and panel size. A right-sized, labeled panel gives them a clear answer.

FAQ
Frequently Asked Questions
Who issues electrical permits in Upper Merion?
Upper Merion Township. We file the permit, schedule the inspection and meet the township inspector.
Can I add an EV charger without upgrading?
Sometimes. A load calculation shows whether your service has room. Load management devices can also help avoid a full upgrade.
Do townhouse panel replacements take longer?
They can, if several homes share the meter bank or the community has rules. We check those details first so install day stays on track.
Will a heat pump need a new panel?
Not always, but heat pumps add a large load. Many 100 amp homes need an upgrade, especially if they also plan EV charging.
How long does a replacement take?
Most single-family replacements take part of one working day. We give you the PECO shutoff date ahead of time.
