Maryland’s #1 Choice for Electrical Services

Is your electrical panel or wiring more than 20 years old? Are you looking to expand your current Maryland home? Did you recently purchase any new major appliances—such as a central air conditioner or heat pump? If so, it may be time to upgrade your electrical system with a heavy up from GAC Services.

What Is a Heavy Up?

A heavy up is an increase in amperage (power) of your main electrical service and is most commonly needed when your current electrical system cannot safely provide enough power to your home. Newer electrical equipment is built to handle multiple modern electronic appliances (home theaters, air conditioners, stoves, refrigerators, etc.) and other electrical devices commonly found in the home (TVs, lamps, computers, etc.). However, electrical panels and systems more than 20 years old were not built to handle such massive amounts of power—creating an electrical hazard throughout your home which could lead to an electrical fire.

If you’re looking to expand your home, or simply need more power to meet your electric needs, call the experts at GAC Services today—(240) 233-8498! Our licensed electricians undergo continuous training, so you can trust us to safely upgrade your electrical system.

How Do I Know If I Need a Heavy Up?

Even if you’re not planning on expanding your Maryland home or making any improvements to your major appliances, it is best to ask a licensed electrician if you could benefit from a heavy up. Some signs you need to call for a heavy up include, but are not limited to:

  • Your electrical panel is more than 20 years old
  • Your lights constantly flicker
  • Your circuit breakers frequently trip
  • You plan to expand your home (e.g. add a home office)
  • You want to add or upgrade major appliances (e.g. washer and dryer)
  • You need more circuits added to your electrical system

If you’re unsure if your home could improve its safety from a heavy up, give us a call! Not only do we have a full team of licensed electricians, but our staff is also trained to answer your electrical questions.

Benefits of Upgrading Your Electrical System

There are many benefits to upgrading your existing electrical system, including:

  • Increased safety – If the electrical system in your Maryland home is not equipped to handle as much amperage as you need, you could overload your system and cause an electrical fire. Protect your family and home with our electrical upgrade services!
  • Better electrical performance – Keep your lights from flickering and circuit breakers from tripping by scheduling a heavy up from GAC Services.
  • Future expansion – If you’re considering expanding your home, an electrical upgrade is most likely needed and an inspection must be completed by a licensed electrician.
  • More electrical power – Adding amperage to your home means you can use more electrical devices simultaneously in your home. Don’t be afraid to plug in your TV, home theater system, computers, electrical chargers, and more all at the same time.
  • And more!
