Electrical Heavy Ups

If you're a property owner, you know the importance of keeping your electrical systems up to date. One of the most important electrical services you may need is a heavy-up, which is an upgrade to your electrical system's capacity. If your home was built 20, 30, or 40+ years ago, your system may not be equipped to handle the new levels of electricity demand in the present day. At Castro Electrical Services, we can provide what is called a “heavy up” where we increase your home's capacity to maintain the levels of electricity your home needs. Located in Gaithersburg, MD we have provided electrical services to Montgomery County, MD since 2011.

What is an electrical heavy up?

An electrical heavy up is a process of upgrading the electrical service panel of a building or property to increase its capacity. This is done by adding a larger main circuit breaker and larger service cables to accommodate the additional electrical load. Heavy ups are commonly performed in older homes or commercial buildings that were not designed to handle the electrical demands of modern appliances and technology. The main reasons for a heavy up are to increase the electrical capacity, improve safety, and meet building codes.

The three most important pieces of information regarding electrical heavy ups are:

  • Heavy ups increase the capacity of the electrical service panel.
  • They are commonly performed in older buildings.
  • Heavy ups are done to improve safety and meet building codes.

Common Signs You May Need a Heavy Up

If your property is experiencing electrical issues such as circuit overloads or tripped breakers, it's likely that your electrical system is not capable of handling your power needs. A heavy-up service can solve these issues by increasing your electrical system's capacity.

The three most important pieces of information regarding why a property owner may need an electrical heavy up are:

  • The existing electrical service panel may be insufficient to meet the electrical demands of the property.
  • New appliances or technology may require more electricity to operate.
  • A heavy up may be required to meet building codes after renovations or additions.

What is involved in an electrical heavy up?

An electrical heavy up involves several steps. The first step is to evaluate the existing electrical service panel to determine if it can accommodate the required upgrades. If the existing panel is not suitable, a new panel will need to be installed. The next step is to remove the existing panel and install the new one. This includes running larger service cables to the panel and installing a larger main circuit breaker. Once the new panel is installed, the electrician will need to test and certify the installation to ensure that it meets safety standards and building codes. Our team at Castro Electrical Services can provide and analysis of your current system and complete the heavy-up services you need to get your property running efficiently.

Have had Castro out several times for troubleshooting as well as general electrical work (including outdoor receptacle and fan installation). I have been totally blown away by everyone’s professionalism, personable affect, and attention to detail. Communication is great. Prices appear very reasonable. They were able to diagnose a tricky safety hazard and remedy the situation thoroughly. I cannot recommend them enough!

Specifically I want to say a special thanks to Peter for his diagnostic work and attention to detail. He is also incredibly kind and clearly loves his work and the people he helps. He’s very smart and I trust him fully

It’s a pleasure to work with a service provider that knows how to get customer service right! Castro Electrical worked with me to get a critical electrical upgrade completed on a schedule that was important to me. Even if that meant inserting a job into an already full calendar, modifying the estimate and job specifications per my requirements, or having Peter and Carter (both managers) themselves come out and do the work. This team, together with their boss and owner Paul really differentiates themselves with their flexibility and customer focus while also being excellent electricians who know the job and how to do it with high quality!

Carter from Castro came out quickly to do an estimate and was very responsive throughout the process. He gave us different options for how to do the job, and did not push the more expensive one. Once the job was booked, they were able to complete it very quickly. The electricians were professional and courteous, and did a fantastic job. Will definitely use Castro again for future jobs.
