What Factors Impact the Overall Cost of Installing a New Electrical Panel?

The cost of installing or replacing your home's circuit breaker depends a lot on if it was wired correctly the first time, as well as how old it is, and how readily available the breaker parts and switches are for purchase.

1. Type of Electrical Panel

With different sizes, in- and outdoor units, combinable with the meter and a range of available circuit spaces, it's best to get an expert’s input on which choice is best for your home.

2. If You Need to Upgrade Your Electrical Service

If you decide to upgrade to a larger electrical service flow, you may need to ensure you have your utility provider come out and upgrade your power supply or meter.

3. Whether You Need to Repair Existing Wiring or Install New Wiring

If you're replacing an electric circuit panel, it may require drilling or carpentry to arrange for adequate access to the newly installed panel. It may also require additional wiring to link any new subpanels added. Subpanels are necessary when a single circuit breaker panel can not cover an entire home and are essentially mini circuit panels.

Great seasonal service!

Great seasonal service today on our furnace and air handler/AC unit. Matt Miller did a very courteous and professional job describing all that he was doing and did and made additional recommendations on future service and care. He was very knowledgeable and had great interpersonal skills. We have used Mainstream for other projects as well and have always been satisfied with the work performed. I can say with honesty that they have not always been the cheapest, but they have always been the best. 'Good service is not cheap and cheap service is not good.' If you ever need a plumber, electrician or HVAC specialist, I highly recommend Mainstream.
