Question DetailsAsked on 8/23/2013

how much does it cost to upgrade the electrical panel?

We are installing HVAC system in our house, roughly 3,500 sqft. We need to upgrade from 100 AMP to 200 AMP. I understand we need to replace the sub-panel and the main panel and install new R-4 breakers by new regulations

Click on the Home > Electrical link right below your question - you will find a number of questions like yours with answers about panel and service upgrades, and factors which affect cost.

I would get a couple of opinions from electricians on the general panel upgrade issue, unless you want to do that anyway for general upgrade purposes. If you are upgrading the main panel from 100 to 200A, then yes you have to upgrade to AFCI and GFCI breakers (as applicable) as part of the process.

However, if all you want to do it install power for the electric HVAC system, then it may be a lot cheaper to just upgrade the outside service capacity if necessary, and then install a dedicated secondary dedicated panel for HVAC system use, without touching the existing main breaker panel. Could make a 2 or 3:1 difference in cost, depending on your current situation.
