Many Boulder-area homes built between 1960 and 1975 have outdated electrical systems that can't safely support modern appliances like EV chargers or heat pumps. Older panels from Zinsco and Federal Pacific (Stab-Lok) pose significant safety risks and should be replaced, not repaired. Fortunately, Colorado’s Home Electrification & Appliance Rebate (HEAR) program can help lower your upgrade costs. Households earning 80% or less of the Area Median Income may qualify for a full rebate, while those earning between 80–150% may have 50% of the cost covered.
