Wanjia Electric

WanJia Electric runs a storefront at 385 Washington St in Quincy, and the thing that jumps out across its reviews — many written in Mandarin — is how fast the mini-split jobs move: quote to finished ductless system in one to five days, including a same-day install on a multi-unit job. The company describes itself as family-run, and its focus is narrow and consistent: ductless mini-split and heat-pump installation, sales, and service for homes and small shops around Quincy and the Greater Boston area. Sixteen reviews on file from 2024 into 2025 land almost uniformly at five stars, with the recurring praise being a clean, tidy install and technicians described as professional and thorough — one customer had four split units across two storefronts done in a single day, another had three outdoor heat-pump condensers and six indoor heads finished in one visit. Several reviewers also credit the company with walking them through Mass Save's rebate paperwork, with one citing a roughly $10,000 subsidy on the installation. Before calling: the reviews are almost entirely about ductless mini-split and heat-pump work rather than general electrical wiring or panel jobs, so it's worth confirming they cover whatever specific job you have in mind.
