Arnest HVAC

Arnest HVAC is a Chelsea-based heating and cooling contractor that also does something most shops don't: marine air conditioning for boats, alongside the more usual furnace, boiler, heat pump and mini-split work it says it does across Greater Boston. In 2023 and 2024 Google reviews, customers describe routine calls handled cleanly: a same-day air conditioner fix at a reasonable price, preventative maintenance done just ahead of summer, and a furnace check that left one homeowner reassured about its condition. In 2023, one customer described using the company across commercial and marine HVAC projects, including an older-unit upgrade that saved money and some marine fabrication work. There isn't much of a written record to weigh yet — five reviews total and no licence or BBB information turned up — so there's little to flag as a concern. Anyone with commercial or marine HVAC work should ask directly about that experience, since only one reviewer mentions it.
