Modern Home Heating and Cooling

No heat, no hot water, the coldest morning of the year — the homeowner who wrote that in a January 2026 review says Gene Engholm was at the house within twenty minutes and had them running again shortly after. Modern Home Heating and Cooling is a Hudson, New Hampshire HVAC shop that works on boilers, furnaces, ductless mini-splits and central air across southern New Hampshire, and it says Engholm founded it in 2021 after close to a decade in the trade. Its New Hampshire mechanical business licence is active on the state register, and Engholm's gas fitter licence is active there under his own name. Several reviewers came to him after another company had already been out: a May 2026 customer went looking for a second quote after being told the system had to be replaced, and an August 2026 review credits Larry with finding a fault another company had missed and replacing only the parts that needed it. In a January 2024 review, a homeowner described tests run both before and after the part went in, and nothing pushed that wasn't needed. The larger installs come with dates attached. A May 2025 customer had central air replaced across a roughly 6,500-square-foot, three-level home and business building and wrote that arrival and departure times held and the two weeks quoted were met. A September 2024 review describes a complete oil furnace and tank swap with hardly a break in heat or hot water, and in June 2025 another homeowner had three Mitsubishi mini-splits put in. When a steam boiler quit in February 2026, the customer wrote that a burner and boiler more than forty years old were replaced in a pinch and the original piping reworked to get more out of the new system. Smaller repairs draw the same detail. A tankless water heater was fixed in April 2026, with the manufacturer worked for the parts; in a March 2023 review, a heat exchanger that failed after three years in a nearly new house was replaced and proper duct work added where the builder's install had fallen short. On Google the company holds a 5-star average across 57 ratings, alongside a 5.0 from 10 ratings on Thumbtack. If another contractor has told you your system is finished and you want a second look before spending, this is the shop for that call. For a full replacement, settle the start and completion dates and exactly what the quote covers before the work begins.
