J & D Unlimited llc

J & D Unlimited LLC is a Nashua, NH HVAC contractor that describes itself, on its own site, as offering air conditioning, water heater, boiler, and furnace work with over 25 years in the industry. It also holds an active New Hampshire HVAC license. Customers who hired them for appliance work describe careful, professional installs: one reviewer had a dishwasher installed and appreciated that the crew came back the same afternoon to adjust its positioning after finding an issue, while another credits the team with fixing a jammed garbage disposal and installing several appliances. A separate reviewer had four water-damaged windows replaced, praising a diligent, walk-through quote process and close attention to detail. All three reviews on file, spanning 2022 to 2023, are five-star and describe the crew as responsive, punctual, and trustworthy. The track record is short, so anyone considering them for heating or cooling work specifically should ask directly about that experience, since none of the reviews on file cover it. For window replacement, appliance installation, or similar repairs, the reviews so far are strongly positive; for HVAC work itself, the license and the company's own claimed experience are the clearest signals on file, and it's worth confirming scope before booking.
