Mark Lindsay and Son Plumbing, Heating & Air Conditioning

Mark Lindsay and Son Plumbing, Heating & Air Conditioning has served Newfoundland, New Jersey, and neighboring Morris County communities for decades. The company holds state credentials as a licensed master plumber and HVAC contractor, and maintains a 4.8-star rating drawn from 1,688 customer reviews. Every day of the week, including weekends and holidays, the office answers calls around the clock, which means homeowners can reach a live dispatcher whether a furnace fails on a Sunday morning or a kitchen pipe bursts on a holiday evening. In addition to Newfoundland, the crew serves Denville, Rockaway, Boonton, and surrounding municipalities in the Jersey highlands region. For families and property managers who have found a contractor they can rely on year after year, the single point of contact and consistent crew make scheduling routine maintenance or unexpected repairs feel straightforward instead of stressful.

Unlike firms that specialize in a single trade, this contractor handles both plumbing and HVAC work under one roof. The website lists Lennox air conditioners, modern heat pumps, and high-efficiency furnaces alongside traditional gas and oil-fired boilers. For indoor air quality, the company offers the REME HALO whole-home air purification system, a UV-c and needle-point ionizer combination designed to address allergens and odors throughout ductwork. Smart thermostats and multi-zone control systems allow homeowners to manage separate temperature schedules for different floors or occupied rooms. The company also advertises oil-to-gas conversions for residents transitioning away from heating oil, and commercial HVAC services for smaller businesses in the region. Financing and membership plans are listed on the site, which may reduce the upfront cost of a full system replacement or allow a homeowner to spread preventive maintenance visits over a year rather than paying per visit.

Patrick McGovern called the office and had a technician arrive the same day to repair a boiler, finishing the work cleanly in a single trip without requiring a callback. In another review, Jon Vos arrived at a home late in the evening during subzero temperatures, diagnosed a frozen pipe, and restored water service within minutes, a scenario that many homeowners in the Jersey highlands know is not unusual during winter months. A third reviewer, Rob, cleaned boiler coils and then personally called the homeowner to answer follow-up questions about system pressure and hot water recovery, a step that the reviewer described as unexpectedly thorough. These specific names and scenarios are drawn directly from verified customer reviews and illustrate how the crew responds to common highlands emergencies, routine maintenance, and unexpected follow-up questions with the same level of care.
