Residential & Commercial Heating, Air Conditioning, & Plumbing
We proudly warranty all services and installations.
Knowledge, experience, & customer service you can count on
NSW Mechanical was founded by Jenna & Zach Berghof in 2021 with one thing in mind: our family. NSW is named after our children, Nina, Sadie, and Wyatt. As a family-owned small business, we take pride in providing excellent, reliable HVAC and plumbing services and installations—so much so that we warranty all labor for two years, and work with our suppliers to provide up to 12-year product warranties. With over 15 years of experience in the HVAC and plumbing industry, Zach has serviced and installed every type of residential and commercial system. We operate within a one-hour radius of our Milmay, New Jersey location, which spans the following counties: Cumberland, Atlantic, Salem, Gloucester, and Cape May County. We’re licensed, insured, and competitively priced—and we encourage all new customers to receive estimates from multiple companies. For a free estimate, call or email us today; you can also complete our short form here. Thank you, and we look forward to serving you!
Testimonials
“Grateful for such quality service on such short notice. Zach and his crew went above and beyond exceeding all expectations—four hours from start to finish installing brand new unit and ductwork! 10/10 recommend NSW Mechanical.”
— Brianna D.
“Got me up and running with hot water restored in no time flat. Great service!”
— Mike S.
“We first called NSW when our air conditioning stopped working. Zach diagnosed the issue immediately and quickly repaired it on site. When we eventually needed a new HVAC system, it was a no-brainer; we called NSW for a quote. They beat local competitors’ prices and replaced our indoor and outdoor units in one day. They kept our home spotless and did a beautiful job. Two years later, our system still works perfectly.
— Tina H.
“We had several companies try to fix our furnace to no avail. Zach found the incorrect wiring and bad ignition control in 5 minutes. His supplier provided it the same day and it’s been running since. Thank you!”
— Frank K.
“I highly recommend this company! Mike & his crew did an awesome job with all new ductwork, electronic zone dampers, and an electronic air purifier. Our airflow was so much better and cleaner afterward. So glad we called NSW after multiple companies tried to sell us new units we didn’t need! They were clean, fast, and did beautiful work.”
— Matthew R.
“NSW was great and personable. They provided fast and fair service and just all-around great work by great guys. They went above and beyond and did things they didn’t have to (cleaning up the yard around the work area, custom ductwork, etc.). I highly recommend this local business.”
— Jenni F.
“I highly recommend NSW Mechanical for your HVAC and plumbing needs. Zach and his crew are courteous and reliable. They went above and beyond to make sure we were happy with our new HVAC system and their installation was clean and tight. All ductwork was wrapped with insulation, which the local inspector was happy to see. Thank you, Zach, for a job well done!
— Jennifer L.
