HVAC reviews in Waldwick, New Jersey

Highly recommend this local business. Jerry and his wife provide top tier customer service. They are incredibly responsive and professional in all aspects. I could tell that Jerry really cared about resolving my issue.

Thanks to Jerry and Steve we have a working bathroom again!! We've had a stuck diverter for awhile and were too lazy to get it fixed until one day we noticed the leaking started happening on the top by the handle. We called Gen III and met Steve. He was very knowledgeable and experienced in this field and worked very quickly to fix everything. Unfortunately our house was older so the parts he had were not compatible. Thankfully there was Jerry to the rescue. He was quickly able to track down the part we needed and brought it to us so in the end our bathroom was fixed the same day. Thanks for going the extra mile. We are so happy to be able to fully utilize our tub again.

5-Star Review
It’s incredibly rare to find a contractor who can expertly handle HVAC, plumbing, AND electrical work with just one phone call — but that’s exactly what you get with this company. After 25 years of homeownership and dealing with more contractors than I care to count, I can honestly say I’ve never experienced this level of service before.
From the very first call, their responsiveness has been outstanding. Scheduling is easy, they show up exactly when they say they will, and every single technician they’ve sent has been top-notch — professional, knowledgeable, clean, and genuinely courteous. They take the time to explain everything clearly, keep me updated throughout the job, and treat my home like it’s their own.
Whether it was installing a new AC unit, rewiring part of the house, or handling tricky plumbing repairs, the work has always been done right the first time, on budget, and with zero mess left behind. The entire team operates like a well-oiled machine, and their communication is second to none.
If you’re tired of juggling multiple contractors and want one reliable company that truly excels at all three trades, look no further. These guys have earned my trust completely — I won’t call anyone else for HVAC, plumbing, or electrical work ever again. Highly, highly recommend!
